A (1st City of London) Battery, Honourable Artillery Company is a L118 light gun battery that provides a reserve to 7th Parachute Regiment Royal Horse Artillery.[1] Its predecessor was a horse artillery battery that was formed from Light Cavalry Squadron, HAC, in 1891. It transferred to the Territorial Force in 1908 as artillery support for the London Mounted Brigade.
During the First World War it was posted to Egypt in 1915, served as part of the Western Frontier Force in the Senussi Campaign in 1916 and in the Sinai and Palestine Campaign with the Imperial (later Australian) Mounted Division in 1917 and 1918. The second line battery – 2/A Battery, HAC – was formed in 1914 and served on the Western Front in 1917 and 1918 as part of an Army Field Artillery Brigade; the third line – A (Reserve) Battery, HAC – was formed in 1915 to provide trained replacements for the 1st and 2nd Line batteries.
Post-war, the battery, along with B Battery, Honourable Artillery Company, was amalgamated with the City of London Yeomanry (Rough Riders) to form the 11th (Honourable Artillery Company and City of London Yeomanry) Brigade, RHA.
