The amphibious Battle of Gela was the opening engagement of the United States portion of the Allied Invasion of Sicily. United States Navy ships landed United States Army troops along the eastern end of the south coast of Sicily; and withstood attacks by Luftwaffe and Regia Aeronautica aircraft while defending the beachhead against German and Italian tanks until the Army captured the Ponte Olivo Airfield for use by United States Army Air Forces planes.
