138-727: On the basis of experience during World War I , the Admiralty instituted trade convoys in United Kingdom coastal waters from September 1939. Convoys gradually extended westward until HX 129 left Halifax, Nova Scotia on 27 May 1941 as the first convoy to receive escort for the entire trip from Canada. The American Neutrality Zone offered some protection in North American coastal waters until United States declaration of war in December 1941. The Royal Canadian Navy organized

276-523: 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

414-645: 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

552-592: 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,

690-540: 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

828-408: 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

966-469: A class largely neglected by the British. It was Renault 's excellent small tank design, the FT , incorporating a proper climbing face for the tracks, that was the first tank to incorporate a top-mounted turret with a full 360° traverse capability. The FT was in many respects the first truly 'modern' tank, having a layout that has been followed by almost all designs ever since: driver at the front; main armament in

1104-494: A crew of eight, four of whom were needed to handle the steering and drive gears. The tanks were capable of, at best, 6 km/h (3.7 mph), matching the speed of marching infantry with whom they were to be integrated to aid in the destruction of enemy machine guns. In practice, their speed on the broken ground could be as little as 1 mph. After the war the Royal Commission on Awards to Inventors decided that

1242-436: A culminating proposal in late 1917, accompanied by a huge one-eighth scale model, but all fell on substantially-deaf ears. De Mole's proposal already had the climbing face, which was so typical of the later World War I British tanks, but it is unknown whether there was some connection. Inquiries to the government of Australia after the war yielded polite responses that Mr. De Mole's ideas had unfortunately been too advanced for

1380-613: 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

1518-402: A fully rotating turret on top; engine at the rear. Previous models had been "box tanks", with a single crowded space combining the role of engine room, fighting compartment, ammunition stock and driver's cabin. (A very similar Peugeot prototype, with a fixed casemate mounting a short 75mm cannon, was trialed in 1918 but the idea was not pursued). The FT had the largest production run of any tank of

1656-471: 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,

1794-458: A letter from a friend, Hugh Marriott, a mining engineer, who drew his attention to a Holt caterpillar tractor that Marriott had seen in Belgium. Marriott thought that it might be useful for transport over difficult ground, and Swinton had passed the information on to the appropriate departments. Swinton then suggested the idea of an armoured tracked vehicle to the military authorities by sending

1932-434: A major proponent of tanks, declared, "Gentlemen, victory will belong in this war to the one of the two belligerents that will manage to be the first to succeed in putting a 75 mm cannon on a vehicle that can move on all types of terrain." Armored cars indeed proved useful in open land, such as in deserts, but were not very good at crossing obstacles, such as trenches and barriers, or in more-challenging terrain. The other issue

2070-534: A much bigger explosion. Engine power was a primary limitation on the tanks; the roughly one hundred horsepower engines gave a power-to-weight ratio of 3.3 hp/ton (2.5 kW/ton). By the end of the 20th century, power-to-weight ratios exceeded 20 hp/ton (15 kW/ton). Many feel that because the British Commander Field Marshal Douglas Haig was himself a horse cavalryman, his command failed to appreciate

2208-548: 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

2346-434: A pre-war motor engineer, added a larger track frame to the hull of "Little Willie". In order to achieve the demanded gap clearance a rhomboidal shape was chosen—stretching the form to improve the track footprint and climbing capacity. To keep a low centre of gravity the rotating turret design was dropped in favour of sponsons on the sides of the hull fitted with naval 6-pounder (57 mm) guns. A final specification

2484-584: A proposal to Lieutenant-Colonel Maurice Hankey , who tried to interest Lord Kitchener in the idea. When that failed, he sent a memorandum in December to the Committee of Imperial Defence , of which he was himself the secretary. Winston Churchill the First Lord of the Admiralty was one of the members of the committee. Hankey proposed to build a gigantic steel roller pushed by tracked tractors to shield

2622-532: A prototype. Lacking the requisite contacts, he let it drop. An approach to the German government was similarly fruitless. In 1912, Lancelot De Mole , of South Australia , submitted a proposal to the British War Office for a "chain-rail vehicle which could be easily steered and carry heavy loads over rough ground and trenches". De Mole made more proposals to the War Office in 1914 and 1916, with

2760-834: 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

2898-516: 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

3036-442: A trench-crossing supply vehicle, to produce a proof-of-concept vehicle with two tracks, based on a lengthened Bullock tractor chassis. Construction work began three weeks later. Fosters of Lincoln built the 14 ton " Little Willie ", which first ran on 8 September. Powered by a 105 hp (78 kW) Daimler engine, the 10-foot-high (3.0 m) armoured box was initially fitted with a low Bullock caterpillar. A rotating top turret

3174-490: A very short period of time, the first French tanks were poorly designed with respect to the need to cross trenches and did not take the sponson-mounting route of the British tanks. The first, the Char Schneider CA equipped with a short 75 mm howitzer, had poor mobility due to a short track length combined with a hull that overhung both front and rear. It was unreliable as well; a maximum of only about 130 of

3312-404: A walking pace at best. Their steel armour could stop small arms fire and fragments from high-explosive artillery shells. However, they were vulnerable to a direct hit from artillery and mortar shells. The environment inside was extremely unpleasant; as ventilation was inadequate the atmosphere was heavy with poisonous carbon monoxide from the engine and firing the weapons, fuel and oil vapours from

3450-478: 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

3588-402: 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

3726-455: 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

3864-508: 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

4002-574: 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

4140-641: 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

4278-695: 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 . Japan declared war on Germany before seizing territories in the Pacific, which later became the South Seas Mandate , as well as German Treaty ports on

4416-545: The Austro-Hungarian Army , Lieutenant Gunther Burstyn , designed a tracked armoured vehicle in 1911 carrying a light gun in a rotating turret; equipped also with hinged 'arms', two in front and two at the rear, carrying wheels on the ends to assist with obstacles and trenches, it was a very forward-looking design, if rather small. The Austro-Hungarian government said that it would be interested in evaluating it if Burstyn could secure commercial backing to produce

4554-419: The Battle of Flers-Courcelette (part of the Battle of the Somme ) on Friday 15 September 1916, with mixed results. Many broke down, but nearly a third succeeded in breaking through. Of the forty-nine tanks shipped to the Somme, only thirty-two were able to begin the first attack in which they were used, and only nine made it across "no man's land" to the German lines. The tanks had been rushed into combat before

4692-675: The British Army on 2 February 1916. Although initially termed "Landships" by the Landship Committee , production vehicles were named "tanks", to preserve secrecy. The term was chosen when it became known that the factory workers at William Foster referred to the first prototype as "the tank" because of its resemblance to a steel water tank. The French fielded their first tanks in April 1917 and ultimately produced far more tanks than all other countries combined. The Germans , on

4830-599: The British Army , a (small) section of which wanted to evaluate artillery tractors . At one point in 1908, Major William E. Donohue of the Mechanical Transport Committee remarked to Roberts that he should design a new machine with armour that could carry its own gun. However, disheartened by years of ultimately-fruitless tinkering for the Army, Roberts did not take up the idea. In later years, he expressed regret at not having pursued it. An engineer in

4968-599: The Caribbean Sea . Eastbound HX convoys and SC convoys worked in reverse forming with a few WLEF escorts in New York City and picking up others as ships joined from New England ports or the Maritimes . Short range escorts or escorts experiencing mechanical problems might be similarly detached and replaced at intermediate points between WOMP and New York City. The most frequent location for escort exchanges

5106-466: The Pedrail wheel , it was essentially an armoured steam tractor equipped with cannon and rotating scythes sprouting from the sides. Lord Palmerston is said to have dismissed it as 'barbaric'. From 1904 to 1909, David Roberts, the engineer and managing director of Hornsby & Sons of Grantham , built a series of tractors using his patented 'chain-track', which were put through their paces by

5244-558: The Renault FTs and Mark IV performed reasonably well. The Mark I's rhomboid shape, caterpillar tracks, and 26-foot (8 m) length meant that it could negotiate obstacles, especially wide trenches, that wheeled vehicles could not. Along with the tank, the first self-propelled gun (the British Gun Carrier Mk I ) and the first armoured personnel carrier followed the invention of tanks. The conceptual roots of

5382-681: The Royal Naval Air Service Armoured Car Division, the only British unit fielding AFVs in 1914. Surprisingly, until the end of the war, most experimentation on heavy land vehicles was conducted by the Royal Naval Air Service Squadron 20. At first, protecting heavy gun tractors with armour appeared the most promising line of development. Alternative early 'big wheel' designs on the lines of the Russian tsar tank of 1915 were soon understood to be impractical. However, adapting

5520-721: 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,

5658-772: 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

5796-487: 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

5934-821: 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

6072-588: 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

6210-563: 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

6348-441: 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

6486-405: The 400 built were ever operational at the same time. Then industrial rivalry began to play a detrimental role: it created the heavy Char St Chamond , a parallel development not ordered by the Army but approved by government through industrial lobbying, which mounted much more impressive weaponry—its 75mm was the most powerful gun fielded by any operational tank up until 1941—but also combined many of

6624-569: 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,

6762-646: 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

6900-553: 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 ,

7038-404: The Central Powers. However, the pro-German King Constantine I dismissed the pro-Allied government of Eleftherios Venizelos before the Allied expeditionary force arrived. 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

7176-649: The Chinese Shandong peninsula at Tsingtao . 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

7314-581: The French used tanks for the first time on 16 April 1917, during the Nivelle Offensive , they had four times more tanks available. But that did not last long as the offensive was a major failure; the Schneiders were badly deployed and suffered 50% losses from German long-range artillery. The Saint-Chamond tanks, first deployed on 5 May, proved to be so badly designed that they were unable to cross

7452-623: 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

7590-585: 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

7728-699: 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

7866-426: 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

8004-425: The Halifax-based Western Local Escort Force in February 1942 as German U-boats began patrolling North American coastal waters during the " second happy time ". The Royal Navy provided the WLEF with twelve old, short-range destroyers well-equipped for anti-submarine warfare and manned by experienced personnel. Newly commissioned Canadian Flower-class corvettes and Bangor -class minesweepers were assigned to

8142-511: The MOEF escort groups, and WLEF escorts seldom worked with the same team of ships through successive convoys. A WLEF escort group would typically meet a westbound ON convoy at WOMP and then individual WLEF ships would be detached with elements of the convoy proceeding separately to Halifax, Sydney, Nova Scotia , Quebec ports on the St. Lawrence River , Saint John, New Brunswick , Boston, Massachusetts , or New York City . Some WLEF escorts were assigned to coastal convoys reaching as far south as

8280-565: 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

8418-545: 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,

8556-449: 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

8694-549: 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

8832-428: The Schneider CA's faults with an even larger overhanging body. Its innovative petro-electrical transmission, while allowing for easy steering, was insufficiently developed and led to a large number of breakdowns. But industrial initiative also led to swift advances. The car industry, already used to vehicle mass production and having much more experience in vehicle layout, designed the first practical light tanks in 1916,

8970-429: 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

9108-552: The WLEF. Town-class destroyers St. Clair , Columbia , and Niagara were assigned to the WLEF after their endurance proved inadequate for MOEF assignments. During the winter of 1942–43, some of these destroyers were organized into Western Support Force (WSF) groupings of three ships to augment protection of convoys coming under attack in the western Atlantic. The WLEF was theoretically organized into eight escort groups able to provide an escort of four to six ships to each convoy. WLEF escort group assignments were more dynamic than

9246-455: 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

9384-430: 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

9522-426: The advancing infantry. Churchill, in turn, wrote a note on 5 January to Prime Minister H. H. Asquith and warned that the Germans might any moment introduce a comparable system. A worried Asquith now ordered Kitchener to form a committee, headed by General Scott-Moncrieff , to study the feasibility of Swinton's idea; however, after trials with a Holt 75 horsepower machine, the committee concluded in February 1915 that

9660-446: 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

9798-407: 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

9936-543: 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

10074-483: 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

10212-549: 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,

10350-649: 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

10488-466: 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,

10626-520: 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,

10764-604: The crates and the tanks themselves were then each labeled with a destination in Russian, "With Care to Petrograd ". In fact, the tanks were never shipped in crates: the inscription in Russian was applied on the hull for their transport from the factory to the first training centre at Thetford. The first fifty had been delivered to France on 30 August. They were 'male' or 'female', depending upon whether their armament comprised two 6-pounder cannons and three Hotchkiss machine guns or four Vickers machine guns and one Hotchkiss. It had

10902-522: 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

11040-449: 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

11178-965: 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

11316-464: 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

11454-471: The design was mature enough (against the wishes of Churchill and Ernest Swinton ) and the number was small but their use gave important feedback on how to design newer tanks, the soundness of the concept and their potential to affect the course of the war. On the other hand, the French Army was critical of the British employment of small numbers of tanks at the battle. It felt the British had sacrificed

11592-476: The development process was slow until in July they received political, even presidential, support by combining their project with that of a mechanical wire cutter devised by engineer and politician Jean-Louis Bréton. In December 1915, the influential Colonel Estienne made the Supreme Command very enthusiastic about the idea of creating an armoured force based on these vehicles; strong Army support for tanks

11730-426: The engine and cordite fumes from the weapons. Temperatures inside could reach 50 °C (122 °F ). Entire crews lost consciousness inside the tanks, or collapsed when again exposed to fresh air. Crews learned how to create and leave behind supply dumps of fuel, motor oil, and tread grease, and converted obsolete models into supply vehicles for newer ones. To counter the danger of bullet splash or fragments knocked off

11868-412: The existing Holt Company caterpillar designs, the only robust tracked tractors available in 1915 into a fighting machine, which France and Germany did, was decided against. Although armour and weapon systems were easy to acquire, other existing caterpillar and suspension units were too weak, existing engines were underpowered for the vehicles that the designers had in mind and the ability to cross trenches

12006-641: 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

12144-411: The extra weight was put into an improvement of armour or armament carried, and the vehicles could still not cross very rough terrain. The adoption of caterpillar tracks offered a new solution to the problem. The tracks spread the weight of the vehicles over a much greater area, all of which was for traction to move the vehicle. The limitation on armour and firepower was no longer the ground pressure but

12282-419: The first line of German trenches. Germany concentrated more on the development of anti-tank weapons than on development of tanks themselves. They only developed one type of tank which saw combat in the war. The A7V Sturmpanzerwagen was designed in 1917 and was used in battle from March 1918. It was manned by a crew of 18, and had eight machine guns and a 57-millimetre cannon. Only 20 A7Vs were produced during

12420-400: 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

12558-595: 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

12696-542: 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

12834-549: 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

12972-521: The idea was impractical. Churchill, however, decided that unless the Army took up the idea, the Navy should proceed independently, even if it exceeded the limits of his authority. He created the Landship Committee in February 1915, initially to investigate designs for a massive troop transporter. As a truer picture of front-line conditions was developed the aims of the investigation changed. A requirement

13110-491: The inside of the hull, the crew wore helmets with goggles and chainmail masks. Fragments were not as dangerous as fire, because of explosive fumes and the large amount of fuel aboard; smoking was prohibited inside and within 20 yards outside tanks. Gas masks were also standard issue, as they were to all soldiers at this point in the war due to the use of chemical warfare . The side armour of 8 mm initially made them largely immune to small arms fire, but could be penetrated by

13248-470: 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

13386-654: The line, but these forces were too weak to re-establish a front. Tanks in World War I The development of tanks in World War I was a response to the stalemate that developed on the Western Front . Although vehicles that incorporated the basic principles of the tank (armour, firepower, and all-terrain mobility) had been projected in the decade or so before the War, it was the alarmingly heavy casualties of

13524-465: 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

13662-520: The other hand, began development only in response to the appearance of Allied tanks on the battlefield. Whilst the Allies manufactured several thousand tanks during the war, Germany deployed only 18 of its own. The first tanks were mechanically unreliable. There were problems that caused considerable attrition rates during combat deployment and transit. The heavily shelled terrain was impassable to conventional vehicles, and only highly mobile tanks such as

13800-568: The power and weight of the power-plant. The remaining issue was how to use and configure a vehicle. Major Ernest Dunlop Swinton of the Royal Engineers was the official British war correspondent serving in France in 1914 and recounted in his book Eyewitness how the idea of using caterpillar tracks to drive an armoured fighting vehicle came to him on 19 October 1914 while he was driving through northern France. In July 1914, he had received

13938-450: The principal inventors of the Tank were Sir William Tritton , managing director of Fosters, and Major Walter Gordon Wilson. Fosters returned to manufacturing Traction engines and steam lorries, but incorporated a small trademark outline image of a tank on the front smokebox door of their postwar road locomotives. During WWII, Tritton and Wilson were called upon to design a Heavy tank , which

14076-801: 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

14214-446: The real battlefield of World War I, one of the most difficult battlefield terrains in history. Despite their reliability problems, when they worked, they could cross trenches or craters of 9 feet (2.7 m) and drive right through barbed wire. It was still common for them to get stuck, especially in larger bomb craters, but overall, the rhomboid shape allowed for extreme terrain mobility. Most World War I tanks could travel only at about

14352-433: The recently developed armour-piercing K bullets . There was also the danger of being overrun by infantry and attacked with grenades. The next generation had thicker armour, making them nearly immune to the K bullets. In response, the Germans developed a larger purpose-made anti-tank rifle , the 3.7 cm TAK 1918 anti-tank gun, and also a Geballte Ladung ("Bunched Charge")—several regular stick grenades bundled together for

14490-488: The secrecy of the weapon but used it in numbers too small to be decisive. Since the British attack was part of an Anglo-French offensive, and the Russians were attacking at the same time, Haig felt justified in making a maximum effort, regardless of the limitations of the tank force. Tank crews who had read press reports depicting the new weapon driving through buildings and trees, and crossing wide rivers, were disappointed. The Mark I's were nonetheless capable of performing on

14628-582: The several committee members. Col R.E.B. Crompton , a veteran military engineer and electrical pioneer, drafted numerous designs with Lucien Legros for armoured troop carrying vehicles and gun-armed vehicles, to have used either Bullock tracks or variants of the Pedrail. At the same time, Lt Robert Macfie, of the RNAS, and Albert Nesfield, an Ealing -based engineer, devised a number of armoured tracked vehicles, which incorporated an angled front 'climbing face' to

14766-453: The start of its trench warfare that stimulated development. Research took place in both Great Britain and France, with Germany only belatedly following the Allies' lead. In Great Britain, an initial vehicle, nicknamed Little Willie , was constructed at William Foster & Co. , during August and September 1915. The prototype of a new design that became the Mark I tank was demonstrated to

14904-829: The summer of 1943. 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 the Asia-Pacific , and in Europe was characterised by trench warfare ;

15042-553: The tank go back to ancient times, with siege engines that were able to provide protection for troops moving up against stone walls or other fortifications. With the coming of the Industrial Revolution and the demonstrable power of steam , James Cowan presented a proposal for a Steam Powered Land Ram in 1855, towards the end of the Crimean War . Looking like a helmet on 'footed' Boydell wheels, early forerunners of

15180-469: 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

15318-580: The term "tank" was established among British and also German soldiers. While in German Tank specifically refers to the World War I type (as opposed to modern Panzer ), in English, Russian and other languages the name even for contemporary armored vehicles is still based on the word tank . It is sometimes mistakenly stated that, after completion, the tanks were shipped to France in large wooden crates. For secrecy and in order to not arouse any curiosity,

15456-691: 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

15594-422: The time to be properly recognised at their just value. The Commission on Awards to Inventors in 1919, which adjudicated all the competing claims to the development of the tank, recognised the brilliance of De Mole's design and even considered that it was superior to the machines actually developed, but its narrow remit allowed it only to make a payment of £987 to De Mole to cover his expenses. He noted in 1919 that he

15732-519: The tracks. The two men fell out bitterly as their plans came to nought; Macfie in particular pursued a vendetta against the other members of the Landships Committee after the war. To resolve the threatened dissipation of effort, it was ordered in late July that a contract was to be placed with William Foster & Co. Ltd , a company having done some prewar design work on heavy tractors and known to Churchill from an earlier experiment with

15870-448: The value of tanks. In fact, horse cavalry doctrine in World War I was to "follow up a breakthrough with harassing attacks in the rear", but there were no breakthroughs on the Western Front until the tanks came along. Despite these supposed views of Haig, he made an order for 1,000 tanks shortly after the failure at the Somme and always remained firmly in favour of further production. In 1919, Major General Sir Louis Jackson said: "The tank

16008-528: The vehicles had been told they were producing "mobile water tanks" for desert warfare in Mesopotamia . Water Container was therefore considered but rejected because the committee would inevitably be known as the WC Committee (WC meaning water closet was a common British term for a toilet ). The term tank , as in water tank, was in December 1915 accepted as its official designation. From then on,

16146-469: The very small number of just ten, but it was the first tank with a three-man turret; the heaviest to enter service until late in World War II and still the largest ever operational tank. French production at first lagged behind the British. After August 1916 however, British tank manufacture was temporarily halted to wait for better designs, allowing the French to overtake their allies in numbers. When

16284-537: 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

16422-601: 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

16560-481: The war, with over 3700 built, more numerous than all British and German tanks combined. That this would happen was at first far from certain; some in the French army lobbied for the alternative mass production of super-heavy tanks. Much design effort was put in this line of development resulting in the gigantic Char 2C , the most complex and technologically advanced tank of its day. Its very complexity ensured it being produced too late to participate in World War I and in

16698-418: 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

16836-406: 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 was a major factor in

16974-457: Was a constant during the decades that followed. Already in January and February 1916, quite substantial orders were made at that moment with a total number of 800, much larger than the British ones. Army enthusiasm and haste had its immediate drawbacks however. As a result of the involvement of inexperienced army officers ordered to devise a new tank based on the larger 75 hp Holt chassis in

17112-442: Was a freak. The circumstances which called it into existence were exceptional and not likely to recur. If they do, they can be dealt with by other means." France at the same time developed its own tracked AFVs, but the situation there was very different. In Britain a single committee had coordinated design, and had to overcome the initial resistance of the Army, while the major industries remained passive. Almost all production effort

17250-402: Was agreed on in late September for trials in early 1916, and the resulting 30 ton "Big Willie" (later called "Mother") together with "Little Willie" underwent trials at Hatfield Park on 29 January and 2 February. Attendees at the second trial included Lord Kitchener , Lloyd George , Reginald McKenna and other political luminaries. On 12 February an initial order for 100 "Mother" type vehicles

17388-403: 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

17526-692: Was formulated for an armoured vehicle capable of 4 mph (6.4 km/h), climbing a 5 feet (1.5 m) high parapet, crossing an 8 feet (2.4 m) wide gap, and armed with machine guns and a light artillery piece. A similar proposal was working its way through the Army GHQ in France, and in June, the Landships Committee was made a joint service venture between the War Office and the Admiralty. The Naval involvement in Armoured Fighting Vehicle (AFV) design had originally come about through

17664-639: Was known as TOG1 , (named for "The Old Gang"), but this was not a success. However, Lincoln City erected a full-size outline Mk 1 as a memorial to the invention of the tank in 2015, and placed it on the Tritton Road roundabout. For secrecy, the six new tank companies were assigned to the Heavy Section of the Machine Gun Corps . The first use of tanks on the battlefield was the use of British Mark I tanks by C and D Companies HS MGC at

17802-400: Was made, later expanded to 150. Crews rarely called tanks "Willies"; at first they referred to them as "cars", and later informally "buses". Although landship was a natural term coming from an Admiralty committee, it was considered too descriptive and could give away British intentions. The committee, therefore, looked for an appropriate code term for the vehicles. Factory workers assembling

17940-409: Was planned with a 40 mm gun but abandoned due to weight problems, leaving the final vehicle unarmed and little more than a test-bed for the difficult track system. Difficulties with the commercial tracks supplied led to Tritton designing a completely new track system different from, and vastly more robust than, any other system then in use. The next design by Lieutenant Walter Gordon Wilson RNAS,

18078-422: Was poor because of the shortness of the wheelbase . The Killen-Strait tractor with three tracks was used for the first experiments in June but was much too small to be developed further. The large Pedrail monotrack vehicle was proposed in a number of different configurations, but none were adopted. Trials to couple two American Bullock tractors failed. There also were considerable differences of opinion between

18216-654: 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,

18354-667: 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

18492-436: Was that it was very hard to add much protection or armament. The main limitation was the wheels, which gave a high ground pressure for the vehicle's weight. That could be solved by adding more wheels, but unless they also were driven, the effect was to reduce traction on the powered wheels. Driving extra wheels meant more drive train weight, which required a larger and heavier engine to maintain performance. Even worse, none of

18630-547: Was the Halifax Ocean Meeting Point (HOMP) off the WLEF home port of Halifax. The WLEF operated exclusively within range of anti-submarine patrol bombers; although weather often limited flight operations. U-boats were deployed cautiously in areas where air patrols were expected, so single U-boat encounters were more common than wolf pack engagements. The name was shortened to "Western Escort Force" (WEF) in

18768-781: 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

18906-534: Was thus concentrated into the Mark I and its direct successors, all very similar in shape. In France, on the other hand, there were multiple and conflicting lines of development which were badly integrated, resulting in three major and quite disparate production types. A major arms producer, Schneider, took the lead in January 1915 and tried to build a first armoured vehicle based on the Baby Holt tractor but initially

19044-560: Was urged by friends before the war to approach the Germans with his design but declined to do so for patriotic reasons. Before World War I , motorised vehicles were still relatively uncommon, and their use on the battlefield was initially limited, especially of heavier vehicles. Armoured cars soon became more common with most belligerents, especially in more-open terrain. On 23 August 1914 the French Colonel Jean Baptiste Eugène Estienne , later
