Confederate Submarine C.S.S. Hunley | History of SC Slide Collection

In an effort to disrupt the federal blockade, the Confederacy resorted to many ingenious plans, but perhaps the most daring of all was the attempt to build and use a submarine. The "Hunley" eventually succeeded in destroying one Union blockader, but it sank in the process. This is a sketch of how the submarine would work: eight men powered it by turning a crank attached to a propeller.
