Confederate Sailors on HL Hunley Killed by Their Own Weapon

Duke University Biomedical Engineering Ph.D. Rachel Lance evaluated several prevailing theories for why the Confederate combat submarine HL Hunley and its 8-man crew vanished after sinking the Union battleship Housatonic in Charleston Bay on Feb. 17, 1864. After extensive scale-model testing with air cannons and black powder explosions, Lance says the men were subjected to “blast lung“ by their own torpedo and died instantaneously.
