46th Siege Battery was a heavy howitzer unit of Britain's Royal Garrison Artillery (RGA) in World War I, formed at Tynemouth with a nucleus of Territorial Force coastal gunners from Cornwall. It served on the Somme and the Ancre, at Arras and Hill 70, before going to Ypres during the battles of Autumn 1917. It then fought against the German Spring Offensive and participated in the final Allied Hundred Days Offensive. The battery was absorbed into the Regular Army after the war.
