A paratrooper hero with the Knight's Cross of the Iron Cross with Oak Leaves (though the medal shown in the series is the Knight's Cross of the Iron Cross with Oak Leaves and Swords), Major Mohn was severely wounded at Stalingrad by a Russian bayonet and served on Hitler's personal staff before coming to Colditz. He is a Nazi Party member in good standing, and very highly connected (although the series does not mention to whom). He constantly finds himself in conflict with the Kommandant, for he holds the philosophy that the war is still going on at Colditz and is frustrated by what he perceives as the treating of prisoners with "kid gloves". The prisoners loathe him and do whatever they can to foil him or antagonise him at every turn. Unfortunately for them, he is ruthlessly intelligent and occasionally pulls off a devastating capture. Major Mohn is a paratroop officer and his relationship with the SS appears to be fairly chilly. He is visibly upset with the SD orders given at the end of the episode "The Guests" and seems nervous around the Obergruppenführer and Hauptsturmführer in "Very Important Person." It appears that the reason why Major Mohn would prefer to take SS orders unquestioningly than risk SS reprisals is that he appreciates, apparently better than the Kommandant, what the SS is capable of. In contrast to the honourable Kommandant and Ulmann, Mohn is a sinister and villainous character. However his belief in the cause is shaken when he learns that his brother died ignominiously, crushed by a Russian tank.Lieutenant Anton Lehr (Grahame Mallard) - Lieutenant Lehr is the first Security Officer of Colditz, but in the fourth episode is posted to the front.
