During the October Revolution the sailors of the Baltic Fleet (renamed "Naval Forces of the Baltic Sea" in March 1918) were among the most ardent supporters of Bolsheviks, and formed an elite among Red military forces. The fleet was forced to evacuate several of its bases after Russia's withdrawal from the First World War, under the terms of the Treaty of Brest-Litovsk. The "Ice Cruise" of the Baltic Fleet (1918), led by Alexey Schastny, saw the evacuation of most of the fleet's ships to Kronstadt and Petrograd.
