Richard Gibson did not take part in the final series, so the character of Herr Otto Flick was taken over by David Janson.
Herr Flick has undergone plastic surgery in order to facilitate his escape to South America when the Allies invade.
General Von Klinkerhoffen orders Colonel Von Strohm and Lieutenant Gruber to stay and fight to the end, so they decide to escape and hide – ending up at the cafe, walking into the attic bedroom just as René is making his final radio call to London.
The Gestapo officers' attempts to escape prove fruitless, but Helga regains possession of her missing piece of the painting.
Von Klinkerhoffen changes his mind and decides to formally surrender to the British at the cafe to spare the lives of the men under his command.
