The Fairey Battle was used on operations early in the Second World War. During the "Phoney War" the type achieved the distinction of scoring the first aerial victory of an RAF aircraft in the conflict. In May 1940, the Battles of the Advanced Air Striking Force suffered many losses, frequently in excess of 50 per cent of aircraft sorties per mission. By the end of 1940 the type had been withdrawn from front-line service and relegated to training units overseas. As an aircraft that had been considered to hold great promise in the pre-war era, the Battle proved to be one of the most disappointing aircraft in RAF service.
