Kriegsverbrechergefängnis Spandau
Following Korea, Speirs attended a Russian language course in 1956 and was assigned as a liaison officer to the Red Army in Potsdam, East Germany. In 1958, he became the American governor of the Spandau Prison in Berlin, where prominent Nazis such as Rudolf Hess were imprisoned. Prisoner Albert Speer mentions in his book, "Spandau: The Secret Diaries," a "hard-nosed, irritating American Commandant"; that man was later identified as Speirs.
