41st Siege Battery, was a heavy howitzer unit of the Royal Garrison Artillery (RGA) formed at Plymouth, during World War I. Half its personnel were Regular Army gunners returned from colonial garrisons in Asia, the remainder were Territorials from County Durham. It saw active service on the Western Front at the Battle of the Somme, where it suffered heavy casualties, at Vimy Ridge, Messines (where it again sustained heavy casualties) and Ypres. Several of its guns were overrun in the fighting against the German Spring Offensive, but it was refitted and participated in the Allies' final Hundred Days Offensive. It remained in the Regular Army after the war until it was absorbed into another unit in 1920.
