By July 1942, the British and Indian forces in Burma had completed their fighting retreat into India, and Alexander, having yet again been mentioned in despatches for his Burma service, was recalled to the United Kingdom. He was at first selected to command the British First Army, which was to take part in Operation Torch, the Anglo-American invasion of French North Africa. However, following a visit in early August to Egypt by the British Prime Minister, Winston Churchill, and the Chief of the Imperial General Staff (CIGS), General Sir Alan Brooke, Alexander flew to Cairo on 8 August to replace General Claude Auchinleck as C-in-C of Middle East Command, the post responsible for the overall conduct of the campaign in the desert of North Africa. At the same time, Lieutenant-General Montgomery replaced Auchinleck as GOC of the British Eighth Army. Alexander presided over Montgomery's victory at the Second Battle of El Alamein and the advance of the Eighth Army to Tripoli, for which Alexander was elevated to a Knight Grand Cross of the Order of the Bath, and, after the Anglo-American forces of the First Army (under Lieutenant-General Kenneth Anderson) from Operation Torch and the Eighth Army converged in Tunisia in February 1943, they were brought under the unified command of a newly formed 18th Army Group headquarters, commanded by Alexander and reporting to General Dwight D. Eisenhower, the Supreme Allied Commander in the Mediterranean Theater of Operations (MTO) at Allied Forces Headquarters (AFHQ). The American General Omar Bradley, who fought in the Tunisian Campaign, then commanding the U.S. II Corps, credited Alexander's patience and experience with helping an inexperienced United States "field command mature and eventually come of age."
