On a dark night in February of 1864, the H.L. Hunley, the first submarine to sink an enemy ship in combat, torpedoed the Union blockade ship USS Housatonic, a feat that would not be repeated for another 50 years. But fate was not kind to the Hunley that night as it sank with all of its crew on board before it could return to shore. Considered by many to be the Civil War's greatest mystery, the Hunley's demise and its resting place have been a topic of discussion for historians and Civil War buffs alike for more than a hundred years.

Adding still more to the intrigue, the vessel was discovered in 1995 by a dive team led by famed novelist and shipwreck hunter Clive Cussler, sparking an underwater investigation that resulted in the raising of the Hunley on August 8, 2000. Since that time, the extensive research and restorative efforts underway have unraveled the incredible secrets that were locked within the submarine at the bottom of the Atlantic Ocean.
