During the early days World War II, the airfield was abandoned as the RAF moved its units to RAF Habbaniya during the 1941 Iraqi coup d'état and subsequent Anglo-Iraqi War. It may have been used by some German Luftwaffe units that had moved in from Vichy French controlled Syria, during an attempted coups by German-leaning Iraqi Generals who had engineered a coup in Iraq on 31 March 1941. However, the British moved in both land reinforcements from BritishPalestine and flew in some Wellington and Blenheim bombers to RAF Habbaniya. The coup crumbled in disorder, with the pro-Nazi forces in Iraq surrendering on 30 May. The Luftwaffe units stranded in Iraq retreated back to Syria. Outnumbered at least three to one, using outmoded equipment and facing the best of Nazi Germany's air power, the British still managed to conquer Iraq in less than four weeks. It was the first time the Luftwaffe had been beaten in World War II.
