Russian port in eastern Siberia. Seized from the Bolsheviks by troops of the Czech Legion on 29 June 1918, Vladivostok was also home to 600,000 tons of Allied war supplies for the now defunct Imperial Russian army. Largely to prevent these supplies falling into German hands after Russia left the war, Allied forces - primarily 70,000 Japanese and 9,000 American troops - occupied Vladivostok and declared it an 'Allied Protectorate' on 6 July 1918. Half-hearted attempts were subsequently made to support the counter-revolutionary forces in the region under General Kolchak; then Allied forces began to withdraw from Vladivostok in the autumn of 1919.
