Sinking of USS Housatonic, Naval battle site in Charleston Harbor, United States
The location marks the spot where the Confederate submarine H.L. Hunley sank the USS Housatonic using a spar torpedo on February 17, 1864.
The encounter changed naval warfare as it represented the first successful submarine attack on an enemy vessel, resulting in the loss of five Union sailors.
The discovery of both vessels' remains in Charleston Harbor has provided researchers with valuable information about Civil War naval technology and construction methods.
The wreck site lies approximately four miles from the entrance of Charleston Harbor at coordinates 32.7186°N 79.8047°W in waters reaching 30 feet deep.
The submarine H.L. Hunley disappeared after signaling its success, and its wreckage remained hidden until its discovery in 1995 by underwater archaeologists.
