The U.S. Seventh Army consisted initially of three infantry divisions, organized under II Corps, commanded by Lieutenant General Omar Bradley. The 1st and 3rd Infantry Divisions, commanded by Major Generals Terry Allen and Lucian Truscott respectively, sailed from ports in Tunisia, while the 45th Infantry Division, under Major General Troy H. Middleton, sailed from the United States via Oran in Algeria. The 2nd Armored Division, under Major General Hugh Joseph Gaffey, also sailing from Oran, was to be a floating reserve and be fed into combat as required. On 15 July, Patton reorganized his command into two corps by creating a new "Provisional Corps" headquarters, commanded by his deputy army commander, Major General Geoffrey Keyes.
