Trevor Howard makes for an eminently plausible "Lt. Cdr. Fraser" in command of a dilapidated ex-USN destroyer - renamed HMS Ballantrae - whose stiff upper lip, by the book, approach to his men causes considerable resentment. Gradually, though - and not before the ship has a few mishaps - he begins to turn them around before their ultimate mission to attack a Nazi-occupied French dry dock. A good ensemble cast including James Donald, Bernard Lee and Richard Attenborough help keep the pace quick and interesting. The latter part of the film is based on a real-life raid on St. Nazaire and is quite an exciting ride. I enjoyed this.
