The Allied invasion of Sicily, also known as the Battle of Sicily and Operation Husky, was a major campaign of World War II in which Allied forces invaded the Italian island of Sicily in July 1943 and took it from the Axis forces. The island was defended by the Italian 6th Army and the German XIV Panzer Corps. The invasion paved the way for the Allied invasion of mainland Italy and initiated the Italian campaign that removed Italy from the war.
With the conclusion of the North Africa campaign in May 1943, the victorious Allies had for the first time ejected the Axis powers from a theatre of war. Now at Italy's doorstep, the Allied powers—led by the United States and United Kingdom—decided to attack Axis forces in Europe via Italy, rather than Western Europe, due to the wavering Italian morale, control over Mediterranean sea lanes, and the vulnerability of German supply lines along the Italian Peninsula.
To divert some Axis forces to other areas, the Allies engaged in deception operations, the most successful of which was Operation Mincemeat. Operation Husky began on the night of 9/10 July 1943 with a large amphibious and airborne operation, followed by a six-week land campaign that ended on 17 August.
The Allies achieved their primary aims, Axis air, land and naval forces were driven from the island and the Mediterranean was opened to Allied merchant ships for the first time since 1941. These events led to the ousting of Italian leader Benito Mussolini and the fall of his regime, which was replaced by the First Badoglio government. Italy's collapse necessitated German troops replacing Italian forces in the country, and to a lesser extent the Balkans, resulting in one-fifth of the German army being diverted from the Eastern Front, a proportion that would remain until near the end of the war.[15]
Background
[edit]Allies
[edit]The plan for Operation Husky called for the amphibious assault of Sicily by two Allied armies, one landing on the south-eastern and one on the central southern coast. The amphibious assaults were to be supported by naval gunfire, as well as tactical bombing, interdiction and close air support by the combined air forces. As such, the operation required a complex command structure, incorporating land, naval and air forces. The overall commander was American General Dwight D. Eisenhower, as Commander-in-Chief (C-in-C) of all the Allied forces in North Africa. British General Sir Harold Alexander acted as his second-in-command and as the 15th Army Group commander. The American Major General Walter Bedell Smith was appointed as Eisenhower's Chief of Staff.[16] The overall Naval Force Commander was the British Admiral Sir Andrew Cunningham.
The Allied land forces were from the American, British and Canadian armies, and were structured as two task forces. The Eastern Task Force (also known as Task Force 545) was led by General Sir Bernard Montgomery and consisted of the British Eighth Army (which included the 1st Canadian Infantry Division). The Western Task Force (Task Force 343) was commanded by Lieutenant General George S. Patton and consisted of the American Seventh Army. The two task force commanders reported to Alexander as commander of the 15th Army Group.[17]
The U.S. Seventh Army consisted initially of three infantry divisions, organized under II Corps, commanded by Lieutenant General Omar Bradley. The 1st and 3rd Infantry Divisions, commanded by Major Generals Terry Allen and Lucian Truscott respectively, sailed from ports in Tunisia, while the 45th Infantry Division, under Major General Troy H. Middleton, sailed from the United States via Oran in Algeria. The 2nd Armored Division, under Major General Hugh Joseph Gaffey, also sailing from Oran, was to be a floating reserve and be fed into combat as required. On 15 July, Patton reorganized his command into two corps by creating a new Provisional Corps headquarters, commanded by his deputy army commander, Major General Geoffrey Keyes.[18]
The British Eighth Army had four infantry divisions and an independent infantry brigade organized under XIII Corps, commanded by Lieutenant-General Sir Miles Dempsey, and XXX Corps, commanded by Lieutenant-General Sir Oliver Leese. The two divisions of XIII Corps, the 5th and 50th (Northumbrian) Infantry Divisions, commanded by Major-Generals Horatio Berney-Ficklin and Sidney Kirkman, sailed from Suez in Egypt. The formations of XXX Corps sailed from more diverse ports: the 1st Canadian Infantry Division, under Major-General Guy Simonds, sailed from the
