No 211 Group or No. 211 (Medium Bomber) Group was a Group of the Royal Air Force (RAF) formed on 10 December 1941 by renaming Nucleus Group Western Desert. The group was officially disbanded from 3 February 1942 to 12 March 1943, although some references refer to some of its original squadrons during this period as being with 211 Group. On 12 March 1943, the group reformed as No. 211 (Offensive Fighter) Group and Air Commodore Richard Atcherley assumed command of the group on 11 April 1943. At this time, 211 Group was the principle fighter force of the Desert Air Force (DAF) commanded by Air Vice Marshal Harry Broadhurst, and DAF was a sub-command of Air Marshal Sir Arthur Coningham's Northwest African Tactical Air Force (NATAF).
The group included many units from the South African Air Force (SAAF), as well as several from the Royal Australian Air Force (RAAF) and the United States Army Air Forces (USAAF), with one each from the Hellenic Air Force and Royal Canadian Air Force. Many personnel from other British Commonwealth air forces also served in RAF, SAAF, RAAF and RCAF units, under the British Commonwealth Air Training Plan and related arrangements.
Throughout the North African Campaign, the medium bomber and fighter squadrons of Air Headquarters Western Desert, also known at various times of the campaign as Air Headquarters Libya, Western Desert Air Force, or DAF, were primarily assigned to either 211 Group or No. 212 (Fighter Control) Group (later No. 212 (Fighter) Group).
