On July 10, 1943, the Allies launched Operation Husky before sunrise, a massive amphibious assault on the southern shores of the island. For the next three days it involved more than 3,000 ships landing over 150,000 ground troops, covered by more than 4,000 aircraft. They were opposed on the island by only two German divisions, as Nazi leadership continued to believe the main assault would come at Sardinia and Corsica.
