More than one hundred and fifty years ago, when the U.S. was using Naval ships that looked more like the USS Constitution than the mammoth super carriers of today and the Civil War was still raging, a glimpse of the future crept along beneath the surface of Charleston Harbor.
Above the surface, the USS Housatonic set about on its usual patrol. Its responsibility was to enforce the Union blockade along the coast of South Carolina, helping to strangle the Confederacy of the supplies it required to prolong the war effort.
From his vantage point on the deck, John Crosby, the ship’s acting master, spotted something in the distance off the starboard bow. The dark silhouette first appeared to be a “porpoise, coming to the surface to blow,” but Crosby had been warned of the possibility of an attack from what he knew as the Confederate’s “infernal machine.” He quickly sounded the alert, bringing the ship’s crew to the deck and unleashing an onslaught of small arms fire on the mysterious body approaching from beneath the surface.
Beneath the havoc and the gunfire, eight men huddled together in a new invention, the submarine, and continued their approach. Four weeks earlier, the USS New Ironsides had been attacked and damaged by a semi-submersible confederate vessel, but their ship, the H.L. Hunley, was a full-fledged submarine. It was dangerous merely to operate, as thirteen men, including the ship’s inventor, had already died in training exercises, but the small ship’s captain, Confederate Lieutenant George Dixon, was undeterred. Unbeknownst to him, he and his crew were destined to join that figure of sailors lost to the depths that night, but not before changing the course of naval history.
