Allied intervention in the Russian Civil War
Allied intervention in the Russian Civil War consisted of a series of multi-national military expeditions which began in 1918. The Allies first had the goal of helping the Czechoslovak Legion in securing supplies of munitions and armaments in Russian ports. At times between 1918 and 1920 the Czechoslovak Legion controlled the entire Trans-Siberian Railway and several major cities in Siberia. By 1919 the goal was to help the White forces in the Russian Civil War. When the Whites collapsed the forces were withdrawn by 1920 (or 1922 in the case of Japan). The Soviet government until its collapse in 1991 made the episode a feature of its anti-Western propaganda.
