On 7 August 1941, General Doyen was the Head of the French Mission, Armistice Commission at Wiesbaden, Germany.
It was around the time that the Allies invaded French North Africa and Germany responded by occupying the whole of France.
On 6 June 1944, the Allies invaded Normandy, France; shortly after French Troops under Jean Lattre De Tassigny invaded the coast of Provence in south of France.
Paris was liberated on by 25 August and General DeGaulle was reforming the French Military for the invasion of Germany.
De Gaulle was very keen on France playing a major role in the war; as a result General Doyen was recalled to service on 1 Feb 1945.
