The Purdue Memorial Union (PMU) is a student union building located on the Purdue University campus in West Lafayette, Indiana , USA. It opened in 1924 as a memorial to the Purdue students who had fought in World War I. The building includes several restaurants, lounges, and student organization offices, as well as a bowling alley and a hotel.
173-520: In the early 1900s, Purdue was in need of a place for students, staff, and visitors to gather in the Purdue community. The Class of 1912 began collecting funds to build a union for Purdue. Funds were collected until the start of World War I . Many men and women from Purdue had participated in the war, and some have died in it. It was decided that the union should be a memorial dedicated to those men and women. From then on, funds were collected to begin building
346-523: A Bosnian Serb named Gavrilo Princip assassinated Archduke Franz Ferdinand , heir to the Austro-Hungarian throne. Austria-Hungary held Serbia responsible, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France , who had an alliance . The United Kingdom entered after Germany invaded Belgium , whose neutrality it guaranteed, and
519-645: A blue-water navy was vital for global power projection; Tirpitz had his books translated into German, while Wilhelm made them required reading for his advisors and senior military personnel. However, it was also an emotional decision, driven by Wilhelm's simultaneous admiration for the Royal Navy and desire to surpass it. Bismarck thought that the British would not interfere in Europe, as long as its maritime supremacy remained secure, but his dismissal in 1890 led to
692-592: A grenade at the Archduke's car and injured two of his aides. The other assassins were also unsuccessful. An hour later, as Ferdinand was returning from visiting the injured officers in hospital, his car took a wrong turn into a street where Gavrilo Princip was standing. He fired two pistol shots, fatally wounding Ferdinand and his wife Sophie . According to historian Zbyněk Zeman , in Vienna "the event almost failed to make any impression whatsoever. On 28 and 29 June,
865-540: A guerrilla warfare campaign and only surrendered two weeks after the armistice took effect in Europe. Before the war, Germany had attempted to use Indian nationalism and pan-Islamism to its advantage, a policy continued post-1914 by instigating uprisings in India , while the Niedermayer–Hentig Expedition urged Afghanistan to join the war on the side of Central Powers. However, contrary to British fears of
1038-742: A German advance towards Hasselt and Diest , the Cavalry Division commanded by de Witte, was sent to guard the bridge over the river Gete at Halen. During an evening meeting, the Belgian general staff directed de Witte to fight a dismounted action in an attempt to nullify the German numerical advantage. From communication intercepts, the Belgian Headquarters discovered that the Germans were heading in force towards de Witte and sent
1211-630: A German proclamation claimed that 110 people had been shot, with a Belgian account claiming 211 dead. At Seilles, fifty people were killed and at Tamines 384 civilians were shot. Dutch civilians heard gunfire on the night of 23 August, from Visé over the border and in the morning 4,000 refugees crossed the frontier, describing killings and the abduction of 700 men and boys for forced labour in Germany. Ten hostages were taken from every street in Namur and in other places one from every house. At Dinant
1384-408: A change in policy and an Anglo-German naval arms race began. Despite the vast sums spent by Tirpitz, the launch of HMS Dreadnought in 1906 gave the British a technological advantage. Ultimately, the race diverted huge resources into creating a German navy large enough to antagonise Britain, but not defeat it; in 1911, Chancellor Theobald von Bethmann Hollweg acknowledged defeat, leading to
1557-556: A decisive victory. By 1898–1899, such a manoeuvre was intended swiftly to pass between Antwerp and Namur and threaten Paris from the north. Helmuth von Moltke the Younger succeeded Schlieffen in 1906 and was less certain that the French would conform to German assumptions. Moltke adapted the deployment and concentration plan to accommodate an attack in the centre or an enveloping attack from both flanks as variants, by adding divisions to
1730-613: A direct threat. The 1908–1909 Bosnian Crisis began when Austria annexed the former Ottoman territory of Bosnia and Herzegovina , which it had occupied since 1878. Timed to coincide with the Bulgarian Declaration of Independence from the Ottoman Empire, this unilateral action was denounced by the European powers, but accepted as there was no consensus on how to resolve the situation. Some historians see this as
1903-515: A foothold across the Yser at Tervaete. By the end of 23 October the Belgians had been driven back from the riverbank and next day the Germans had a bridgehead 5 km (3.1 mi) wide. The French 42nd Division was used to reinforce the Belgians who had fallen back to a railway embankment from Diksmuide to Nieuwpoort which was 3.3–6.6 ft (1–2 m) above sea level. By 26 October the position of

#17327808516012076-418: A gap between the German armies as they closed on Paris. The French army, reinforced by the British expeditionary corps, seized this opportunity to counter-attack and pushed the German army 40 to 80 km back. Both armies were then so exhausted that no decisive move could be implemented, so they settled in trenches, with the vain hope of breaking through as soon as they could build local superiority. In 1911,
2249-479: A group of reserve divisions on each flank, a military force of c. 2,000,000 men. The armies were to concentrate opposite the German frontier around Épinal, Nancy and Verdun–Mezières, with an army in reserve around Ste. Ménéhould and Commercy. Since 1871, railway building had given the French General Staff sixteen lines to the German frontier, against thirteen available to the German army and
2422-435: A matter of British diplomatic and military advantage, rather than as an end in itself. The Agadir Crisis (1911) left the Belgian government in little doubt as to the risk of a European war and an invasion of Belgium by Germany. In September 1911, a government meeting concluded that Belgium must be prepared to resist a German invasion, to avoid accusations of collusion by the British and French governments. Britain, France and
2595-463: A particular threat. Belgian defences were to be based on a National Redoubt at Antwerp, with the field army massed in the centre of the country 60 km (37 mi) from the frontier, ready to manoeuvre to delay an invasion, while the frontiers were protected by the fortified regions of Liège and Namur. The German invasion of Belgium on 4 August 1914, in violation of Article VII of the Treaty of London
2768-548: A possibility. This was accentuated by British and Russian support for France against Germany during the 1911 Agadir Crisis . German economic and industrial strength continued to expand rapidly post-1871. Backed by Wilhelm II, Admiral Alfred von Tirpitz sought to use this growth to build an Imperial German Navy , that could compete with the British Royal Navy . This policy was based on the work of US naval author Alfred Thayer Mahan , who argued that possession of
2941-596: A retreat, which prevented the German army from enveloping and destroying the French. After another defensive action in the Battle of St. Quentin, the French were pushed to within miles of Paris. The British attempted to hold the line of the Mons–Condé Canal on the left flank of the French Fifth army against the German 1st Army and inflicted disproportionate casualties, before retreating when some units were overrun and
3114-834: A revolt in India, the outbreak of the war saw a reduction in nationalist activity. Leaders from the Indian National Congress and other groups believed support for the British war effort would hasten Indian Home Rule , a promise allegedly made explicit in 1917 by Edwin Montagu , the Secretary of State for India . In 1914, the British Indian Army was larger than the British Army itself, and between 1914 and 1918 an estimated 1.3 million Indian soldiers and labourers served in Europe, Africa, and
3287-516: A significant escalation, ending any chance of Austria cooperating with Russia in the Balkans, while also damaging diplomatic relations between Serbia and Italy. Tensions increased after the 1911–1912 Italo-Turkish War demonstrated Ottoman weakness and led to the formation of the Balkan League , an alliance of Serbia, Bulgaria, Montenegro , and Greece . The League quickly overran most of
3460-681: A squadron of the Royal Naval Air Service (RNAS) flew to Ostend, to conduct air reconnaissance between Bruges, Ghent and Ypres. Royal Marines landed in France on 19–20 September and began scouting unoccupied Belgium in motor cars; an RNAS Armoured Car Section was created by fitting vehicles with bulletproof steel. On 2 October, the Marine Brigade of the Royal Naval Division was moved to Antwerp, followed by
3633-451: A squadron of the Royal Naval Air Service (RNAS) had flown to Ostend, for air reconnaissance sorties between Bruges, Ghent, and Ypres. British marines landed at Dunkirk on the night of 19/20 September and on 28 September a battalion occupied Lille. The rest of the brigade occupied Cassel on 30 September and scouted the country in motor cars; an RNAS Armoured Car Section was created, by fitting vehicles with bullet-proof steel. On 2 October,

#17327808516013806-470: A strategy of military independence, based on a rearmament programme begun in 1909, which was expected to be complete in 1926. The Belgian plan was to have three army corps, to reduce the numerical advantage of the German armies over the French, intended to deter a German invasion. Conscription was introduced in 1909 but with a reduction in the term of service to fifteen months; the Agadir Crisis made
3979-818: A third zone under the German Navy along the coastline. The German occupation lasted until late 1918. The neutrality of Belgium had been established by the European Great Powers in the London Conference of 1830 . The Treaty of London (1839) recognized Belgian independence and neutrality from the United Kingdom of the Netherlands after the Belgian revolution . Until 1911, Belgian strategic analysis anticipated that if war came,
4152-478: A war on two fronts; the Schlieffen Plan envisaged using 80% of the army to defeat France, then switching to Russia. Since this required them to move quickly, mobilization orders were issued that afternoon. Once the German ultimatum to Russia expired on the morning of 1 August, the two countries were at war. At a meeting on 29 July, the British cabinet had narrowly decided its obligations to Belgium under
4325-402: A weak Ottoman government, rather than an ambitious Slav power like Bulgaria . Russia had ambitions in northeastern Anatolia while its clients had overlapping claims in the Balkans. These competing interests divided Russian policy-makers and added to regional instability. Austrian statesmen viewed the Balkans as essential for the continued existence of their Empire and saw Serbian expansion as
4498-455: A whole, the Somme offensive led to an estimated 420,000 British casualties, along with 200,000 French and 500,000 Germans. The diseases that emerged in the trenches were a major killer on both sides. The living conditions led to disease and infection, such as trench foot , lice , typhus , trench fever , and the ' Spanish flu '. At the start of the war, German cruisers were scattered across
4671-508: Is known, however, that from 1908 to 1913, military spending by the six major European powers increased by over 50% in real terms. The years before 1914 were marked by a series of crises in the Balkans, as other powers sought to benefit from the Ottoman decline. While Pan-Slavic and Orthodox Russia considered itself the protector of Serbia and other Slav states, they preferred the strategically vital Bosporus straits to be controlled by
4844-574: The Schutzkorps was established, and carried out the persecution of Serbs. The assassination initiated the July Crisis, a month of diplomatic manoeuvring between Austria-Hungary, Germany, Russia, France and Britain. Believing that Serbian intelligence helped organise Franz Ferdinand's murder, Austrian officials wanted to use the opportunity to end their interference in Bosnia and saw war as
5017-641: The World War . In August 1914, the magazine The Independent wrote "This is the Great War. It names itself". In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War." Contemporary Europeans also referred to it as " the war to end war " and it was also described as "the war to end all wars" due to their perception of its unparalleled scale, devastation, and loss of life. The first recorded use of
5190-517: The Asia-Pacific , and in Europe was characterised by trench warfare ; the widespread use of artillery , machine guns, and chemical weapons (gas); and the introductions of tanks and aircraft . World War I was one of the deadliest conflicts in history , resulting in an estimated 10 million military dead and more than 20 million wounded , plus some 10 million civilian dead from causes including genocide . The movement of large numbers of people
5363-695: The Australian Naval and Military Expeditionary Force landed on the island of New Britain , then part of German New Guinea . On 28 October, the German cruiser SMS Emden sank the Russian cruiser Zhemchug in the Battle of Penang .

5536-479: The Belgian government had announced that if war came it would uphold its neutrality . The Belgian government mobilised its armed forces on 31 July and a state of heightened alert ( Kriegsgefahr ) was proclaimed in Germany . On 2 August, the German government sent an ultimatum to Belgium , demanding passage through the country and German forces invaded Luxembourg . Two days later, the Belgian government refused
5709-721: The Rüstungswende or 'armaments turning point', when he switched expenditure from the navy to the army. This decision was not driven by a reduction in political tensions but by German concern over Russia's quick recovery from its defeat in the Russo-Japanese War and subsequent 1905 Russian Revolution . Economic reforms led to a significant post-1908 expansion of railways and transportation infrastructure, particularly in its western border regions. Since Germany and Austria-Hungary relied on faster mobilisation to compensate for their numerical inferiority compared to Russia,
5882-828: The United States entered the war on the Allied side following Germany's resumption of unrestricted submarine warfare against Atlantic shipping. Later that year, the Bolsheviks seized power in the Russian October Revolution , and Soviet Russia signed an armistice with the Central Powers in December, followed by a separate peace in March 1918. That month, Germany launched an offensive in
6055-487: The hydrophone and depth charges were introduced, destroyers could potentially successfully attack a submerged submarine. Convoys slowed the flow of supplies since ships had to wait as convoys were assembled; the solution was an extensive program of building new freighters. Troopships were too fast for the submarines and did not travel the North Atlantic in convoys. The U-boats sunk more than 5,000 Allied ships, at
6228-766: The tank . After the First Battle of the Marne in September 1914, Allied and German forces unsuccessfully tried to outflank each other, a series of manoeuvres later known as the " Race to the Sea ". By the end of 1914, the opposing forces confronted each other along an uninterrupted line of entrenched positions from the Channel to the Swiss border. Since the Germans were normally able to choose where to stand, they generally held
6401-588: The 1839 Treaty of London did not require it to oppose a German invasion with military force; however, Prime Minister Asquith and his senior Cabinet ministers were already committed to supporting France, the Royal Navy had been mobilised, and public opinion was strongly in favour of intervention. On 31 July, Britain sent notes to Germany and France, asking them to respect Belgian neutrality; France pledged to do so, but Germany did not reply. Aware of German plans to attack through Belgium, French Commander-in-Chief Joseph Joffre asked his government for permission to cross
6574-563: The 1879 Dual Alliance , which became the Triple Alliance when Italy joined in 1882. For Bismarck, the purpose of these agreements was to isolate France by ensuring the three Empires resolve any disputes between themselves. In 1887, Bismarck set up the Reinsurance Treaty , a secret agreement between Germany and Russia to remain neutral if either were attacked by France or Austria-Hungary. For Bismarck, peace with Russia
6747-441: The 1913 Treaty of London , which had created an independent Albania while enlarging the territories of Bulgaria, Serbia, Montenegro and Greece. However, disputes between the victors sparked the 33-day Second Balkan War , when Bulgaria attacked Serbia and Greece on 16 June 1913; it was defeated, losing most of Macedonia to Serbia and Greece, and Southern Dobruja to Romania. The result was that even countries which benefited from
6920-470: The 4th Infantry Brigade to reinforce the Cavalry Division. The battle began around 8:00 a.m. when a German scouting party, advancing from Herk-de-Stad , was engaged with small-arms fire by Belgian troops. About 200 Belgian soldiers attempted to set up a fortified position in the old brewery in Halen but were driven out of the building when the Germans brought up field artillery. Belgian engineers had blown
7093-722: The Admiralty sent a Warning Telegram to the Fleets and the War Office ordered the Precautionary Period . On 30 July the British government rejected German proposals for British neutrality and next day the Austro-Hungarian and Russian governments ordered full mobilisation. At midnight on 31 July/1 August the German government sent an ultimatum to Russia and announced a state of "Kriegsgefahr" during

7266-508: The Aisne and transport troops of the 6th Army northwards. On 29 August the Germans began bombarding the forts around Maubeuge. On 5 September, four of the forts were stormed by German infantry, creating a gap in the defences. On 7 September the garrison surrendered. The Germans took 40,000 prisoners and captured 377 guns. After the capture of Maubeuge the line from Cologne–Paris line was of limited use between Diedenhofen and Luxembourg, until
7439-821: The Austrian Archduke Franz Ferdinand was assassinated and on 5 July the Kaiser promised "the full support of Germany" if Austria-Hungary took action against Serbia. On 23 July the Austro-Hungarian Government sent an ultimatum to Serbia and next day the British Foreign Minister Sir Edward Grey proposed a conference to avert a war and the Belgian Government issued a declaration that Belgium would defend its neutrality "whatever
7612-569: The Austrians and Serbs clashed at the battles of the Cer and Kolubara ; over the next two weeks, Austrian attacks were repulsed with heavy losses. As a result, Austria had to keep sizeable forces on the Serbian front, weakening their efforts against Russia. Serbia's victory against Austria-Hungary in the 1914 invasion has been called one of the major upset victories of the twentieth century. In 1915,
7785-593: The Austrians briefly occupied the Serbian capital, Belgrade . A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first 10 months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats scored a coup by persuading Bulgaria to join the attack on Serbia. The Austro-Hungarian provinces of Slovenia , Croatia and Bosnia provided troops for Austria-Hungary. Montenegro allied itself with Serbia. Bulgaria declared war on Serbia on 14 October 1915 and joined in
7958-553: The Balkan Wars, such as Serbia and Greece, felt cheated of their "rightful gains", while for Austria it demonstrated the apparent indifference with which other powers viewed their concerns, including Germany. This complex mix of resentment, nationalism and insecurity helps explain why the pre-1914 Balkans became known as the " powder keg of Europe ". On 28 June 1914, Archduke Franz Ferdinand of Austria , heir presumptive to Emperor Franz Joseph I of Austria , visited Sarajevo ,
8131-428: The Belgian army had deteriorated to the point that another withdrawal was contemplated. King Albert rejected withdrawal and next day sluice gates at Nieuwpoort were opened to begin the flooding of the coastal plain. A German attack on 30 October crossed the embankment at Ramscappelle but was forced back during a counter-attack late on 31 October and on 2 November Diksmuide was captured.

The Belgian army fought the defensive Battle of the Yser (16–31 October) from Nieuwpoort (Nieuport) south to Diksmuide (Dixmude), as the German 4th Army attacked westwards and French, British, and some Belgian troops fought the First Battle of Ypres (19 October – 22 November) against the German 4th and 6th Armies. By November 1914, most of Belgium
8477-479: The Belgian coast. The German occupation authorities ruled Belgium under the pre-war Belgian administrative system, overseen by a small group of German officers and officials. The Germans had used Belgium to invade northern France, which had led to the Franco-British defeats of Charleroi and Mons, followed by a rapid retreat to the Marne, where the German advance was stopped. Attempts by both sides to envelop
8650-453: The Belgians to perceive that the British attitude to Belgium had changed and that it was now seen as a protectorate. A Belgian General Staff was formed in 1910 but the Chef d'État-Major Général de l'Armée , Lieutenant-Général Harry Jungbluth was retired on 30 June 1912 and not replaced until May 1914 by Lieutenant-General Chevalier Antonin de Selliers de Moranville . Moranville began planning for
8823-402: The British government ordered general mobilisation and Italy declared neutrality. On 4 August the British government sent an ultimatum to Germany and declared war on Germany at midnight on 4/5 August Central European Time. Belgium severed diplomatic relations with Germany and Germany declared war on Belgium. German troops crossed the Belgian frontier and attacked Liège. The Battle of Liège was

The Macedonian front was at first mostly static. French and Serbian forces retook limited areas of Macedonia by recapturing Bitola on 19 November 1916 following the costly Monastir offensive , which brought stabilisation of

After Vienna refused to withdraw its cruiser SMS Kaiserin Elisabeth from Tsingtao, Japan declared war on Austria-Hungary, and the ship was sunk in November 1914. Within a few months, Allied forces had seized all German territories in the Pacific, leaving only isolated commerce raiders and a few holdouts in New Guinea. Some of the first clashes of
9342-539: The First Battle of Flanders) began on 19 October with attacks by the German 6th and 4th armies at the same time that the BEF attacked towards Menin and Roulers. On 21 October, attacks by the 4th Army reserve corps were repulsed in a costly battle and on 23–24 October German attacks were conducted to the north, on the Yser by the 4th Army and to the south by the 6th Army. French attacks by the new Eighth Army were made towards Roulers and Thourout, which diverted German troops from British and Belgian positions. A new German attack
9515-409: The Franco-British and German armies to envelop the northern flank of the opposing army through Picardy , Artois and Flanders , rather than an attempt to advance northwards to the sea. Troops were moved from the French-German border by both sides, to the western flank to prevent opposing outflanking moves and then to counter-outflank the opponent. At the battles of Picardy and Albert in late September,
9688-453: The French Fifth Army on the right flank withdrew in the aftermath of the battle further east at Charleroi. Both sides had tactical success at Mons, the British had withstood the German First Army for 48 hours, prevented the French Fifth Army from being outflanked and then retired in good order. For the Germans the battle had been a tactical defeat and a strategic success. The First Army had been delayed and suffered many casualties but had forced
9861-433: The French Second and German 6th armies fought meeting engagements from the Oise north to the Somme but neither was able to envelop the northern flank of the opponent. French and German armies were moved from the east for further outflanking attempts to the north and the BEF made a camouflaged move from the Aisne front on the night of 1/2 October , with no movement by day, which with rainy weather grounding aircraft, deceived
10034-409: The French and Russians modernised their fortifications on the frontiers with Germany. Alfred von Schlieffen , Chief of the Imperial German General Staff ( Oberste Heeresleitung , OHL, the German army high command) from 1891 to 1906, devised a plan to evade the French frontier fortifications with an offensive on the northern flank, which would have a local numerical superiority and obtain rapidly
10207-425: The French and the BEF by keeping German troops in Belgium. German troop withdrawals to reinforce the main armies in France were postponed to repulse a Belgian sortie from 9 to 13 September and a German corps in transit was retained in Belgium for several days. Belgian resistance and German fear of francs-tireurs , led the Germans to implement a policy of terror ( schrecklichkeit ) against Belgian civilians soon after
10380-408: The French could afford to wait until German intentions were clear. The French deployment was intended to be ready for a German offensive in Lorraine or through Belgium. It was anticipated that the Germans would use reserve troops but also expected that a large German army would be mobilised on the border with Russia, leaving the western army with sufficient troops only to advance through Belgium south of
10553-462: The French fell back on 22 August and blew the bridge; German troops repairing the crossing were ostensibly obstructed by civilians, which was allegedly witnessed by General Max von Hausen , the 3rd Army commander. Hundreds of hostages were taken and lined up in the town square that evening and shot, 612 men, women and children being killed, after which the town centre was looted and burned. Horne and Kramer calculated that 670 civilians were killed in
SECTION 60
#173278085160110726-548: The German High Seas Fleet was confined to port. German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany changed its rules of engagement. After the 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
10899-465: The German Army increased in size from 1908 to 1914, he changed the allocation of forces between the two wings to 70:30. He also considered Dutch neutrality essential for German trade and cancelled the incursion into the Netherlands, which meant any delays in Belgium threatened the viability of the plan. Historian Richard Holmes argues that these changes meant the right wing was not strong enough to achieve decisive success. The initial German advance in
11072-457: The German Fourth Army lost 52,000 and the Sixth Army lost 28,000 casualties. After the defeat of the Imperial forces of Napoleon III in the Franco-Prussian War (1870–1871), c. 58,000 irregular troops known as francs tireurs (free shooters) were established by the French Government of National Defence , which killed c. 1,000 German troops and diverted c. 120,000 troops from field operations to guard
11245-428: The German advance for several days longer than the Germans had anticipated, which allowed Belgium and France more time to mobilise. The Belgian army had c. 15,000 casualties of whom c. 10,000 were from the 4th Division, which was moved to Le Havre and then by sea to Ostend on 27 August, from where it re-joined the field army at Antwerp . Der Weltkrieg , the German official history recorded
11418-452: The German demands and the British government guaranteed military support to Belgium. The German government declared war on Belgium on 4 August; German troops crossed the border and began the Battle of Liège . German military operations in Belgium were intended to bring the 1st, 2nd and 3rd Armies into positions in Belgium from which they could invade France, which, after the fall of Liège on 7 August, led to sieges of Belgian fortresses along
11591-400: The German right wing to squeeze through, a small bump in the road for the Germans, who had mobilised in two weeks and were ready to invade France by 20 August. The Battle of Halen (Haelen) was fought by mounted and dismounted cavalry and other forces on 12 August 1914 between German forces, led by Georg von der Marwitz and Belgian forces, led by Lieutenant-General Léon de Witte . To block
11764-462: The German right wing would sweep through the Netherlands and Belgium , then swing south, encircling Paris and trapping the French army against the Swiss border. The plan's creator, Alfred von Schlieffen , head of the German General Staff from 1891 to 1906, estimated that this would take six weeks, after which the German army would transfer to the East and defeat the Russians. The plan was substantially modified by his successor, Helmuth von Moltke
11937-405: The German super-heavy artillery, brought from the sieges in Belgium. Maubeuge was defended by fourteen forts, with a garrison of 30,000 French Territorials, and c. 10,000 French, British, and Belgian stragglers, and blocked the main Cologne–Paris rail line. Only the line from Trier to Liege, Brussels, Valenciennes, and Cambrai was open and had to carry supplies southward to the armies on
12110-426: The Germans bled heavily as well, with anywhere from 700,000 to 975,000 casualties between the two combatants. Verdun became a symbol of French determination and self-sacrifice. The Battle of the Somme was an Anglo-French offensive from July to November 1916. The opening day on 1 July 1916 was the bloodiest single day in the history of the British Army , which suffered 57,500 casualties, including 19,200 dead. As
12283-416: The Germans would attack France across the Franco-German border and trap the French armies against the Belgian frontier, as they had done in 1870. British and French guarantees of Belgian independence were made before 1914 but the possibility of landings in Antwerp was floated by the British military attaché in 1906 and 1911, which led the Belgians to suspect that the British had come to see Belgian neutrality as
12456-598: The Germans. On 8–9 October the BEF began to assemble around Abbeville, ready to begin an offensive around the German northern flank, towards the Belgian and Allied troops in Flanders. French and German efforts to outflank each other were frustrated, during the Battle of Arras in early October and the battles of La Bassée , Armentières and Messines . The "race" ended on the North Sea coast of Belgium around 19 October, when
12629-641: The Great Hall of the Union. This is the memorial for Purdue men and women that have fought in the wars. A scale model of Purdue is located in the Great Hall of the Union. The second floor of the PMU contains many lounges and private offices. The first part of the Union Club Hotel was built in 1929. Since then, it has grown into a full-service hotel.

From 6–7 October, the 7th Division and the 3rd Cavalry Division landed at Zeebrugge. Naval forces collected at Dover were formed into a separate unit, which became the Dover Patrol , to operate in the Channel and off the French-Belgian coast. The Race to
12975-463: The Menin road on 29 October and drove back the British cavalry next day, from Zandvoorde and Hollebeke to a line 3 km (1.9 mi) from Ypres. Three French battalions released from the Yser front by the inundation of the ground around the Yser, were sent south and on 31 October the British defence of Gheluvelt began to collapse, until a battalion counter-attacked and drove back the German troops from
13148-457: The Meuse and Sambre rivers. French intelligence had obtained a 1905 map exercise of the German general staff, in which German troops had gone no further north than Namur and assumed that plans to besiege Belgian forts were a defensive measure against the Belgian army. A German attack from south-eastern Belgium towards Mézières and a possible offensive from Lorraine towards Verdun, Nancy and St. Dié
13321-688: The Middle East. In all, 140,000 soldiers served on the Western Front and nearly 700,000 in the Middle East, with 47,746 killed and 65,126 wounded. The suffering engendered by the war, as well as the failure of the British government to grant self-government to India afterward, bred disillusionment, resulting in the campaign for full independence led by Mahatma Gandhi . Pre-war military tactics that had emphasised open warfare and individual riflemen proved obsolete when confronted with conditions prevailing in 1914. Technological advances allowed
13494-608: The Military Governor. Goltz was succeeded by General Moritz von Bissing on 27 November 1914. Soon after Bissing's appointment, OHL divided Belgium into three zones. The largest of the zones was the General Governorate of Brussels and the hinterland, the second zone came under the 4th Army and included Ghent and Antwerp; the third zone, under the Kaiserliche Marine (German Navy), covered
13667-478: The Netherlands were also to continue to be treated as potential enemies. In 1913 and 1914, the Germans made inquiries to the Belgian military attaché in Berlin, about the passage of German military forces through Belgium. If invaded, Belgium would need foreign help but would not treat foreign powers as allies or form objectives beyond the maintenance of Belgian independence. Neutrality forced the Belgian government into
13840-784: The Ottomans joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France, then to transfer its forces to the east, but its advance was halted in September , and by the end of the year the Western Front consisted of a continuous line of trenches stretching from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy , Bulgaria , Romania , Greece and others joined in from 1915 onward. In April 1917,
14013-613: The Ottomans' territory in the Balkans during the 1912–1913 First Balkan War , much to the surprise of outside observers. The Serbian capture of ports on the Adriatic resulted in partial Austrian mobilisation, starting on 21 November 1912, including units along the Russian border in Galicia . The Russian government decided not to mobilise in response, unprepared to precipitate a war. The Great Powers sought to re-assert control through
14186-449: The PMU. The PMU was opened in 1924 before it was completely finished in 1929. In the basement, a bowling alley was built in 1936. The ground floor contains most of the Union’s restaurants and coffee shops. On the main floor of the Union, there are student services as well as some lounges. There are two ballrooms where large groups can gather for special events. Located on this floor as well is
14359-613: The Russian Stavka agreed with the French to attack Germany within fifteen days of mobilisation, ten days before the Germans had anticipated, although it meant the two Russian armies that entered East Prussia on 17 August did so without many of their support elements. By the end of 1914, German troops held strong defensive positions inside France, controlled the bulk of France's domestic coalfields, and inflicted 230,000 more casualties than it lost itself. However, communications problems and questionable command decisions cost Germany
14532-457: The Russians from eastern Germany with offensives in Galicia , while France was being crushed. Divisions from the German army in the west ( Westheer ) would be moved eastwards to deal with the Russians as soon as a breathing-space was gained against the French. Under Plan XVII the French peacetime army was to form five field armies, with a group of reserve divisions attached to each army and
14705-459: The Sea took place from about 17 September – 19 October 1914, after the Battle of the Frontiers (7 August–13 September) and the German advance into France , which had been stopped at the First Battle of the Marne (5–12 September) and was followed by the First Battle of the Aisne (13 September – 28 September), a Franco-British counter-offensive. The term described reciprocal attempts by
14878-538: The Serbian retreat toward the Adriatic coast in the Battle of Mojkovac on 6–7 January 1916, but ultimately the Austrians also conquered Montenegro. The surviving Serbian soldiers were evacuated to Greece. After the conquest, Serbia was divided between Austro-Hungary and Bulgaria. In late 1915, a Franco-British force landed at Salonica in Greece to offer assistance and to pressure its government to declare war against
15051-417: The Treaty of London. The Germans suffered casualties of 150 dead, 600 wounded, 200–300 prisoners and c. 400 horses. Belgian casualties were 160 dead and 320 wounded. Namur was defended by a ring of modern fortresses, known as the fortified position of Namur ( position fortifiée de Namur ) and guarded by the Belgian 4th Division. When the siege began on 20 August, the Germans reversed
15224-651: The West was very successful. By the end of August, the Allied left, which included the British Expeditionary Force (BEF), was in full retreat , and the French offensive in Alsace-Lorraine was a disastrous failure, with casualties exceeding 260,000. German planning provided broad strategic instructions while allowing army commanders considerable freedom in carrying them out at the front, but von Kluck used this freedom to disobey orders, opening
15397-430: The Younger . Under Schlieffen, 85% of German forces in the west were assigned to the right wing, with the remainder holding along the frontier. By keeping his left-wing deliberately weak, he hoped to lure the French into an offensive into the "lost provinces" of Alsace-Lorraine , which was the strategy envisaged by their Plan XVII . However, Moltke grew concerned that the French might push too hard on his left flank and as
15570-459: The active members little better. Zuber wrote that as no records exist, there is no evidence that the Garde Civique was trained, had officers or a chain of command and that it was a guerilla army at best. Zuber wrote that on 18 August, the Belgian government disbanded the Garde Civique but Horne and Kramer had failed to explain the disposal of 146,000 firearms and claimed that none of
15743-446: The aggressor, German Chancellor Bethmann Hollweg delayed the commencement of war preparations until 31 July. That afternoon, the Russian government were handed a note requiring them to "cease all war measures against Germany and Austria-Hungary" within 12 hours. A further German demand for neutrality was refused by the French who ordered general mobilization but delayed declaring war. The German General Staff had long assumed they faced
15916-540: The arrival of the Royal Naval Division beginning on 3 October the Germans penetrated the outer ring of forts. The German advance began to compress a corridor from the west of the city along the Dutch border to the coast. The Belgians at Antwerp had used the strip to maintain contact with the rest of unoccupied Belgium and the Belgian field army commenced a withdrawal westwards towards the coast. On 9 October,
16089-407: The attack by the Austro-Hungarian army under Mackensen's army of 250,000 that was already underway. Serbia was conquered in a little more than a month, as the Central Powers, now including Bulgaria, sent in 600,000 troops in total. The Serbian army, fighting on two fronts and facing certain defeat, retreated into northern Albania . The Serbs suffered defeat in the Battle of Kosovo . Montenegro covered
16262-758: The attacks by the Tenth Army and the BEF to Lille was defeated in early October, more French troops were sent to the north and formed the Détachement d'Armée de Belgique ("Army Detachment of Belgium") under the command of General Victor d'Urbal . Falkenhayn assembled a new 4th Army from the III Reserve Corps, available since the fall of Antwerp and four new reserve corps, which had been raised in Germany in August and were deficient in training, weapons, equipment and leadership. The 4th Army offensive along
16435-412: The basement of the PMU. The PMU offers a variety of services to students, staff, and visitors as well. There are financial offices, student services, as well as many restaurants. The Purdue Student Union Board (PSUB) is a student organization that provides programs and services for students, staff, and the community of West Lafayette. PSUB was an organization before the union was built and it helped fund
16608-543: The best way of achieving this. However, the Foreign Ministry had no solid proof of Serbian involvement. On 23 July, Austria delivered an ultimatum to Serbia, listing ten demands made intentionally unacceptable to provide an excuse for starting hostilities. Serbia ordered general mobilization on 25 July, but accepted all the terms, except for those empowering Austrian representatives to suppress "subversive elements" inside Serbia, and take part in
16781-483: The border and pre-empt such a move. To avoid violating Belgian neutrality, he was told any advance could come only after a German invasion. Instead, the French cabinet ordered its Army to withdraw 10 km behind the German frontier, to avoid provoking war. On 2 August, Germany occupied Luxembourg and exchanged fire with French units when German patrols entered French territory; on 3 August, they declared war on France and demanded free passage across Belgium, which
16954-696: The bridge at Namur was repaired. The Battle of the Marne began as the Maubeuge forts were stormed; during the Battle of the Aisne, one of the VII Reserve Corps divisions arrived in time to join the German 7th Army, which closed a dangerous gap in the German line. While the BEF and the French armies conducted the Great Retreat into France (24 August – 28 September), small detachments of the Belgian, Frenchs and British armies conducted operations against German cavalry and Jägers . On 27 August,
17127-502: The bridge over the Gete but the structure only partly collapsed, which left the Germans an opportunity to send about 1,000 troops into the centre of Halen. The main Belgian defence line was to the west of Halen, on terrain which was partially overlooked by the Germans. The relatively easy capture of Halen made the Germans confident and led to several ill-conceived attempts to capture the Belgian position with sabre and lance attacks. Towards
17300-786: The building. In 1920 when the organization started it had only a few members, but it now has over a hundred. World War I World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War , was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers . Fighting took place mainly in Europe and the Middle East , as well as in parts of Africa and
17473-577: The bulk of the German armies in Belgium marched south into France , leaving small forces to garrison Brussels and the Belgian railways. The III Reserve Corps advanced to the fortified zone around Antwerp and a division of the IV Reserve Corps took over in Brussels. The Belgian field army made several sorties from Antwerp in late August and September to harass German communications and to assist
17646-537: The campaign saw the first use of anti-aircraft warfare after an Austrian plane was shot down with ground-to-air fire, as well as the first medical evacuation by the Serbian army. Upon mobilisation, in accordance with the Schlieffen Plan , 80% of the German Army was located on the Western Front, with the remainder acting as a screening force in the East. Rather than a direct attack across their shared frontier,
17819-649: The capital of the recently annexed Bosnia and Herzegovina . Cvjetko Popović , Gavrilo Princip , Nedeljko Čabrinović , Trifko Grabež , Vaso Čubrilović ( Bosnian Serbs ) and Muhamed Mehmedbašić (from the Bosniaks community), from the movement known as Young Bosnia , took up positions along the Archduke's motorcade route, to assassinate him. Supplied with arms by extremists within the Serbian Black Hand intelligence organisation, they hoped his death would free Bosnia from Austrian rule. Čabrinović threw
17992-466: The chance of a decisive outcome, while it had failed to achieve the primary objective of avoiding a long, two-front war. As was apparent to several German leaders, this amounted to a strategic defeat; shortly after the First Battle of the Marne , Crown Prince Wilhelm told an American reporter "We have lost the war. It will go on for a long time but lost it is already." On 30 August 1914, New Zealand occupied German Samoa (now Samoa ). On 11 September,
18165-504: The coast to St. Omer, began with operations against the Belgians, to drive them back from the Yser. On 16 October King Albert ordered that retreating soldiers were to be shot and officers who shirked would be court-martialled. The Belgian army was exhausted, water was so close to the land surface that trenches could only be dug 1–2 ft (0.30–0.61 m) deep and the field artillery was short of ammunition and had worn guns. A German offensive began on 18 October and by 22 October had gained
18338-420: The coast. Ostend and Zeebrugge were captured by the Germans unopposed. The troops from Antwerp advanced to positions along the Yser river and fought in the Battle of the Yser, which thwarted the final German attempt to turn the Allied northern flank. Belgian resistance and German fear of Francs-tireurs , led the Germans to implement a policy of schrecklichkeit (frightfulness) against Belgian civilians during
18511-523: The concentration of the army and met railway officials on 29 July. Belgian troops were to be massed in central Belgium, in front of the National Redoubt at Antwerp ready to face any border, while the fortified position of Liège and fortified position of Namur were left to secure the frontiers. On mobilisation, the King became Commander-in-Chief and chose where the army was to concentrate. Amid
18684-670: The consequences". On 25 July the Serbian Government ordered mobilisation and on 26 July, the Austro-Hungarian Government ordered partial mobilisation against Serbia. The French and Italian governments accepted British proposals for a conference on 27 July but the next day Austria-Hungary declared war on Serbia and the German government rejected the British proposal for a conference. On 29 July the Russian government ordered partial mobilisation against Austria-Hungary as hostilities commenced between Austria-Hungary and Serbia. The German government made proposals to secure British neutrality;
18857-520: The cost of 199 submarines. 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. Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses,
19030-522: The creation of new independent states, including Poland , Finland , the Baltic states , Czechoslovakia , and Yugoslavia . The League of Nations was established to maintain world peace, but its failure to manage instability during the interwar period contributed to the outbreak of World War II in 1939. Before World War II , the events of 1914–1918 were generally known as the Great War or simply
19203-449: The creation of strong defensive systems largely impervious to massed infantry advances, such as barbed wire , machine guns and above all far more powerful artillery , which dominated the battlefield and made crossing open ground extremely difficult. Both sides struggled to develop tactics for breaching entrenched positions without heavy casualties. In time, technology enabled the production of new offensive weapons, such as gas warfare and
19376-613: The crossing of the Mons–Condé Canal and begun to advance into France. At the fortified city of Antwerp, German troops besieged a garrison of Belgian fortress troops, the Belgian field army and the British Royal Naval Division. The city was ringed by forts, known as the National Redoubt and was invested to the south and east by German forces, which began a bombardment of the Belgian fortifications with heavy and super-heavy artillery on 28 September. The Belgian garrison had no hope of victory without relief and despite
19549-515: The crossroads. German attacks south of the Menin road took small areas but Messines ridge had been consolidated by the British garrison and was not captured. By 1 November, the BEF was close to exhaustion and 75 of 84 infantry battalions had fewer than 300 men left; 1 ⁄ 3 of their establishment. The French XIV Corps was moved north from the Tenth Army and the French IX Corps attacked southwards towards Becelaere, which relieved
19722-965: The crowds listened to music and drank wine, as if nothing had happened." Nevertheless, the impact of the murder of the heir to the throne was significant, and has been described by historian Christopher Clark as a "9/11 effect, a terrorist event charged with historic meaning, transforming the political chemistry in Vienna". Austro-Hungarian authorities encouraged subsequent anti-Serb riots in Sarajevo . Violent actions against ethnic Serbs were also organised outside Sarajevo, in other cities in Austro-Hungarian-controlled Bosnia and Herzegovina, Croatia and Slovenia. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. A further 460 Serbs were sentenced to death. A predominantly Bosniak special militia known as
19895-650: The day; the Ottoman government ordered mobilisation and the London Stock Exchange closed. On 1 August the British government ordered the mobilisation of the Navy, the German government ordered general mobilisation and declared war on Russia. Hostilities commenced on the Polish frontier, the French government ordered general mobilisation and next day the German government sent an ultimatum to Belgium demanding passage through Belgian territory, as German troops crossed
20068-407: The detachments of garrisons to guard lines of communication, the German army resorted to schrecklichkeit (frightfulness), quickly to terrorise civilians into submission. On some occasions, the atrocities were committed by front-line troops in the heat of the moment; other crimes were cold blooded, taking place days after the fighting had ended. Andenne , near Namur, was burnt down on 20 August and
20241-407: The disruption of the new rearmament plan the disorganised and poorly trained Belgian conscripts would benefit from a central position to delay contact with an invader. The army would also need fortifications for defence but these had been built on the frontier. Another school of thought wanted a return to a frontier deployment, in line with French theories of the offensive. The Belgian plan that emerged
20414-416: The early part of the siege and by the morning of 17 August, the German 1st, 2nd and 3rd armies were free to resume their advance to the French frontier, yet German troops only appeared in strength before Namur on 20 August. The Belgian field army withdrew from the Gete towards Antwerp from 18–20 August and Brussels was captured unopposed on 20 August. The siege of Liège had lasted for eleven days, rather than
20587-402: The end of the day the Germans were forced to retire towards their main columns east of Halen. The battle was a victory for the Belgian army but was strategically indecisive. The Germans went on to besiege the fortified cities of Namur , Liège and Antwerp , which had formed the basis of the Belgian defensive system, intended to delay an invader until foreign troops could intervene, according to
20760-695: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany. After the 1877–1878 Russo-Turkish War , the League was dissolved due to Austrian concerns over the expansion of Russian influence in the Balkans , an area they considered to be of vital strategic interest. Germany and Austria-Hungary then formed
20933-455: The failure of the October offensive and aimed to capture Ypres and Mt Kemmel but even this proved beyond the capacity of the 4th and 6th armies. On 10 November Falkenhayn told the Kaiser that no great success could be expected on the Western Front. German troops were tired and there was little heavy artillery ammunition left. The Westheer was ordered to dig in and defend its conquests, while
21106-400: The first time on the Western Front. Several types of gas soon became widely used by both sides and though it never proved a decisive, battle-winning weapon, it became one of the most feared and best-remembered horrors of the war. In February 1916, the Germans attacked French defensive positions at the Battle of Verdun , lasting until December 1916. Casualties were greater for the French, but
21279-473: The former Garde Civique fired them at German soldiers. Zuber quoted a folk tradition, which had it that a civilian killed a German officer at Bellefontaine and wrote that the Germans shot Belgian civilians in reprisal for franc tireur attacks and that " franc tireur attacks" had taken place, both being war crimes. Zuber also wrote that there were no German reprisals in the Flemish areas of Belgium or
21452-595: The front. Serbian and French troops finally made a breakthrough in September 1918 in the Vardar offensive , after most German and Austro-Hungarian troops had been withdrawn. The Bulgarians were defeated at the Battle of Dobro Pole , and by 25 September British and French troops had crossed the border into Bulgaria proper as the Bulgarian army collapsed. Bulgaria capitulated four days later, on 29 September 1918. The German high command responded by despatching troops to hold
21625-400: The frontier of Luxembourg. Military operations began on the French frontier, Libau was bombarded by a German cruiser SMS Augsburg and the British government guaranteed naval protection for French coasts. On 3 August the Belgian Government refused German demands and the British government guaranteed military support to Belgium should the German army invade. Germany declared war on France,
21798-542: The globe, some of which were subsequently used to attack Allied merchant shipping . These were systematically hunted down by the Royal Navy, though not before causing considerable damage. One of the most successful was the SMS ; Emden , part of the German East Asia Squadron stationed at Qingdao , which seized or sank 15 merchantmen, a Russian cruiser and a French destroyer. Most of the squadron
21971-419: The government continue its preparations but until 1913, the size of the army was not fixed as a proportion of the population. The annual conscription of 13,300 recruits was increased to 33,000 to accumulate the trained manpower for a field army of 180,000 men. Older men would continue to serve as garrison troops and by 1926 about 340,000 men would be available. Implementation of the new scheme had disrupted
22144-549: The high ground, while their trenches tended to be better built; those constructed by the French and English were initially considered "temporary", only needed until an offensive would destroy the German defences. Both sides tried to break the stalemate using scientific and technological advances. On 22 April 1915, at the Second Battle of Ypres , the Germans (violating the Hague Convention ) used chlorine gas for
22317-407: The interior of France, where no franc tireur attacks occurred. The offensive strategies of France and Germany had failed by November 1914, leaving most of Belgium under German occupation and Allied blockade. The German General Government of Belgium ( Kaiserliches Deutsches Generalgouvernement Belgien ), was established on 26 August 1914 with Field Marshal Colmar Freiherr von der Goltz as
22490-531: The invasion, in which massacres, executions, hostage-taking and the burning of towns and villages took place and became known as the Rape of Belgium . After the Battle of the Frontiers ended, the French armies in the north and the British Expeditionary Force (BEF) began the Great Retreat into France (24 August – 28 September) , the Belgian army and small detachments of French and British troops fought in Belgium against German cavalry and Jäger . On 27 August,
22663-580: The invasion. Massacres, executions, hostage taking, and the burning of towns and villages took place and became known as the Rape of Belgium . After the Battle of the Sambre, the French Fifth Army and the BEF retreated and on 25 August, General Fournier was ordered to defend the fortress, which was surrounded on 27 August by the VII Reserve Corps, which had two divisions and eventually received some of
22836-470: The investigation and trial of Serbians linked to the assassination. Claiming this amounted to rejection, Austria broke off diplomatic relations and ordered partial mobilisation the next day; on 28 July, they declared war on Serbia and began shelling Belgrade . Russia ordered general mobilization in support of Serbia on 30 July. Anxious to ensure backing from the SPD political opposition by presenting Russia as
23009-462: The last open area from Diksmuide to the North Sea was occupied by Belgian troops, who had been withdrawn from the siege of Antwerp (28 September – 10 October). The British held a line from La Bassée to Passchendaele, the French from Passchendaele to Diksmuide and the Belgian army from Diksmuide to Nieuwpoort. The outflanking attempts had resulted in a number of encounter battles but neither side
23182-528: The left (southern) flank opposite the French frontier, from the c. 1,700,000 men expected to be mobilised in the Westheer (Western Army). The main German force would still advance through Belgium and attack southwards into France, the French armies would be enveloped on the left and pressed back over the Meuse, Aisne, Somme, Oise, Marne, and Seine, by short, rapid attacks, unable to withdraw into central France. The French would either be annihilated or
23355-406: The line, but these forces were too weak to re-establish a front. German invasion of Belgium (1914) [REDACTED] Belgium [REDACTED] France [REDACTED] United Kingdom 1915 1916 1917 1918 Associated articles Associated articles The German invasion of Belgium was a military campaign which began on 4 August 1914. On 24 July,
23528-605: The lines of communication. The status of neutral countries was established by the Fifth Convention of the Hague Peace Conference (1907) and signed by Germany. The Belgian government did not forbid resistance, because belligerents were not allowed to move troops or supplies through neutral territory; Article 5 required neutrals to prevent such acts and Article 10 provided that resistance by a neutral could not be considered to be hostile. At Hervé during
23701-645: The maneuver from the north would create conditions for victory in the centre or in Lorraine, on the common border. A corollary to the emphasis on the Western Front was lack of troops for the Eastern Front against Russia. In the east the Germans planned a defensive strategy and relied on the 8th Army to defend East Prussia and on the Austro-Hungarian Army ( Landstreitkräfte Österreich-Ungarns / Császári és Királyi Hadsereg ) to divert
23874-573: The night of 4 August, firing broke out and a few days later a German reporter wrote that only nineteen of 500 houses were still standing. The speed by which allegations of franc tireur warfare reached Germany led to suspicions of orchestration, since newspapers reported atrocities against German soldiers as soon as 5 August; on 8 August, troops marching towards the German-Belgian frontier bought newspapers containing lurid details of Belgian civilians marauding, ambushing German troops, desecrating corpses and poisoning wells. To avoid delays and minimise
24047-409: The ocean, even to neutral ships. Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. The Battle of Jutland in May/June 1916 was the only full-scale clash of battleships during the war, and one of the largest in history. The clash was indecisive, though the Germans inflicted more damage than they received; thereafter the bulk of
24220-416: The old one but had not yet become effective by 1914. During the crisis over the assassination of Archduke Franz Ferdinand of Austria , regiments were divided and eight conscription classes were incorporated into the army to provide 117,000 men for the field army and 200,000 fortress troops. The Belgian army planned a defence based on interior lines , rather than concentrating the army on the border against
24393-404: The opponent's northern flank had then brought the main armies back to the north. Sieges and small operations were being conducted by detachments from the main German armies against Belgian, British and French troops. The siege of Antwerp ended as operations resumed on the western border, with the costly and indecisive battles of the Yser and Ypres. Falkenhayn attempted to gain a limited success after
24566-399: The pressure on both British flanks. German attacks began to diminish on 3 November, by when Armeegruppe von Fabeck had lost 17,250 casualties. A French offensive was planned for 6 November towards Langemarck and Messines, to widen the Ypres salient but German attacks began again on 5 November in the same area until 8 November, then again on 10–11 November. The main attack on 10 November
24739-414: The primary engagement in the German invasion of Belgium and the first battle of World War I. The attack on the city began on 5 August and lasted until 16 August, when the last fort was surrendered. The German invasion led the British to declare war and the length of the siege may have delayed the German invasion of France by 4–5 days. Railways needed by the German armies in eastern Belgium were closed during
24912-681: The protection of the " cruiser rules ", which demanded warning and movement of crews to "a place of safety" (a standard that lifeboats did not meet). Finally, in early 1917, Germany adopted a policy of unrestricted submarine warfare , realising the Americans would eventually enter the war. Germany sought to strangle Allied sea lanes before the United States could transport a large army overseas, but, after initial successes, eventually failed to do so. 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
25085-424: The province of West Flanders . In 2007, Terence Zuber called writing on German atrocities by Schmitz and Niewland (1924), Horne and Kramer (2001) and Zuckerman (2004) apologia and wrote that on 5 August, the Belgian government armed 100,000 civilians as "inactive Garde Civique ", who joined the 46,000 members of the active Garde Civique . Zuber called the inactive members untrained, non-uniformed and
25258-638: The remaining garrison surrendered, the Germans occupied the city, and some British and Belgian troops escaped north to the Netherlands, where they were interned for the duration of the war. A large amount of ammunition and many of the 2,500 guns at Antwerp were captured intact by the Germans. The c. 80,000 surviving men of the Belgian field army escaped westwards, with most of the Royal Naval Division. British casualties were 57 killed, 138 wounded, 1,479 interned and 936 taken prisoner. The operations to save Antwerp failed, but detained German troops when they were needed for operations against Ypres and
25431-413: The rest of the division on 6 October. From 6 to 7 October, the 7th Division and the 3rd Cavalry Division landed at Zeebrugge and naval forces collected at Dover were formed into the Dover Patrol , to operate in the Channel and off the French–Belgian coast. Despite minor British reinforcement, the siege of Antwerp ended when its defensive ring of forts was destroyed by German super-heavy artillery. The city
25604-421: The river Meuse at Namur and the surrender of the last forts (16–17 August). The government abandoned the capital, Brussels , on 17 August and after fighting on the Gete river, the Belgian field army withdrew westwards to the National Redoubt at Antwerp on 19 August. Brussels was occupied the following day and the siege of Namur began on 21 August. After the Battle of Mons and the Battle of Charleroi ,
25777-423: The southern flank of a German invasion through Belgium or southwards against the northern flank of an attack through Lorraine. No formal provision was made for combined operations with the British Expeditionary Force (BEF) but joint arrangements had been made and in 1911 during the Second Moroccan Crisis , the French had been told that six British divisions could be expected to operate around Maubeuge. On 28 June
25950-584: The surviving population of 10,000 people were expelled and over 2,000 buildings were burnt down. At the Catholic University of Leuven , the historic library of 300,000 medieval books and manuscripts was destroyed. Large amounts of strategic materials , foodstuffs and modern industrial equipment were looted and transferred to Germany. From 5 August to 21 October, German troops burned homes and killed civilians throughout eastern and central Belgium, including crimes at Aarschot (156 dead), Mechelen , Dendermonde and from Berneau in Liège Province to Esen in
26123-474: The tactics used at Liège, by waiting until the siege train arrived from Liège and bombarding the forts before attacking with infantry. French troops sent to relieve the city were defeated at the Battle of Charleroi and only a few managed to participate in the fighting for Namur. The forts were destroyed in the bombardment, much of the Belgian 4th Division withdrew to the south, and the Belgian fortress troops were forced to surrender on 24 August. The Belgians had held
26296-405: The taking of 6,700 Belgian and French prisoners and twelve field guns, and 900 German casualties, of whom c. 300 were killed. The Battle of Charleroi was fought on 21 August 1914, between French and German forces and was part of the Battle of the Frontiers. The French were planning an attack across the river Sambre, when the Germans attacked and the French Fifth army was forced into
26469-415: The term First World War was in September 1914 by German biologist and philosopher Ernst Haeckel who stated, "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." For much of the 19th century, the major European powers maintained a tenuous balance of power , known as the Concert of Europe . After 1848, this
26642-584: The threat posed by the closing of this gap was more important than competing with the Royal Navy. After Germany expanded its standing army by 170,000 troops in 1913, France extended compulsory military service from two to three years; similar measures were taken by the Balkan powers and Italy, which led to increased expenditure by the Ottomans and Austria-Hungary. Absolute figures are difficult to calculate due to differences in categorising expenditure since they often omit civilian infrastructure projects like railways which had logistical importance and military use. It
26815-518: The town. The 1st Army passed through Leuven (Louvain) on 19 August and was followed by the IX Reserve Corps. On 25 August, a Belgian sortie from Antwerp drove back German outposts and caused confusion behind the front line. A horse entered Leuven during the night and caused a stampede, which panicked German sentries, after which General von Luttwitz, the Military Governor of Brussels, ordered reprisals. Burning and shooting by German troops took place for five days, during which 248 residents were killed;
26988-426: The two days anticipated by the Germans. Belgian military operations in the east of the country had delayed German plans, which some writers claimed had been advantageous to the Franco-British forces in northern France and in Belgium. Wolfgang Förster wrote that the German timetable of deployment had required its armies to reach a line from Thionville to Sedan and Mons by the 22nd day of mobilisation (23 August), which
27161-429: The war ended with the Armistice of 11 November 1918 . The Paris Peace Conference of 1919–1920 imposed settlements on the defeated powers, most notably the Treaty of Versailles , by which Germany lost significant territories, was disarmed, and was required to pay large war reparations to the Allies. The dissolution of the Russian, German, Austro-Hungarian, and Ottoman Empires redrew national boundaries and resulted in
27334-413: The war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorates of Togoland and Kamerun . On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa , led by Colonel Paul von Lettow-Vorbeck , fought
27507-418: The west , which despite initial successes left the German Army exhausted and demoralised. A successful Allied counter-offensive from August 1918 caused a collapse of the German front line. By early November, Bulgaria, the Ottoman Empire and Austria-Hungary had each signed armistices with the Allies, leaving Germany isolated. Facing a revolution at home , Kaiser Wilhelm II abdicated on 9 November, and
27680-527: Was a compromise in which the field army concentrated behind the Gete river with two divisions forward at Liège and Namur. German strategy had given priority to offensive operations against France and a defensive posture against Russia since 1891. German planning was determined by numerical inferiority, the speed of mobilisation and concentration and the effect of the vast increase of the power of modern weapons. Frontal attacks were expected to be costly and protracted, leading to limited success, particularly after
27853-432: Was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when
28026-402: Was abandoned on 9 October and Allied forces withdrew to West Flanders . At the end of the Great Retreat, the Race to the Sea (17 September – 19 October) began, a period of reciprocal attempts by German and Franco-British forces to outflank each other, extending the front line northwards from the Aisne, into Picardy, Artois, and Flanders. Military operations in Belgium also moved westwards as
28199-434: Was able to gain a decisive victory . The Battle of the Yser took place in October 1914 along a 35 km (22 mi) long stretch of the Yser river and Yperlee canal in Belgium. On 15 October c. 50,000 Belgian troops ended their retreat from Antwerp and took post between Nieuwpoort and French Fusiliers Marins at Diksmuide, which marked the end of the "Race to the Sea". Both sides conducted offensives and when
28372-434: Was achieved ahead of schedule. In Bulletin Belge des Sciences Militaires , a four-day delay was claimed. John Buchan wrote that "The triumph was moral – an advertisement to the world that the ancient faiths of country and duty could still nerve the arm for battle, and that the German idol, for all its splendour, had feet of clay." In 2007, Foley called the neutralisation of the Belgian defences at Liège sufficient to enable
28545-417: Was anticipated; the plan was an evolution from Plan XVI and made more provision for the possibility of a German offensive from the north through Belgium. The First, Second and Third armies were to concentrate between Épinal and Verdun opposite Alsace and Lorraine, the Fifth Army was to assemble from Montmédy to Sedan and Mézières and the Fourth Army was to be held back west of Verdun, ready to move east to attack
28718-403: Was challenged by Britain's withdrawal into so-called splendid isolation , the decline of the Ottoman Empire , New Imperialism , and the rise of Prussia under Otto von Bismarck . Victory in the 1870–1871 Franco-Prussian War allowed Bismarck to consolidate a German Empire . Post-1871, the primary aim of French policy was to avenge this defeat, but by the early 1890s, this had switched to
28891-410: Was made by the 4th Army between Langemarck and Diksmuide, in which Diksmuide was lost by the Franco-Belgian garrison. Next day to the south, the British were subjected to an unprecedented bombardment between Messines and Polygon Wood and then an attack by Prussian Guard, which broke into British positions along the Menin road, before being forced back by counter-attacks. From mid-October to early November
29064-409: Was planned in which the 4th and 6th armies would pin Allied troops while a new formation, Armeegruppe von Fabeck with six new divisions and more than 250 heavy guns took over the boundary of the two German armies, to attack north-west between Messines and Gheluvelt. The British I Corps was dug in astride the Menin road, with dismounted British cavalry further south. German attacks took ground on
29237-654: Was refused. Early on the morning of 4 August, the Germans invaded, and Albert I of Belgium called for assistance under the Treaty of London . Britain sent Germany an ultimatum demanding they withdraw from Belgium; when this expired at midnight, without a response, the two empires were at war. Germany 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 those had never been tested in exercises. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia. Beginning on 12 August,
29410-600: Was returning to Germany when it sank two British armoured cruisers at the Battle of Coronel in November 1914, before being virtually destroyed at the Battle of the Falkland Islands in December. The SMS Dresden escaped with a few auxiliaries, but after the Battle of Más a Tierra , these too were either destroyed or interned. Soon after the outbreak of hostilities, Britain began a naval blockade of Germany . This proved effective in cutting off vital supplies, though it violated accepted international law. Britain also mined international waters which closed off entire sections of
29583-408: Was the casus belli , the reason given by the British government, for declaring war on Germany. Belgian military planning was based on the assumption that other powers would oust an invader but the likelihood of a German invasion did not lead to France and Britain being seen as allies or for the Belgian government to do more than protect its independence. The Anglo-French Entente (1904) had led
29756-586: Was the foundation of German foreign policy but in 1890, he was forced to retire by Wilhelm II . The latter was persuaded not to renew the Reinsurance Treaty by his new Chancellor , Leo von Caprivi . This gave France an opening to agree the Franco-Russian Alliance in 1894, which was then followed by the 1904 Entente Cordiale with Britain. The Triple Entente was completed by the 1907 Anglo-Russian Convention . While not formal alliances, by settling long-standing colonial disputes in Asia and Africa, British support for France or Russia in any future conflict became
29929-415: Was under German occupation and Allied naval blockade. A German military administration was established on 26 August 1914, to rule through the pre-war Belgian administrative system, overseen by a small group of German officers and officials. Belgium was divided into administrative zones, the General Government of Brussels and its hinterland; a second zone, under the 4th Army, including Ghent and Antwerp and
