They said that they had not shot at him because they thought he had gone off his head.
Yeah that's right, the Germans wouldn't shoot anyone who they thought might be mad. The Third Reich was well known for it's deep compassion towards the mentally ill.
And I can't see what Geoff Bacon has to do with this story. What Bill Millin did was without doubt, an immensely courageous act. A courageous act which must have had massive morale boosting consequences at a pinnacle and rather grim moment during WW2. Geoff Bacon was a chauffeur during WW2 who was tragically murdered under appalling circumstances. I can't see any connection between the two stories.
