Why The Hunley Sank?
Scientists say they may have found an important clue in the mystery of why the Confederate submarine
Hunley sank 140 years ago after making history by sinking an enemy warship in battle. Archaeologists and others working to restore the submarine recovered six years ago from the bottom of the Atlantic Ocean off the coast of Sullivans Island have found evidence the forward hatch may have been opened intentionally on the night the sub sank.
