U-boat
Torpedoed Allied convoys
A U-boat is a German submarine, especially from World War I or World War II.
The term comes from German *Unterseeboot* (undersea boat).
U-boats conducted devastating campaigns against Allied shipping, particularly in the Atlantic: The convoy was attacked by a U-boat wolf pack.
The word appears almost exclusively in historical contexts.
