The Cruel Sea (1953 film)

"This is a story of the Battle of the Atlantic, the story of an ocean, two ships and a handful of men. The men are the heroes. The heroines are the ships. The only villain is the sea—the cruel sea—that man has made more cruel."

"For us, the Battle of the Atlantic was becoming a private war. If you were in it, you knew all about it. You knew how to keep watch on filthy nights, and how to go without sleep; and how to bury the dead and how to die without wasting anyone's time."
