The Warwickshire Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Warwickshire in 1908. It was the first Territorial Force artillery unit to go overseas on active service, spending the whole of the First World War on the Western Front, mostly with 1st Cavalry Division and 29th Division. A second line battery, 2/1st Warwickshire RHA, also 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.
History
Formation
The Territorial Force (TF) was formed on 1 April 1908 following the enactment of the Territorial and Reserve Forces Act 1907 (7 Edw.7, c.9) which combined and re-organised the old Volunteer Force, the Honourable Artillery Company and the Yeomanry. On formation, the TF contained 14 infantry divisions and 14 mounted yeomanry brigades. Each yeomanry brigade included a horse artillery battery and an ammunition column.
On 18 March 1908, Warwickshire Royal Horse Artillery (Territorial Force) was proposed as a new unit and it was recognized by the Army Council on 4 June 1908. The battery was raised by Lord Brooke at Warwick Castle. It consisted of Battery HQ at Leamington Warwickshire Battery at Leamington 1st South Midland Mounted Brigade Ammunition Column also at Leamington The battery was equipped with four Ehrhardt 15-pounder guns and allocated as artillery support to the 1st South Midland Mounted Brigade.
First World War
In accordance with the Territorial and Reserve Forces Act 1907 (7 Edw.7, c.9) which brought the Territorial Force into being, the TF was intended to be a home defence force for service during wartime and members could not be compelled to serve outside the country. However, on the outbreak of war on 4 August 1914, many members volunteered for Imperial Service. Therefore, TF units were split into 1st Line (liable for overseas service) and 2nd Line (home service for those unable or unwilling to serve overseas) units. 2nd Line units performed the home defence role, although in fact most of these were also posted abroad in due course.
1/1st Warwickshire
The 1st Line battery was embodied with the 1st South Midland Mounted Brigade on 4 August 1914 at the outbreak of the First World War. Initially, the brigade moved to Diss, Norfolk and joined the 1st Mounted Division. Later in August, a concentration of mounted brigades was ordered to take place around the Churn area of Berkshire and the brigade moved to the racecourse at Newbury. These brigades were transferred to the new 2nd Mounted Division on 2 September. I Brigade RHA and II Brigade RHA were formed for the division and the battery was assigned to I Brigade at Churn.
At the end of October 1914, B Battery, Honourable Artillery Company replaced it in I Brigade and the Warwickshire Battery departed for France, landing at Le Havre on 1 November. It was therefore the first Territorial Force artillery unit to go overseas on active service. The 42nd (East Lancashire) Division had departed for Egypt from 10 September 1914, the 43rd (Wessex) Division for India on 9 October, and the 44th (Home Counties) Division also for India on 30 October, complete with their artillery batteries. However, these divisions were to act as garrison forces and neither Egypt nor India was a theatre of war at this time: on arrival in India, the units reverted to peace-time conditions and pushed on with training to prepare for field service, and Britain did not declare war on Turkey until 5 November 1914.
Warwickshire RHA was to spend the rest of the war on the Western Front. Initially held up by horse sickness, it was not until 4 December that the battery was attached to the 2nd Cavalry Division. On 14 April 1915 it joined VII Brigade RHA, 1st Cavalry Division and was assigned to 9th Cavalry Brigade While with 1st Cavalry Division, the division took part in the Second Battle of Ypres, notably the Battle of Frezenberg Ridge (913 May) and the Battle of Bellewaarde Ridge (24 May 1915), and the Battle of Flers–Courcelette (15 September 1916) as part of the Battle of the Somme.
On 23 August 1915, the battery was re-equipped, not with the expected 13 pounders but with four 18 pounders, normally employed by Royal Field Artillery batteries to support infantry. On 21 November 1916, the battery joined XV Brigade RHA, 29th Division in exchange for the regular Y Battery RHA.
