1935, it was converted from infantry to the searchlight role as the 32nd (7th City of London) Anti-aircraft Battalion, Royal Engineers, and the 'Post Office Rifles' name was finally dropped. In 1939 they expanded from Finsbury Square, into newly built drill-halls at Grove Park and Bexleyheath. Shortly afterward the unit was split, forming a duplicate battalion at Bexleyheath called 73rd (Kent Fortress) S/Light Battalion, Royal Engineers, with outstations at Greenhithe and Sidcup. In 1940 both units re-badged as Royal Artillery. Successor units still occupy Grove Park and Bexleyheath drill-halls, as 265 (Home Counties) Battery, 106th (Yeomanry) Regiment, Royal Artillery and 265 (Kent and County of London Yeomanry) Support Squadron, Royal Corps of Signals. Both units strive to continue and maintain the traditions and history of their predecessor regiments. Memorials to the Post Office Rifles Memorials to the Post Office Rifles can be found at Paignton War Memorial, at St. Lawrence Parish Church, Abbots Langley, and on a plaque outside the Uckfield village church. A First World War Book of Remembrance is sited in St Botolph Aldersgate EC1, the church traditionally associated with the unit, whilst a Second World War regimental memorial plaque is displayed within the Army Reserve Centre in Grove Park, London. There is no formal memorial to the Rifles in France, but many of the fallen from the Great War have their names recorded on memorials such as the Menin Gate at Ypres and Sir Edwin Lutyens's memorial to the missing at Thiepval. Also on the Pozieres Memorial to the missing of 1918 and notably the Arras memorial. Men of the Rifles are buried in Bedford House Cemetery outside Ypres (Ieper) in Belgium.
