Upper Rhine
With the defeat of Operation North Wind and the impending collapse of the Colmar Pocket, the Upper Rhine High Command was inactivated on January 24, 1945, and the responsibility for the defense of the upper Rhine region was again returned to Army Group G. The staff of the Upper Rhine High Command was used to staff the newly formed Eleventh SS Panzer Army on the Eastern Front. Heinrich Himmler was sent to command Army Group Vistula ("Heeresgruppe Weichsel"), also on the Eastern Front.
