When SS General Hans Kammler, a key figure in the Nazis’ secret weapons programme, vanished in 1945 he was said to have taken his own life. Yet recently discovered documents cast doubt on this claim. Although he oversaw a vast network of underground sites essential to the Nazi war effort, and was instrumental in the construction of concentration camps whose inmates were put to work as forced labourers, his disappearance meant he avoided prosecution for war crimes at Nuremberg.

Absorbing documentary HITLER’S SECRET WEAPONS MANAGER (November 2nd, 9.45pm) investigates the various rumours concerning Kammler’s fate, including the possibility that the Allies considered his knowledge valuable enough to have him covertly spirited away across the Atlantic, behind a convenient smokescreen of mystery and confusion.
