Supreme Headquarters Allied Expeditionary Force

Eisenhower transferred from command of the Mediterranean Theater of Operations to command SHAEF, which was formed in Camp Griffiss, Bushy Park, Teddington, London, from December 1943; an adjacent street named Shaef Way, and a gate into the park called Shaef Gate, remain to this day.^[1] Southwick House was used as an alternative headquarters near Portsmouth. Its staff took the outline plan for Operation Overlord created by Lieutenant General Sir Frederick E. Morgan, Chief of Staff to the Supreme Allied Commander (Designate) (COSSAC), and Major General Ray Barker.^[2] Morgan, who had been appointed chief of staff to the Supreme Allied Commander (designate) in mid-March 1943 began planning for the invasion of Europe before Eisenhower's appointment^[3] and moulded the plan into the final version, which was executed on 6 June 1944. That process was shaped by Eisenhower and the land forces commander, General Sir Bernard Law Montgomery, for the initial part of the invasion.

SHAEF remained in the United Kingdom until sufficient forces were ashore to justify its transfer to France.^[4] At that point, Montgomery ceased to command all land forces but continued as Commander in Chief of the British 21st Army Group (21 AG) on the eastern wing of the Normandy bridgehead. The US 12th Army Group (12 AG) commanded by Lieutenant General Omar Bradley was created as the western wing of the bridgehead. As the breakout from Normandy took place, the Allies launched the invasion of southern France on 15 August 1944 with the US 6th Army Group (6 AG) under the command of Lieutenant General Jacob L. Devers. During the invasion of southern France, the 6 AG was under the command of the Allied Forces Headquarters (AFHQ) of the Mediterranean Theatre of Operations, but after one month command passed to SHAEF. By this time, the three Army Groups had taken up the positions on the Western Front in which they would remain until the end of the war—the British 21 AG to the North, the American 12 AG in the middle and the 6 AG to the South. By December 1944, SHAEF had established itself in the Trianon Palace Hotel in Versailles, France.^[5] In February 1945, it moved to Reims and on 26 May 1945, to Frankfurt.^[6]

SHAEF commanded the largest number of formations ever committed to one operation on the Western Front, with American, Free French, British and Canadian forces. It commanded all Allied airborne forces as an airborne army, as well as three army groups that controlled a total of eight field armies;

• First Allied Airborne Army
  • all Allied airborne divisions, brigades and paratrooper transport wings
• British 21st Army Group
  • First Canadian Army
  • Second British Army
• US 12th Army Group
  • First United States Army
  • Third United States Army
  • Ninth United States Army
  • Fifteenth United States Army
• US 6th Army Group
  • French First Army
  • Seventh United States Army

SHAEF also controlled substantial naval forces during Operation Neptune, the assault phase of Overlord, and two tactical air forces: the US Ninth Air Force and the RAF Second Tactical Air Force. Allied strategic bomber forces in the UK also came under its command during Operation Neptune.

After the surrender of Germany, SHAEF was dissolved on 14 July 1945.

With respect to the U.S. forces, it was replaced by U.S. Forces, European Theater (USFET).^[6] USFET was reorganized as EUCOM (European Command, not to be confused with the present-day United States European Command) on 15 March 1947.^[6][12]

The 1948–1951 Western Union Defence Organization's (WUDO) command structure was largely patterned on SHAEF's structure.^[13]

Starting in April 1951 when the North Atlantic Treaty Organization (NATO) cannibalised WUDO, it was put under the command of Supreme Allied Commander Europe Dwight D. Eisenhower in Supreme Headquarters Allied Powers Europe (SHAPE; Allied Command Europe [ACE]), comprising many of the same allies that were part of SHAEF. WUDO, followed by SHAPE, were in many respects the successors to SHAEF.

SHAPE is currently the headquarters of NATO's Allied Command Operations (ACO). Since 1967 it has been located at Casteau, north of the Belgian city of Mons,^[14] but it had previously been located, from 1953, at Rocquencourt, next to Versailles, France.

From 1951 to 2003, SHAPE was the headquarters of Allied Command Europe (ACE). Since 2003 it has been the headquarters of ACO, controlling all NATO operations worldwide.

The European Union has established a Military Planning and Conduct Capability (MPCC), which is due to gain more tasks and may rival SHAPE's dominance as the primary forum for multinational European missions. ^{[citation needed]}
