young woman whom Himmler believed was his niece. The Doctor uses the sacrificial knife to cut Ace's bonds, and uses Ace's last nitro-nine-a capsule to give escape to the top of the castle's tower. Outside, Goering has arrived with a panzer division, advancing against Drachensberg. The Doctor explains that he had told Goering that treachery against Hitler was taking place at the castle. The War Chief's zombified soldiers are unable to repel Goering. As the battle concludes, Hitler arrives by aeroplane. The Doctor explains to Hitler that Kriegslieter was behind everything, while also convincing him that both Himmler and Goering are loyal heroes of the Reich.

This has the desired effect, luring the Timewyrm out into the open. The Doctor offers to allow the Timewyrm to take over his mind if she releases Hitler. The Timewyrm accepts, but the Doctor's lantern was really an extension of the TARDIS forcefield which he uses to repel the Timewyrm. Hitler becomes confused, suddenly robbed of his power and confidence. The Doctor persuades him to halt the advance on Dunkirk and delay the invasion of
