117-717: The Australian Corps was a World War I army corps that contained all five Australian infantry divisions serving on the Western Front . It was the largest corps fielded by the British Empire in France. At its peak the Australian Corps numbered 109,881 men. By 1918 the headquarters consisted of more than 300 personnel of all ranks, including senior staff officers, as well as supporting personnel such as clerks, drivers and batmen. Formed on 1 November 1917,

234-523: 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

351-645: 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

468-493: A division and roughly equal to or a little larger than a regiment . During the American Civil War infantry brigades contained two to five regiments with the idea being to maintain a unit with a strength of 2,000 soldiers and were usually commanded by a brigadier general or a senior colonel. During World War I the division consisted of two brigades of two regiments each. More recently, the U.S. Army has moved to

585-592: 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,

702-540: 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

819-413: A "battle group", viz., brigada or "brigade" commanded by a senior colonel, or lieutenant colonel, appointed as a brigadier-general . In France, Marshal Turenne (1611–1675) copied the brigade organization; he made it a permanent standing unit, requiring the creation in 1667 of a permanent rank of brigadier des armées du roi (literally translating to "brigadier of the armies of the king"). Unlike

936-553: A MEB, available for deployment on expeditionary duty . The MEB is the intermediate MAGTF between the MEF and the marine expeditionary unit (MEU). Along with the marine infantry regiments, the MEU, (while smaller than an army brigade), are the USMC organizational equivalents of army brigades. The MEU consists of three battalion-equivalent-sized units and a command element (a battalion landing team,

1053-508: A brigade is not part of any division and is under direct command of a corps. There are 7 independent armoured brigades, seven engineering brigades and eight air defense brigades. Independent armoured and infantry brigades are capable of extended operations without necessarily being reliant on a higher HQ for short-term logistic or intimate support. They can be used in counter-attack, exploitation of an advance, or rapid movement to reinforce formations under pressure. Prior to major restructures of

1170-607: A brigade may comprise both organic elements and attached elements, including some temporarily attached for a specific task. Brigades may also be specialized and comprise battalions of a single branch, for example cavalry, mechanized, armored, artillery, air defence, aviation, engineers, signals or logistic. Some brigades are classified as independent or separate and operate independently from the traditional division structure. The typical NATO standard brigade consists of approximately 5,000 troops. However, in Switzerland and Austria,

1287-413: A brigadier general. The MEB is a mid-level marine air-ground task force (MAGTF) essentially forming a "demi-division". The MEB organizational structure consists of a minimum of three regimental-equivalent-sized units and a command element (a regimental combat team, a composite marine aircraft group, a marine logistics regiment, and a MEB headquarters group). Each marine expeditionary force (MEF) contains

1404-541: A brigadier. In the Second World War, a tank brigade comprised three tank regiments and was equipped with infantry tanks for supporting the infantry divisions. Armoured brigades were equipped with cruiser tanks or (US Lend-Lease ) medium tanks and a motorised infantry battalion. The armoured divisions included one or more armored brigades. In the United States Army , a brigade is smaller than

1521-434: A captain) reporting directly to the field force or "army" commander. As such a "field army" became larger, the number of subordinate commanders became unmanageable for the officer in general command of said army, usually a major general, to effectively command. In order to streamline command relationships, as well as effect some modicum of tactical control, especially in regard to combined arms operations (i.e., those involving

1638-408: 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

1755-850: A coordination of infantry with cavalry and/or artillery forces), an intermediate level of command came into existence. The Swedish king Gustavus Adolphus improved the brigade as a tactical unit, introducing it in 1631 during a reorganization of the Swedish Army in the course of the Thirty Years' War . The invention of the brigade overcame the lack of coordination inherent in the traditional army structure consisting of independent regiments of infantry and units of supporting arms (viz., cavalry and artillery) acting separately under their individual commanding officers. Gustavus Adolphus accomplished this battlefield coordination by combining battalions of infantry with cavalry troops and artillery batteries into

1872-613: 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

1989-471: 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,

2106-477: A logistics battalion. Mountain brigades have also a special forces (called "Mountain rangers") company. The brigade is usually commanded by a brigadier general or a senior colonel, who may be promoted to general during his tenure as brigade commander. In the Australian Army , the brigade has always been the smallest tactical formation , since regiments are either administrative groupings of battalions (in

2223-478: A marine medium tilt-rotor squadron (reinforced), a combat logistics battalion, and a MEU headquarters group). The marine infantry regiments, combined with the marine artillery regiments, comprise the bulk of the marine divisions. An example of a MEB is Task Force Tarawa ( 2nd Marine Expeditionary Brigade ) during the Operation Iraqi Freedom campaign. In Myanmar, a rough equivalent of a Brigade

2340-498: A new generic brigade combat team (BCT) in which each brigade contains combat elements and their support units. After the 2013 reform , BCT personnel strength typically ranges from 4,400 personnel for infantry BCTs, to 4,500 personnel for Stryker BCTs, to 4,700 personnel for armoured BCTs. This formation is standard across the active U.S. Army, U.S. Army Reserve , and the Army National Guard . The brigade commander

2457-447: A particular brigade (as a "brigade group"). Historically, infantry or cavalry/armoured brigades have usually comprised three or four combat-arm battalions, but currently larger brigades are normal, made larger still when their affiliated artillery and engineer regiments are added. Until 1918, the chief of staff of a brigade was known as a brigade major . Before 1922, British Army brigades were normally commanded by general officers holding

2574-548: 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

2691-834: 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

2808-476: A self-contained headquarters and staff. The principal staff officer, usually a lieutenant colonel or colonel, may be designated chief of staff. Until the late 20th century British and similar armies called the position 'brigade-major' and most British brigades have a major as the chief of staff. Some brigades may also have a deputy commander. The headquarters has a nucleus of staff officers and support (clerks, assistants and drivers) that can vary in size depending on

2925-516: 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

3042-498: A single brigade-level command. The PLAGF distinguishes three distinct types of combined arms brigades: light (motorized), medium (mechanized), and heavy (armoured). These distinctive types are more indicative of the role of the organization within its parent unit than the composition and equipment which vary and overlap between types. A light combined arms brigade may be designed as an airborne , mountain , or amphibious combined arms brigade. A combined arms brigade typically comprises

3159-478: 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

3276-402: 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

3393-455: 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

3510-429: Is called a Tactical Operation Command. It's just a rough equivalent as a Tactical Operation Command has 3 Infantry Battalions under its command, there're no such Brigade troops or anything, instead those units such as Military Engineer, Signal, Medical and etc are supposed to be organic to the battalions (sometimes called Regiments). A Tactical Operation Command HQ only consist of 4 Officers and 4 Other Ranks. Theoritically,

3627-479: Is first attested in England in the 17th century as a term for a larger military unit than the squadron or regiment. It was first adopted when armies began to consist of formations larger than a single regiment. Previously each regiment, battalion, cavalry squadron, or artillery battery operated somewhat independently, with its own field officer (i.e., colonel, lieutenant colonel, or major) or battery commander (usually

3744-508: 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

3861-464: Is usually a colonel, although a lieutenant colonel can be selected for brigade command in lieu of an available colonel. A typical tour of duty for this assignment is 24 to 36 months. Separate brigades, viz., brigades not permanently assigned to a division , were commanded by brigadier generals. A brigade commander has a headquarters and staff to assist them in commanding the brigade and its subordinate units. The typical staff includes: In addition,

3978-574: 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

4095-641: 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

4212-569: The 3rd Division ). Monash, who was senior, had experience commanding troops in battle and was favoured by Haig and Birdwood, got the post in May 1918 and was promoted to lieutenant general . The Australian Corps was used extensively throughout the Hundred Days Offensive during which it achieved great success. The 4th Division saw little rest in its role as the "depot". In December 1917 it was moved into reserve near Péronne following

4329-695: 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

4446-535: The British Expeditionary Force , accepted this proposal. He had originally resisted combining the five Australian divisions into a single corps as he considered it too unwieldy. The Australian nature of the corps was enhanced by the attachment of No. 3 Squadron AFC plus Australian siege artillery batteries. It was also considered appropriate to appoint Australian officers to all senior command positions. However, Birdwood remained in command of

4563-696: The Canadian Army has three Regular Force brigade groups, designated as Canadian mechanized brigade groups (CMBG): 1 CMBG , 2 CMBG , which contain the regular army's Anglophone units, and 5 CMBG , the regular Francophone formation. These CMBGs each comprise Co-located with each CMBG is a field ambulance , a tactical helicopter squadron, and a military police platoon. Regular Force CMBG's strengths are 5,000 personnel. Canada also has ten Primary Reserve brigades (Canadian brigade group, CBG), 31 CBG through 39 CBG, and 41 CBG. The CBG formations are for administrative purposes. On 1 January 1791, France replaced

4680-499: The Franco-German Brigade . There is also an airmobile brigade subordinated to the army aviation command. In peacetime, brigades serve primarily as force providers. The units deployed (battlegroups and task-forces) are battalion-size units provided by the regiments composing the brigades. In Indian army, a brigade consists of a HQ, three battalions along with supporting troops. It is commanded by an army officer of

4797-649: The People's Liberation Army Ground Force (PLAGF), forces were designed around the division as the basic operational unit in a similar fashion to Soviet divisions, from which much of the People's Liberation Army (PLA) is designed. In 2003, the United States Army pivoted from division-centric warfare to combined-arms-centric warfare in response to the U.S. War in Iraq creating the brigade combat team (BCT). The Russian Federation followed suit reorganizing their forces and doctrine to switch from division-centric warfare to

4914-721: 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,

5031-828: The United States entered the war on the Allied side following Germany's resumption of unrestricted submarine warfare against Atlantic shipping. Later that year, the Bolsheviks seized power in the Russian October Revolution , and Soviet Russia signed an armistice with the Central Powers in December, followed by a separate peace in March 1918. That month, Germany launched an offensive in

5148-487: 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

5265-403: The infantry ) or battalion-sized units (in the cavalry ). A typical brigade may consist of approximately 5,500 personnel between two mechanised infantry battalions, an armoured regiment, an armoured artillery regiment, and other logistic and engineering units. The brigade is usually commanded by an officer holding the rank of brigadier, who is referred to as the "Brigade Commander". As of 2024 ,

5382-821: 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

5499-588: 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

5616-563: 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

5733-441: 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

5850-539: The Argentinian Army, the typical brigade comprises an HQ company, two or three battalions (called "regiments" for historical reasons) of the brigade's main branch (infantry or armoured cavalry), which give the brigade its denomination (mechanized, armoured, airborne, mountain or jungle), plus one battalion of the other branch, plus one or two artillery groups, an engineers battalion or company, a signals company, and intelligence company, an army aviation section and

5967-569: 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,

SECTION 50

6084-646: 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

6201-553: 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 ,

6318-404: 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

6435-649: 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

6552-623: 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

6669-640: 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

6786-472: The German counter-attack in the Battle of Cambrai . In January 1918, the division was returned to the front line south of Ypres as Haig acquiesced to French demands to take over more of the front. From this time until the Australians were withdrawn from fighting in early October, all divisions of the corps saw nearly continuous action. Rather than disbanding entire divisions, any consolidation of strength

6903-752: 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

7020-486: 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

7137-495: The JGSDF, with some of them formed from former divisions. A brigade in the JGSDF consists of 3,000–4,000 soldiers and is led by a major general . A brigade is under the command of a brigadier and comprises three or more battalions of different units depending on its functionality. An independent brigade would be one that primarily consists of an artillery unit, an infantry unit, an armour unit and logistics to support its actions. Such

7254-565: 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

7371-545: 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,

7488-449: 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

7605-549: 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

7722-429: 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

7839-439: The Swedish brigades, French brigades at that time comprised two to five regiments of the same branch ( brigade de cavalerie, brigade d'infanterie etc.). The rank, intermediate between colonel and maréchal de camp , disappeared in 1788 and should not be confused with that of général de brigade , which is equivalent to a brigadier general. (A modern général de brigade is referred to occasionally as brigadier .) In

7956-455: 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

8073-402: The Western Front. The Corps comprised 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

8190-430: 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

8307-446: 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

8424-474: 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

8541-543: 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

8658-483: 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

8775-549: 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,

8892-649: 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

9009-466: 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,

9126-553: The combat ready support contingent is also intended to complement the Heimevernet (translates as "Home Defense") which is a large reserve infantry force, as well as act in a support capacity for an international cooperation force (e.g. NATO) in case of an invasion. Brigades in the Japan Ground Self-Defense Force (JGSDF) are combined arms and are similar to divisions. There are eight brigades in

9243-661: The corps replaced I Anzac Corps while II Anzac Corps , which contained the New Zealand Division , became the British XXII Corps on 31 December. While its structure varied, Australian Corps usually included 4–5 infantry divisions, corps artillery and heavy artillery, a corps flying squadron and captive balloon sections, anti-aircraft batteries, corps engineers, corps mounted troops (light horse and cyclists), ordnance workshops, medical and dental units, transport, salvage and an employment company. Following

9360-725: The corps. General Hubert Gough was dismissed from command of the British Fifth Army following its failure to withstand the German Spring Offensive of 1918. When Haig decided to reform the Fifth Army, he offered its command to Birdwood who accepted. This paved the way for an Australian to assume command of the corps, the highest field command held by an Australian in the war. The two candidates were Major General Cyril Brudenell White (Birdwood's chief-of-staff) and Major General John Monash (commander of

9477-520: 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,

9594-522: 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

9711-449: 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

9828-965: 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

9945-695: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany. After the 1877–1878 Russo-Turkish War , the League was dissolved due to Austrian concerns over the expansion of Russian influence in the Balkans , an area they considered to be of vital strategic interest. Germany and Austria-Hungary then formed

10062-400: 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

10179-491: The following organic units wherein the maneuver battalions vary between motorized , mechanized , or armoured depending on the type of CA-BDE. An NRA Brigade, 旅 ( lǚ ), was a military formation of the Chinese Republic 's National Revolutionary Army . Infantry and cavalry brigades comprised two infantry regiments. After the 1938 reforms, the brigade was dispensed with within the infantry division in favour of

10296-595: 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

10413-542: 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

10530-601: The hard fighting of 1917, where the Australian divisions suffered heavily at Bullecourt , Messines and the Third Battle of Ypres , the Australian Imperial Force (AIF) was facing a manpower crisis. One plebiscite for conscription had already failed and another would be defeated on 1 December 1917. Voluntary recruitment was declining. Plans to form a 6th Australian Division were scrapped and

10647-579: The headquarters includes additional junior staff officers, non-commissioned officers , and enlisted support personnel in the occupational specialities of the staff sections; these personnel are ordinarily assigned to the brigade's headquarters and headquarters company . Functional brigades are those from the combat support or combat service support arms. In the United States Marine Corps , brigades are designated as marine expeditionary brigades (MEB) and are usually commanded by

10764-549: 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

10881-547: The incomplete formation was disbanded. To make up the numbers, it was proposed to disband the Australian 4th Division , numerically the weakest, but this was strongly resisted by the members of the AIF. General William Birdwood , commander of the AIF, suggested that in forming the Australian Corps, the weakest division could serve as a depot, providing reserves for the fighting divisions. Field Marshal Douglas Haig , commander of

10998-470: 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

11115-409: The line, but these forces were too weak to re-establish a front. Brigade Brigades formed into divisions are usually infantry or armored (sometimes referred to as combined arms brigades). In addition to combat units, they may include combat support units or sub-units, such as artillery and engineers, and logistic units. Historically, such brigades have been called brigade-groups. On operations,

11232-400: The numbers could start as high as 10,000 troops. The Soviet Union, its forerunners and successors, mostly uses "regiment" instead of brigade, and this was common in much of Europe until after World War II. A brigade's commander is commonly a major general , brigadier general , brigadier or colonel . In some armies, the commander is rated as a general officer . The brigade commander has

11349-465: 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

11466-801: 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

11583-598: The rank of Brigadier (Single star commander). The main core of the Norwegian Army is the Brigade Nord , consisting of eight battalions of which four are combat battalions (one infantry, one mechanized infantry, one artillery and one armored) and the rest are various types of support battalions. The brigade is intended to be combat ready at all times. The combat battalions have a significant portion of professional soldiers (specialists). The fairly large size of

11700-543: The rank of brigadier-general (equivalent to a "one-star" rank in the US Army); after that date, the brigade commander was an appointment for officers with the rank of brigadier, which were then classified as field officers not general officers. This is universally the case today. From 1859 to 1938, "brigade" ("brigade-division" 1885–1903) was also the term used for a battalion-sized unit of the Royal Artillery . This

11817-492: The regiment to simplify the command structure. Brigades, with a field not a regional administrative role, have usually been of a named type and numbered since the 19th century (e.g. cavalry brigade or infantry brigade). Since the end of World War II, brigade numbers have been unique and not by type. Brigades in divisions do not usually command their combat support and combat service support units. These remain under divisional command, although they may be permanently affiliated with

11934-469: 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

12051-691: 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

12168-473: The type of brigade. On operations, additional specialist elements may be attached. The headquarters will usually have its own communications unit. In some gendarmerie forces, brigades are the basic-level organizational unit. Borrowed from the French cognate word brigade , the term originates from the Italian noun brigata , itself derived from the Italian verb brigare , to contend or fight. The word

12285-520: The use of battalion tactical groups (BTGs). Finally, the PLAGF, as part of a larger restructuring, underwent the so-called "brigade-ization" making PLAGF divisions a largely administrative echelon and moving forces into combined arms brigades (CA-BDE). Structured very similarly to U.S. Army BCTs, the PLAGF combined arms brigade places maneuver , artillery , air defense , reconnaissance , engineer and protection , and logistics and sustainment under

12402-645: 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

12519-601: 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

12636-418: 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

12753-448: The word "Regiment" that had been associated with the former Royal regime with the term "demi-brigade". France replaced its divisions with brigades in 1999 (so for example the 2nd Armored Division became the 2nd Armored Brigade). It was decided in 2016 to again form two divisions ( 1st and 3rd ) made up of four and three brigades for a total of seven brigades: two armored, two "intermediate", two light brigades (alpine and parachute) and

12870-432: Was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when

12987-511: Was because, unlike infantry battalions and cavalry regiments, which were organic, artillery units consisted of individually numbered batteries that were "brigaded" together. The commanding officer of such a brigade was a lieutenant colonel . In 1938, the Royal Artillery adopted the term "regiment" for this size of unit, and "brigade" became used in its normal sense, particularly for groups of anti-aircraft artillery regiments commanded by

13104-403: 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

13221-423: Was characterised by trench warfare ; the widespread use of artillery , machine guns, and chemical weapons (gas); and the introductions of tanks and aircraft . World War I was one of the deadliest conflicts in history , resulting in an estimated 10 million military dead and more than 20 million wounded , plus some 10 million civilian dead from causes including genocide . The movement of large numbers of people

13338-569: Was made under the British system of reducing brigades from four battalions to three. During the Hundred Days campaign that ended the war, the Australian Corps, along with the Canadian Corps, were used repeatedly as spearheads for offensives. During the period August to October, 1918, General Monash reported that the Australian Corps had defeated some 39 German divisions, a full fifth of the entire German strength of 200 divisions on

13455-654: 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,

13572-667: 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

13689-781: 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
