Heeresgruppe Mitte
In June 1944, during Operation Bagration, the Third Panzer and the rest of Army Group Centre were shattered by the Red Army and driven back into Poland and East Prussia. On 16 August 1944, Reinhardt was given command of Army Group Centre. In December, renewed Soviet attacks drove Army Group Centre out of Poland into northern Prussia. Reinhardt was retired from active duty in January 1945.
