As a member of the SS, he was appointed to carry the blood-stained Blutfahne from the Munich Putsch. He was decorated with the Golden Party Badge, the Blood Order (no. 714), and the Coburg Badge, three of the most prized decorations of the NSDAP.[2] The "Blutfahne's" fate, which Grimminger was the guardian of, after the fall of the Third Reich in mid-1945 is unknown.[3]
