Originally the I Armored Corps under command of Lieutenant General George S. Patton, it made landfall at Morocco during Operation Torch as the Western Task Force, the first all-U.S. force to enter the European war. Following successful defeat of the Wehrmacht under Field Marshal Erwin Rommel in North Africa, the I Armored Corps was redesignated the Seventh Army on 10 July 1943 while at sea en route to the Allied invasion of Sicily as the spearhead of Operation Husky.
