B Battery (2nd City of London Horse Artillery), Honourable Artillery Company was a horse artillery battery that was formed from the Field Artillery, HAC in 1899. It transferred to the Territorial Force in 1908 as artillery support for the South Eastern Mounted Brigade.
It saw active service during the First World War in the Middle East, notably at Aden and in particular in the Sinai and Palestine Campaign, from 1915 to 1918.
The second line battery – 2/B 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 – B (Reserve) Battery, HAC – was formed in 1915 to provide trained replacements for the 1st and 2nd Line batteries.
Post war, the battery, along with A 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.
