The
North Russia Intervention, also known as the
Northern Russian Expedition, the
Archangel Campaign, and the
Murman Deployment, was part of the
Allied Intervention in Russia after the
October Revolution. The intervention brought about the involvement of foreign troops in the
Russian Civil War on the side of the
White movement. While the movement was ultimately defeated, the Allied forces fought notable ending defensive actions against the Bolsheviks in the battles of
Bolshie Ozerki and
Romanovka, allowing them to withdraw from Russia in good order. The campaign lasted from 1918, during the final months of
World War I, to 1920.
