First Submarine Sinks a Warship: The Hunley Makes History, Then Vanishes

The H. L. Hunley sank twice during trials, killing thirteen crew members including its inventor. On February 17, 1864, it sank a third time — but not before torpedoing the USS Housatonic off Charleston. The Union warship went down in five minutes. The Hunley never surfaced. When divers found it in 1995, the crew was still at their stations. Nobody knows what killed them. The sub was intact.
