The Jacket, Field, O.D. (also unofficially known as O.D. Cotton Field Jacket , Parsons Jacket , or M1941 ) is a field jacket that was used by US Army soldiers, most famously during the beginning of World War II . In 1941 it started to be phased in as a replacement for the wool four-pocket service coat of World War I , but around 1943 it was replaced in turn by the improved M1943 model. Owing to wide adoption, the M1941 is usually recognized as a symbol of the World War II American G.I. The jacket was made in a light shade of olive drab called O.D. number 2.
107-466: Through World War I , soldiers in the United States Army wore a comfortable loose-fitting wool four pocket field garment. By the outbreak of World War II, it had changed to a tight-fitting version suitable only for garrison wear. This followed the general pattern adopted by most major armies of the world during the post-WWI period, but proved to be rather impractical. At the end of the 1930s,
214-645: 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
321-592: 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,
428-540: 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
535-408: 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
642-613: 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
749-471: 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,
856-548: 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
963-834: 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
1070-516: 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
1177-478: 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

#17327799062141284-402: 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
1391-455: 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
1498-894: A widespread and prolonged fear of a potential third world war between nuclear-armed powers. It is often suggested that it would become a nuclear war , and be more devastating and violent than both the First and Second World Wars. Albert Einstein is often quoted as having said in 1947 that "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones." It has been anticipated and planned for by military and civil authorities, and it has also been explored in fiction . Scenarios have ranged from conventional warfare to limited or total nuclear warfare. Various former government officials, politicians, authors, and military leaders (including James Woolsey , Alexandre de Marenches , Eliot Cohen , and Subcomandante Marcos ) have attempted to apply
1605-403: A worldwide conflict. That caused a very minute conflict between two countries to have the potential to set off a domino effect of alliances, triggering a world war. The fact that the powers involved had large overseas empires virtually guaranteed that such a war would be worldwide, as the colonies' resources would be a crucial strategic factor. The same strategic considerations also ensured that
1712-508: 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
1819-905: Is the only conflict in which nuclear weapons have been used; both Hiroshima and Nagasaki , in the Japanese Empire , were devastated by atomic bombs dropped by the United States. The main Axis powers were Nazi Germany , the Empire of Japan , and the Kingdom of Italy ; while the United Kingdom , the United States , the Soviet Union and China were the " Big Four " Allied powers. Nazi Germany , led by Adolf Hitler ,
1926-560: Is used by Karl Marx and his associate, Friedrich Engels , in a series of articles published around 1850 called The Class Struggles in France . Rasmus B. Anderson in 1889 described an episode in Teutonic mythology as a "world war" (Swedish: världskrig ), justifying this description by a line in an Old Norse epic poem, " Völuspá : folcvig fyrst I heimi" ("The first great war in the world"). German writer August Wilhelm Otto Niemann used
2033-574: 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
2140-641: 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

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

2461-847: 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 ; the widespread use of artillery , machine guns, and chemical weapons (gas); and
2568-931: The Nine Years' War (1689–1697), the War of the Spanish Succession (1701–1714), the War of the Austrian Succession (1740–1748), the French Revolutionary Wars (1792–1802), and the Napoleonic Wars (1803–1815). British historian John Robert Seeley dubbed all of those wars between France and Great Britain (later the UK) between 1689 and 1815 (including the American Revolutionary War from 1775 to 1783) as
2675-645: The Nine Years' War , the War of the Spanish Succession , the Seven Years' War , the French Revolutionary and Napoleonic Wars , the Cold War , and the War on Terror . The Oxford English Dictionary cited the first known usage in the English language to a Scottish newspaper, The People's Journal , in 1848: "A war among the great powers is now necessarily a world-war." The term "world war"
2782-963: The Old World . Others consider that the Ottoman–Portuguese confrontations and Ottoman–Habsburg wars can be considered as world conflicts, prototypes of the " Great Game " in Eurasia and the Scramble for Africa , but between two main power-projecting and religious blocs, the Ottomans , as holders of the Muslim Caliphate , and the Habsburgs , as Holy Roman Emperor . However, the Americas and Oceania were not involved in those conflicts, in which case, other historians consider
2889-721: 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,
2996-723: The Second Hundred Years' War , echoing an earlier period of conflict between France and England known as the Hundred Years' War (1337–1453). Some writers have referred to the American Revolutionary War alone as a world war. Others (like William R. Thompson or Chase-Dunn and Sokolovsky) also wants to include the Italian Wars and Dutch wars [ Dutch-Spanish and Anglo-Dutch Wars ] as part of Global Wars, while clasificating WW1 and WW2 as
3103-645: The Thirty Years' War and Eighty Years' War (specially Iberian–Dutch War ) as the first global conflict, pitting the Spanish and Portuguese Empires against the French , Dutch , and British Empires and their allies (mostly Protestants , like Danish and Swedish oversea expeditions) across the five continents. Another possible example is the Second Congo War (1998–2003) even though it
3210-766: 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
3317-473: The Yemeni civil war (2014–present), and their worldwide spillovers are sometimes described as proxy wars waged by the United States and Russia, which led some commentators to characterize the situation as a "proto-world war", with many countries embroiled in overlapping conflicts. The Seven Years' War (1754/56–1763) was fought across all of North America, Europe, Asia, Africa, and South America. Most of

3424-423: 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
3531-442: 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
3638-588: 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
3745-431: 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
3852-441: 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
3959-462: The Army moved to adopt a new outer garment that was intended to be more utilitarian and provide better protection in combat. The army's first attempts included adding a pleated "bi-swing" back to the service coat, a change adopted with the M1939 Service Coat, but that proved to be still unsuited for field wear and was relegated to garrison use. The first field jacket was based on a civilian jacket suggested by Major General James K. Parsons , for whom it
4066-409: 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,
4173-593: 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
4280-493: 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 ,

4494-410: 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
4601-548: 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
4708-465: 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
4815-462: 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
4922-426: 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

However, other historians prefer to see all of those conflicts as "Hegemonic Wars" or "General Wars", been inter-regional wars on the grand scale, but not worldly. Other historians suggest even earlier conflicts to be world wars. For example, Russian ethnologist L. N. Gumilyov called

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
5243-703: 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 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
5350-545: 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,

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 .

Its main differences were that it was made with a more water resistant fabric and had buckles for tightening around the wrists and waist instead of buttons.

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

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

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

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

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

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,

Chemical weapons were used in the war despite the Hague Conventions of 1899 and 1907 having outlawed the use of such weapons in warfare. The Ottoman Empire was responsible for the Armenian genocide , during the First World War, as well as other war crimes. The Second World War occurred from 1939 to 1945 and

Japan was responsible for attacking neutral nations without a declaration of war , such as the attack on Pearl Harbor . It is also known for its brutal treatment and killing of Allied prisoners of war and the inhabitants of Asia . It also used Asians as forced laborers and was responsible for the Nanjing Massacre in which 250,000 civilians were brutally murdered by Japanese troops. Noncombatants suffered at least as badly as or worse than combatants , and

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,

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
7383-449: 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
7490-818: 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
7597-441: The distinction between combatants and noncombatants was often blurred by the belligerents of total war in both conflicts. The outcome of the war had a profound effect on the course of world history . The old European empires collapsed or they were dismantled as a direct result of the crushing costs of the war and in some cases, their fall was caused by the defeat of imperial powers. The United States became firmly established as
7704-590: The dominant global superpower , along with its close competitor and ideological foe, the Soviet Union . The two superpowers exerted political influence over most of the world's nation-states for decades after the end of the Second World War. The modern international security, economic, and diplomatic system was created in the aftermath of the war. Institutions such as the United Nations were established to collectivize international affairs, with
7811-643: 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
7918-411: The explicit goal of preventing another outbreak of general war. The wars had also greatly changed the course of daily life. Technologies developed during wartime had a profound effect on peacetime life as well, such as by advances in jet aircraft , penicillin , nuclear energy , and electronic computers . Since the atomic bombings of Hiroshima and Nagasaki during the Second World War, there has been
8025-571: 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
8132-508: The first world war in the full sense of the word", citing a wire service report in the Indianapolis Star on 20 September 1914. In English, the term "First World War" had been used by Lieutenant Colonel Charles à Court Repington , as a title for his memoirs (published in 1920); he had noted his discussion on the matter with a Major Johnstone of Harvard University in his diary entry of September 10, 1918. The term "World War I"
8239-652: 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
8346-542: 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
8453-526: The great powers of the era participated, notably including the British Empire and French Empire , but polities from many continents played important roles. Some historians call it "World War Zero" as a result. Historians like Richard F. Hamilton and Holger H. Herwig created a list of eight world wars, including the two generally agreed-upon world wars, the Seven Years' War, and five others:
8560-549: 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
8667-435: 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 the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of
8774-470: 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
8881-455: The jacket (M-38 Parsons jacket) do not have the shoulder epaulets, but the two front slash pockets had buttoned pocket flaps and a thinner half-belt back seam. When the US entered the war in 1941, the O.D. cotton field jacket was the standard outer garment for all army personnel, except those that had other specialist clothing ( Paratroopers wore the parachutist's coat and trousers, tank crews wore
8988-709: The labels of the "Third World War" and the "Fourth World War" to various past and present global wars since the end of the Second World War, such as the Cold War and the war on terror respectively. During the early 21st century, the war in Afghanistan (2001–2021), the Arab Spring (2010–2012), the Syrian civil war (2011–present), the Iraq War (2003–2011), the Russo-Ukrainian War (2014–present),
9095-447: The light cotton shell provided little protection from wet weather and wind. In addition, the lighter shade of OD 3 faded quickly and resulted in a beige color, thus compromising the effect of camouflage – which troops in the field found out the hard way, and often turned their jackets inside out because the wool lining was a darker shade of O.D. and did not gleam in the sunlight like the poplin shell did. The O.D. cotton field jacket
9202-475: The line, but these forces were too weak to re-establish a front. World war A world war is an international conflict that involves most or all of the world's major powers . Conventionally, the term is reserved for two major international conflicts that occurred during the first half of the 20th century, World War I (1914–1918) and World War II (1939–1945), although some historians have also characterised other global conflicts as world wars, such as
9309-404: The more common beige-green. The jacket had a front zipper front closure with a buttoned storm flap. The jacket also had buttons at the collar for closing the lapels to warm the neck region, as well as buttoned adjusting tabs on each side of the waist and at the cuffs to seal in body heat, and buttoned shoulder epaulets. There were two front slash pockets and a notched lapel collar. Earlier models of
9416-465: 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
9523-738: 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
9630-518: The tanker's jacket, various types of parkas were worn in cold weather, etc.). As a result, the field jacket could be seen worn in every theater of war and by nearly every type of soldier, making it a rather ubiquitous symbol of the World War II American G.I. Throughout the course of the war, the O.D. cotton field jacket proved to be an inadequate outer garment. The jacket's thin lining provided poor insulation during cold weather and
9737-469: 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."

9951-503: The term on its front page, saying "The Second World War broke out yesterday at 11 a.m." Speculative fiction authors had been noting the concept of a Second World War in 1919 and 1920, when Milo Hastings wrote his dystopian novel, City of Endless Night . Other languages have also adopted the "world war" terminology; for example, in French , "world war" is translated as guerre mondiale ; in German , Weltkrieg (which, prior to
10058-636: 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
10165-645: 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
10272-601: 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
10379-587: The war, had been used in the more abstract meaning of a global conflict); in Italian , guerra mondiale ; in Spanish and Portuguese , guerra mundial ; in Danish and Norwegian , verdenskrig ; in Russian , мировая война ( mirovaya voyna ); and in Finnish , maailmansota . The First World War occurred from 1914 to 1918. In terms of human technological history , the scale of World War I
10486-477: 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
10593-403: 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
10700-538: Was coined by Time magazine on page 28 of its June 12, 1939, issue. In the same article, on page 32, the term "World War II" was first used speculatively to describe the upcoming war. The first use for the actual war came in its issue of September 11, 1939. One week earlier, on September 4, the day after France and the United Kingdom declared war on Germany, the Danish newspaper Kristeligt Dagblad used
10807-563: Was enabled by the technological advances of the Second Industrial Revolution and the resulting globalization that allowed global power projection and mass production of military hardware. It had been recognized that the complex system of opposing military alliances (the German and Austro-Hungarian Empires against the British , Italian , Russian , and French Empires) was likely, if war broke out, to lead to
10914-463: Was officially replaced with the adoption of the M1943 uniform ensemble as the standard, which included the much improved M1943 field jacket. The O.D. cotton field jacket was redesignated limited standard and issued until supplies were exhausted. Photographic evidence shows that soldiers continued to wear the older jacket all the way through the end of the war, due to supply shortages and squabbling between
11021-654: 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,
11128-535: Was responsible for genocides , most notably the Holocaust , which murdered demographics considered Untermensch by the Nazis. These included about six million Jews and about five million others, such as Slavs , Roma , homosexuals , and the physically and mentally disabled.

11235-723: 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
11342-781: 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
11449-496: Was unofficially named. Unlike the service coat, the material for the jacket was more wind and water resistant. A further reason for adopting a field jacket made of a different material was that shortages of wool were expected. The jacket could be worn with both winter (OD wool) and summer (khaki chino) uniforms as well as fatigue uniforms. The Olive Drab Cotton Field Jacket was standardized and adopted in June 1940 for use by all members of
