Canadian Siberian Expeditionary Force

The Canadian Siberian Expeditionary Force (also referred to as the Canadian Expeditionary Force (Siberia) or simply C.S.E.F.) was a Canadian military force sent to Vladivostok, Russia during the Russian Revolution to bolster the allied presence. Composed of 4,192 soldiers and authorised in August 1918, the force returned to Canada between April and June 1919. The force was commanded by Major General James H. Elmsley. During this time, the C.S.E.F. saw little fighting, with fewer than 100 troop proceeding "up country" to Omsk, to serve as administrative staff for 1,500 British troops aiding the White Russian government of Admiral Alexander Kolchak. Most Canadians remained in Vladivostok, undertaking routine drill and policing duties in the volatile port city.

The Marine Cemetery in Vladivostok, a Commonwealth War Graves Commission site, contains the graves of 14 Canadians alongside British, French, Czecho-Slovak and Japanese troops who died during the Siberian Intervention and a monument to Allied soldiers buried in various locations in Siberia. The Commonwealth portion of the cemetery was neglected during the Soviet era; a Canadian naval vessel restored the cemetery in the 1990s. In 1996 a Canadian squadron of warships visited Vladivostok. During the visit sailors from HMCS Protecteur assisted by members of the Russian Navy, replaced headstones and generally repaired the graves of Canadians buried in a local cemetery.
