Factual error: HMS Rodney which along with KGV sank the Bismarck is wrongly portrayed. Her 16 inch guns were all forward of the main superstructure.
Suggested correction: The Rodney was a Nelson class battleship all her guns were forewarning of the superstructure.
Factual error: The Director of Operations is handed a fuel state for KGV and Rodney, and is advised they are 140 miles astern of Bismarck. He asks if they steam at full speed can they catch her. Since Bismarck can steam at 30 knots, and the British ships at 28 and 23 knots respectively, it was a question that shouldn't have even been broached.
Suggested correction: Because of damage to her fuel tanks from Prince of Wales Bismarck had to reduce speed to 20 knots.
