The pre-war Territorial Force infantry divisions were generally[a] supported by four field artillery brigades.

[3] When the 52nd (Lowland) Division was ordered to Gallipoli in May 1915, it left two of its field artillery brigades behind in the UK on the Forth Defences.

(1st and 2nd Edinburgh and Midlothian Batteries and Brigade Ammunition Column) proceeded to France in October 1915 where it was re-equipped with 18 pounders and joined 51st (Highland) Division.

It consisted of the Essex, Hampshire and West Riding RHA Batteries and a Brigade Ammunition Column (BAC).

[12][d] The brigade (with the Hampshire Battery) joined the Yeomanry Mounted Division at Khan Yunis on 5 July.

[5] Essex Battery, RHA remained with 52nd (Lowland) Division until 17 September 1917 when it joined 7th Mounted Brigade which had returned to Egypt from Salonika on 29 June.

Likewise, Leicestershire, RHA (also four 13 pounders) transferred from ANZAC Mounted Division on 20 June 1916 and joined the brigade on 5 July 1917.

[16] Once the division was restructured and renamed, it served with the DMC for the rest of the war, taking part in the Second Transjordan Raid (30 April to 4 May 1918) and the Final Offensive, in particular the Battle of Megiddo (19 to 25 September) and the Capture of Damascus (1 October).
