Character mistake: On the way approaching town the camera pans to a woman's hanged body with a sign written in German around her neck. One of the crew asked Wardaddy what it said, to which he answered something like "It reads 'I am a coward who refused to fight for the German people'." That sign actually translates to "I wanted my children not to go fight" or Anglicized for better effect, "I refused to let my children to go to war." Interestingly, once into town, there appears the corpse of a hanged man with a sign written in German that does translate to what Wardaddy said of the first sign. (00:43:00)
