Anglo‑Iraqi War (1941) The Anglo‑Iraqi War of May 1941 was a brief but strategically significant campaign during World War II in which United Kingdom forces intervened to overturn a pro‑Axis coup in Baghdad led by elements of the Iraqi Army and the nationalist group known as the Golden Square. The fighting involved coordinated operations by the British Indian Army, Royal Air Force, and Royal Navy and intersected with wider campaigns in the Middle East such as the Syria–Lebanon Campaign and the later Anglo‑Soviet invasion of Iran. The conflict reshaped regional alignments and secured British lines of communication to Persia and India.

Background and Causes

The political crisis in Iraq traced to the 1930s interplay among the Hashemite Kingdom of Iraq, pro‑British elites, and rising Arab nationalism influenced by figures like Rashid Ali al‑Gilani and officers of the Iraqi Army who formed the Golden Square, while external pressure from Nazi Germany and Italian diplomatic efforts sought to exploit anti‑British sentiment. Strategic concerns over oil fields in Kirkuk, the Abadan refinery in Persia, and the Basra port made the United Kingdom determined to retain air and naval bases such as Habbaniya and RAF Shaibah, especially after the Fall of France and the Battle of Britain heightened imperial vulnerability. The 1930 Anglo‑Iraqi Treaty and treaties with the League of Nations framed legal disputes, while personalities including Nuri al‑Said and exponents like Tawfiq al‑Saadi shaped factional alignments that culminated in the May 1941 coup.

Prelude and Mobilisation

In April 1941, Prime Minister Winston Churchill and commanders including Archibald Wavell assessed Iraqi developments alongside crises in Greece and Crete, prompting rapid redeployment of forces from Palestine and Transjordan and naval assets from Aden and the Mediterranean Fleet. The Royal Air Force reinforced squadrons at Habbaniya and Shaibah while the Iraqi Army under officers like Salah al‑Din al‑Bakr consolidated in Mosul and Baghdad, assisted by German and Italian aircrews linked to Fliegerführer Irak missions and diplomatic envoys such as Fritz Grobba. British logistics coordinated convoys through the Persian Gulf and staged infantry from the British Indian Army and King's African Rifles to prepare for offensive operations.

Invasion and Major Operations

British forces launched operations on 2 May 1941 with landings and advances from Basra and air operations from Habbaniya; columns from Khuzestan and Kuwait advanced toward Baghdad while units under Major General William Slim and Brigadier Robert Cassels moved along established rail and road axes. The campaign combined rapid mechanised thrusts, airborne reconnaissance, and coordinated artillery support drawn from units like the Royal Horse Artillery and Indian Armoured Corps as British formations sought to relieve besieged garrisons and to capture key transport hubs such as Fallujah and Ramadi, confronting Iraqi divisions loyal to Rashid Ali al‑Gilani.

Naval and Air Campaigns

The Royal Navy secured the Persian Gulf and supported amphibious operations near Basra and Khor al‑Amaya while protecting convoys en route from Aden and the Suez Canal; naval gunfire and carrier‑based aircraft from ships of the Eastern Fleet provided close support. The Royal Air Force operated from Habbaniya and bases in Palestine and Aden, contesting the skies against German and Italian aircraft including Heinkel He 111 and Caproni types flown by crews dispatched by Luftwaffe liaison parties, and conducted strategic reconnaissance to interdict Iraqi supply lines and to assist advancing columns.

Key Battles and Sieges

The defence and relief of RAF Habbaniya was a focal action in which forces under Air Vice‑Marshal Harry George Smart and ground‑defence units repelled Iraqi besiegers, followed by British advances that captured Fallujah and forced Iraqi withdrawals toward Baghdad; clashes at Khanaqin and the Hamrin Hills tested British logistical reach. The short siege of Basra and the fighting for Habbaniya and Ramadi involved combined arms engagements with notable roles by units such as the 4th Cavalry Brigade (India) and elements of the Iraqi Infantry Division, while aerial interdiction shaped the outcome of sieges and the collapse of pro‑Axis resistance in northern approaches near Mosul.

Aftermath and Political Consequences

By the end of May 1941 British forces had reoccupied Baghdad and restored a pro‑British administration led by figures allied to Nuri al‑Said and the regency for Faisal II, prompting resignations and exile for coup leaders like Rashid Ali al‑Gilani and contributing to the flight of German personnel from Iraq. The campaign influenced subsequent Anglo‑Soviet negotiations over Iran and precipitated the Anglo‑Soviet invasion of Iran in August 1941 to secure Trans‑Iranian Railway routes for Lend‑Lease to the Soviet Union and to safeguard oil supplies at Abadan and Kirkuk. Politically, the intervention affected British prestige in the Arab world, altered the careers of Iraqi politicians such as Nuri al‑Said and military officers in the Iraqi Army, and set precedents for postwar influence.

Legacy and Historical Assessment

Historians debate the campaign’s long‑term impact on Iraqi nationalism and Anglo‑Arab relations, contrasting interpretations offered by scholars of Middle Eastern history who emphasize anti‑colonial sentiment and analyses in strategic studies that stress imperial lines of communication to India and the Soviet Union. Military assessments highlight the effectiveness of combined operations by the Royal Air Force, Royal Navy, and British Indian Army in expeditionary warfare, while political studies trace continuities to later events including the 1958 Iraqi coup d'état and evolving British policy toward Palestine and Egypt. The 1941 campaign remains a case study in rapid intervention, air‑power influence, and the interaction of regional nationalism with global conflict.
