Welcome to this page that modestly covers "everything" regarding the Second World War, with obviously an important part for operation Overlord. This has not only the objective of establishing a western front with the depression of the Atlantic Wall, but the ultimate goal is the destruction of the Nazi regime !
I needed a “Headquarter” in order to discuss this vast subject ! The name SHAEF seems perfectly match it ...
The 6 December 1943, Army General Dwight D. Eisenhower was appointed “Supreme Commander Allied Expeditionary Force” (Supreme Commander of the Allied Expeditionary Forces) and his staff became SHAEF (Supreme Headquarters Allied Expeditionary Force or “Supreme Staff of the Allied Expeditionary Forces”), installed Camp Griffiss at Bushy Park; the absorba the Cossac. This staff reworked the Operation Overlord plan created by Frederick E. Morgan and Ray Barker until its final version, who was executed on 6 June 1944. Walter B. Smith became leader of the Eisenhower staff and Morgan the Deputy Chief of Staff. The Land Forces Command for the initial part of the invasion was provided by the General Bernard Montgomery.
SHAEF remained in the United Kingdom until sufficient forces were deployed to justify his transfer to France. At this moment, Montgomery ceased to command all land forces, but continued as Commander in Chief 21th British Army Group (21 AG) on the east wing of the beachhead in Normandy, and the 12e United States Army Group (12 AG) controlled by the Lieutenant General Omar Bradley was created in the western wing of the bridgehead. As a breakthrough in Normandy took place, the Allies launched the’invasion of southern France, the 15 August 1944 with the 6e United States Army Group (6 AG) under the command of Lieutenant-General Jacob L. Devers. When the invasion of southern France, the 6 AG was under the command of Headquarters Allied Forces (Allied Forces Headquarters) Mediterranean Theater of Operations, but after a month passed under the command of SHAEF including advanced PC was successively moved in Bayeux, Saint Lo and Jullouville. In September 1944, the main SHAEF took place at the’Trianon Palace at Versailles and an outpost totaled Reims where was signed the the surrender 7 May 1945. The 26 avril 1945, another outpost SHAEF moved to Frankfurt. After the surrender of Germany, advanced and main PC SHAEF definitively established in Frankfurt to organize the disarmament of the German army. Comprising over 16 000 officers and enlisted men at this time, SHAEF was dissolved on 14 July 1945.
