During "Crusader" on 27 November 1941, Galloway was promoted acting major general, to become Deputy Chief of the General Staff (DCGS) at GHQ Middle East. He replaced Neil Ritchie, who had assumed command of Eighth Army. In recognition of his efforts in North Africa, Galloway was awarded the Distinguished Service Order and Mentioned in Despatches in December. In his new role Galloway spent some time in the United States selecting equipment for the Eighth Army before returning to London in May 1942 to take up the important role of Director of Staff Duties at the War Office. His rank was upgraded from an acting one to a temporary one in December 1942 and, in July 1943, he was appointed to command 1st Armoured Division which was re-fitting in North Africa having fought through the North Africa Campaign since the Battle of Gazala.
