The British Expeditionary Force (BEF) was the six-divisions the British Army sent to the Western Front during the First World War. Planning for a British Expeditionary Force began with the 1906–1912 Haldane Reforms of the British Army carried out by the Secretary of State for War Richard Haldane following the Second Boer War (1899–1902).
The II ANZAC Corps was an Australian and New Zealand First World War army corps. Formed in early 1916 in Egypt in the wake of the failed Gallipoli campaign, it initially consisted of two Australian divisions, and was sent to the Western Front in mid-1916. It then took part in the fighting in France and Belgium throughout 1916 and 1917, during which time it consisted of New Zealand, Australian and British divisions. In November 1917, the corps was subsumed in to the Australian Corps, which concentrated all five Australian infantry divisions. After this, the corps was reformed as the British XXII Corps.
An army group is a military organization consisting of several field armies, which is self-sufficient for indefinite periods. It is usually responsible for a particular geographic area. An army group is the largest field organization handled by a single commander – usually a full general or field marshal – and it generally includes between 400,000 and 1,000,000 soldiers.
The New Zealand Expeditionary Force (NZEF) was the title of the military forces sent from New Zealand to fight alongside other British Empire and Dominion troops during World War I (1914–1918) and World War II (1939–1945). Ultimately, the NZEF of World War I became known as the First New Zealand Expeditionary Force. The NZEF of World War II was known as the Second New Zealand Expeditionary Force (2NZEF).
The Australian and New Zealand Army Corps (ANZAC) was originally a First World War army corps of the Mediterranean Expeditionary Force. It was formed in Egypt in December 1914, and operated during the Gallipoli campaign. General William Birdwood commanded the corps, which primarily consisted of troops from the First Australian Imperial Force and 1st New Zealand Expeditionary Force, although there were also British and Indian units attached at times throughout the campaign. The corps disbanded in 1916, following the Allied evacuation of the Gallipoli peninsula and the formation of I ANZAC Corps and II ANZAC Corps. The corps was reestablished, briefly, in the Second World War during the Battle of Greece in 1941. The term 'ANZAC' has been used since for joint Australian–New Zealand units of different sizes.
The Sinai and Palestine campaign was part of the Middle Eastern theatre of World War I, taking place between January 1915 and October 1918. The British Empire, the French Third Republic, and the Kingdom of Italy fought alongside the Arab Revolt in opposition to the Ottoman Empire, the German Empire, and the Austro-Hungarian Empire. It started with an Ottoman attempt at raiding the Suez Canal in 1915 and ended with the Armistice of Mudros in 1918, leading to the cession of Ottoman Syria.
The Entente, or the Allies, were an international military coalition of countries led by France, the United Kingdom, Russia, the United States, Italy, and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria in World War I (1914–1918).
The Egyptian Expeditionary Force (EEF) was a British Empire military formation, formed on 10 March 1916 under the command of General Archibald Murray from the Mediterranean Expeditionary Force and the Force in Egypt (1914–15), at the beginning of the Sinai and Palestine Campaign of the First World War.
General Sir Alexander John Godley, was a senior British Army officer. He is best known for his role as commander of the New Zealand Expeditionary Force and II Anzac Corps during the First World War.
The South African Overseas Expeditionary Force (SAOEF) was a volunteer military organisation in World War I.
Expeditionary warfare is a military invasion of a foreign territory, especially away from established bases. Expeditionary forces were in part the antecedent of the modern concept of rapid deployment forces. Traditionally, expeditionary forces were essentially self-sustaining with an organic logistics capability and with a full array of supporting arms.
The Allied leaders of World War I were the political and military figures that fought for or supported the Allied Powers during World War I.
The use of horses in World War I marked a transitional period in the evolution of armed conflict. Cavalry units were initially considered essential offensive elements of a military force, but over the course of the war, the vulnerability of horses to modern machine gun, mortar, and artillery fire reduced their utility on the battlefield. This paralleled the development of tanks, which ultimately replaced cavalry in shock tactics. While the perceived value of the horse in war changed dramatically, horses still played a significant role throughout the war.
Conflicts took place in North Africa during World War I (1914–1918) between the Central Powers and the Entente and its allies. The Senussi of Libya sided with the Ottoman Empire and the German Empire against the British Empire and the Kingdom of Italy. On 14 November 1914, the Ottoman Sultan proclaimed a jihad and sought to create a diversion to draw British troops from the Sinai and Palestine Campaign. Italy wished to preserve its gains from the Italo-Turkish War. The Senussi Campaign took place in North Africa from 23 November 1915 to February 1917.
Military aircraft insignia are insignia applied to military aircraft to identify the nation or branch of military service to which the aircraft belong. Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time.
The Belgian Expeditionary Corps of Armoured Cars in Russia was a Belgian military unit sent to Russia during World War I. It fought alongside the Imperial Russian army on the Eastern Front. Between 1915 and 1918, 444 Belgian soldiers served with the unit of whom 16 were killed in action.
General Officers of World War I is an oil painting by John Singer Sargent, completed in 1922. It was commissioned by South African financier Sir Abraham Bailey, 1st Baronet to commemorate the generals who commanded British and British Empire armies in the First World War.
The Australian Army was the largest service in the Australian military during World War I. The First Australian Imperial Force (AIF) was the Army's main expeditionary force and was formed from 15 August 1914 with an initial strength of 20,000 men, following Britain's declaration of war on Germany. Meanwhile, the separate, hastily raised 2,000-man Australian Naval and Military Expeditionary Force (AN&MEF), landed near Rabaul in German New Guinea on 11 September 1914 and obtained the surrender of the German garrison after ten days; it later provided occupation forces for the duration of the war. In addition, small military forces based on the pre-war Permanent Forces and part-time Citizen Forces were maintained in Australia to defend the country from attack.
