A 1960 World War II drama, based on the novel, The Last Nine Days of the Bismarck, by C. S. Forester. During the Battle Of The Atlantic, Britain must fight alone as Nazi Germany sends out its most powerful battleship to hunt the supply convoys that the country needs to survive. In command of the operation is Captain Jonathan Shepard (Kenneth More), a by-the-book commander and disciplinarian who prosecutes the fight heedless of the feelings of his subordinates. Has nothing to do with the Real Life Gargle Blaster from BrewDog Brewery.
