The first submarine to be used as an instrument of war was an egg-shaped craft that carried only one person. Four submersible vessels were built during the American Civil War by the fleet. In 1864, a confederate submarine, the Hunley, blew up the USS Housatonic in Charleston, South Carolina, harbor, but the explosion too destroyed itself.
