On 16 January 1944, Eisenhower returned to take control of the Allied forces for Overlord. His headquarters was designated Supreme Headquarters, Allied Expeditionary Force (SHAEF). With SHAEF taking over the operational functions, ETOUSA was combined with SOS to create what would become the Communications Zone (Com Z) once operations commenced. A complicating factor was the creation of the First United States Army Group under Lieutenant General Omar N. Bradley, who sought to place logistical functions under his command. Lee also conflicted with Eisenhower's chief of staff, Lieutenant General Walter B. Smith. While Eisenhower respected Lee's administrative talents, Smith resented Lee's position as deputy theater commander, which allowed Lee to bypass Eisenhower, and occasionally frustrate Smith's efforts to rein in the operational commanders like Bradley and Patton through logistics. Smith arranged for his own protégé, Major General Royal Lord, to be appointed as Lee's deputy. On 21 February 1944, Lee was promoted to lieutenant general, along with Courtney H. Hodges, Richard K. Sutherland and Raymond A. Wheeler. Lee began a curious habit of wearing his stars on both the back and front of his helmet, which added to his reputation as an eccentric. Lee was often called "Jesus Christ Himself" based on his initials. He was also known as "Court House" and "Church House" Lee.
