 The Allied invasion of Italy occurred during September 1943, for a number of key reasons not least important of which was that support for the war in Italy had been declining and it was thought that an invasion would hasten the efforts of the new government that had deposed Benito Mussolini, which was seeking peace.Furthermore, the weakening of Axis control of the Mediterranean supply routes eased the pressure on Allied forces operating in the Middle and Far East, as well as on the efforts to supply to Soviet Union.Operation Husky — the invasion of Sicily in July 1943 — was successful, serving as a springboard for the invasion of the mainland.
