In May 1944 No. 77 Squadron posted to the newly opened nearby RAF Full Sutton and was replaced at Elvington by two French squadrons, numbers 346 "Guyenne" and 347 "Tunisie" who both played a leading part in the bombing of Germany. Elvington was the only airfield in the United Kingdom used by the remainder of the Free French Forces, they also flew Handley Page Halifax heavy bombers until they moved to Bordeaux in October 1945 where they became the basis for the new air force of liberated France. In September 1957 a memorial was unveiled in Elvington village dedicated to the two French squadrons. While they were at RAF Elvington nearly half of the squadrons' members were killed.
