"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 tanks and Italian tanks of the Livorno Division until the Army captured the Ponte Olivo Airfield for use by United States Army Air Forces planes
The battle convinced United States Army officers of the value of naval artillery support, and revealed problems coordinating air support from autonomous air forces during amphibious operations."
