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).
Australian Light Horse were mounted troops with characteristics of both cavalry and mounted infantry, who served in the Second Boer War and World War I. During the inter-war years, a number of regiments were raised as part of Australia's part-time military force. These units were gradually mechanised either before or during World War II, although only a small number undertook operational service during the war. A number of Australian light horse units are still in existence today.
The First Australian Imperial Force was the main expeditionary force of the Australian Army during the First World War. It was formed as the Australian Imperial Force (AIF) following Britain's declaration of war on Germany on 15 August 1914, with an initial strength of one infantry division and one light horse brigade. The infantry division subsequently fought at Gallipoli between April and December 1915, with a newly raised second division, as well as three light horse brigades, reinforcing the committed units.
The Australian 4th Division was formed in the First World War during the expansion of the Australian Imperial Force (AIF) infantry brigades in February 1916. In addition to the experienced 4th Brigade were added the new 12th and 13th Brigades. From Egypt the division was sent to France, where it took part in the fighting on the Western Front during 1916–1918. After the war ended, the AIF was demobilised and the division was dissolved.
The New Zealand and Australian Division was a composite army division raised for service in the First World War under the command of Major General Alexander Godley. Consisting of several mounted and standard infantry brigades from both New Zealand and Australia, it served in the Gallipoli Campaign between April and December 1915.
The I ANZAC Corps was a combined Australian and New Zealand army corps that served during World War I.
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, 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, ordnance workshops, medical and dental units, transport, salvage and an employment company.
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.
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.
In Australia, the outbreak of World War I was greeted with considerable enthusiasm. Even before Britain declared war on Germany on 4 August 1914, the nation pledged its support alongside other states of the British Empire and almost immediately began preparations to send forces overseas to engage in the conflict. The first campaign that Australians were involved in was in German New Guinea after a hastily raised force known as the Australian Naval and Military Expeditionary Force was dispatched in September 1914 from Australia and seized and held German possessions in the Pacific. At the same time another expeditionary force, initially consisting of 20,000 men and known as the First Australian Imperial Force (AIF), was raised for service overseas.
The 1st Light Horse Brigade was a mounted infantry brigade of the Australian Imperial Force (AIF), which served in the Middle Eastern theatre of World War I. The brigade was initially formed as a part-time militia formation in the early 1900s in New South Wales and then later in Queensland. In 1914, the brigade was re-constituted as part of the AIF and was sent to Egypt. Forming part of the New Zealand and Australian Division, during the Gallipoli Campaign it served in a dismounted role between May and December 1915. After being withdrawn to Egypt it served in the Anzac Mounted Division from March 1916 as part of the Egyptian Expeditionary Force, taking part in the Sinai and Palestine Campaign until the end of the war. It was disbanded in 1919. After the war, the AIF light horse regiments were demobilised and disbanded; however, the brigade briefly existed as a part-time militia formation in Queensland until 1921 when its regiments were reorganised into cavalry brigades.
The 2nd Light Horse Brigade was a mounted infantry brigade of the Australian Imperial Force (AIF) which served in the Middle Eastern theatre of World War I. The brigade was initially formed as a part-time militia formation in the early 1900s in New South Wales. In 1914, the brigade was re-constituted as part of the AIF. The brigade first saw action while serving in the Australian and New Zealand Army Corps (ANZAC) during the Gallipoli campaign. After being withdrawn to Egypt in February 1916 they served in the ANZAC Mounted Division from March 1916 as part of the Egyptian Expeditionary Force during the Sinai and Palestine Campaign until the end of the war. After the war, the AIF light horse regiments were demobilised and disbanded; however, the brigade briefly existed as a part-time militia formation in New South Wales until 1921 when its regiments were reorganised into cavalry brigades.
The 3rd Light Horse Brigade was a mounted infantry brigade of the Australian Imperial Force (AIF), which served in the Middle Eastern theatre of World War I. The brigade was initially formed as a part-time militia formation in the early 1900s in Victoria. In 1914, the brigade was re-constituted as part of the AIF. The brigade first saw action while serving with the Australian and New Zealand Army Corps during the Gallipoli campaign where they were noted for their attack during the Battle of the Nek. After being withdrawn to Egypt in February 1916 they were involved in the Sinai and Palestine Campaign until the end of the war. They were attached to a number of different formations being part of the Anzac Mounted Division in March 1916 and the Australian Mounted Division in June 1917, who they remained with until the end of the war. After the war, the AIF light horse regiments were demobilised and disbanded; however, the brigade briefly existed as a part-time militia formation in New South Wales until 1921 when its regiments were reorganised into cavalry brigades.
The 4th Light Horse Regiment was a mounted infantry regiment of the Australian Army during the First World War. The regiment was raised in August 1914, as the divisional cavalry regiment for the 1st Division. The regiment fought against the forces of the German Empire and the Ottoman Empire, in Egypt, at Gallipoli, on the Western front, on the Sinai Peninsula, and in Palestine and Jordan. After the armistice the regiment eventually returned to Australia in March 1919. For its role in the war the regiment was awarded twenty-one battle honours.
The 13th Light Horse Regiment was a mounted infantry regiment of the Australian Army during the First World War. The regiment was raised in March 1915, and eventually assigned as the mounted regiment for the Australian Corps. During the war the regiment fought against the forces of the Ottoman Empire, at Gallipoli, and against the German Empire on the Western Front. For its role in the war the regiment was awarded twelve battle honours. In 1921, it was later re-raised as a part-time unit of the Citizens Forces, and was briefly amalgamated with the 19th Light Horse. During the Second World War, the regiment was converted into an armoured regiment, designated the "13th Armoured Regiment", although it was disbanded in late 1943 without seeing action.
The acronym ANZAC came from the Australian and New Zealand Army Corps, formed in Egypt prior to the Gallipoli Campaign during the First World War. The corps was the higher formation for all Australian and New Zealand soldiers. It then gave its name to ANZAC Cove, on the Gallipoli peninsula, and at first was only used to identify the men who took part in the Gallipoli landings, although it later came to mean "any Australian or New Zealand soldier of the First World War." Both the 'ANZAC' and the 'Anzac' versions of the acronym have been protected by the Commonwealth Government of Australia.
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.
The Australian Cycling Corps was formed in Egypt in 1916 as part of the Australian Imperial Force (AIF), and fought on the Western Front in France and Belgium during World War I. They were used mainly as despatch riders, while also conducting reconnaissance and patrolling. It was disbanded in 1919.
The II ANZAC Corps Mounted Regiment was a combined mounted unit made up of Australian and New Zealand troops during the First World War. The regiment served on the Western Front between 1916 and 1918. For the most part, the regiment undertook rear area duties, although it undertook more mobile operations in early 1917 during the German withdrawal to the Hindenburg Line. In November 1917, the regiment was redesignated as the XXII Corps Mounted Regiment when II ANZAC Corps was converted into XXII Corps. During early 1918, the regiment played a defensive role during the German spring offensive and then supported French operations during the Second Battle of the Marne. The regiment continued operations throughout the remainder of 1918, supporting the Allied Hundred Days Offensive until the end of the war.
The New Zealand Cyclist Corps was an administrative corps of the New Zealand Military Forces during the First World War. It was formed in April 1916, initially as a single company, but by 1918 had been expanded to a battalion of three companies. The cyclists saw action on the Western Front, but were controlled at corps level and generally did not fight with the New Zealand Division. The New Zealand Cyclist Corps was disbanded at the end of the war.
