Continuity mistake: At the end of the first attack by the destroyer - where she misses the U-boat and throws her bombs further away - the boatswain makes 22, then 23 strokes on the slate of the Control Centre,thus counting the number of depth charges used against the boat. A few seconds later, in a shot from another angle, with the slate in full view, we see only 22 strokes. (01:03:30)
2nd Lieutenant: First time on U-boat?
Lt. Werner: Yeah. First time. It's gonna be exciting.
2nd Lieutenant: Do you have a will?
Lt. Werner: Excuse Me?
2nd Lieutenant: 13 boats down last moth. Sank with men and mice. Exciting, huh?
