Factual error: The survivors of the Wormhoudt massacre were not picked up by the same SS soldiers who had carried out the massacre as in the series. They were picked up by a Wehrmacht ambulance unit, which is how they managed to survive to become prisoners of war.
Factual error: Captain James Lynn-Allen wasn't shot by an SS officer whilst remonstrating with him about the treatment of his men. He was shot whilst trying to escape and his sacrifice allowed another soldier to successfully escape.
