The Czechoslovak Legions had been part of the Russian Army and numbered around 30,000 troops by October 1917. They had an agreement with the new Bolshevik government to be evacuated from the Eastern Front via the port of Vladivostok to France. The transport from the Eastern Front to Vladivostok slowed down in the chaos, and the troops became dispersed all along the Trans-Siberian Railway. Under pressure from the Central Powers, Trotsky ordered the disarming and arrest of the legionaries, which created tensions with the Bolsheviks.
