H. L. Hunley, also known as theHunley,CSSH. L. Hunley, orCSSHunley, was asubmarine of theConfederate States of America that played a small part in theAmerican Civil War.Hunley demonstrated the advantages and dangers of undersea warfare. She was the first combat submarine to sink a warship (USS Housatonic), althoughHunley was not completely submerged and, following her attack, was lost along with her crew before she could return to base. Twenty-one crewmen died in the three sinkings ofHunley during her short career. She was named for her inventor,Horace Lawson Hunley, shortly after she was taken into government service under the control of theConfederate States Army atCharleston, South Carolina.
Hunley, nearly 40 ft (12 m) long, was built atMobile, Alabama, and launched in July 1863. She was then shipped by rail on 12 August 1863 to Charleston.Hunley (then referred to as the "fish boat", the "fish torpedo boat", or the "porpoise") sank on 29 August 1863 during a test run, killing five members of her crew. She sank again on 15 October 1863, killing all eight of her second crew,including Horace Lawson Hunley himself, who was aboard at the time, even though he was not a member of the Confederate military. Both timesHunley was raised and returned to service.
On 17 February 1864,Hunley attacked and sank the 1,240-tonUnited States Navy[2]screwsloop-of-warHousatonic, which had been onUnion blockade-duty in Charleston's outer harbor.Hunley did not survive the attack and sank, taking all eight members of her third crew with her, and was lost.
Finally located in 1995,Hunley was raised in 2000 and is on display inNorth Charleston, South Carolina, at theWarren Lasch Conservation Center on theCooper River. Examination in 2012 of recoveredHunley artifacts suggested that the submarine was as close as 20 ft (6.1 m) to her target,Housatonic, when her deployed torpedo exploded, which caused the submarine's sinking.[3]
TheCivil War, April 12, 1861 – April 9, 1865, was a domestic American war where theUnion (also called the North) was locked in combat with theConfederates (also called the South).
In the beginning of the war, combat was fought with bayonets, horses, wooden ships, and imprecise artillery. During the course of the battle the weaponry changed and such things as: mines, accurate guns, more deadly bullets, torpedoes, and "ironclad" ships became a new standard. Though most of the fighting occurred on land, a critical element of the war was the power struggle at sea. Whichever side controlled the coastline also controlled the shipping imports from Europe and Coastal America, which contained critical resources such as clothes, food, artillery, medicine, and, at times, reinforcements. The Hunley was created to destroy theUnion blockade and help gain this all-important coastline advantage.[4][5][6]
Horace Lawson Hunley provided financing forJames McClintock to design three submarines:Pioneer inNew Orleans, Louisiana,American Diver built in Mobile, andHunley.[7]
While the United States Navy was constructing its first submarineUSS Alligator, in late 1861, the Confederacy was developing their own. Likely having within them an incessant loyalty to the Confederate states as well as understanding the financial gains that would come from sinking enemy ships,[8] Hunley, McClintock, and Baxter Watson first builtPioneer. She was tested in February 1862 in theMississippi River and was later towed toLake Pontchartrain for additional trials. TheUnion advance towards New Orleans caused the men to abandon development, however, andPioneer was scuttled the following month.[7]McClintock noted the significance that a boat capable of moving in any direction at any depth could be made, but ultimately decided that such a vessel could be improved.[8] Hunley, Watson, and McClintock moved to Mobile to develop a second submarine,American Diver. They collaborated with Park & Lyons machine shops owners, Thomas Park and Thomas Lyons, in the construction of the vessel.[8][7][9] Their efforts were supported by theConfederate States Army.LieutenantWilliam Alexander of the21st Alabama Infantry Regiment was assigned to oversee the project. The builders experimented with several methods of providing the new submarine with self-propulsion, including McClintock's electromagnetic drive, followed by a customsteam engine, but eventually settled on a simple hand-cranked propulsion system as they felt that the time and money lost in implementing such an engine would not be worth the trouble.[8]American Diver was ready for harbor trials by January 1863, but she proved too slow to be practical. Nonetheless, it was decided to tow the submarine down the bay toFort Morgan and attempt an attack on the Union blockade. However, the submarine foundered in the rough waters caused by foul weather and the currents at the mouth ofMobile Bay and sank.[10] The crew escaped, but the boat was not recovered.[11]

Construction ofHunley began soon after the loss ofAmerican Diver. At this stage,Hunley was variously referred to as the "fish boat", the "fish torpedo boat", or the "porpoise". Legend held thatHunley was made from a cast-offsteam boiler—perhaps because a cutaway drawing by William Alexander, who had seen her, showed a short and stubby machine. In fact,Hunley was designed and built for her role, and the sleek, modern-looking craft shown in R.G. Skerrett's 1902 drawing is an accurate representation. Each end was equipped withballast tanks that could be flooded by valves or pumped dry byhand pumps. Extra ballast was added using iron weights bolted to the underside of the hull. If 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.
The hull of the ship is estimated to originally have been 4 feet 3 inches (1.30) in diameter. The two hatches, accessible by means ofconning tower, located in the forward andaft of the vessel, are estimated to have originally measured at 16.5 inches (420 mm) in width and 21 inches (530 mm) in length. The small sizing of the hatches and the cramped quarters made entering, exiting, and maneuvering about the ship remarkably difficult. Hunley was designed for a crew of eight, seven to turn the hand-cranked ducted propeller at about 3.5horsepower (2.6 kW), and one to steer and direct the boat. At the height of its speed, Hunley could reach 4knots [Wills, 2017].
By July 1863,Hunley was ready for a demonstration. Supervised by ConfederateAdmiralFranklin Buchanan,Hunley successfully attacked a coal flatboat in Mobile Bay. Following this, the submarine was shipped by rail to Charleston, South Carolina, on 12 August 1863. However, the Confederate military seized the submarine from her private builders and owners shortly after arriving, turning her over to the Confederate Army.Hunley would operate as a Confederate Army vessel from then on, although Horace Hunley and his partners would remain involved in her further testing and operation. While sometimes called CSSHunley, she was never officially commissioned into service.
Confederate Navy LieutenantJohn A. Payne ofCSSChicora volunteered to beHunley's captain, and seven men fromChicora andCSSPalmetto State volunteered to operate her. On 29 August 1863,Hunley's new crew was preparing to make a test dive when Lieutenant Payne accidentally stepped on the lever controlling the sub's diving planes as she was running on the surface. This causedHunley to dive with one of her hatches still open. Payne and two others escaped, but the other five crewmen drowned.
H. L. Hunley crew lost 29 August 1863:
The Confederate Army took control ofHunley, with all orders coming directly from GeneralP. G. T. Beauregard, with Lt.George E. Dixon placed in charge. On 15 October 1863,Hunley failed to surface after a mock attack, killing all eight crewmen. Among these was Hunley himself, who had joined the crew for the exercise and possibly had taken over command from Dixon for the attack maneuver. The Confederate Navy once more salvaged the submarine and returned her to service.
H. L. Hunley Crew lost 15 October 1863:[12]
Hunley was initially intended to attack by using a floatingexplosive charge with acontact fuse (atorpedo in 19th-century terminology). The Hunley's methodology of deploying the explosive charge consisted of them diving beneath the ship and catching the charge on the side/hull of the vessel and re-emerging outside of the blast range of the explosive. This plan was discredited and not used as the possibility ofHunley becoming entangled in the rope, the rope drifting away from the ship, or the charge exploding on the submarine was too great.
Instead, aspar torpedo—a copper cylinder containing 135 pounds (61 kilograms) ofblack powder—was attached to a 22-foot (6.7 m)-long wooden spar, as seen in illustrations made at this time. Mounted onHunley's bow, the spar was to be used when the submarine was 6 ft (1.8 m) or more below the surface. Previous spar torpedoes had been designed with a barbed point: the spar torpedo would be jammed in the target's side by ramming and then detonated by a mechanical trigger attached to the submarine by a line so that as she backed away from her target, the torpedo would set off. However, archaeologists working onHunley discovered evidence, including a spool of copper wire and components of a battery, that it may have been electrically detonated. In the configuration used in the attack onHousatonic, it appearsHunley's torpedo had no barbs and was designed to explode on contact as it was pushed against an enemy vessel at close range.[13] After Horace Hunley's death, General Beauregard ordered that the submarine should no longer be used to attack underwater. An iron pipe was then attached to her bow, angled downwards so the explosive charge would be delivered sufficiently underwater to make it effective. This was the same method developed for the earlier "David" surface attack craft used successfully against theUSSNew Ironsides.The Confederate Veteran of 1902 printed a reminiscence authored by an engineer stationed at Battery Marshall who, with another engineer, made adjustments to the iron pipe mechanism beforeHunley left on her last fatal mission on 17 February 1864. A drawing of the iron pipe spar, confirming her "David" type configuration, was published in early histories of submarine warfare.
Hunley made her only attack against an enemy target on the night of 17 February 1864. The target was United States Navy ship,USSHousatonic, a 1,240-long-ton (1,260 t)[2] wooden-hulled steam-powered screw sloop-of-war with 12 largecannons, which was stationed at the entrance to Charleston, about 5 miles (8.0 kilometres) offshore.Hunley happened to be on patrol around that area at the time.[8] Helmed by Lieutenant George E. Dixon with a crew of seven and desperate to break thenaval blockade of the city, H. L. Hunley successfully attackedHousatonic, rammingHunley's only spar torpedo against the enemy'shull.[14] The torpedo was detonated, sendingHousatonic to the bottom in three minutes,[8] along with five of her crewmen.[15]Hunley and her crew went missing after the attack. They would not be found for over 100 years.
After the attack,H.L. Hunley failed to return to her base. At one point, there appeared to be evidence thatHunley survived as long as one hour following the attack, which occurred at about 20:45. The day after the attack, the commander of "Battery Marshall" reported that he had received "the signals" from the submarine indicating she was returning to her base.[16] The report did not say what the signals were. A postwar correspondent wrote that "two blue lights" were the prearranged signals,[17] and a lookout onHousatonic reported he saw a "blue light" on the water after his ship sank.[18] "Blue light" in 1864 referred to apyrotechnic signal[19] in long use by the U.S. Navy.[20] It has been falsely represented in published works as a blue lantern; the lantern eventually found on the recoveredH. L. Hunley had a clear, not a blue, lens.[21] Pyrotechnic "blue light" could be seen easily over the four-mile (6 km) distance between Battery Marshall and the site ofHunley's attack onHousatonic.[22]
After signaling, Dixon's plan could have been to take his submarine underwater to make a return to Sullivan's Island, although he left no confirmed documentation of this plan. At one point, the finders ofHunley suggested she was unintentionally rammed by USSCanandaigua when thatwarship was going to rescue the crew ofHousatonic, but no such damage was found when she was raised from the bottom of the harbor. Instead, all evidence and analysis eventually pointed to the instantaneous death ofHunley's entire crew at the moment of the spar torpedo's contact with the hull ofHousatonic. Upon removal of the silt inside the hull, the skeletons of the crewmembers were found seated at their stations with no signs of skeletal trauma.[23] In October 2008, scientists reported they had found that the crew ofHunley had not set her pump to remove water from the crew's compartment, and this might indicate she was not flooded until after they died. In January 2013, it was announced that conservator Paul Mardikian had found evidence of a copper sleeve at the end ofHunley's spar. This finding indicated the torpedo had been attached directly to thespar, meaning the submarine may have been less than 16 feet (5 m) fromHousatonic when the torpedo exploded.[3][24] In 2018, researchers reported that thekeel blocks, which the crew could release from inside the vessel to allow the sub to surface quickly in an emergency, had never been released.[25]
The short distance between the torpedo and the vessel, in addition to the signs that the crew died instantaneously and without a struggle to survive, led a team of blast trauma specialists from Duke University to theorize that theHunley's crew was killed by theblast itself,[14] which could have transmitted pressure waves inside the vessel without damaging its hull. Their research, which included scaled experiments with live black powder bombs, provided data indicating the crew was likely killed by the explosion of their own torpedo, which could have caused immediate pulmonary blast trauma. The Duke team's experiments and results were published August 2017 in the peer-reviewed journalPLoS One[14] and eventually became the subject of the bookIn the Waves: My Quest to Solve the Mystery of a Civil War Submarine.[23] Although their conclusions have been disputed by archaeologists with theNaval History and Heritage Command (NHHC), the NHCC website[26] disputing the results of the scientific experiments contains several inconsistencies. For example, the website implies that the experiments are not valid because "a 1/8th inch plate at 1/6th scale is only 0.02 inches thick," but neither of these dimensions is relevant to either the originalHunley or the scale model used by Duke.[26][14][27]
Years afterHunley went missing, when the area around the wreck ofHousatonic was surveyed, the sunkenHunley was found on the seaward side of the sloop, where no one had considered looking before. This later indicated that the ocean current was going out following the attack onHousatonic, takingHunley with her to where she was eventually found and later recovered.[citation needed]
Hunley's discovery was described by William Dudley, Director of Naval History at theNaval Historical Center as "probably the most important find of the century."[28]

The discovery ofHunley has been claimed by two different individuals. Underwater archaeologistE. Lee Spence, president,Sea Research Society, reportedly discoveredHunley in 1970,[29][30] and has a collection of evidence[31] claiming to validate this, including a 1980 Civil Admiralty Case.[32] The court took the position that the wreck was outside the jurisdiction of theU.S. Marshals Office, and no determination of ownership was made.[33]
On 13 September 1976, the National Park Service submitted the Sea Research Society's (Spence's) location forH. L. Hunley for inclusion on theNational Register of Historic Places. Spence's location forHunley became a matter of public record whenH.L. Hunley's placement on that list was officially approved on 29 December 1978.[34] Spence's bookTreasures of the Confederate Coast, which had a chapter on his discovery ofHunley and included a map complete with an "X" showing the wreck's location, was published in January 1995.[35]
Diver Ralph Wilbanks located the wreck in April 1995 while leading aNUMA dive team originally organized by archaeologist Mark Newell and funded by novelistClive Cussler,[36] who announced the find as a new discovery[37] and first claimed that the location was in about 18 ft (5.5 m) of water over one mile (1.6 km) inshore ofHousatonic, but later admitted to a reporter that that was false.[38] The wreck was actually 100 yd (91 m) away from and on theseaward side ofHousatonic in 27 feet (8.2 m) of water. The submarine was buried under several feet of silt, which had concealed and protected the vessel for over a hundred years. The divers exposed the forward hatch and the ventilator box (the air box for the attachment of her twin snorkels) to identify her. The submarine was resting on her starboard side, at about a 45-degree angle, and was covered in a1⁄4 to3⁄4 inch (0.64 to 1.91 cm) thick encrustation ofrust bonded with sand and seashell particles. Archaeologists exposed part of the ship's port side and uncovered the bow dive plane. More probing revealed an approximate length of 37 feet (11 m), with the entire vessel preserved under the sediment.[39]
On 14 September 1995, at the official request of Senator Glenn F. McConnell, Chairman, South CarolinaHunley Commission,[40] E. Lee Spence, with South Carolina Attorney General Charles M. Condon signing, donatedHunley to the State of South Carolina.[41][42][43] Shortly thereafter, NUMA disclosed to government officials Wilbank's location for the wreck which, when finally made public in October 2000, matched Spence's 1970s plot of the wreck's location well within standard mapping tolerances.[44] Spence avows that he discoveredHunley in 1970, revisiting and mapping the site in 1971 and again in 1979, and that after he published the location in his 1995 book he expected NUMA to independently verify the wreck asHunley, not to claim that NUMA had discovered her. NUMA was actually part of aSCIAA expedition directed by Dr.Mark M. Newell and not Cussler.[45][46] Dr. Newell swore under oath that he used Spence's maps to direct the joint SCIAA/NUMA expedition and credited Spence with the original discovery. Dr. Newell credits his expedition only with the official verification ofHunley.[47]
Thein situ underwater archaeological investigation and excavation culminated with the raising ofHunley on 8 August 2000.[48] A large team of professionals from the Naval Historical Center'sUnderwater Archaeology Branch,National Park Service, theSouth Carolina Institute of Archaeology and Anthropology, and various other individuals investigated the vessel, measuring and documenting her before removal. Once the on-site investigation was complete, harnesses were slipped underneath the sub and attached to a truss designed byOceaneering International. After the last harness had been secured, the crane from the recovery bargeKarlissa B hoisted the submarine from the sea floor.[49][50] She was raised from the open waters of the Atlantic Ocean, just over 3.5 nautical miles (6.5 km) from Sullivan's Island outside the entrance to Charleston Harbor. Despite having used a sextant and hand-held compass thirty years earlier to plot the wreck's location, Dr. Spence's 52 m (171 ft) accuracy turned out to be well within the length of the recovery barge, which was 64 m (210 ft) long.[51][52] On 8 August 2000, at 08:37, the sub broke the surface for the first time in more than 136 years, greeted by a cheering crowd on shore and in surrounding watercraft, including author Clive Cussler. Once safely on her transporting barge,Hunley was shipped back to Charleston. The removal operation concluded when the submarine was secured inside theWarren Lasch Conservation Center, at the formerCharleston Navy Yard in North Charleston, in a specially designed tank of fresh water to await conservation until she could eventually be exposed to air.
The exploits ofHunley and her final recovery were the subject of an episode of the television seriesThe Sea Hunters, calledHunley: First Kill. This program was based on a section ("Part 6") in Clive Cussler's 1996 non-fiction book of the same name (which was accepted by the Board of Governors of the Maritime College of the State University of New York in lieu of his Ph.D. thesis).[53]
In 2001, Clive Cussler filed a lawsuit against E. Lee Spence for unfair competition, injurious falsehood, civil conspiracy, and defamation.[54] Spence filed a countersuit against Cussler, in 2002, seeking damages, claiming that Cussler was engaging in unfair competition, tortious interference, and civil conspiracy by claiming Cussler had discovered the location of the wreck ofHunley in 1995 when she had already been discovered by Spence in 1970, and that such claims by Cussler were damaging to Spence's career, and had caused him damages over $100,000.[55] Spence's lawsuit was dismissed through summary judgment in 2007, on the legal theory that, under the Lanham Act, regardless of whether Cussler's claims were factual or not, Cussler had been making them for over three years before Spence brought his suit against Cussler; thus the suit was not filed within the statute of limitations.[56] Cussler dropped his suit a year later,[57] after the judge agreed that Spence could introduce evidence in support of his discovery claims as a truth defense against Cussler's claims against him.[58]
Hunley may be viewed during tours at the Warren Lasch Conservation Center in Charleston. A replica is on display at theUSS Alabama Battleship Memorial Park, Mobile, Alabama, alongside theUSS Alabama (BB-60) and theUSS Drum (SS-228).
The crew was composed of
Apart from the submarine commander, Lieutenant George E. Dixon, the identities of the volunteer crewmen ofHunley had long remained a mystery.Douglas Owsley, aphysical anthropologist working for theSmithsonian Institution'sNational Museum of Natural History, examined the remains and determined that four of the men were American born, while the four others were of European birth, based on the chemical signatures left on the men's teeth and bones by the predominant components of their diet. Four men had eaten plenty of corn, an American diet, while the remainder ate mostly wheat and rye, a mainly European diet. By examining Civil War records and conductingDNA testing with possible relatives, forensic genealogist Linda Abrams identified the remains of Dixon and the three other Americans: Frank G. Collins of Fredericksburg, Va., Joseph Ridgaway, and James A. Wicks.[21] Identifying the European crewmen has been more problematic, but was apparently solved in late 2004. The position of the remains indicated that the men died at their stations and were not trying to escape from the sinking submarine.[61]
On 17 April 2004, the remains of the crew were laid to rest atMagnolia Cemetery, in Charleston.[62] Tens of thousands of people attended including some 6,000 reenactors and 4,000 civilians wearing period clothing. Color guards from all five branches of the U.S. armed forces—wearing modern uniforms—were also in the procession.[63] Even though only two of the crew were from the Confederate States, all were buried with full Confederate honors, including being buried with the 2nd Confederate national flag,[64] known as theStainless Banner.
Another surprise occurred in 2002, when lead researcher Maria Jacobsen,[65][66] examining the area close to Lieutenant Dixon, found a misshapen $20 gold piece, minted in 1860, with the inscription"Shiloh April 6, 1862, My life Preserver G. E. D." on a sanded-smooth area of the coin's reverse side, and aforensic anthropologist found a healed injury to Lt. Dixon'ship bone. The findings matched a family legend that Dixon's sweetheart, Queenie Bennett, had given him the coin to protect him. However, the supposed relationship between Bennett and Dixon has not been supported by archaeological investigations of the legend. Dixon had the coin with him at theBattle of Shiloh, where he was wounded in the thigh on 6 April 1862. The bullet struck the coin in his pocket, saving his leg and possibly his life. He had the gold coin engraved and carried it as a lucky charm.[67][68]
Adam Jon Kronegh of the Danish National Archive identified the J.F. Carlsen ofHunley. Johan Frederik Carlsen was born inÆrøskøbing 9 April 1841. The last year he was registered in the census of Ærøskøbing was 1860, when he was registered as a "sailor". His father was registered as a cobbler, and the teeth of Carlsen's remains inHunley still bear significant marks of a so-called "tailor's notch", probably from helping his father with needle and thread from childhood.[69] In 1861, J.F. Carlsen entered the freight shipGrethe ofDragør. The ship landed in Charleston in February 1861, where records in the Danish military archives show that Carlsen deserted the ship. In June 1861, he enteredJefferson Davis (the Confederate privateer brig originally namedPutnam) as a mate.[70][71]
TheHunley is on display at the Warren Lasch Conservation Center. The center includes artifacts recovered from insideHunley and exhibits about the submarine.
