It involved all of the world's great powers4 which were assembled in two opposing alliances: the Allies (centred around the Triple Entente) and the Central Powers (originally centered around the Triple Alliance).5 More than 70 million military personnel including 60 million Europeans were mobilised in one of the largest wars in history.67 More than 9 million combatants were killed largely because of great technological advances in firepower without corresponding advances in mobility. It was the second deadliest conflict in Western history.8 The assassination on 28 June 1914 of Archduke Franz Ferdinand of Austria the heir to the throne of Austria-Hungary was the proximate trigger of the war. Long-term causes such as imperialistic foreign policies of the great powers of Europe such as the German Empire the Austro-Hungarian Empire the Ottoman Empire the Russian Empire the British Empire France and Italy played a major role. Ferdinand's assassination by a Yugoslav nationalist resulted in a Habsburg ultimatum against the Kingdom of Serbia.910 Several alliances formed over the past decades were invoked so within weeks the major powers were at war; via their colonies the conflict soon spread around the world. On 28 July the conflict opened with the Austro-Hungarian invasion of Serbia1112 followed by the German invasion of Belgium Luxembourg and France; and a Russian attack against Germany. After the German march on Paris was brought to a halt the Western Front settled into a static battle of attrition with a trench line that changed little until 1917. In the East the Russian army successfully fought against the Austro-Hungarian forces but was forced back by the German army. Additional fronts opened after the Ottoman Empire joined the war in 1914 Italy and Bulgaria in 1915 and Romania in 1916. The Russian Empire collapsed in 1917 and Russia left the war after the October Revolution later that year. After a 1918 German offensive along the western front United States forces entered the trenches and the Allies drove back the German armies in a series of successful offensives. Germany agreed to a cease-fire on 11 November 1918 later known as Armistice Day. By the war's end four major imperial powersthe German Russian Austro-Hungarian and Ottoman Empireshad been militarily and politically defeated and had ceased to exist. The former two states lost a great amount of territory while the latter two were dismantled entirely. The map of central Europe was completely redrawn into several smaller states.13 The League of Nations was formed in the hope of preventing another such conflict. The European nationalism spawned by the war and the breakup of empires and the repercussions of Germany's defeat and the Treaty of Versailles led to the beginning of World War II in 1939.14 Contents 1 Etymology 2 Background 3 Chronology 3.1 Opening hostilities 3.1.1 Confusion among the Central Powers 3.1.2 African campaigns 3.1.3 Serbian campaign 3.1.4 German forces in Belgium and France 3.1.5 Asia and the Pacific 3.2 Early stages 3.2.1 Trench warfare begins 3.3 Naval war 3.4 Southern theatres 3.4.1 War in the Balkans 3.4.2 Ottoman Empire 3.4.3 Italian participation 3.4.4 Romanian participation 3.4.5 The role of India 3.5 Eastern Front 3.5.1 Initial actions 3.5.2 Russian Revolution 3.6 Central Powers proposal for starting peace negotiations 3.7 19171918 3.7.1 Developments in 1917 3.7.2 Entry of the United States 3.7.2.1 Non-Intervention 3.7.2.2 U.S. declaration of war on Germany 3.7.2.3 First active U.S. participation 3.7.3 Austrian offer of separate peace 3.7.4 German Spring Offensive of 1918 3.7.5 New states under war zone 3.7.6 Allied victory: summer and autumn 1918 3.8 Armistices and capitulations 3.8.1 Allied superiority and the stab-in-the-back legend November 1918 4 Technology 5 War crimes 5.1 Genocide and ethnic cleansing 5.1.1 Ottoman Empire 5.1.2 Russian Empire 5.2 Rape of Belgium 6 Soldiers' experiences 6.1 Prisoners of war 6.2 Military attachs and war correspondents 7 Support and opposition to the war 7.1 Support 7.2 Opposition 7.2.1 Conscription 8 Aftermath 8.1 Health and economic effects 8.2 Peace treaties and national boundaries 9 Legacy 9.1 Memorials 9.2 Cultural memory 9.3 Social trauma 9.4 Discontent in Germany 9.5 Views in the United States 9.6 New national identities 9.7 Economic effects 10 See also 10.1 Video 11 Notes 12 References 13 External links 13.1 Animated maps Etymology Before World War II the war was also known as The Great War The World War or The War in Europe.15 In France and Belgium it was sometimes referred to as La Guerre du Droit (the War for Justice) or La Guerre Pour la Civilisation / de Oorlog tot de Beschaving (the War to Preserve Civilisation) especially on medals and commemorative monuments. The term used by official histories of the war in Britain and Canada is First World War while American histories generally use the term World War I. The earliest known use of the term First World War appeared in September 1914 when German biologist and philosopher Ernst Haeckel said "there is no doubt that the course and character of the feared 'European War'" ... will become the first world war in the full sense of the word."16 The terms World War I and First World War both became standard (in the United States and Britain respectively) beginning in about 1940 to 1942; prior to that it was most commonly called The Great War.1718 Background Main article: Causes of World War I Map of the participants in World War I: Allied Powers in green Central Powers in orange and neutral countries in grey In the 19th century the major European powers had gone to great lengths to maintain a balance of power throughout Europe resulting by 1900 in a complex network of political and military alliances throughout the continent.5 These had started in 1815 with the Holy Alliance between Prussia Russia and Austria. Then in October 1873 German Chancellor Bismarck negotiated the League of the Three Emperors (German: Dreikaiserbund) between the monarchs of AustriaHungary Russia and Germany. This agreement failed because AustriaHungary and Russia could not agree over Balkan policy leaving Germany and AustriaHungary in an alliance formed in 1879 called the Dual Alliance. This was seen as a method of countering Russian influence in the Balkans as the Ottoman Empire continued to weaken.5 In 1882 this alliance was expanded to include Italy in what became the Triple Alliance.19 After 1870 European conflict was averted largely through a carefully planned network of treaties between the German Empire and the remainder of Europe orchestrated by Chancellor Bismarck. He especially worked to hold Russia at Germany's side to avoid a two-front war with France and Russia. With the ascension of Wilhelm II as German Emperor (Kaiser) Bismarck's system of alliances was gradually de-emphasised. For example the Kaiser refused to renew the Reinsurance Treaty with Russia in 1890. Two years later the Franco-Russian Alliance was signed to counteract the force of the Triple Alliance. In 1904 the United Kingdom sealed an alliance with France the Entente cordiale and in 1907 the United Kingdom and Russia signed the Anglo-Russian Convention. This system of interlocking bilateral agreements formed the Triple Entente.5 HMS Dreadnought. A naval arms race existed between the United Kingdom and Germany. German industrial and economic power had grown greatly after unification and the foundation of the empire in 1870. From the mid-1890s on the government of Wilhelm II used this base to devote significant economic resources to building up the Kaiserliche Marine (Imperial German Navy) established by Admiral Alfred von Tirpitz in rivalry with the British Royal Navy for world naval supremacy.20 As a result both nations strove to out-build each other in terms of capital ships. With the launch of HMS Dreadnought in 1906 the British Empire expanded on its significant advantage over its German rivals.20 The arms race between Britain and Germany eventually extended to the rest of Europe with all the major powers devoting their industrial base to the production of the equipment and weapons necessary for a pan-European conflict.21 Between 1908 and 1913 the military spending of the European powers increased by 50 percent.22 Austria-Hungary precipitated the Bosnian crisis of 19081909 by officially annexing the former Ottoman territory of Bosnia and Herzegovina which it had occupied since 1878. This greatly angered the Kingdom of Serbia and its patron the Pan-Slavic and Orthodox Russian Empire.23 Russian political manoeuvring in the region destabilised peace accords that were already fracturing in what was known as "the Powder keg of Europe".23 Ethno-linguistic map of AustriaHungary 1910 In 1912 and 1913 the First Balkan War was fought between the Balkan League and the fracturing Ottoman Empire. The resulting Treaty of London further shrank the Ottoman Empire creating an independent Albanian State while enlarging the territorial holdings of Bulgaria Serbia Montenegro and Greece. When Bulgaria attacked both Serbia and Greece on 16 June 1913 it lost most of Macedonia to Serbia and Greece and Southern Dobruja to Romania in the 33-day Second Balkan War further destabilising the region.24 Gavrilo Princip a Bosnian-Serb student was arrested immediately after he assassinated Archduke Franz Ferdinand of Austria On 28 June 1914 Gavrilo Princip a Bosnian-Serb student and member of Young Bosnia assassinated the heir to the Austro-Hungarian throne Archduke Franz Ferdinand of Austria in Sarajevo Bosnia.25 This began a period of diplomatic manoeuvring between Austria-Hungary Germany Russia France and Britain called the July Crisis. Wanting to end Serbian interference in Bosnia conclusively Austria-Hungary delivered the July Ultimatum to Serbia a series of ten demands which were intentionally unacceptable made with the intention of deliberately initiating a war with Serbia.26 When Serbia acceded to only eight of the ten demands levied against it in the ultimatum Austria-Hungary declared war on Serbia on 28 July 1914. Strachan argues "Whether an equivocal and early response by Serbia would have made any difference to Austria-Hungary's behaviour must be doubtful. Franz Ferdinand was not the sort of personality who commanded popularity and his demise did not cast the empire into deepest mourning".27 The Russian Empire unwilling to allow AustriaHungary to eliminate its influence in the Balkans and in support of its longtime Serb protgs ordered a partial mobilisation one day later.19 When the German Empire began to mobilise on 30 July 1914 France sporting significant animosity over the German conquest of Alsace-Lorraine during the Franco-Prussian War ordered French mobilisation on 1 August. Germany declared war on Russia on the same day.28 The United Kingdom declared war on Germany on 4 August 1914 following an "unsatisfactory reply" to the British ultimatum that Belgium must be kept neutral.29 Chronology Opening hostilities Confusion among the Central Powers The strategy of the Central Powers suffered from miscommunication. Germany had promised to support Austria-Hungary's invasion of Serbia but interpretations of what this meant differed. Previously tested deployment plans had been replaced early in 1914 but never tested in exercises. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia.30 Germany however envisioned Austria-Hungary directing the majority of its troops against Russia while Germany dealt with France. This confusion forced the Austro-Hungarian Army to divide its forces between the Russian and Serbian fronts. On 9 September 1914 the Septemberprogramm a possible plan which detailed Germany's specific war aims and the conditions that Germany sought to force upon the Allied Powers was outlined by German Chancellor Theobald von Bethmann-Hollweg. It was never officially adopted. African campaigns Lettow surrendering his forces to the British at Abercorn Main article: African theatre of World War I Some of the first clashes of the war involved British French and German colonial forces in Africa. On 7 August French and British troops invaded the German protectorate of Togoland. On 10 August German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the remainder of the war. The German colonial forces in German East Africa led by Colonel Paul Emil von Lettow-Vorbeck fought a guerrilla warfare campaign for the duration of World War I only surrendering two weeks after the armistice took effect in Europe.31 Serbian campaign Declaration of war. Austro-Hungarian government's telegram to the government of Serbia on 28 July 1914th. Main article: Serbian Campaign (World War I) The Serbian army fought the Battle of Cer against the invading Austro-Hungarians beginning on 12 August occupying defensive positions on the south side of the Drina and Sava rivers. Over the next two weeks Austrian attacks were thrown back with heavy losses which marked the first major Allied victory of the war and dashed Austro-Hungarian hopes of a swift victory. As a result Austria had to keep sizeable forces on the Serbian front weakening its efforts against Russia.32 German forces in Belgium and France German soldiers in a railway goods van on the way to the front in 1914. A message on the car spells out "Trip to Paris"; early in the war all sides expected the conflict to be a short one. Main article: Western Front (World War I) At the outbreak of the First World War the German army (consisting in the West of seven field armies) executed a modified version of the Schlieffen Plan designed to quickly attack France through neutral Belgium before turning southwards to encircle the French army on the German border.9 The plan called for the right flank of the German advance to converge on Paris and initially the Germans were very successful particularly in the Battle of the Frontiers (1424 August). By 12 September the French with assistance from the British forces halted the German advance east of Paris at the First Battle of the Marne (512 September). The last days of this battle signified the end of mobile warfare in the west.9 The French offensive into Germany launched on 7 August with the Battle of Mulhouse had limited success. In the east only one Field Army defended East Prussia and when Russia attacked in this region it diverted German forces intended for the Western Front. Germany defeated Russia in a series of battles collectively known as the First Battle of Tannenberg (17 August  2 September) but this diversion exacerbated problems of insufficient speed of advance from rail-heads not foreseen by the German General Staff. The Central Powers were thereby denied a quick victory and forced to fight a war on two fronts. The German army had fought its way into a good defensive position inside France and had permanently incapacitated 230000 more French and British troops than it had lost itself. Despite this communications problems and questionable command decisions cost Germany the chance of obtaining an early victory.33 Asia and the Pacific Main article: Asian and Pacific theatre of World War I New Zealand occupied German Samoa (later Western Samoa) on 30 August. On 11 September the Australian Naval and Military Expeditionary Force landed on the island of Neu Pommern (later New Britain) which formed part of German New Guinea. Japan seized Germany's Micronesian colonies and after the Siege of Tsingtao the German coaling port of Qingdao in the Chinese Shandong peninsula. Within a few months the Allied forces had seized all the German territories in the Pacific; only isolated commerce raiders and a few holdouts in New Guinea remained.3435 Early stages Trench warfare begins Main article: Western Front (World War I) Sir Winston Churchill with the Royal Scots Fusiliers 1916 Sunlight Soap ad placed in a trench (1915) Military tactics before World War I had failed to keep pace with advances in technology. These changes resulted in the building of impressive defence systems which out of date tactics could not break through for most of the war. Barbed wire was a significant hindrance to massed infantry advances. Artillery vastly more lethal than in the 1870s coupled with machine guns made crossing open ground very difficult.36 The Germans introduced poison gas; it soon became used by both sides though it never proved decisive in winning a battle. Its effects were brutal causing slow and painful death and poison gas became one of the most-feared and best-remembered horrors of the war. Commanders on both sides failed to develop tactics for breaching entrenched positions without heavy casualties. In time however technology began to produce new offensive weapons such as the tank.37 Britain and France were its primary users; the Germans employed captured Allied tanks and small numbers of their own design. After the First Battle of the Marne both Entente and German forces began a series of outflanking manoeuvres in the so-called "Race to the Sea". Britain and France soon found themselves facing entrenched German forces from Lorraine to Belgium's coast.9 Britain and France sought to take the offensive while Germany defended the occupied territories; consequently German trenches were generally much better constructed than those of their enemy. Anglo-French trenches were only intended to be "temporary" before their forces broke through German defences.38 Both sides attempted to break the stalemate using scientific and technological advances. On 22 April 1915 at the Second Battle of Ypres the Germans (in violation of the Hague Convention) used chlorine gas for the first time on the Western Front. Algerian troops retreated when gassed and a six kilometre (four mile) hole opened in the Allied lines that the Germans quickly exploited taking Kitcheners' Wood. Canadian soldiers closed the breach at the Second Battle of Ypres.39 At the Third Battle of Ypres Canadian and ANZAC troops took the village of Passchendaele.

On 1 July 1916 the British Army endured the bloodiest day in its history suffering 57470 casualties including 19240 dead on the first day of the Battle of the Somme. Most of the casualties occurred in the first hour of the attack. The entire Somme offensive cost the British Army almost half a million men.40 Neither side proved able to deliver a decisive blow for the next two years though protracted German action at Verdun throughout 191641 combined with the bloodletting at the Somme brought the exhausted French army to the brink of collapse. Futile attempts at frontal assault came at a high price for both the British and the French poilu (infantry) and led to widespread mutinies especially during the Nivelle Offensive.42 Canadian troops advancing behind a British Mark II tank at the Battle of Vimy Ridge. A French assault on German positions. Champagne France 1917. Throughout 191517 the British Empire and France suffered more casualties than Germany because of both the strategic and tactical stances chosen by the sides. At the strategic level while the Germans only mounted a single main offensive at Verdun the Allies made several attempts to break through German lines. At the tactical level German commander Erich Ludendorff's doctrine of "elastic defence" was well suited for trench warfare. This defence had a relatively lightly defended forward position and a more powerful main position farther back beyond artillery range from which an immediate and powerful counter-offensive could be launched.4344 Ludendorff wrote on the fighting in 1917 The 25th of August concluded the second phase of the Flanders battle. It had cost us heavily ... The costly August battles in Flanders and at Verdun imposed a heavy strain on the Western troops. In spite of all the concrete protection they seemed more or less powerless under the enormous weight of the enemys artillery. At some points they no longer displayed the firmness which I in common with the local commanders had hoped for. The enemy managed to adapt himself to our method of employing counter attacks ... I myself was being put to a terrible strain. The state of affairs in the West appeared to prevent the execution of our plans elsewhere. Our wastage had been so high as to cause grave misgivings and had exceeded all expectation.45 On the battle of the Menin Road Ridge Ludendorff wrote Another terrific assault was made on our lines on the 20 September ... The enemys onslaught on the 20th was successful which proved the superiority of the attack over the defence. Its strength did not consist in the tanks; we found them inconvenient but put them out of action all the same. The power of the attack lay in the artillery and in the fact that ours did not do enough damage to the hostile infantry as they were assembling and above all at the actual time of the assault.46 Officers and senior enlisted men of the Bermuda Militia Artillery's Bermuda Contingent Royal Garrison Artillery in Europe. Around 1.1 to 1.2 million soldiers from the British and Dominion armies were on the Western Front at any one time.47 A thousand battalions occupying sectors of the line from the North Sea to the Orne River operated on a month-long four-stage rotation system unless an offensive was underway. The front contained over 9600 kilometres (5965 mi) of trenches. Each battalion held its sector for about a week before moving back to support lines and then further back to the reserve lines before a week out-of-line often in the Poperinge or Amiens areas. In the 1917 Battle of Arras the only significant British military success was the capture of Vimy Ridge by the Canadian Corps under Sir Arthur Currie and Julian Byng. The assaulting troops were able for the first time to overrun rapidly reinforce and hold the ridge defending the coal-rich Douai plain.4849 Naval war Main article: Naval warfare of World War I The British Grand Fleet making steam for Scapa Flow 1914 At the start of the war the German Empire had cruisers scattered across the globe some of which were subsequently used to attack Allied merchant shipping. The British Royal Navy systematically hunted them down though not without some embarrassment from its inability to protect Allied shipping. For example the German detached light cruiser SMS Emden part of the East-Asia squadron stationed at Tsingtao seized or destroyed 15 merchantmen as well as sinking a Russian cruiser and a French destroyer. However the bulk of the German East-Asia squadronconsisting of the armoured cruisers Scharnhorst and Gneisenau light cruisers Nrnberg and Leipzig and two transport shipsdid not have orders to raid shipping and was instead underway to Germany when it encountered elements of the British fleet. The German flotilla along with Dresden sank two armoured cruisers at the Battle of Coronel but was almost destroyed at the Battle of the Falkland Islands in December 1914 with only Dresden and a few auxiliaries escaping but at the Battle of Ms a Tierra these too were destroyed or interned.50 A battleship squadron of the Hochseeflotte at sea Soon after the outbreak of hostilities Britain initiated a naval blockade of Germany. The strategy proved effective cutting off vital military and civilian supplies although this blockade violated generally accepted international law codified by several international agreements of the past two centuries.51 Britain mined international waters to prevent any ships from entering entire sections of ocean causing danger to even neutral ships.52 Since there was limited response to this tactic Germany expected a similar response to its unrestricted submarine warfare.53 The 1916 Battle of Jutland (German: Skagerrakschlacht or "Battle of the Skagerrak") developed into the largest naval battle of the war the only full-scale clash of battleships during the war and one of the largest in history. It took place on 31 May  1 June 1916 in the North Sea off Jutland. The Kaiserliche Marine's High Seas Fleet commanded by Vice Admiral Reinhard Scheer squared off against the Royal Navy's Grand Fleet led by Admiral Sir John Jellicoe. The engagement was a stand off as the Germans outmanoeuvred by the larger British fleet managed to escape and inflicted more damage to the British fleet than they received. Strategically however the British asserted their control of the sea and the bulk of the German surface fleet remained confined to port for the duration of the war.54 German U-boats attempted to cut the supply lines between North America and Britain.55 The nature of submarine warfare meant that attacks often came without warning giving the crews of the merchant ships little hope of survival.5556 The United States launched a protest and Germany modified its rules of engagement. After the notorious sinking of the passenger ship RMS Lusitania in 1915 Germany promised not to target passenger liners while Britain armed its merchant ships placing them beyond the protection of the "cruiser rules" which demanded warning and placing crews in "a place of safety" (a standard which lifeboats did not meet).57 Finally in early 1917 Germany adopted a policy of unrestricted submarine warfare realising the Americans would eventually enter the war.5558 Germany sought to strangle Allied sea lanes before the U.S. could transport a large army overseas but were only able to maintain five long range U-boats on station to limited effect.55 U-155 exhibited near Tower Bridge in London after the First World War. The U-boat threat lessened in 1917 when merchant ships began travelling in convoys escorted by destroyers. This tactic made it difficult for U-boats to find targets which significantly lessened losses; after the introduction of hydrophone and depth charges accompanying destroyers might attack a submerged submarine with some hope of success. The convoy system slowed the flow of supplies since ships had to wait as convoys were assembled. The solution to the delays was an extensive program to build new freighters. Troop ships were too fast for the submarines and did not travel the North Atlantic in convoys.59 The U-boats had sunk more than 5000 Allied ships at a cost of 199 submarines.60 World War I also saw the first use of aircraft carriers in combat with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918 as well as blimps for antisubmarine patrol.61 Southern theatres War in the Balkans Main articles: Balkans Campaign (World War I) Serbian Campaign (World War I) and Macedonian front (World War I) Austrian troops executing captured Serbians in 1917. Serbia lost about 850000 people a quarter of its prewar population and half its prewar resources.62 Faced with Russia Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses the Austrians briefly occupied the Serbian capital Belgrade. A Serbian counter attack in the battle of Kolubara however succeeded in driving them from the country by the end of 1914. For the first ten months of 1915 Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats however scored a coup by persuading Bulgaria to join in attacking Serbia. The Austro-Hungarian provinces of Slovenia Croatia and Bosnia provided troops for Austria-Hungary invading Serbia as well as fighting Russia and Italy. Montenegro allied itself with Serbia.63 Serbia was conquered in a little more than a month. The attack began in October when the Central Powers launched an offensive from the north; four days later the Bulgarians joined the attack from the east. The Serbian army fighting on two fronts and facing certain defeat retreated into Albania halting only once to make a stand against the Bulgarians. The Serbs suffered defeat near modern day Gnjilane in the Battle of Kosovo. Montenegro covered the Serbian retreat towards the Adriatic coast in the Battle of Mojkovac in 67 January 1916 but ultimately the Austrians conquered Montenegro too. Serbian forces were evacuated by ship to Greece.64 In late 1915 a Franco-British force landed at Salonica in Greece to offer assistance and to pressure the government to declare war against the Central Powers. Unfortunately for the Allies the pro-German King Constantine I dismissed the pro-Allied government of Eleftherios Venizelos before the Allied expeditionary force could arrive.65 The friction between the king of Greece and the Allies continued to accumulate with the National Schism which effectively divided Greece between regions still loyal to the king and the new provisional government of Venizelos located in Salonica. After intense diplomatic negotiations and an armed confrontation in Athens between Allied and royalist forces (an incident known as Noemvriana) the king of Greece resigned and his second son Alexander took his place. Venizelos returned to Athens on 29 May 1917 and Greece now unified officially joined the war on the side of the Allies. The entire Greek army was mobilized and began to participate in military operations against the Central Powers on the Macedonian front. The Entente in Macedonia.

Serbian rebels liberated for a short time the area between the Kopaonik mountains and the South Morava river. The uprising was crushed by joint efforts of Bulgarian and Austrian forces at the end of March 1917. The Macedonian Front proved static for the most part. Serbian forces retook part of Macedonia by recapturing Bitola on 19 November 1916. Only at the end of the conflict were the Entente powers able to break through after most of the German and Austro-Hungarian troops had withdrawn. The Bulgarians suffered their only defeat of the war at the Battle of Dobro Pole but days later they decisively defeated British and Greek forces at the Battle of Doiran avoiding occupation. Bulgaria signed an armistice on 29 September 1918.66 Hindenburg and Ludendorff concluded that the strategic and operational balance had now shifted decidedly against the Central Powers and a day after the Bulgarian collapse during a meeting with government officials insisted on an immediate peace settlement.67 The disappearance of the Macedonian front meant that the road to Budapest and Vienna was now opened for the 670000-strong army of general Franchet d'Esperey as the Bulgarian capitulation deprived the Central Powers of the 278 infantry battalions and 1500 guns (the equivalent of some 25 to 30 German divisions) that were previously holding the line.68 The German high command was able to respond by sending in only seven infantry and one cavalry division but these forces were far from sufficient for a front to be reestablished.68 Ottoman Empire Main article: Middle Eastern theatre of World War I A British artillery battery emplaced on Mount Scopus in the Battle of Jerusalem. The Ottoman Empire joined the Central Powers in the war the secret Ottoman-German Alliance having been signed in August 1914.69 It threatened Russia's Caucasian territories and Britain's communications with India via the Suez Canal. The British and French opened overseas fronts with the Gallipoli (1915) and Mesopotamian campaigns. In Gallipoli the Ottoman Empire successfully repelled the British French and Australian and New Zealand Army Corps (ANZACs). In Mesopotamia by contrast after the disastrous Siege of Kut (191516) British Imperial forces reorganised and captured Baghdad in March 1917. Further to the west in the Sinai and Palestine Campaign initial British setbacks were overcome when they captured Jerusalem in December 1917. The Egyptian Expeditionary Force under Field Marshal Edmund Allenby broke the Ottoman forces at the Battle of Megiddo in September 1918. Russian forest trench at the Battle of Sarikamish Russian armies generally had the best of it in the Caucasus. Enver Pasha supreme commander of the Ottoman armed forces was ambitious and dreamed of re-conquering central Asia and areas that had been lost to Russia previously. He was however a poor commander.70 He launched an offensive against the Russians in the Caucasus in December 1914 with 100000 troops; insisting on a frontal attack against mountainous Russian positions in winter he lost 86% of his force at the Battle of Sarikamish.71 General Yudenich the Russian commander from 1915 to 1916 drove the Turks out of most of the southern Caucasus with a string of victories.71 In 1917 Russian Grand Duke Nicholas assumed command of the Caucasus front. Nicholas planned a railway from Russian Georgia to the conquered territories so that fresh supplies could be brought up for a new offensive in 1917. However in March 1917 (February in the pre-revolutionary Russian calendar) the Czar was overthrown in the February Revolution and the Russian Caucasus Army began to fall apart. German soldiers in Jerusalem The army corps of Armenian volunteer units realigned under the command of General Tovmas Nazarbekian with Dro as a civilian commissioner of the Administration for Western Armenia. The front line had three main divisions commanded by Movses Silikyan Andranik and Mikhail Areshian. Another regular unit was under Colonel Korganian. More than 40000 men in Armenian partisan guerrilla detachments accompanied the main units.72 Instigated by the Arab bureau of the British Foreign and Commonwealth Office the Arab Revolt started with the help of Britain in June 1916 at the Battle of Mecca led by Sherif Hussein of Mecca and ended with the Ottoman surrender of Damascus. Fakhri Pasha the Ottoman commander of Medina resisted for more than two and half years during the Siege of Medina.73 Along the border of Italian Libya and British Egypt the Senussi tribe incited and armed by the Turks waged a small-scale guerrilla war against Allied troops. The British were forced to dispatch 12000 troops to oppose them in the Senussi Campaign. Their rebellion was finally crushed in mid-1916.74 Italian participation Main article: Italian Campaign (World War I) Further information: Battles of the Isonzo Austro-Hungarian mountain corps in Tyrol Italy had been allied with the German and Austro-Hungarian Empires since 1882 as part of the Triple Alliance. However the nation had its own designs on Austrian territory in Trentino Istria and Dalmatia. Rome had a secret 1902 pact with France effectively nullifying its alliance.75 At the start of hostilities Italy refused to commit troops arguing that the Triple Alliance was defensive in nature and that AustriaHungary was an aggressor. The Austro-Hungarian government began negotiations to secure Italian neutrality offering the French colony of Tunisia in return. The Allies made a counter-offer in which Italy would receive the Southern Tyrol Julian March and territory on the Dalmatian coast after the defeat of Austria-Hungary. This was formalised by the Treaty of London. Further encouraged by the Allied invasion of Turkey in April 1915 Italy joined the Triple Entente and declared war on Austria-Hungary on 23 May. Fifteen months later Italy declared war on Germany. Militarily the Italians had numerical superiority. This advantage however was lost not only because of the difficult terrain in which fighting took place but also because of the strategies and tactics employed. Field Marshal Luigi Cadorna a staunch proponent of the frontal assault had dreams of breaking into the Slovenian plateau taking Ljubljana and threatening Vienna. It was a Napoleonic plan which had no realistic chance of success in an age of barbed wire machine guns and indirect artillery fire combined with hilly and mountainous terrain. On the Trentino front the Austro-Hungarians took advantage of the mountainous terrain which favoured the defender. After an initial strategic retreat the front remained largely unchanged while Austrian Kaiserschtzen and Standschtzen engaged Italian Alpini in bitter hand-to-hand combat throughout the summer. The Austro-Hungarians counter attacked in the Altopiano of Asiago towards Verona and Padua in the spring of 1916 (Strafexpedition) but made little progress. Beginning in 1915 the Italians under Cadorna mounted eleven offensives on the Isonzo front along the Isonzo River north east of Trieste. All eleven offensives were repelled by the Austro-Hungarians who held the higher ground. In the summer of 1916 the Italians captured the town of Gorizia. After this minor victory the front remained static for over a year despite several Italian offensives. In the autumn of 1917 thanks to the improving situation on the Eastern front the Austro-Hungarian troops received large numbers of reinforcements including German Stormtroopers and the elite Alpenkorps. The Central Powers launched a crushing offensive on 26 October 1917 spearheaded by the Germans. They achieved a victory at Caporetto. The Italian army was routed and retreated more than 100 kilometres (60 mi.) to reorganise stabilising the front at the Piave River. Since in the Battle of Caporetto the Italian Army had heavy losses the Italian Government called to arms the so-called '99 Boys (Ragazzi del '99) that is all males who were 18 years old. In 1918 the Austro-Hungarians failed to break through in a series of battles on the Piave River and finally being decisively defeated in the Battle of Vittorio Veneto in October of that year. Austria-Hungary surrendered in early November 1918.7677 Romanian participation Main article: Romania during World War I Marshal Joffre inspecting Romanian troops Romania had been allied with the Central Powers since 1882. When the war began however it declared its neutrality arguing that because Austria-Hungary had itself declared war on Serbia Romania was under no obligation to join the war. When the Entente Powers promised Romania large territories of eastern Hungary (Transylvania and Banat) that had a large Romanian population in exchange for Romanias declaring war on the Central Powers the Romanian government renounced its neutrality and on 27 August 1916 the Romanian Army launched an attack against Austria-Hungary with limited Russian support. The Romanian offensive was initially successful pushing back the Austro-Hungarian troops in Transylvania but a counter attack by the forces of the Central Powers drove back the Russo-Romanian forces and as a result of the Battle of Bucharest the Central Powers occupied Bucharest on 6 December 1916. Fighting in Moldova continued in 1917 resulting in a costly stalemate for the Central Powers.7879 As Russia withdrew from the war in late 1917 as a result of the October Revolution Romania was forced to sign an armistice with the Central Powers on 9 December 1917. In January 1918 Romanian forces established control over Bessarabia as the Russian Army abandoned the province. Although a treaty was signed by the Romanian and the Bolshevik Russian government following talks between 59 March 1918 on the withdrawal of Romanian forces from Bessarabia within two months on 27 March 1918 Romania attached Bessarabia to its territory formally based on a resolution passed by the local assembly of the territory on the unification with Romania. Romania officially made peace with the Central Powers by signing the Treaty of Bucharest on 7 May 1918. Under that treaty Romania was obliged to cease war with the Central Powers and make small territorial concessions for Austria-Hungary ceding control of some passes in the Carpathian Mountains and grant oil concessions for Germany. In exchange the Central Powers recognised the sovereignty of Romania over Bessarabia. The treaty was renounced in October 1918 by the Alexandru Marghiloman government and Romania nominally re-entered the war on 10 November 1918. The next day the Treaty of Bucharest was nullified by the terms of the Armistice of Compigne.8081 Total Romanian deaths from 1914 to 1918 military and civilian within contemporary borders were estimated at 748000.82 The role of India Further information: Third Anglo-Afghan War and Hindu-German Conspiracy The war began with an unprecedented outpouring of loyalty and goodwill towards the United Kingdom from within the mainstream political leadership contrary to initial British fears of an Indian revolt.8384 The Indian Army in fact outnumbered the British Army at the beginning of the war. India under British rule contributed greatly to the British war effort by providing men and resources. This was done by the Indian Congress in hope of achieving self-government as India was very much under the control of the British. The United Kingdom disappointed the Indians by not providing self-governance leading to the Gandhian Era in Indian history. About 1.3 million Indian soldiers and labourers served in Europe Africa and the Middle East while both the Indian government and the princes sent large supplies of food money and ammunition. In all 140000 men served on the Western Front and nearly 700000 in the Middle East. Casualties of Indian soldiers totalled 47746 killed and 65126 wounded during World War I.85 Russian troops awaiting a German attack Eastern Front Initial actions Main article: Eastern Front (World War I) While the Western Front had reached stalemate the war continued in East Europe. Initial Russian plans called for simultaneous invasions of Austrian Galicia and German East Prussia. Although Russia's initial advance into Galicia was largely successful they were driven back from East Prussia by Hindenburg and Ludendorff at Tannenberg and the Masurian Lakes in August and September 1914.8687 Russia's less developed industrial base and ineffective military leadership was instrumental in the events that unfolded. By the spring of 1915 the Russians had retreated into Galicia and in May the Central Powers achieved a remarkable breakthrough on Poland's southern frontiers.88 On 5 August they captured Warsaw and forced the Russians to withdraw from Poland. Russian Revolution Main article: Russian Revolution (1917) Further information: North Russia Campaign Vladimir Illyich Lenin Despite the success of the June 1916 Brusilov Offensive in eastern Galicia89 dissatisfaction with the Russian government's conduct of the war grew. The success was undermined by the reluctance of other generals to commit their forces to support the victory. Allied and Russian forces were revived only temporarily with Romania's entry into the war on 27 August. German forces came to the aid of embattled Austro-Hungarian units in Transylvania and Bucharest fell to the Central Powers on 6 December. Meanwhile unrest grew in Russia as the Tsar remained at the front. Empress Alexandra's increasingly incompetent rule drew protests and resulted in the murder of her favourite Rasputin at the end of 1916. In March 1917 demonstrations in Petrograd culminated in the abdication of Tsar Nicholas II and the appointment of a weak Provisional Government which shared power with the Petrograd Soviet socialists. This arrangement led to confusion and chaos both at the front and at home. The army became increasingly ineffective.88 Russian Cossacks on the front 1915 Signing the Treaty of Brest-Litovsk (February 9 1918) are: 1. Count Ottokar von Czernin 2. Richard von Khlmann and 3. Vasil Radoslavov The war and the government became increasingly unpopular. Discontent led to a rise in popularity of the Bolshevik party led by Vladimir Lenin. He promised to pull Russia out of the war and was able to gain power. The triumph of the Bolsheviks in November was followed in December by an armistice and negotiations with Germany. At first the Bolsheviks refused the German terms but when Germany resumed the war and marched across Ukraine with impunity the new government acceded to the Treaty of Brest-Litovsk on 3 March 1918. It took Russia out of the war and ceded vast territories including Finland the Baltic provinces parts of Poland and Ukraine to the Central Powers.90 The manpower required for German occupation of former Russian territory may have contributed to the failure of the Spring Offensive however and secured relatively little food or other materiel. With the adoption of the Treaty of Brest-Litovsk the Entente no longer existed. The Allied powers led a small-scale invasion of Russia partly to stop Germany from exploiting Russian resources and to a lesser extent to support the "Whites" (as opposed to "Reds") in the Russian Civil War.91 Allied troops landed in Archangel and in Vladivostok. Central Powers proposal for starting peace negotiations 1917 German poster: Wilhelm II blames the Allies for fighting on. In December 1916 after ten brutal months of the Battle of Verdun and a successful offensive against Romania the Germans attempted to negotiate a peace with the Allies. Soon after U.S. President Wilson attempted to intervene as a peacemaker asking in a note for both sides to state their demands. Lloyd George's War Cabinet considered the German offer as a ploy to create divisions amongst the Allies. After initial outrage and much deliberation they took Wilson's note as a separate effort signalling that the U.S. was on the verge of entering the war against Germany following the "submarine outrages". While the Allies debated a response to Wilson's offer the Germans chose to rebuff it in favour of "a direct exchange of views". Learning of the German response the Allied governments were free to make clear demands in their response of 14 January. They sought restoration of damages the evacuation of occupied territories reparations for France Russia and Romania and a recognition of the principle of nationalities. This included the liberation of Italians Slavs Romanians Czecho-Slovaks and the creation of a "free and united Poland". On the question of security the Allies sought guarantees that would prevent or limit future wars complete with sanctions as a condition of any peace settlement.92 The negotiations failed and the Entente powers rejected the German offer because Germany did not state any specific proposals. To Wilson the Entente powers stated that they will not start peace negotiations until the Central powers evacuated all occupied Allied territories and provided indemnities for all damage which was done.93 19171918 French troopers under General Gouraud with their machine guns amongst the ruins of a cathedral near the Marne driving back the Germans. 1918 German film crew recording the action. Developments in 1917 Events of 1917 proved decisive in ending the war although their effects were not fully felt until 1918. The British naval blockade began to have a serious impact on Germany. In response in February 1917 the German General Staff convinced Chancellor Theobald von Bethmann-Hollweg to declare unrestricted submarine warfare with the goal of starving Britain out of the war. German planners estimated that unrestricted submarine warfare would cost Britain a monthly shipping loss of 600000 tons. While it was realised that the policy was also likely to bring the United States into the conflict British shipping losses would be so high that it would be forced to sue for peace after 5 to 6 months before American intervention could make an impact. In reality tonnage sunk rose above 500000 tons per month from February to July. It peaked at 860000 tons in April. After July the newly re-introduced convoy system became extremely effective in reducing the U-boat threat. Britain was safe from starvation while German industrial output fell and the United States troops joined the war in large numbers far earlier than Germany had anticipated. On 3 May 1917 during the Nivelle Offensive the weary French 2nd Colonial Division veterans of the Battle of Verdun refused their orders arriving drunk and without their weapons. Their officers lacked the means to punish an entire division and harsh measures were not immediately implemented. Then mutinies afflicted an additional 54 French divisions and saw 20000 men desert. The other Allied forces attacked but sustained tremendous casualties.94 However appeals to patriotism and duty as well as mass arrests and trials encouraged the soldiers to return to defend their trenches although the French soldiers refused to participate in further offensive action.95 Robert Nivelle was removed from command by 15 May replaced by General Philippe Ptain who suspended bloody large-scale attacks. Haut-Rhin France 1917 The victory of AustriaHungary and Germany at the Battle of Caporetto led the Allies at the Rapallo Conference to form the Supreme War Council to coordinate planning. Previously British and French armies had operated under separate commands. In December the Central Powers signed an armistice with Russia. This released large numbers of German troops for use in the west. With German reinforcements and new American troops pouring in the outcome was to be decided on the Western front. The Central Powers knew that they could not win a protracted war but they held high hopes for success based on a final quick offensive. Furthermore the leaders of the Central Powers and the Allies became increasingly fearful of social unrest and revolution in Europe. Thus both sides urgently sought a decisive victory.96 Entry of the United States Main article: American entry into World War I Non-Intervention The United States originally pursued a policy of non-intervention avoiding conflict while trying to broker a peace. When a German U-boat sank the British liner Lusitania in 1915 with 128 Americans aboard U.S. President Woodrow Wilson vowed "America is too proud to fight" and demanded an end to attacks on passenger ships. Germany complied. Wilson unsuccessfully tried to mediate a settlement. He repeatedly warned the U.S. would not tolerate unrestricted submarine warfare in violation of international law and U.S. ideas of human rights. Wilson was under pressure from former president Theodore Roosevelt who denounced German acts as "piracy".97 Wilson's desire to have a seat at negotiations at war's end to advance the League of Nations also played a role.98 Wilson's Secretary of State William Jennings Bryan whose opinions had been ignored resigned as he could no longer support the president's policy. Public opinion was angered at suspected German sabotage of Black Tom in Jersey City New Jersey and the Kingsland Explosion. In January 1917 Germany resumed unrestricted submarine warfare. The German Foreign minister in the Zimmermann Telegram told Mexico that U.S. entry was likely once unrestricted submarine warfare began and invited Mexico to join the war as Germany's ally against the United States. In return the Germans would send Mexico money and help it recover the territories of Texas New Mexico and Arizona that Mexico lost during the Mexican-American War 70 years earlier.99 Wilson released the Zimmerman note to the public and Americans saw it as a casus bellia cause for war. President Wilson before Congress announcing the break in official relations with Germany on 3 February 1917. U.S. declaration of war on Germany Wikisource has original text related to this article: Woodrow Wilson declares war on Germany After the sinking of seven U.S. merchant ships by submarines and the publication of the Zimmerman telegram Wilson called for war on Germany which the U.S. Congress declared on 6 April 1917.100 First active U.S. participation American soldiers on the Piave front hurling a shower of hand grenades into the Austrian trenches Two American soldiers run towards a bunker. The United States was never formally a member of the Allies but became a self-styled "Associated Power". The United States had a small army but after the passage of the Selective Service Act it drafted 2.8 million men101 and by summer 1918 was sending 10000 fresh soldiers to France every day. In 1917 the U.S. Congress gave U.S. citizenship to Puerto Ricans when they were drafted to participate in World War I as part of the Jones Act. Germany had miscalculated believing it would be many more months before they would arrive and that the arrival could be stopped by U-boats.102 The United States Navy sent a battleship group to Scapa Flow to join with the British Grand Fleet destroyers to Queenstown Ireland and submarines to help guard convoys. Several regiments of U.S. Marines were also dispatched to France. The British and French wanted U.S. units used to reinforce their troops already on the battle lines and not waste scarce shipping on bringing over supplies. The U.S. rejected the first proposition and accepted the second. General John J. Pershing American Expeditionary Forces (AEF) commander refused to break up U.S. units to be used as reinforcements for British Empire and French units. As an exception he did allow African-American combat regiments to be used in French divisions. The Harlem Hellfighters fought as part of the French 16th Division earning a unit Croix de guerre for their actions at Chateau-Thierry Belleau Wood and Sechault.103 AEF doctrine called for the use of frontal assaults which had long since been discarded by British Empire and French commanders because of the large loss of life.104 Austrian offer of separate peace In 1917 Emperor Charles I of Austria secretly attempted separate peace negotiations with Clemenceau with his wife's brother Sixtus in Belgium as an intermediary without the knowledge of Germany. When the negotiations failed his attempt was revealed to Germany resulting in a diplomatic catastrophe.105106 German Spring Offensive of 1918 Main article: Spring Offensive German General Erich Ludendorff drew up plans (codenamed Operation Michael) for the 1918 offensive on the Western Front. The Spring Offensive sought to divide the British and French forces with a series of feints and advances. The German leadership hoped to strike a decisive blow before significant U.S. forces arrived. The operation commenced on 21 March 1918 with an attack on British forces near Amiens. German forces achieved an unprecedented advance of 60 kilometres (40 miles).107 British and French trenches were penetrated using novel infiltration tactics also named Hutier tactics after General Oskar von Hutier. Previously attacks had been characterised by long artillery bombardments and massed assaults. However in the Spring Offensive of 1918 Ludendorff used artillery only briefly and infiltrated small groups of infantry at weak points. They attacked command and logistics areas and bypassed points of serious resistance. More heavily armed infantry then destroyed these isolated positions. German success relied greatly on the element of surprise.108 The front moved to within 120 kilometres (75 mi) of Paris. Three heavy Krupp railway guns fired 183 shells on the capital causing many Parisians to flee. The initial offensive was so successful that Kaiser Wilhelm II declared 24 March a national holiday. Many Germans thought victory was near. After heavy fighting however the offensive was halted. Lacking tanks or motorised artillery the Germans were unable to consolidate their gains. This situation was not helped by the supply lines now being stretched as a result of their advance.109 The sudden stop was also a result of the four Australian Imperial Force (AIF) divisions that were "rushed" down thus doing what no other army had done and stopping the German advance in its tracks. During that time the first Australian division was hurriedly sent north again to stop the second German breakthrough. British 55th (West Lancashire) Infantry Division troops blinded by tear gas during the Battle of Estaires 10 April 1918. General Foch pressed to use the arriving American troops as individual replacements. Pershing sought instead to field American units as an independent force. These units were assigned to the depleted French and British Empire commands on 28 March. A Supreme War Council of Allied forces was created at the Doullens Conference on 5 November 1917.110 General Foch was appointed as supreme commander of the allied forces. Haig Petain and Pershing retained tactical control of their respective armies; Foch assumed a coordinating role rather than a directing role and the British French and U.S. commands operated largely independently.110 Following Operation Michael Germany launched Operation Georgette against the northern English Channel ports. The Allies halted the drive with limited territorial gains for Germany. The German Army to the south then conducted Operations Blcher and Yorck broadly towards Paris. Operation Marne was launched on 15 July attempting to encircle Reims and beginning the Second Battle of the Marne. The resulting counterattack starting the Hundred Days Offensive marked their first successful Allied offensive of the war. By 20 July the Germans were back across the Marne at their Kaiserschlacht starting lines111 having achieved nothing. Following this last phase of the war in the West the German Army never again regained the initiative. German casualties between March and April 1918 were 270000 including many highly trained stormtroopers. Meanwhile Germany was falling apart at home. Anti-war marches became frequent and morale in the army fell. Industrial output was 53 percent of 1913 levels. New states under war zone In 1918 the internationally recognizedcitation needed Azerbaijan Democratic Republic Democratic Republic of Armenia and Democratic Republic of Georgia bordering the Ottoman Empire and Russian Empire were established as well as the unrecognized Centrocaspian Dictatorship and South West Caucasian Republic. Later these unrecognized states were eliminated by Azerbaijan and Turkey. Further information: Partitioning of the Ottoman Empire In 1918 the Dashnaks of the Armenian national liberation movement declared the Democratic Republic of Armenia (DRA) through the Armenian Congress of Eastern Armenians (unified form of Armenian National Councils) after the dissolution of the Transcaucasian Democratic Federative Republic. Tovmas Nazarbekian became the first Commander-in-chief of the DRA. Enver Pasha ordered the creation of a new army to be named the Army of Islam. He ordered the Army of Islam into the DRA with the goal of taking Baku on the Caspian Sea. This new offensive was strongly opposed by the Germans. In early May 1918 the Ottoman army attacked the newly declared DRA. Although the Armenians managed to inflict one defeat on the Ottomans at the Battle of Sardarabad the Ottoman army won a later battle and scattered the Armenian army. The Republic of Armenia signed the Treaty of Batum in June 1918.112 Allied victory: summer and autumn 1918 Main articles: Hundred Days Offensive and Weimar Republic The Allied counteroffensive known as the Hundred Days Offensive began on 8 August 1918. The Battle of Amiens developed with III Corps British Fourth Army on the left the French First Army on the right and the Australian and Canadian Corps spearheading the offensive in the centre through Harbonnires.113114 It involved 414 tanks of the Mark IV and Mark V type and 120000 men. They advanced 12 kilometres (7 miles) into German-held territory in just seven hours. Erich Ludendorff referred to this day as the "Black Day of the German army".113115 The Australian-Canadian spearhead at Amiens a battle that was the beginning of Germanys downfall46 helped pull the British armies to the north and the French armies to the south forward. While German resistance on the British Fourth Army front at Amiens stiffened after an advance as far as 14 miles (23 km) and concluded the battle there the French Third Army lengthened the Amiens front on 10 August when it was thrown in on the right of the French First Army and advanced 4 miles (6 km) liberating Lassigny in fighting which lasted until 16 August. South of the French Third Army General Charles Mangin (The Butcher) drove his French Tenth Army forward at Soissons on 20 August to capture eight thousand prisoners two hundred guns and the Aisne heights overlooking and menacing the German position north of the Vesle.116 Another "Black day" as described by Erich Ludendorff. Meanwhile General Byng of the Third British Army reporting that the enemy on his front was thinning in a limited withdrawal was ordered to attack with 200 tanks towards Bapaume opening the Battle of Albert with the specific orders of "To break the enemy's front in order to outflank the enemies present battle front" (opposite the British Fourth Army at Amiens).46 Allied leaders had now realised that to continue an attack after resistance had hardened was a waste of lives and it was better to turn a line than to try to roll over it. Attacks were being undertaken in quick order to take advantage of the successful advances on the flanks and then broken off when that attack lost its initial impetus.116 The British Third Army's 15-mile (24 km) front north of Albert progressed after stalling for a day against the main resistance line to which the enemy had withdrawn.117 Rawlinsons Fourth British Army was able to battle its left flank forward between Albert and the Somme straightening the line between the advanced positions of the Third Army and the Amiens front which resulted in recapturing Albert at the same time.116 On 26 August the British First Army on the left of the Third Army was drawn into the battle extending it northward to beyond Arras. The Canadian Corps already being back in the vanguard of the First Army fought their way from Arras eastward 5 miles (8 km) astride the heavily defended Arras-Cambrai before reaching the outer defences of the Hindenburg Line breaching them on the 28 and 29 August. Bapaume fell on the 29 August to the New Zealand Division of the Third Army and the Australians still leading the advance of the Fourth Army were again able to push forward at Amiens to take Peronne and Mont Saint-Quentin on 31 August. Further south the French First and Third Armies had slowly fought forward while the Tenth Army who had by now crossed the Ailette and was east of the Chemin des Dames was now near to the Alberich position of the Hindenburg Line.118 During the last week of August the pressure along a 70-mile (113 km) front against the enemy was heavy and unrelenting. From German accounts "Each day was spent in bloody fighting against an ever and again on-storming enemy and nights passed without sleep in retirements to new lines."116 Even to the north in Flanders the British Second and Fifth Armies during August and September were able to make progress taking prisoners and positions that were previously denied them.118 Close-up view of an American major in the basket of an observation balloon flying over territory near front lines On 2 September the Canadian Corps outflanking of the Hindenburg line with the breaching of the Wotan Position made it possible for the Third Army to advance and sent repercussions all along the Western Front. That same day Oberste Heeresleitung (OHL) had no choice but to issue orders to six armies for withdrawal back into the Hindenburg Line in the south behind the Canal du Nord on the Canadian-First Army's front and back to a line east of the Lys in the north giving up without a fight the salient seized in the previous April.119 According to Ludendorff We had to admit the necessity ... to withdraw the entire front from the Scarpe to the Vesle.120 In nearly four weeks of fighting since 8 August over 100000 German prisoners were taken 75000 by the BEF and the rest by the French. Since "The Black Day of the German Army" the German High Command realised the war was lost and made attempts for a satisfactory end. The day after the battle Ludenforff told Colonel Mertz "We cannot win the war any more but we must not lose it either." On 11 August he offered his resignation to the Kaiser who refused it and replied "I see that we must strike a balance. We have nearly reached the limit of our powers of resistance. The war must be ended." On 13 August at Spa Hindenburg Ludendorff Chancellor and Foreign Minister Hintz agreed that the war could not be ended militarily and on the following day the German Crown Council decided victory in the field was now most improbable. Austria and Hungary warned that they could only continue the war until December and Ludendorff recommended immediate peace negotiations to which the Kaiser responded by instructing Hintz to seek the mediation of the Queen of the Netherlands. Prince Rupprecht warned Prince Max of Baden "Our military situation has deteriorated so rapidly that I no longer believe we can hold out over the winter; it is even possible that a catastrophe will come earlier." On 10 September Hindenburg urged peace moves to Emperor Charles of Austria and Germany appealed to the Netherlands for mediation. On the 14 September Austria sent a note to all belligerents and neutrals suggesting a meeting for peace talks on neutral soil and on 15 September Germany made a peace offer to Belgium. Both peace offers were rejected and on 24 September OHL informed the leaders in Berlin that armistice talks were inevitable.118 September saw the Germans continuing to fight strong rear guard actions and launching numerous counter attacks on lost positions with only a few succeeding and then only temporarily. Contested towns villages heights and trenches in the screening positions and outposts of the Hindenburg Line continued to fall to the Allies with the BEF alone taking 30441 prisoners in the last week of September. Further small advances eastward would follow the Third Army victory at Ivincourt on 12 September the Fourth Armies at Epheny on 18 September and the French gain of Essigny-le-Grand a day later. On 24 September a final assault by both the British and French on a 4 mile (6 km) front would come within 2 miles (3 km) of St. Quentin.118 With the outposts and preliminary defensive lines of the Siegfried and Alberich Positions eliminated the Germans were now completely back in the Hindenburg Line. With the Wotan position of that line already breached and the Siegfried position in danger of being turned from the north the time had now come for an assault on the whole length of the line. The Allied attack on the Hindenburg Line began on 26 September including U.S. soldiers. The still-green American troops suffered problems coping with supply trains for large units on a difficult landscape.121 The following week cooperating French and American units broke through in Champagne at the Battle of Blanc Mont Ridge forcing the Germans off the commanding heights and closing towards the Belgian frontier.122 The last Belgian town to be liberated before the armistice was Ghent which the Germans held as a pivot until Allied artillery was brought up.123124 The German army had to shorten its front and use the Dutch frontier as an anchor to fight rear-guard actions. When Bulgaria signed a separate armistice on 29 September the Allies gained control of Serbia and Greece. Ludendorff having been under great stress for months suffered something similar to a breakdown. It was evident that Germany could no longer mount a successful defence.125126 Meanwhile news of Germany's impending military defeat spread throughout the German armed forces. The threat of mutiny was rife. Admiral Reinhard Scheer and Ludendorff decided to launch a last attempt to restore the "valour" of the German Navy. Knowing the government of Prince Maximilian of Baden would veto any such action Ludendorff decided not to inform him. Nonetheless word of the impending assault reached sailors at Kiel. Many rebelled and were arrested refusing to be part of a naval offensive which they believed to be suicidal. Ludendorff took the blamethe Kaiser dismissed him on 26 October. The collapse of the Balkans meant that Germany was about to lose its main supplies of oil and food. The reserves had been used up but U.S. troops kept arriving at the rate of 10000 per day.127 Having suffered over 6 million casualties Germany moved towards peace. Prince Maximilian of Baden took charge of a new government as Chancellor of Germany to negotiate with the Allies. Telegraphic negotiations with President Wilson began immediately in the vain hope that better terms would be offered than by the British and French. Instead Wilson demanded the abdication of the Kaiser. There was no resistance when the social democrat Philipp Scheidemann on 9 November declared Germany to be a republic. Imperial Germany was dead; a new Germany had been born: the Weimar Republic.128 Armistices and capitulations In the forest of Compigne after agreeing to the armistice that ended the war Foch is seen second from the right. The carriage seen in the background where the armistice was signed later was chosen as the symbolic setting of Ptain's June 1940 armistice. It was moved to Berlin as a prize but because of Allied bombing it was eventually moved to Crawinkel Thuringia where it was deliberately destroyed by SS troops in 1945.129 The collapse of the Central Powers came swiftly. Bulgaria was the first to sign an armistice on 29 September 1918 at Saloniki.130 On 30 October the Ottoman Empire capitulated at Moudros (Armistice of Mudros).130 On 24 October the Italians began a push which rapidly recovered territory lost after the Battle of Caporetto. This culminated in the Battle of Vittorio Veneto which marked the end of the Austro-Hungarian Army as an effective fighting force. The offensive also triggered the disintegration of Austro-Hungarian Empire. During the last week of October declarations of independence were made in Budapest Prague and Zagreb. On 29 October the imperial authorities asked Italy for an armistice. But the Italians continued advancing reaching Trento Udine and Trieste. On 3 November AustriaHungary sent a flag of truce to ask for an Armistice. The terms arranged by telegraph with the Allied Authorities in Paris were communicated to the Austrian Commander and accepted. The Armistice with Austria was signed in the Villa Giusti near Padua on 3 November. Austria and Hungary signed separate armistices following the overthrow of the Habsburg Monarchy. Following the outbreak of the German Revolution a republic was proclaimed on 9 November. The Kaiser fled to the Netherlands. On 11 November an armistice with Germany was signed in a railroad carriage at Compigne. At 11 a.m. on 11 November 1918; "the eleventh hour of the eleventh day of the eleventh month"; a ceasefire came into effect. Opposing armies on the Western Front began to withdraw from their positions. Canadian Private George Lawrence Price is traditionally regarded as the last soldier killed in the Great War: he was shot by a German sniper at 10:57 and died at 10:58.131 Allied superiority and the stab-in-the-back legend November 1918 In November 1918 the Allies had ample supplies of men and materiel to invade Germany yet at the time of the armistice no Allied force had crossed the German frontier and Berlin was still almost 900 mi (1400 km) from the Western Front. The Kaiser's armies had also retreated from the battlefield in good order which enabled Hindenburg and other senior German leaders to spread the story that their armies had not really been defeated. This resulted in the stab-in-the-back legend132133 which attributed Germany's losing the war not to its inability to continue fighting (even though up to a million soldiers were suffering from the 1918 flu pandemic and unfit to fight) but to the public's failure to respond to its "patriotic calling" and the intentional sabotaging of the war effort particularly by Jews Socialists and Bolsheviks. A formal state of war between the two sides persisted for another seven months until signing of the Treaty of Versailles with Germany on 28 June 1919. Later treaties with Austria Hungary Bulgaria and the Ottoman Empire were signed. However the latter treaty with the Ottoman Empire was followed by strife (the Turkish War of Independence) and a final peace treaty was signed between the Allied Powers and the country that would shortly become the Republic of Turkey at Lausanne on 24 July 1923. Some war memorials date the end of the war as being when the Versailles treaty was signed in 1919; by contrast most commemorations of the war's end concentrate on the armistice of 11 November 1918. Legally the last formal peace treaties were not signed until the Treaty of Lausanne. Under its terms the Allied forces divested Constantinople on 23 August 1923. Technology See also: Technology during World War I and Weapons of World War I Armoured cars The First World War began as a clash of 20-century technology and 19th-century tactics with inevitably large casualties. By the end of 1917 however the major armies now numbering millions of men had modernised and were making use of telephone wireless communication134 armoured cars tanks135 and aircraft. Infantry formations were reorganised so that 100 man companies were no longer the main unit of manoeuvre. Instead squads of 10 or so men under the command of a junior NCO were favoured. Artillery also underwent a revolution. In 1914 cannons were positioned in the front line and fired directly at their targets. By 1917 indirect fire with guns (as well as mortars and even machine guns) was commonplace using new techniques for spotting and ranging notably aircraft and the often overlooked field telephone. Counter-battery missions became commonplace also and sound detection was used to locate enemy batteries. Germany was far ahead of the Allies in utilising heavy indirect fire. She employed 150 and 210 mm howitzers in 1914 when the typical French and British guns were only 75 and 105 mm. The British had a 6 inch (152 mm) howitzer but it was so heavy it had to be hauled to the field in pieces and assembled. Germans also fielded Austrian 305 mm and 420 mm guns and already by the beginning of the war had inventories of various calibers of Minenwerfer ideally suited for trench warfare.136 Much of the combat involved trench warfare where hundreds often died for each yard gained. Many of the deadliest battles in history occurred during the First World War. Such battles include Ypres the Marne Cambrai the Somme Verdun and Gallipoli. The Haber process of nitrogen fixation was employed to provide the German forces with a constant supply of gunpowder in the face of British naval blockade.137 Artillery was responsible for the largest number of casualties138 and consumed vast quantities of explosives. The large number of head-wounds caused by exploding shells and fragmentation forced the combatant nations to develop the modern steel helmet led by the French who introduced the Adrian helmet in 1915. It was quickly followed by the Brodie helmet worn by British Imperial and U.S. troops and in 1916 by the distinctive German Stahlhelm a design with improvements still in use today. "Gas! Gas! Quick boys!... Fitting the clumsy helmets just in time; But someone still was yelling out and stumbling And flound'ring like a man in fire or lime... Dim through the misty panes and thick green light As under a green sea I saw him drowning."- Wilfred Owen DULCE ET DECORUM EST 1917139 The widespread use of chemical warfare was a distinguishing feature of the conflict. Gases used included chlorine mustard gas and phosgene. Few war casualties were caused by gas140 as effective countermeasures to gas attacks were quickly created such as gas masks. The use of chemical warfare and small-scale strategic bombing were both outlawed by the 1907 Hague Conventions and both proved to be of limited effectiveness141 though they captured the public imagination.142 The most powerful land-based weapons were railway guns weighing hundreds of tons apiece. These were nicknamed Big Berthas even though the namesake was not a railway gun. Germany developed the Paris Gun able to bombard Paris from over 100 kilometres (60 mi) though shells were relatively light at 94 kilograms (210 lb). While the Allies had railway guns German models severely out-ranged and out-classed them. RAF Sopwith Camel Fixed-wing aircraft were first used militarily by the Italians in Libya 23 October 1911 during the Italo-Turkish War for reconnaissance soon followed by the dropping of grenades and aerial photography the next year. By 1914 the military utility was obvious. They were initially used for reconnaissance and ground attack. To shoot down enemy planes anti-aircraft guns and fighter aircraft were developed. Strategic bombers were created principally by the Germans and British though the former used Zeppelins as well.143 Towards the end of the conflict aircraft carriers were used for the first time with HMS Furious launching Sopwith Camels in a raid to destroy the Zeppelin hangars at Tondern in 1918.144 German U-boats (submarines) were deployed after the war began. Alternating between restricted and unrestricted submarine warfare in the Atlantic they were employed by the Kaiserliche Marine in a strategy to deprive the British Isles of vital supplies. The deaths of British merchant sailors and the seeming invulnerability of U-boats led to the development of depth charges (1916) hydrophones (passive sonar 1917) blimps hunter-killer submarines (HMS R&-1 1917) forward-throwing anti-submarine weapons and dipping hydrophones (the latter two both abandoned in 1918).145 To extend their operations the Germans proposed supply submarines (1916). Most of these would be forgotten in the interwar period until World War II revived the need. British Vickers machine gun Old England first 1916 Trenches machine guns air reconnaissance barbed wire and modern artillery with fragmentation shells helped bring the battle lines of World War I to a stalemate. The British sought a solution with the creation of the tank and mechanised warfare. The first tanks were used during the Battle of the Somme on 15 September 1916. Mechanical reliability became an issue but the experiment proved its worth. Within a year the British were fielding tanks by the hundreds and showed their potential during the Battle of Cambrai in November 1917 by breaking the Hindenburg Line while combined arms teams captured 8000 enemy soldiers and 100 guns. Light automatic weapons and submachine guns were also introduced during the conflict such as the Lewis Gun the Browning automatic rifle and the Bergmann MP18. Manned observation balloons floating high above the trenches were used as stationary reconnaissance platforms reporting enemy movements and directing artillery. Balloons commonly had a crew of two equipped with parachutes.146 If there was an enemy air attack the crew could parachute to safety. At the time parachutes were too heavy to be used by pilots of aircraft (with their marginal power output) and smaller versions would not be developed until the end of the war; they were also opposed by British leadership who feared they might promote cowardice.147 Recognised for their value as observation platforms balloons were important targets of enemy aircraft. Johnson's Nieuport 16 armed with Le Prieur rockets for attacking observation balloons. To defend against air attack they were heavily protected by antiaircraft guns and patrolled by friendly aircraft; to attack them unusual weapons such as air-to-air rockets were even tried. Blimps and balloons contributed to air-to-air combat among aircraft because of their reconnaissance value and to the trench stalemate because it was impossible to move large numbers of troops undetected. The Germans conducted air raids on England during 1915 and 1916 with airships hoping to damage British morale and cause aircraft to be diverted from the front lines. The resulting panic took several squadrons of fighters from France.143147 Another new weapon flamethrowers were first used by the German army and later adopted by other forces. Although not of high tactical value they were a powerful demoralising weapon and caused terror on the battlefield. It was a dangerous weapon to wield as its heavy weight made operators vulnerable targets. Trench railways evolved to supply the enormous quantities of food water and ammunition required to support large numbers of soldiers in areas where conventional transportation systems had been destroyed. Internal combustion engines and improved traction systems for wheeled vehicles eventually rendered trench railways obsolete. War crimes Genocide and ethnic cleansing Ottoman Empire Main article: Ottoman casualties of World War I See also: Armenian Genocide Assyrian Genocide Greek genocide and Genocide denial The ethnic cleansing of the Ottoman Empire's Christian population with the most prominent among them being the deportation and massacres of Armenians (similar policies were enacted against the Assyrians and Ottoman Greeks) during the final years of the Ottoman Empire is considered genocide.148 The Ottomans saw the entire Armenian population as an enemy149 that had chosen to side with Russia at the beginning of the war.150 In early 1915 a number of Armenian nationalist groups such as the Armenakan Dashnak and Hunchak organisations joined the Russian forces and the Ottoman government used this as a pretext to issue the Tehcir Law. This authorised the deportation of the Armenians from eastern Anatolia to Syria between 1915 and 1917. The exact number of deaths is unknown although Balakian gives a range of 250000 to 1.5 million for the deaths of Armenians151 the International Association of Genocide Scholars estimates over 1 million.148 The government of Turkey has consistently rejected charges of genocide arguing that those who died were victims of inter-ethnic fighting famine or disease during the First World War.152 Belgian refugees in 1914. Russian Empire Main article: Anti-Jewish pogroms in the Russian Empire See also: Russian occupation of Eastern Galicia 1914-1915 Volhynia and Volga Germans Approximately 200000 Germans living in Volhynia and about 600000 Jews were deported by the Russian authorities.153154155 In 1916 an order was issued to deport around 650000 Volga Germans to the east as well but the Russian Revolution prevented this from being carried out.156 Many pogroms accompanied the Revolution of 1917 and the ensuing Russian Civil War 60000200000 civilian Jews were killed in the atrocities throughout the former Russian Empire.157158 Rape of Belgium Main article: Rape of Belgium In Belgium German troops in fear of French and Belgian guerrilla fighters or francs-tireurs massacred townspeople in Andenne (211 dead) Tamines (384 dead) and Dinant (612 dead). On 25 August 1914 the Germans set fire to the town of Leuven burned the library containing about 230000 books killed 209 civilians and forced 42000 to evacuate. These actions brought worldwide condemnation.159 Soldiers' experiences Main articles: List of surviving veterans of World War I World War I casualties Commonwealth War Graves Commission and American Battle Monuments Commission The First Contingent of the Bermuda Volunteer Rifle Corps to the 1 Lincolns training in Bermuda for the Western Front winter 19141915. One in four survived the war. The soldiers of the war were initially volunteers except for Italy but increasingly were conscripted into service. Britain's Imperial War Museum has collected more than 2500 recordings of soldiers' personal accounts and selected transcripts edited by military author Max Arthur have been published. The museum believes that historians have not taken full account of this material and accordingly has made the full archive of recordings available to authors and researchers.160 Surviving veterans returning home often found that they could only discuss their experiences amongst themselves. Grouping together they formed "veterans' associations" or "Legions". Prisoners of war This photograph shows an emaciated Indian Army soldier who survived the Siege of Kut. About 8 million men surrendered and were held in POW camps during the war. All nations pledged to follow the Hague Convention on fair treatment of prisoners of war. A POW's rate of survival was generally much higher than their peers at the front.161 Individual surrenders were uncommon. Large units usually surrendered en masse. At the Battle of Tannenberg 92000 Russians surrendered. When the besieged garrison of Kaunas surrendered in 1915 some 20000 Russians became prisoners. Over half of Russian losses were prisoners (as a proportion of those captured wounded or killed); for Austria-Hungary 32% for Italy 26% for France 12% for Germany 9%; for Britain 7%. Prisoners from the Allied armies totalled about 1.4 million (not including Russia which lost 2.-3.5clarification needed million men as prisoners.) From the Central Powers about 3.3 million men became prisoners.162 Germany held 2.5 million prisoners; Russia held 2.9 million; while Britain and France held about 720000. Most were captured just prior to the Armistice. The U.S. held 48000. The most dangerous moment was the act of surrender when helpless soldiers were sometimes gunned down.163164 Once prisoners reached a camp in general conditions were satisfactory (and much better than in World War II) thanks in part to the efforts of the International Red Cross and inspections by neutral nations. Conditions were terrible in Russia starvation was common for prisoners and civilians alike; about 1520% of the prisoners in Russia died. In Germany food was scarce but only 5% died.165166167 The Ottoman Empire often treated POWs poorly.168 Some 11800 British Empire soldiers most of them Indians became prisoners after the Siege of Kut in Mesopotamia in April 1916 4250 died in captivity.169 Although many were in very bad condition when captured Ottoman officers forced them to march 1100 kilometres (684 mi) to Anatolia. A survivor said: "we were driven along like beasts to drop out was to die."170 The survivors were then forced to build a railway through the Taurus Mountains. In Russia where the prisoners from the Czech Legion of the Austro-Hungarian army were released in 1917 they re-armed themselves and briefly became a military and diplomatic force during the Russian Civil War. While the Allied prisoners of the Central Powers were quickly sent home at the end of active hostilities the same treatment was not granted to Central Power prisoners of the Allies and Russia many of which had to serve as forced labor e.g. in France until 1920. They were only released after many approaches by the Red Cross to the Allied Supreme Council.171 There were still German prisoners being held in Russia as late as 1924.172 Military attachs and war correspondents Main article: Military attachs and war correspondents in the First World War Military and civilian observers from every major power closely followed the course of the war. Many were able to report on events from a perspective somewhat akin to modern "embedded" positions within the opposing land and naval forces. These military attachs and other observers prepared voluminous first-hand accounts of the war and analytical papers. For example former U.S. Army Captain Granville Fortescue followed the developments of the Gallipoli Campaign from an embedded perspective within the ranks of the Turkish defenders; and his report was passed through Turkish censors before being printed in London and New York.173 However this observer's role was abandoned when the U.S. entered the war as Fortescue immediately re-enlisted sustaining wounds at Forest of Argonne in the Meuse-Argonne Offensive September 1918.174 In-depth observer narratives of the war and more narrowly focused professional journal articles were written soon after the war; and these post-war reports conclusively illustrated the battlefield destructiveness of this conflict. This was not the first time the tactics of entrenched positions for infantry defended with machine guns and artillery became vitally important. The Russo-Japanese War had been closely observed by Military attachs war correspondents and other observers; but from a 21st century perspective it is now apparent that a range of tactical lessons were disregarded or not used in the preparations for war in Europe and throughout the Great War.175 Support and opposition to the war Main articles: Opposition to World War I and French Army Mutinies (1917) Support The war was primarily supported by nationalists industrial producers and imperialists. In the Balkans Yugoslav nationalists such as Yugoslav nationalist leader Ante Trumbi in the Balkans strongly supported the war desiring the freedom of Yugoslavs from Austria-Hungary and other foreign powers and the creation of an independent Yugoslavia.176 The Yugoslav Committee was formed in Paris on 30 April 1915 but shortly moved its office to London Trumbi led the Committee.176 In the Middle East Arab nationalism soared in Ottoman territories in response to the rise of Turkish nationalism during the war with Arab nationalist leaders advocating the creation of a pan-Arab state.177 In 1916 the Arab Revolt began in Ottoman-controlled territories of the Middle East in an effort to achieve independence.177 Italian nationalism was stirred by the outbreak of the war and was initially strongly supported by a variety of political factions. One of the most prominent and popular Italian nationalist supporters of the war was Gabriele d'Annunzio who promoted Italian irredentism and helped sway the Italian public to support intervention in the war.178 The Italian Liberal Party under the leadership of Paolo Boselli promoted intervention in the war on the side of the Allies and utilised the Dante Aligheri Society to promote Italian nationalism.179 A number of socialist parties initially supported the war when it began in August 1914.180 Initially European socialists became split on national lines with the conception of class conflict held by radical socialists such as Marxists and syndicalists being overstepped by their support for war.181 Once the war began Austrian British French German and Russian socialists followed the rising nationalist current by supporting their country's intervention in the war.182 Italian socialists were divided on whether to support the war or oppose it some were militant supporters of the war including Benito Mussolini and Leonida Bissolati.183 However the Italian Socialist Party decided to oppose the war after anti-militarist protestors had been killed resulting in a general strike called Red Week.184 The Italian Socialist Party purged itself of pro-war nationalist members including Mussolini.184 Mussolini a syndicalist who supported the war on grounds of irredentist claims on Italian-populated regions of Austria-Hungary formed the pro-interventionist Il Popolo d'Italia and the Fasci Riviluzionario d'Azione Internazionalista ("Revolutionary Fasci for International Action") in October 1914 that later developed into the Fasci di Combattimento in 1919 and the origin of fascism.185 Mussolini's nationalism enabled him to raise funds from Ansaldo (an armaments firm) and other companies to create Il Popolo d'Italia to convince socialists and revolutionaries to support the war.186 In April 1918 the Rome Congress of Oppressed Nationalities was held that included Czechoslovak Italian Polish Transylvanian and Yugoslav representatives that urged the Allies to support national self-determination for the peoples residing within Austria-Hungary.180 Opposition Shortly before the war British General Horace Smith-Dorrien predicted a catastrophic war which should be avoided at almost any cost. Rubble covered Sackville Street in Dublin after violence between Irish rebels and UK armed forces during the Easter Rising of 1916. 1917  Execution at Verdun at the time of the mutinies. The trade union and socialist movements had long voiced their opposition to a war which they argued meant only that workers would kill other workers in the interest of capitalism. Once war was declared however many socialists and trade unions backed their governments. Among the exceptions were the Bolsheviks the Socialist Party of America and the Italian Socialist Party and individuals such as Karl Liebknecht Rosa Luxemburg and their followers in Germany. There were also small anti-war groups in Britain and France. In Britain in 1914 the Public Schools Officers' Training Corps annual camp was held at Tidworth Pennings near Salisbury Plain. Head of the British Army Lord Kitchener was to review the cadets but the immenence of the war prevented him. General Horace Smith-Dorrien was sent instead. He surprised the two-or-three thousand cadets by declaring (in the words of Donald Christopher Smith a Bermudian cadet who was present) that war should be avoided at almost any cost that war would solve nothing that the whole of Europe and more besides would be reduced to ruin and that the loss of life would be so large that whole populations would be decimated. In our ignorance I and many of us felt almost ashamed of a British General who uttered such depressing and unpatriotic sentiments but during the next four years those of us who survived the holocaust-probably not more than one-quarter of us - learned how right the General's prognosis was and how courageous he had been to utter it. 187 Having voiced these sentiments did not hinder Smith-Dorien's career or preventing him from doing his duty in World War I to the best of his abilities. Many countries jailed those who spoke out against the conflict. These included Eugene Debs in the United States and Bertrand Russell in Britain. In the U.S. the Espionage Act of 1917 and Sedition Act of 1918 made it a federal crime to oppose military recruitment or make any statements deemed "disloyal". Publications at all critical of the government were removed from circulation by postal censors98 and many served long prison sentences for statements of fact deemed unpatriotic. A number of nationalists opposed intervention particularly within states that the nationalists held hostility to. Irish nationalists staunchly opposed taking part in intervention with the United Kingdom of Great Britain and Ireland.188 The war had begun amid the Home Rule crisis in Ireland that had begun in 1912 and by 1914 there was a serious possibility of an outbreak of civil war in Ireland between Irish unionists and republicans.188 Irish nationalists and Marxists attempted to pursue Irish independence culminating in the Easter Rising of 1916 with Germany sending 20000 rifles to Ireland in order to stir unrest in the United Kingdom.188 The UK government placed Ireland under martial law in response to the Easter Rising.189 Other opposition came from conscientious objectors  some socialist some religious  who refused to fight. In Britain 16000 people asked for conscientious objector status.190 Many suffered years of prison including solitary confinement and bread and water diets. Even after the war in Britain many job advertisements were marked "No conscientious objectors need apply". The Central Asian Revolt started in the summer of 1916 when the Russian Empire government ended its exemption of Muslims from military service.191 In 1917 a series of mutinies in the French army led to dozens of soldiers being executed and many more imprisoned. In Milan in May 1917 Bolshevik revolutionaries organised and engaged in rioting calling for an end to the war and managed to close down factories and stop public transportation.192 The Italian army was forced to enter Milan with tanks and machine guns to face Bolsheviks and anarchists who fought violently until May 23 when the army gained control of the city with almost fifty people killed (three of which were Italian soldiers) and over 800 people arrested.192 The Conscription Crisis of 1917 in Canada erupted when conservative Prime Minister Robert Borden brought in compulsory military service over the objection of French-speaking Quebecers.193 Out of approximately 625000 Canadians who served about 60000 were killed and another 173000 were wounded.194 In 1917 Emperor Charles I of Austria secretly entered into peace negotiations with the Allied powers with his brother-in-law Sixtus as intermediary without the knowledge of his ally Germany. He failed however because of the resistance of Italy.195 In September 1917 the Russian soldiers in France began questioning why they were fighting for the French at all and mutinied.196 In Russia opposition to the war led to soldiers also establishing their own revolutionary committees and helped foment the October Revolution of 1917 with the call going up for "bread land and peace". The Bolsheviks reached a peace treaty with Germany the peace of Brest-Litovsk despite its harsh conditions. The end of October 1918 in northern Germany saw the beginning of the German Revolution of 191819. Units of the German Navy refused to set sail for a last large-scale operation in a war which they saw as good as lost initiating the uprising. The sailors' revolt which then ensued in the naval ports of Wilhelmshaven and Kiel spread across the whole country within days and led to the proclamation of a republic on 9 November 1918 and shortly thereafter to the abdication of Kaiser Wilhelm II. Conscription As the war slowly turned into a war of attrition conscription was implemented in some countries. This issue was particularly explosive in Canada and Australia. In the former it opened a political gap between French-Canadians who claimed their true loyalty was to Canada and not the British Empire and the Anglophone majority who saw the war as a duty to both Britain and Canada. Prime Minister Robert Borden pushed through a Military Service Act provoking the Conscription Crisis of 1917. In Australia a sustained pro-conscription campaign by Prime Minister Billy Hughes caused a split in the Australian Labor Party and Hughes formed the Nationalist Party of Australia in 1917 to pursue the matter. Nevertheless the labour movement the Catholic Church and Irish nationalist expatriates successfully opposed Hughes' push which was rejected in two plebiscites. Conscription put into uniform nearly every physically fit man in Britain six of ten million eligible. Of these about 750000 lost their lives and 1700000 were wounded. Most deaths were to young unmarried men; however 160000 wives lost husbands and 300000 children lost fathers.197 Aftermath Main article: Aftermath of World War I Health and economic effects ..."Strange friend" I said "Here is no cause to mourn." "None" said the other "Save the undone years"... Wilfred Owen Strange Meeting 1918139 No other war had changed the map of Europe so dramatically  four empires disappeared: the German Austro-Hungarian Ottoman and the Russian. Four dynasties: the Hohenzollerns the Habsburg Romanovs and the Ottomans together with their ancillary aristocracies all fell after the war. Belgium and Serbia were badly damaged as was France with 1.4 million soldiers dead198 not counting other casualties. Germany and Russia were similarly affected.199 The war had profound economic consequences. Of the 60 million European soldiers who were mobilised from 19141918 8 million were killed 7 million were permanently disabled and 15 million were seriously injured. Germany lost 15.1% of its active male population AustriaHungary lost 17.1% and France lost 10.5%.200 About 750000 German civilians died from starvation caused by the British blockade during the war.201 By the end of the war famine had killed approximately 100000 people in Lebanon.202 The best estimates of the death toll from the Russian famine of 1921 run from 5 million to 10 million people.203 By 1922 there were between 4.5 million and 7 million homeless children in Russia as a result of nearly a decade of devastation from World War I the Russian Civil War and the subsequent famine of 19201922.204 Numerous anti-Soviet Russians fled the country after the Revolution; by the 1930s the northern Chinese city of Harbin had 100000 Russians.205 Thousands more emigrated to France England and the United States. Greek refugees from Smyrna 1922 American Red Cross nurses tend to 1918 flu pandemic patients in temporary wards set up inside Oakland Municipal Auditorium 1918. Diseases flourished in the chaotic wartime conditions. In 1914 alone louse-borne epidemic typhus killed 200000 in Serbia.206 From 1918 to 1922 Russia had about 25 million infections and 3 million deaths from epidemic typhus.207 Whereas before World War I Russia had about 3.5 million cases of malaria its people suffered more than 13 million cases in 1923.208 In addition a major influenza epidemic spread around the world. Overall the 1918 flu pandemic killed at least 50 million people.209210 Lobbying by Chaim Weizmann and fear that American Jews would encourage the USA to support Germany culminated in the British government's Balfour Declaration of 1917 endorsing creation of a Jewish homeland in Palestine.211 A total of more than 1172000 Jewish soldiers served in the Allied and Central Power forces in World War I including 450000 in Czarist Russia and 275000 in Austria-Hungary.212dead link The social disruption and widespread violence of the Revolution of 1917 and the ensuing Russian Civil War sparked more than 2000 pogroms in the former Russian Empire mostly in the Ukraine.213 An estimated 60000200000 civilian Jews were killed in the atrocities.214 In the aftermath of World War I Greece fought against Turkish nationalists led by Mustafa Kemal a war which resulted in a massive population exchange between the two countries under the Treaty of Lausanne.215 According to various sources216 several hundred thousand Pontic Greeks died during this period.217 Peace treaties and national boundaries After the war the Paris Peace Conference imposed a series of peace treaties on the Central Powers. The 1919 Treaty of Versailles officially ended the war. Building on Wilson's 14th point the Treaty of Versailles also brought into being the League of Nations on 28 June 1919.218219 In signing the treaty Germany acknowledged responsibility for the war agreeing to pay enormous war reparations and award territory to the victors. The "Guilt Thesis" became a controversial explanation of later events among analysts in Britain and the United States. The Treaty of Versailles caused enormous bitterness in Germany which nationalist movements especially the Nazis exploited with a conspiracy theory they called the Dolchstosslegende (Stab-in-the-back legend). The Weimar Republic lost the former colonial possessions and was saddled with accepting blame for the war as well as paying punitive reparations for it. Unable to pay them with exports (a result of territorial losses and postwar recession)220 Germany did so by borrowing from the United States. Runaway inflation in the 1920s contributed to the economic collapse of the Weimar Republic and the reparations were suspended in 1931 following the Stock Market Crash in 1929 and the beginnings of the Great Depression worldwide. AustriaHungary was partitioned into several successor states including Austria Hungary Czechoslovakia and Yugoslavia largely but not entirely along ethnic lines. Transylvania was shifted from Hungary to Greater Romania. The details were contained in the Treaty of Saint-Germain and the Treaty of Trianon. As a result of the Treaty of Trianon 3.3 million Hungarians came under foreign rule. Although the Hungarians made up 54% of the population of the pre-war Kingdom of Hungary only 32% of its territory was left to Hungary. Between 1920 and 1924 354000 Hungarians fled former Hungarian territories attached to Romania Czechoslovakia and Yugoslavia. The Russian Empire which had withdrawn from the war in 1917 after the October Revolution lost much of its western frontier as the newly independent nations of Estonia Finland Latvia Lithuania and Poland were carved from it. Bessarabia was re-attached to the Greater Romania as it had been a Romanian territory for more than a thousand years.221 The Ottoman Empire disintegrated and much of its non-Anatolian territory was awarded as protectorates of various Allied powers. The Turkish core was reorganised as the Republic of Turkey. The Ottoman Empire was to be partitioned by the Treaty of Svres in 1920. This treaty was never ratified by the Sultan and was rejected by the Turkish republican movement leading to the Turkish Independence War and ultimately to the 1923 Treaty of Lausanne. Legacy Main articles: World War I in popular culture and War memorial The first tentative efforts to comprehend the meaning and consequences of modern warfare began during the initial phases of the war and this process continued throughout and after the end of hostilities. Memorials The Beaumont Hamel Newfoundland Memorial in the Somme. Memorials were erected in thousands of villages and towns. Close to battlefields the improvised burial grounds were gradually moved to formal graveyards under the care of organisations such as the Commonwealth War Graves Commission the American Battle Monuments Commission the German War Graves Commission and Le Souvenir franais. Many of these graveyards also have central monuments to the missing or unidentified dead such as the Menin Gate memorial and the Thiepval Memorial to the Missing of the Somme. Surgeon Lt. Col. John McCrae of Canada author of In Flanders Fields died in 1918 of pneumonia. On 3 May 1915 during the Second Battle of Ypres Lieutenant Alexis Helmer was killed. At his graveside his friend John McCrae M.D. of Guelph Ontario Canada wrote the memorable poem In Flanders Fields as a salute to those who perished in the Great War. Published in Punch on 8 December 1915 it is still recited today especially on Remembrance Day and Memorial Day.222223 Cultural memory The First World War had a lasting impact on social memory. It was seen by many in Britain as signalling the end of Victorian England and across Europe many regarded it as a watershed moment.224 Historian Samuel Hynes explained: A generation of innocent young men their heads full of high abstractions like Honour Glory and England went off to war to make the world safe for democracy. They were slaughtered in stupid battles planned by stupid generals. Those who survived were shocked disillusioned and embittered by their war experiences and saw that their real enemies were not the Germans but the old men at home who had lied to them. They rejected the values of the society that had sent them to war and in doing so separated their own generation from the past and from their cultural inheritance.225 This has become the most common perception of the First World War perpetuated by the art cinema poems and stories published subsequently. Films such as All Quiet on the Western Front Paths of Glory and For King and Country have perpetuated the idea; while war-time films including Camrades Flanders Poppies and Shoulder Arms indicate that the most contemporary views of the war were overall far more positive.226 Likewise the art of Paul Nash John Nash Christopher Nevison and Henry Tonks in Britain painted a negative view of the conflict in keeping with the growing perception while popular war-time artists such as Muirhead Bone painted more serene and pleasant interpretations subsequently rejected as inaccurate.225 Several historianswho have since countered these interpretations: Siegfried Sassoon (May 1915) These beliefs did not become widely shared because they offered the only accurate interpretation of wartime events. In every respect the war was much more complicated than they suggest. In recent years historians have argued persuasively against almost every popular clich of the First World War. It has been pointed out that although the losses were devastating their greatest impact was socially and geographically limited. The many emotions other than horror experienced by soldiers in and out of the front line including comradeship boredom and even enjoyment have been recognised. The war is not now seen as a 'fight about nothing' but as a war of ideals a struggle between aggressive militarism and more or less liberal democracy. It has been acknowledged that British generals were often capable men facing difficult challenges and that it was under their command that the British army played a major part in the defeat of the Germans in 1918: a great forgotten victory.226 Though these historians have discounted as "myths"225227 these perceptions of the war they are nevertheless prevalent across much of society.citation needed They have dynamically changed according to contemporary influences reflecting in the 1950s perceptions of the war as 'aimless' following the contrasting Second World War and emphasising conflict within the ranks during times of class conflict in the 1960s.226 The majority of additions to the contrary are often rejected.226 Social trauma The social trauma caused by unprecedented rates of casualties manifested itself in different ways which have been the subject of subsequent historical debate.228 Some peoplewho were revolted by nationalism and its results and so they began to work towards a more internationalist world supporting organisations such as the League of Nations. Pacifism became increasingly popular. Others had the opposite reaction feeling that only strength and military could be relied upon in a chaotic and inhumane world. Anti-modernist views were an outgrowth of the many changes taking place in society. Book distributed by the U.S. War Department to veterans in 1919 The experiences of the war led to a collective trauma shared by many from all participating countries. The optimism of la belle poque was destroyed and those who fought in the war were referred to as the Lost Generation.229 For years afterwards people mourned the dead the missing and the many disabled.230 Many soldiers returned with severe trauma suffering from shell shock (also called neurasthenia now called posttraumatic stress disorder).231 Many more returned home with few after-effects; however their silence about the war contributed to the conflict's growing mythological status.228 In the United Kingdom mass-mobilisation large casualty rates and the collapse of the Edwardian era made a strong impression on society. Though many participants did not share in the experiences of combat or spend any significant time at the front or had positive memories of their service the images of suffering and trauma became the widely shared perception.228 Such historians as Dan Todman Paul Fussell and Samuel Heyns have all published works since the 1990s arguing that these common perceptions of the war are factually incorrect.228 Discontent in Germany The rise of Nazism and fascism included a revival of the nationalist spirit and a rejection of many post-war changes. Similarly the popularity of the Stab-in-the-back legend (German: Dolchstolegende) was a testament to the psychological state of defeated Germany and was a rejection of responsibility for the conflict. This conspiracy theory of betrayal became common and the German populace came to see themselves as victims. The Dolchstolegende's popular acceptance in Germany played a significant role in the rise of Nazism. A sense of disillusionment and cynicism became pronounced with nihilism growing. Many believed the war heralded the end of the world as they had known it because of the high fatalities among a generation of men the dissolution of governments and empires and the collapse of capitalism and imperialism. Communist and socialist movements around the world drew strength from this theory and enjoyed a new level of popularity. These feelings were most pronounced in areas directly or harshly affected by the war. Out of German discontent with the still controversial Treaty of Versailles Adolf Hitler was able to gain popularity and power.232233 World War II was in part a continuation of the power struggle never fully resolved by the First World War; in fact it was common for Germans in the 1930s and 1940s to justify acts of international aggression because of perceived injustices imposed by the victors of the First World War.234235236 The establishment of the modern state of Israel and the roots of the continuing Israeli-Palestinian Conflict are partially found in the unstable power dynamics of the Middle East which resulted from World War I.237 Prior to the end of the war the Ottoman Empire had maintained a modest level of peace and stability throughout the Middle East.238 With the fall of Ottoman government power vacuums developed and conflicting claims to land and nationhood began to emerge.239 The political boundaries drawn by the victors of the First World War were quickly imposed sometimes after only cursory consultation with the local population. In many cases these continue to be problematic in the 21st-century struggles for national identity.240241 While the dissolution of the Ottoman Empire at the end of World War I was pivotal in contributing to the modern political situation of the Middle East including the Arab-Israeli conflict242243244 the end of Ottoman rule also spawned lesser known disputes over water and other natural resources.245 Further information: SykesPicot Agreement Views in the United States U.S. intervention in the war as well as the Wilson administration became deeply unpopular. This was reflected in the U.S. Senate's rejection of the Versailles treaty and membership in the League of Nations. In the interwar era a consensus arose that U.S. intervention was a mistake and the Congress passed laws in an attempt to preserve U.S. neutrality in any future conflict. Polls taken in 1937 and the opening months of World War II established that nearly 60% regarded the intervention as a mistake with only 28% opposing that view. But in the period between the fall of France and the attack on Pearl Harbor public opinion changed dramatically and for the first time a narrow plurality rejected the idea that the war was a mistake.246 New national identities Poland reemerged as an independent country after more than a century. As a "minor Entente nation" and the country with the largest casualties per head247248249 the Kingdom of Serbia and its dynasty became the backbone of the new multinational state the Kingdom of Serbs Croats and Slovenes (later renamed Yugoslavia). Czechoslovakia became a new nation. Russia became the Soviet Union and lost Finland Estonia Lithuania and Latvia which became independent countries. The Ottoman Empire was soon replaced by Turkey and several other countries in the Middle East. In the British Empire the war unleashed new forms of nationalism. In Australia and New Zealand the Battle of Gallipoli became known as those nations' "Baptism of Fire". It was the first major war in which the newly established countries fought and it was one of the first times that Australian troops fought as Australians not just subjects of the British Crown. Anzac Day commemorating the Australian and New Zealand Army Corps celebrates this defining moment.250251 After the Battle of Vimy Ridge where the Canadian divisions fought together for the first time as a single corps Canadians began to refer to theirs as a nation "forged from fire".252 Having succeeded on the same battleground where the "mother countries" had previously faltered they were for the first time respected internationally for their own accomplishments. Canada entered the war as a Dominion of the British Empire and remained so afterwards although she emerged with a greater measure of independence.253254 While the other Dominions were represented by Britain Canada was an independent negotiator and signatory of the Versailles Treaty. Economic effects One of the most dramatic effects of the war was the expansion of governmental powers and responsibilities in Britain France the United States and the Dominions of the British Empire. In order to harness all the power of their societies new government ministries and powers were created. New taxes were levied and laws enacted all designed to bolster the war effort; many of which have lasted to this day. Similarly the war strained the abilities of the formerly large and bureaucratised governments such as in AustriaHungary and Germany; however any analysis of the long-term effects were clouded by the defeat of these governments. Germany 1923: banknotes had lost so much value that they were used as wallpaper. Millions of middle-class Germans were ruined by the hyperinflation. When the war began in 1914 a dollar was worth 4.2 marks. By November 1923 the dollar was at 4.2 trillion255 marks.256 Gross domestic product (GDP) increased for three Allies (Britain Italy and U.S.) but decreased in France and Russia in neutral Netherlands and in the main three Central Powers. The shrinkage in GDP in Austria Russia France and the Ottoman Empire reached 30 to 40%. In Austria for example most of the pigs were slaughtered and at war's end there was no meat. All nations had increases in the government's share of GDP surpassing fifty percent in both Germany and France and nearly reaching fifty percent in Britain. To pay for purchases in the United States Britain cashed in its extensive investments in American railroads and then began borrowing heavily on Wall Street. President Wilson was on the verge of cutting off the loans in late 1916 but allowed a great increase in U.S. government lending to the Allies. After 1919 the U.S. demanded repayment of these loans which in part were funded by German reparations which in turn were supported by American loans to Germany. This circular system collapsed in 1931 and the loans were never repaid. In 1934 Britain owed the US $4.4 billion257 of World War I debt.258 "The Girl Behind the Gun" - women workers 1915 Macro- and micro-economic consequences devolved from the war. Families were altered by the departure of many men. With the death or absence of the primary wage earner women were forced into the workforce in unprecedented numbers. At the same time industry needed to replace the lost labourers sent to war. This aided the struggle for voting rights for women. In Britain rationing was finally imposed in early 1918 limited to meat sugar and fats (butter and oleo) but not bread. The new system worked smoothly. From 1914 to 1918 trade union membership doubled from a little over four million to a little over eight million. Work stoppages and strikes became frequent in 19171918 as the unions expressed grievances regarding prices alcohol control pay disputes fatigue from overtime and working on Sundays and inadequate housing. Britain turned to her colonies for help in obtaining essential war materials whose supply had become difficult from traditional sources. Geologists such as Albert Ernest Kitson were called upon to find new resources of precious minerals in the African colonies. Kitson discovered important new deposits of manganese used in munitions production in the Gold Coast.259 Article 231 of the Treaty of Versailles (the so-called "war guilt" clause) declared Germany and its allies responsible for all "loss and damage" suffered by the Allies during the war and provided the basis for reparations. The total reparations demanded was 132 billion gold marks which was far more than the total German gold or foreign exchange. The economic problems that the payments brought and German resentment at their imposition are usually cited as one of the more significant factors that led to the end of the Weimar Republic and the beginning of the dictatorship of Adolf Hitler. After Germanys defeat in World War II payment of the reparations was not resumed. There was however outstanding German debt that the Weimar Republic had used to pay the reparations. Germany finished paying off the reparations in October 2010.260 See also World War I portal Book: World War I Wikipedia Books are collections of articles that can be downloaded or ordered in print.
