The British Expeditionary Force (BEF) was the British Army sent to the Western Front during the First World War. Planning for a British Expeditionary Force began with the 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 Territorial Force was a part-time volunteer component of the British Army, created in 1908 to augment British land forces without resorting to conscription. The new organisation consolidated the 19th-century Volunteer Force and yeomanry into a unified auxiliary, commanded by the War Office and administered by local County Territorial Associations. The Territorial Force was designed to reinforce the regular army in expeditionary operations abroad, but because of political opposition it was assigned to home defence. Members were liable for service anywhere in the UK and could not be compelled to serve overseas. In the first two months of the First World War, territorials volunteered for foreign service in significant numbers, allowing territorial units to be deployed abroad. They saw their first action on the Western Front during the initial German offensive of 1914, and the force filled the gap between the near destruction of the regular army that year and the arrival of the New Army in 1915. Territorial units were deployed to Gallipoli in 1915 and, following the failure of that campaign, provided the bulk of the British contribution to allied forces in the Sinai and Palestine Campaign. By the war's end, the Territorial Force had fielded twenty-three infantry divisions and two mounted divisions on foreign soil. It was demobilised after the war and reconstituted in 1921 as the Territorial Army.
The Indian Army (IA), often known since 1947 as the British Indian Army to distinguish it from the current Indian Army, was the principal military of the British Indian Empire before its decommissioning in 1947. It was responsible for the defence of both British Indian Empire and the princely states, which could also have their own armies. The Indian Army was an important part of the British Empire's forces, both in India and abroad, particularly during the First World War and the Second World War.
The 48th Division was an infantry division of the British Army. Part of the Territorial Force (TF) and raised in 1908, the division was originally called the South Midland Division, and was redesignated as the 48th Division in 1915. During the First World War, the division saw service on the Western Front before being transferred to the Italian Front in November 1917 and remaining there for the rest of the war.
The Home Counties Division was an infantry division of the Territorial Force, part of the British Army, that was raised in 1908. As the name suggests, the division recruited in the Home Counties, particularly Kent, Middlesex, Surrey and Sussex.
The Ulster Volunteers was a unionist militia founded in 1912 to block domestic self-government for Ireland, which was then part of the United Kingdom. The Ulster Volunteers were based in the northern province of Ulster. Many Ulster Protestants feared being governed by a Catholic-majority parliament in Dublin and losing their local governance and strong links with Great Britain. In 1913, the militias were organised into the Ulster Volunteer Force (UVF) and vowed to resist any attempts by the British Government to impose Home Rule on Ulster. Later that year, Irish nationalists formed a rival militia, the Irish Volunteers, to safeguard Home Rule. In April 1914, the UVF smuggled 25,000 rifles into Ulster. The Home Rule Crisis was halted by the outbreak of World War I in August 1914. Many UVF members enlisted with the British Army's 36th (Ulster) Division and went to fight on the Western Front.
The 1st Mounted Division was a Yeomanry Division of the British Army active during World War I. It was formed in August 1914 for the home defence of the United Kingdom from four existing mounted brigades of the Territorial Force, each of three regiments of Yeomanry. The divisional order of battle changed often, as the 1st Line brigades left for service overseas and were replaced by 2nd Line formations. It was converted to the 1st Cyclist Division in July 1916, and was broken up in November 1916 without being involved in active service. It remained in East Anglia throughout its existence.
The Lincolnshire Yeomanry was a volunteer cavalry unit of the British Army formed in 1794. It saw action in the Second Boer War and the First World War before being disbanded in 1920.
The Haldane Reforms were a series of far-ranging reforms of the British Army made from 1906 to 1912, and named after the Secretary of State for War, Richard Burdon Haldane. They were the first major reforms since the "Childers Reforms" of the early 1880s, and were made in the light of lessons newly learned in the Second Boer War.
The 4th Mounted Division was a short-lived Yeomanry Division of the British Army active during World War I. It was formed on 20 March 1916, converted to 2nd Cyclist Division in July 1916 and broken up on 16 November 1916. It remained in England on Home Defence duties throughout its existence.
The 63rd Division of the British Army was a second-line Territorial Force division, formed in 1914, which served on home defence duties during the First World War. The division was formed as a duplicate of the 50th (Northumbrian) Division in 1914, composed primarily of soldiers recruited in north-eastern England. It remained on home defence and training duties in the north-east and east of England until 1916, when it was disbanded. Several of its constituent units would later serve overseas, deployed for support and garrison duties in almost every theatre of the war.
The 64th Division was an infantry division of the British Army, raised during the Great War. The division was formed in late 1914 as a second-line Territorial Force formation which served on home defence duties throughout the war.
The Hampshire Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Hampshire in 1909. It saw active service during the First World War in Egypt and Palestine from 1916 to 1918, initially as field artillery with 52nd (Lowland) Division before being converted back to horse artillery and serving with the Yeomanry Mounted Division and 1st Mounted / 4th Cavalry Division. A second line battery, 2/1st Hampshire RHA, served on the Western Front in 1917 and 1918 as part of an Army Field Artillery Brigade. Post-war, it was reconstituted as a Royal Field Artillery battery.
The Inverness-shire Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Inverness-shire in 1908. It saw active service during the First World War in the Sinai and Palestine Campaign with the ANZAC Mounted Division from 1916 to 1918. A second line battery, 2/1st Inverness-shire RHA, served in the United Kingdom throughout the war. It was disembodied after the end of the war and was reconstituted as a Royal Field Artillery battery in 1920.
The Somerset Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Somerset in 1908. It saw active service during the First World War in the Sinai and Palestine Campaign with the ANZAC Mounted Division from 1916 to 1918. A second line battery, 2/1st Somerset RHA, served on the Western Front with the 63rd Division from 1916 to 1918. It was disembodied after the end of the war and was not reconstituted in the Territorial Force in 1920.
The Shropshire Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Shropshire in 1908 from the Shropshire Battery of the 1st Shropshire and Staffordshire Artillery Volunteers, Royal Garrison Artillery of the Volunteer Force. It saw active service during the First World War on the Western Front in 1917 and 1918 as part of an Army Field Artillery Brigade. A second line battery, 2/1st Shropshire RHA, also served on the Western Front in 1917 and 1918 as part of another Army Field Artillery Brigade. It was reconstituted post-war as a medium artillery battery and served as such in the Second World War.
The 2nd Home Counties Division was a 2nd Line Territorial Force division of the British Army in World War I. The division was formed as a duplicate of the 44th Division in November 1914. As the name suggests, the division recruited in the Home Counties, particularly Kent, Middlesex, Surrey and Sussex. In August 1915, in common with all Territorial Force divisions, it was numbered as 67th Division. Between September 1917 and the end of the year, the division was extensively reorganized and lost its territorial identity; henceforth it was known as 67th Division.
The 2nd Welsh Division was a 2nd Line Territorial Force division of the British Army in the First World War. The division was formed as a duplicate of the 53rd (Welsh) Division in January 1915. As the name suggests, the division recruited in Wales, but also included units from Cheshire and Herefordshire in England. In August 1915, in common with all Territorial Force divisions, it was numbered as 68th Division. During the winter of 1917–18, the division was extensively reorganized and lost its territorial identity; henceforth it was known as 68th Division.
The 2nd East Anglian Division was a 2nd Line Territorial Force division of the British Army in World War I. The division was formed as a duplicate of the 54th Division in November 1914. As the name suggests, the division recruited in East Anglia, particularly Essex, Norfolk, and Suffolk, but also Bedfordshire, Cambridgeshire, Hertfordshire, and Northamptonshire. In August 1915, in common with all Territorial Force divisions, it was numbered as 69th Division. By January 1918 it had been extensively reorganized and lost its territorial identity; henceforth it was known as 69th Division.
