On 30 April, the Iraqi Army surrounded and besieged RAF Habbaniya; the base had no operational aircraft but the RAF converted trainers to carry weapons and a battalion of infantry reinforcements was flown in. German and Italian aircraft supported the Iraqi army and British reinforcements were dispatched to Iraq from Transjordan and India. The larger but poorly trained Iraqi force was defeated and Baghdad and Mosul were captured. Ali and his supporters fled the country and an armistice was signed, restoring the monarchy of Faisal II, the Kingdom of Iraq and a pro-British government. The defeat of the rebellion saw the defeat of the German-Italian attempt to entrench an Axis state in Iraq and worsened relations between the UK and Vichy France, culminating in the Syria-Lebanon Campaign.
