I remember watching a ww2 episode about dude (he was tasked with helping breaking Mussolini out in Italy, kidnapping some guy's son who wanted to break ranks with the nazis and when that didn't work killed him. Hilter then replaced with with a die hard nazi sympathizer to keep then on the axis side until the end of the war. His forces were responsible for a lot of the confusion behind the lines during the battle of the Bulge).
