The H.L. Hunley, a Confederate submarine during the American Civil War, made history as the first combat sub to sink an enemy warship, the USS Housatonic.
But on that same mission in 1864, the Hunley disappeared with its eight-man crew.
When the vessel was finally recovered over a century later, researchers were stunned: the crew, including George E. Dixon, were still seated calmly at their stations, with no signs of panic or escape attempts.
The mystery remained unsolved until a 2017 study by researchers from Duke University. Their findings revealed that the submarine’s own torpedo likely caused the crew’s deaths.
Unlike modern weapons, the Hunley’s explosive was mounted on a long pole extending from the sub.
When detonated, the blast sent a powerful shock wave back through the submarine’s hull. Scientists concluded the impact was strong enough to kill the crew instantly, before they could react or attempt to escape.
This explains why the men were found in place: they likely never realized what happened. In making naval history, they were also caught in the deadly force of their own weapon.
