About Joachim Peiper
We all knew the role of Colonel Hessler was based on the real-life SS-Standartenführer Joachim Peiper, who wasn't killed in the battle of the bulge, but survived the WAR without a scratch. He has served 11 years in jail after the war and lived somewhere in France before die (killed) in a accident.
Why would he had lived in another country where obviously more anti-Nazi people could have messed up with him? Was he expelled from his vaterland? Why the French authority allows his residency?
