Angus Konstam: Confederate Submarines and Torpedo Vessels 1861-65 [2004] paperback

The primary Union strategy during the American Civil War was a massive naval blockade of the entire Southern coastline of the Confederacy, and it was in the effort to counter this blockade that the Confederates developed their first submarines and torpedo boats. This book traces the development of these new technologies, including the CSS 'Little David' and 'Hunley' - respectively the first torpedo boat and submarine to sink an enemy warship. The wreck of the 'Hunley' was raised in 2000, and this is the first book ever to integrate details of its recovery with an account of Confederate submarines in action.
