Siberian Intervention

Americans drawn largely from units trained on the West Coast landed in Vladivostok in the summer and fall of 1918. There they joined British and Commonwealth troops, the Czechoslovak Legion and various other foreign contingents, including some 70,000 Japanese. Tokyo meant to use the chaos in Russia to seize as much of Siberia and the Russian islands off its coast as possible, not to mention a large bite of Manchuria.
