 The Whites were bolstered when 35,000 members of the Czech Legion—prisoners of war from the conflict with the Central Powers—turned against Sovnarkom and allied with the Committee of Members of the Constituent Assembly (Komuch), an anti-Bolshevik government established in Samara.The Whites were also backed by Western governments who perceived the Treaty of Brest-Litovsk as a betrayal of the Allied war effort and feared the Bolsheviks' calls for world revolution.In 1918, the United Kingdom, France, United States, Canada, Italy, and Serbia landed 10,000 troops in Murmansk, seizing Kandalaksha, while later that year British, American, and Japanese forces landed in Vladivostok.
