Question

I would like to know more about the first world war, especially about the involvement of the USA on the eastern front. Were there any US troops in eastern front present, if so how many? Thanks in advance

Answer 1

There were no US troops involved in the Eastern Front of WWI, but they were involved in two campaigns of the Allied intervention in the Russian Civil War.

In the north of Russia, the US Army staged what is known as the Polar Bear Expedition, supported by the USN cruiser USS Olympia.

In the far east of Russia, the American Expeditionary Force, Siberia operated around Vladivostok, but did not fight the Bolsheviks.
