The Territorial Force was established on 1 April 1908 as a volunteer auxiliary to the British Army. It was formed by the amalgamation of the former auxiliary institutions of the Volunteer Force and the yeomanry. Designed primarily as a home defence force, its members could not be compelled to serve overseas unless they volunteered to do so. On the outbreak of the First World War in 1914, many did. The first units were deployed piecemeal in support of the regular army as it defended against the opening German offensive in Belgium and France in 1914. The first territorial divisions to be deployed were used to free up imperial garrisons overseas, but in 1915 they began to be deployed to the front lines on the Western Front and at Gallipoli. The pre-war territorial divisions were numbered in May 1915 in order of their deployment. As they were deployed, second-line divisions were raised to replace them at home, and in 1916 these began to be deployed to combat zones. By the end of the war in 1918, the Territorial Force had provided 28 divisions and 14 mounted brigades. [1] [2] [3] [4]
The original mounted brigades were: [33]

The Australian Mounted Division originally formed as the Imperial Mounted Division in January 1917, was a mounted infantry, light horse and yeomanry division. The division was formed in Egypt, and along with the Anzac Mounted Division formed part of Desert Column, Egyptian Expeditionary Force in World War I. The division was originally made up of the Australian 3rd Light Horse Brigade, the reconstituted 4th Light Horse Brigade, and two British yeomanry brigades; the 5th Mounted Brigade and 6th Mounted Brigade.
The 2nd Mounted Division was a yeomanry division that served in the First World War. At the outbreak of war it was assigned to defence of the Norfolk coast. In March 1915 it formed a 2nd Line duplicate of itself, the 2/2nd Mounted Division. Leaving the 2/2nd on coastal defence, it then fought at Gallipoli from April to December 1915, under the command of Major General William Peyton, before being disbanded in January 1916.
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 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 1st North Riding Artillery Volunteers was a part-time unit formed in the North Riding of Yorkshire in 1860 in response to an invasion scare. The unit later became part of the Territorial Force and served on the Western Front during World War I, while their successors served as anti-aircraft gunners in World War II.
The British home army in the First World War served the dual purpose of defending the country against invasion and training reinforcements for the army overseas. Initial responsibility for defending the nation lay with the Territorial Force, a part-time auxiliary designed in 1908 as a means of expanding the army in a major foreign conflict but, as a result of political compromise, implemented as a home defence army. It was supported in this role by 42,000 regular army troops, primarily belonging to the Royal Garrison Artillery and the Royal Engineers. The 14 infantry divisions and 14 mounted brigades of the Territorial Force were mainly allocated either to the Local Force, stationed near the coast and tasked with disrupting an invasion at the point of landing, or the Central Force, a mobile element tasked with defeating the invading force as it marched on London. The Local Force was augmented by units of the Special Reserve and Extra Reserve, which were the third battalions of the regular army line infantry regiments established to recruit and train replacements for their regiments' two combat battalions. The home army was also largely responsible for guarding vulnerable points, such as the communications infrastructure, rail network and munitions works.
