Another notable officer under his command was his chief of staff, Colonel Norman Cota, who would later become a major general and be remembered for his leadership on Omaha Beach during the invasion of Normandy on June 6, 1944, D-Day. The division participated in the invasion of French North Africa. The division landed in Oran, Algeria on November 8, 1942, as part of Center Task Force of Operation Torch under the command of Major General Lloyd Fredendall. Elements of the division then took part in combat in the Tunisia Campaign at Maktar, Medjez el Bab, Kasserine Pass, Gafsa, El Guettar, Béja, and Mateur, from January 21, 1943 to May 9, 1943, helping secure Tunisia. In July, 1943, the division participated in the Allied invasion of Sicily, codenamed Operation Husky. In a 3 March 1943 letter to the Army Chief of Staff, Marshall, General Dwight D. "Ike" Eisenhower, the Supreme Allied Commander in North Africa, expressed his confidence in the 1st Infantry Division's two leaders: "Terry Allen seems to be doing a satisfactory job; so is Roosevelt." In spite of Allen's successes, Major General Omar Bradley, the II Corps commander, was highly critical of both Allen and Roosevelt's wartime leadership style. "While the Allies were parading decorously through Tunis," Bradley wrote, "Allen's brawling 1st Infantry Division was celebrating the Tunisian victory in a manner all its own. In towns from Tunisia all the way to Arzew, the division had left a trail of looted wine shops and outraged mayors. But it was in Oran...that the division really ran amuck. The trouble began when SOS (Services of Supply) troops, long stationed in Oran, closed their clubs and installations to our combat troops from the front. Irritated by this exclusion, the 1st Division swarmed into town to 'liberate' it a second time." Bradley continued: "Despite their [prodigious] talents as combat leaders, neither Terry Allen nor Brigadier General Theodore Roosevelt Jr, the assistant division commander, possessed the instincts of a good disciplinarian. They looked upon discipline as an unwelcome crutch to be used by less able and personable commanders." Despite this, Bradley admitted that "none excelled the unpredictable Terry Allen in the leadership of troops." Bradley's resentment of Allen stands in marked contrast to that of Patton, the U.S. Seventh Army commander in Sicily. Although Patton and Allen frequently argued and even insulted each other, particularly when discussing tactics and leadership styles, the former recognized Allen's competence in building a fighting division.
