Continuity mistake: In the scene where a gun battle with the enemy has ended, Sgt. Joe Gunn calls out the names of the soldiers. All answer except the South African soldier (Stegman). Gunn makes his way to the trench where Stegman is. Gunn sees Stegman has been shot dead. He takes Stegman's hat and there is a bullet hole in the hat but no blood on the hat or on his shirt. For a head shot there would be a considerable amount of blood. (01:09:50)

Revealing mistake: In the scene where we first get a glimpse of the German fighter, it banks to the left and it can be seen there are no fuselage-mounted machine guns. Then when we have a close up of the pilot, the machine guns are mounted just in front of the cockpit. When the aircraft is making its strafing run, the fuselage-mounted machine guns are not there.

Revealing mistake: In the scene where a British soldier (Williams) and Sgt. Joe Gunn (Humphrey Bogart) are in a trench, the British soldier is shot dead by a German sniper. Joe Gunn moves in for a closer look and it can be seen that the "dead" soldier is breathing, his shoulder is moving. (01:15:30)
