In 1941, Estonians were conscripted into the 8th Estonian Rifle Corps and in 1941–1944 to the Nazi German forces. Men who avoided these mobilisations fled to Finland to be formed into the Finnish Infantry Regiment 200. About 40% of the Estonian pre-war fleet was requisitioned by British authorities and used in Atlantic convoys. Approximately 1000 Estonian sailors served in the British Merchant Navy, 200 of them as officers. A small number of Estonians served in the Royal Air Force, in the British Army and in the U.S. Army.
