Scientists say a pole on the front of the Confederate submarine H.L. Hunley designed to plant explosives on enemy ships may hold a key clue to its sinking during the Civil War.
The experts are to release their findings Monday at a North Charleston lab where the hand-cranked sub is being preserved and studied. The Hunley was the first submarine in history to sink an enemy warship.
The pole, called a spar, was once placed at the front of the sub and used to plant a powder charge into the Union blockade ship Housatonic in 1864.The Housatonic sank, while the Hunley and its eight-man crew never returned.
