Five men – two officers and three crewmen – went down with their ship while an unknown number of Union Navy sailors were injured. The survivors were later rescued by other elements of the Charleston blockading force. The first ship on the scene was .
H.L. Hunley won her first victory, but was lost at sea the same night while returning home to
Sullivan's Island. It was originally thought that
H.L. Hunley was sunk as the result of her own torpedo exploding, but some claim that she survived as long as an hour after destroying
Housatonic. Support for the argument of
H.L. Hunleys brief survival is a report by the commander of
Fort Moultrie on Sullivan's Island that prearranged signals from the sub were observed, and answered; he did not say what the signal was. Further support comes from the testimony of a lookout on the sunken
Housatonic, who reported seeing a "blue light" from his perch in the sunken ship's rigging. There was also a post-war claim that two "blue lights" were the prearranged signal between the sub and Fort Moultrie. "Blue light" at the time of the Civil War was a pyrotechnic signal in long use by the US Navy. Modern claims in published literature on
H.L. Hunley have repeatedly and mistakenly been that the "blue light" was a blue lantern, when in fact no blue lantern was found on the recovered
H.L. Hunley, and period dictionaries and military manuals confirm the 1864 use and meaning of "blue light." This was the last time
H.L. Hunley was heard from, until her recovery from the waters off Charleston, South Carolina. While returning to her naval station
H.L. Hunley sank for unknown reasons. However, a team of historians managed to examine the submarine's remains, and theorized that a crewman on
Housatonic was able to fire a rifle round into one of
H.L. Hunleys viewing ports. A film entitled
The Hunley was made about the story of H.L. Hunley and the sinking of the submarine
H.L. Hunley. New evidence announced by archaeologists in 2013 indicates that
H.L. Hunley was less than away from the point of detonation – much closer than previously realized – and thus the explosion probably damaged the submarine as well as its target, although it was impossible to tell at the time due to
concretion covering the hull. Later studies showed that the crew was probably instantly killed through
blast injury caused by the close proximity of the torpedo, though this remains disputed. ==See also==
