New clues to sinking of Confederate sub
The Hunley was the first submarine to sink another ship, but even if it wasn't, it would still be an important piece of submarine history, if only because it sank three times. This man-powered, spar torpedo armed, submarine sank twice before it was finally used to sink the USS Housatonic. Then it sank for the third time, this time without being recovered. An important and interesting piece of naval submarine history.
