Allied Force Headquarters (AFHQ) was the headquarters that controlled all Allied operational forces in the Mediterranean Theatre of World War II from late 1942 until the end of the war in Europe in May 1945.
AFHQ was established in the United Kingdom in August 1942 under Lieutenant General Dwight David Eisenhower in order to command the forces committed to Operation Torch, the Allied invasion of French North Africa, set for November. Eisenhower had the title Commander-in-Chief, Allied Expeditionary Force. Shortly after the establishment of the headquarters, "Expeditionary" was deleted from its title, for reasons of operational security. Eisenhower thus became Commander-in-Chief, Allied Force.
Towards the end of 1942, there was a need to unify command of the Allied forces in North Africa, since those from the west, the British First Army, under the command of Lieutenant-General Kenneth Arthur Noel Anderson, landed during Operation Torch, and those from the east, the British Eighth Army, commanded by Lieutenant-General Bernard Law Montgomery, that had fought and won the Second Battle of El Alamein, were now close enough together to need coordination. Therefore, in February 1943, AFHQ assumed control of the Eighth Army advancing from the east as well.
Eisenhower remained in command of AFHQ until January 1944, overseeing the Allied invasion of Sicily (with the codename of Operation Husky), which began on 10 July 1943 and the Allied invasion of the Italian mainland (codenamed Operation Baytown and Operation Avalanche), on 3 September 1943. Eisenhower then a full general, returned to the United Kingdom in December to assume command of the Allied forces assembling for Operation Overlord, the Allied invasion of Normandy, scheduled for the spring of 1944. He was succeeded by General Sir Henry Maitland Wilson. Wilson's title became Supreme Commander, Mediterranean Theater of Operations.
