H.L. Hunley was a Confederate submersible that demonstrated the advantage and danger of undersea warfare. Although not this nation's first submarine, Hunley was the first submarine to engage and sink a warship.

Privately built in 1863 by Park and Lyons of Mobile, Alabama, Hunley was fashioned from a cylindrical iron steam boiler, which was deepened and also lengthened through the addition of tapered ends. Hunley was designed to be hand powered by a crew of nine: eight to turn the hand-cranked propeller and one to steer and direct the boat. As a true submarine, each end was equipped with ballast tanks that could be flooded by valves or pumped dry by hand pumps. Extra ballast was added through the use of iron weights bolted to the underside of the hull. In the event the submarine needed additional buoyancy to rise in an emergency, the iron weight could be removed by unscrewing the heads of the bolts from inside the vessel.

On 17 February 1864, the Confederate submarine made a daring late night attack on USS Housatonic, a 1,240-ton (B) sloop-of-war with 16 guns, in Charleston Harbor off the coast of South Carolina. H.L. Hunley rammed Housatonic with spar torpedo packed with explosive powder and attached to a long pole on its bow. The spar torpedo embedded in the sloop's wooden side was detonated by a rope as Hunley backed away. The resulting explosion that sent Housatonic with five crew members to the bottom of Charleston Harbor also sank Hunley with its crew of eight. H.L. Hunley earned a place in the history of undersea warfare as the first submarine to sink a ship in wartime.

This is an overview of the main map area showing the pier entrance, pier, cargo crane, and H L Hunley:

This is another overview of the main map area from the pier side:

This is a detail shot showing the spar torpedo of the H L Hunley. The spar torpedo was essentially a large explosive on a pole or spar. The method for using such a weapon was to use the pointed end of the spar to pierce the underside of a ship thus attaching the explosive then back away while at the same time pulling a fuse and lighting the explosive thereby sinking or crippling the ship. This Forged spar torpedo works by triggering the fuse via a trip mine at the end of the ignition cord (small antenna) this creates a lighted fuse effect leading up to the main explosives which ignite with fury so step back.

This is a detail shot highlighting the forward entry hatch, snorkels, and dive planes (the angled plates at the front of each entry hatch were known as cutwaters and were intended to make the vessel more hydrodynamic while cruising at sea level as well as below).

This is a detail shot highlighting the aft entry hatch, propeller shaft, control surfaces and cables, and rudder.

This is a bird's-eye-view of the main map area which includes the pier entrance, pier, cargo crane, and H L Hunley.

This is the entrance to the pier complete with dual guard bunkers each housing 4 grenades and a sword a piece.

This is the pier leading to the cargo crane and gang-plank/walkway to the H L Hunley. The crane houses 2 teleporters and a sniper rifle. The 2 teleporters each lead to the 2 entry hatches to the Hunley which both have 3 DMRs a piece.

This is a reverse-side detail of the cargo crane.

This is the cargo crane's controls:

This is one of the camps leading to the pier entrance.

These are the other 2 camp areas on the small mountain leading to the pier entrance.
