The Canadian Siberian Expeditionary Force (French: Corps expéditionnaire sibérien) (also referred to as the Canadian Expeditionary Force (Siberia) or simply the C.S.E.F.) was a Canadian military force sent to Vladivostok, Russia, during the Russian Revolution to bolster the allied presence, oppose the Bolshevik Revolution and attempt to keep Russia in the fight against Germany. Composed of 4,192 soldiers and authorized 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 troops proceeding "up country" to Omsk, to serve as administrative staff for 1,500 British troops aiding the anti-Bolshevik White Russian government of Admiral Alexander Kolchak. Most Canadians remained in Vladivostok, undertaking routine drill and policing duties in the volatile port city.[1]
