„Prussian field marshals do not mutiny“, was the fatal credo leading militaries like Erich Manstein referred to when they were in conflict between soldier-like obedience and resistance against a criminal warlord. Rommel, Keitel, Manstein, Paulus, Udet und Canaris – not one of them had actively supported the resistance of July 20th, 1944. But only these men, holding key positions in Hitler’s war machinery, would have had the power to overthrow the terror regime from within. Guido Knopp and his team show the lives of the six leading Generals who – despite all their distance to the ideology of National Socialism – kept on being willing tools in Hitler’s merciless war.
