Notes:

Allied Armies in Italy, commanded by Field Marshal Sir Harold Alexander, was the title of the highest Allied field headquarters in Italy, during the middle part of that campaign. It was activated in 1943 in Algiers, North Africa, to plan the invasion of Sicily, Operation Husky. Its main forces for this job were the British Eighth Army and the U.S. Seventh Army. For some time, it was under command of British Field Marshal Harold Alexander.15th Army Group was renamed Allied Central Mediterranean Force on 17 January 1944. ACMF was commanded by Field Marshal Sir Harold Alexander, and was in turn renamed Allied Armies in Italy on 1 March of the same year. The final change of title of the headquarters, back to 15th Army Group, came when Alexander handed over command to General Mark W. Clark on 11 December 1944. Both earlier and later in the campaign, the headquarters was known as 15th Army Group; it reported to the Joint Allied command AFHQ the theatre command for the Mediterranean Theatre.
