On July 10, 1943, the Allied forces launch Operation Husky, invading Sicily by air and sea. The attack is successful, largely in part due to Operation Mincemeat, in which British intelligence covertly planted false papers about Allied movements in Italy in an effort to divert the Germans away from the island.
The Germans took the bait moving resources and troops to other areas, opening up Sicily for the Allies to attack and earn their first victory in what would be the start of the Italian Campaign of World War II.
