Why the British Empire Invaded Its Own Ally in the Middle of World War II
In short: In June 1941, British forces launched Operation Exporter to invade Syria and Lebanon. Though technically allies, these territories were controlled by Vichy France, a vassal of Nazi Germany. Fearing Axis powers would use the region to strike Egypt, the British launched a fierce, often forgotten campaign against their former partners.
The catalyst for the invasion was the Anglo-Iraqi War in May 1941. Following a coup in Iraq, Vichy French authorities allowed German aircraft to refuel at Syrian airfields, effectively turning the region into an Axis staging ground. Admiral François Darlan, a staunch Anglophobe, facilitated this support, even proposing an offensive against British-held Iraqi oilfields. British leadership, particularly General Archibald Percival Wavell, was initially reluctant to intervene, fearing the distraction would jeopardize the Western Desert Campaign. However, pressure from Winston Churchill and the strategic necessity of securing the northern flank against a potential German advance through the Caucasus forced their hand.
The campaign began on 8 June 1941, with British, Australian, Indian, and Free French forces attacking from Palestine and Iraq. Contrary to expectations that the French would offer little resistance, the Armée du Levant fought with unexpected vigor, viewing the defense of Syria as a matter of national honor. The fighting was intense, spanning battles from the Litani River to Damascus. British forces, many of whom were novices, struggled in the harsh, mountainous terrain, while the Vichy Air Force initially inflicted significant damage on British naval and ground units before being systematically dismantled.
By 10 July, with Australian forces nearing Beirut, the French sought an armistice. The ceasefire took effect on 12 July, followed by the signing of the Convention of Acre on 14 July. The campaign resulted in over 4,600 British and Commonwealth casualties and thousands of French losses. While the operation successfully secured the region and prevented a northern front against Egypt, it remains a relatively obscure chapter of the war. The aftermath saw the eventual independence of Syria and Lebanon, though the transition was marked by further tension, including the 1945 Levant Crisis, which saw British forces intervene once more to curb French attempts to suppress nationalist demonstrations.
