From December 1941 to August 1943, he was Commander-in-Chief of the German Fifteenth Army in France.[9] In Italy from August 1943 he commanded German Tenth Army,[10] which was responsible for the delaying actions through the successive defensive lines built across Italy. Notable in this context were the defences on the Winter Line from November 1943 to May 1944 and the fighting in the autumn of 1944 on the Gothic Line.
In October 1944, he was temporarily raised to overall command in Italy (Army Group C) when Field Marshal Albert Kesselring was seriously injured in a car crash.[11] In January 1945, on Kesselring's return, he left Italy to command Army Group Courland in East Prussia. When Kesselring was moved in March 1945 to command German Army Command West (OB West) in France, Vietinghoff returned as the supreme German commander in Italy.[12]
At the end of April 1945, he made contact with the Allied forces and on 29 April, his representative General Karl Wolff signed on his behalf at the Royal Palace in Caserta the instrument of surrender on 2 May 1945 at noon. Afterwards he spent two and a half years in British captivity at Bridgend Island Farm (Special Camp XI) among high-ranking German prisoners.
After the war Vietinghoff was a member of the expert group dealing with the question of German rearmament. In October 1950 he wrote the Himmerod memorandum, named after the Himmerod Abbey where it was written, on behalf of the Adenauer government, on West German contributions to European defence. He died on 23 February 1952 in Pfronten.
^In German personal names, von is a preposition which approximately means 'of' or 'from' and usually denotes some sort of nobility. While von (always lower case) is part of the family name or territorial designation, not a first or middle name, if the noble is referred to by their last name, use Schiller, Clausewitz or Goethe, not von Schiller, etc.
