The Murmansk Legion, also known as the Finnish Legion, was a British Royal Navy organized military unit during the 1918–1919 Allied North Russia Intervention. It was composed of Finnish Red Guards who had fled after the Finnish Civil War from the White-dominated Northern Finland to Soviet Russia and of some Finns working on the Murmansk Railroad. The Legion, along with British troops, fought off the 1918 Viena expedition of Finnish White Guards and defended the Murmansk Railroad.
