How a 1941 coup in Iraq forced a desperate British military response
When Iraqi nationalists seized power in 1941, they threatened vital British oil interests and supply lines to India. Despite being outnumbered and ill-equipped, a small British garrison at RAF Habbaniya faced down thousands of Iraqi troops, triggering a conflict that would reshape Middle Eastern influence during the Second World War.
The Anglo-Iraqi War was sparked by the April 1941 coup d'état led by Rashid Ali al-Gaylani and the Golden Square, a group of four senior military commanders. This nationalist government, supported by Nazi Germany and Fascist Italy, sought to curtail British influence, which had been entrenched since the 1930 Anglo-Iraqi Treaty. This treaty granted Britain control over Iraqi petroleum and allowed for the maintenance of military bases, including RAF Habbaniya and RAF Shaibah, which served as critical links between Egypt and India.
By late April 1941, tensions reached a breaking point. On 30 April, Iraqi forces surrounded RAF Habbaniya, occupying the surrounding plateau with thousands of troops and dozens of artillery pieces. Air Vice-Marshal Harry Smart, commanding the base, faced a precarious situation: he had only about 2,500 men, including Assyrian Levies and aircrew, to defend a facility housing 9,000 civilians. The base was dominated by Iraqi artillery, leaving it vulnerable to a single strike on its water or power infrastructure.
Despite the tactical disadvantage, British leadership in London remained resolute. Prime Minister Winston Churchill, viewing the Iraqi situation as a secondary priority compared to the Mediterranean, nonetheless authorized Ambassador Sir Kinahan Cornwallis to use all necessary force. On 2 May, following the Iraqi refusal to withdraw, the British launched air strikes against the plateau. This military campaign ultimately led to the collapse of al-Gaylani's government, the restoration of the pro-British Regent, Prince 'Abd al-Ilah, and the solidification of Allied control in the region.
The conflict highlighted the strategic importance of Iraq as a land bridge and oil source. While the British were initially preoccupied with the Western Desert and Greek campaigns, the threat posed by the pro-Axis government necessitated a swift intervention. By mid-April, British forces had begun landing at Basra, and the subsequent air campaign from Habbaniya effectively neutralized the nationalist threat, ensuring that Iraq remained within the Allied sphere of influence for the remainder of the war.
