Like an injured dolphin in a sling, the H. L. Hunley is lifted from her grave off Charleston, South Carolina, the skeletons of her eight-man crew still sealed inside. On a winter night in 1864 the Confederate vessel was lost with all hands shortly after she attacked and sank the U.S.S. Housatonica feat that ushered in the dawn of undersea warfare. Now a team of archaeologists and forensic scientists is attempting to solve a mystery as old as the Civil War: Why did the Hunley sink, and how did her crew perish?
