SAAF fighter, bomber, and reconnaissance squadrons played a key role in the Western Desert and North African campaigns from 1941 to 1943. One memorable feat was the Boston bombers of 12 and 24 Squadrons dropping hundreds of tons of bombs on Axis forces pushing the Eighth Army back towards Egypt during the "Gazala Gallop" in mid-1942. SAAF bombers continually harassed retreating forces towards the Tunisian border after the Second Battle of El Alamein; the South African fighters of No. 223 Wing RAF helped the Desert Air Force gain air superiority over Axis air forces. Between April 1941 and May 1943, the eleven SAAF squadrons flew 33,991 sorties and destroyed 342 enemy aircraft.
