The City of London Yeomanry (Rough Riders) was a yeomanry regiment of the British Territorial Army, formed in 1901 from veterans of the Second Boer War. In the First World War it served dismounted in the Gallipoli Campaign but reverted to the mounted role in the Senussi campaign, at Salonika and in Palestine. It ended the war as a machine gun unit on the Western Front. In the interwar years it was reduced to a battery in a composite Royal Horse Artillery unit in London, but in the period of rearmament before the Second World War it was expanded into a full regiment of light anti-aircraft artillery. It served in this role during The Blitz and later in the Tunisian and Italian campaigns. Postwar it became an armoured regiment. It amalgamated with the Inns of Court Regiment to form the Inns of Court & City Yeomanry in 1961. The lineage is maintained by 68 (Inns of Court & City Yeomanry) Signal Squadron, part of 71 (Yeomanry) Signal Regiment.
