Nearly certainly unrelated: Some billeted troops wanted to catapult Stümpfelbach into Alpine redoubt territory during the last days of the war. The worse the odds the higher the honor. Resident population understandably somewhat lukewarm about the whole concept. A check point committee headed by Madame Nuss was therefore dispatched to route away any liberating troops until saner minds could prevail. Takes some time to remove all those unsightly tank barriers and to roll out the welcoming mat. Unclear if Patton himself was detoured or if it was just a lonely ambulance driver which had lost his way. The back country roads of the Schurwald can be tricky. Switchback terrain. Cinematographic ending: A face saving warning shot at the nearest clock face.
