The H. L. Hunley is one of the most intriguing artifacts from the American Civil War, representing a bold leap in military technology and naval warfare. As the first submarine to sink an enemy warship in combat, it captured the imagination of both its contemporaries and future generations. The Hunley’s story is one of innovation, bravery, and tragedy, wrapped in a layer of mystery that has persisted for over 150 years. This article will explore the Hunley’s creation, its role in the Civil War, its eventual rediscovery, and the folklore surrounding it, offering a comprehensive view of this fascinating submarine.

The Birth of the H. L. Hunley

The American Civil War (1861-1865) was a conflict defined by technological innovation and strategic evolution. Both the Union and Confederate forces sought new ways to gain an advantage over their opponent. The Union’s naval blockade, part of General Winfield Scott’s Anaconda Plan, aimed to suffocate the Confederacy by cutting off its access to international trade and resources. This blockade severely threatened the Southern war effort, leading the Confederacy to explore unconventional methods to break it.

Submarines were not a new concept by the time of the Civil War; attempts at underwater vessels dated back to the 17th century. However, the challenges of building a functional and effective submarine were immense. The Confederacy, desperate for a means to counter the Union’s naval dominance, turned to the idea of submarines as a way to strike at the blockade’s heart.

The Visionaries Behind the Hunley

Horace Lawson Hunley, a wealthy lawyer and plantation owner with a keen interest in naval engineering, spearheaded the creation of the H. L. Hunley. Hunley partnered with James McClintock and Baxter Watson, two skilled engineers who had previously worked on other submarine projects. Together, they formed a team that combined technical expertise with the financial backing necessary to undertake such a risky and innovative project.

Hunley was not an engineer himself, but his vision and willingness to invest in the project were crucial to its realization. McClintock and Watson, on the other hand, brought practical experience to the table. Their collaboration was driven by a shared belief that a successful submarine could turn the tide of the war in favor of the Confederacy.

Early Prototypes

Before the Hunley, McClintock and Watson built two earlier prototypes: the Pioneer and the American Diver. The Pioneer was constructed in New Orleans in 1861 and was the first Confederate submarine to be tested. It had a cylindrical iron hull and was powered by a hand-cranked propeller. Despite some success in tests, the Pioneer was scuttled in Lake Pontchartrain to prevent its capture when Union forces threatened New Orleans.

The American Diver, built in Mobile, Alabama, was the second attempt. This vessel incorporated several design improvements based on lessons learned from the Pioneer. The American Diver was slightly larger and had a more refined propulsion system, but it, too, faced difficulties. It sank during a test run in Mobile Bay in early 1863 due to mechanical failure.

Final Design of the H. L. Hunley

The H. L. Hunley was the culmination of these earlier efforts and represented a significant advancement in submarine design. The submarine was approximately 40 feet long and 4 feet in diameter, with a cigar-shaped hull made of wrought iron. The choice of iron for the hull was crucial, as it provided the necessary strength to withstand underwater pressure while remaining buoyant.

One of the most innovative features of the Hunley was its propulsion system. Unlike modern submarines, which use engines or batteries, the Hunley was powered by a hand-cranked propeller. Eight crew members sat side by side along a central shaft, each turning the crank to propel the vessel forward. This manual propulsion system was both a strength and a limitation; while it allowed the submarine to move quietly and with some degree of control, it also required a physically fit crew and limited the submarine’s speed and endurance.

Another key feature of the Hunley was its spar torpedo, an explosive device mounted on a long iron pole, or spar, attached to the submarine’s bow. The torpedo was designed to be rammed into an enemy ship’s hull, with a contact fuse triggering the explosion. This method of attack was both daring and dangerous, as the submarine had to approach its target closely, making it vulnerable to counterattack.

The Hunley also featured ballast tanks that could be flooded or pumped out to control its buoyancy, allowing it to submerge and resurface as needed. The submarine’s hatches were fitted with glass portholes, providing the crew with a limited view of the outside world, although visibility was often poor.

Construction Process

The H. L. Hunley was constructed in Mobile, Alabama, under conditions that were far from ideal. The Confederate Navy lacked the resources and industrial capacity of the Union, and the construction of the submarine was difficult and labor-intensive. The iron hull was riveted together by hand, and the delicate mechanisms of the propulsion and ballast systems required precision engineering.

Despite these challenges, the Hunley was completed in mid-1863 and transported to Charleston, South Carolina, where it would be tested and deployed. The journey from Mobile to Charleston was itself an arduous task, as the submarine had to be shipped by rail and then by water, all while avoiding detection by Union forces.

Strategic Importance During the Civil War

Charleston, South Carolina, was one of the Confederacy’s most important ports and a key target of the Union blockade. The city’s defenders were determined to break the blockade, and the Hunley was seen as a potential game-changer. The submarine’s mission was to attack and sink a Union warship, demonstrating the Confederacy’s ability to strike back against the blockade.

The Hunley’s deployment was a high-stakes gamble. Submarine warfare was still in its infancy, and no one knew for sure if the Hunley would succeed or even survive its mission. However, the potential rewards were enormous; a successful attack could lift the blockade of Charleston and provide a much-needed boost to Confederate morale.

First Manned Submarine Attack

On the evening of February 17, 1864, the H. L. Hunley set out on its most famous mission. Its target was the USS Housatonic, a Union sloop-of-war stationed off the coast of Charleston. The Housatonic was a formidable ship, armed with powerful cannons and manned by an experienced crew. However, it was no match for the Hunley’s stealthy approach.

The Hunley’s crew, led by Lieutenant George E. Dixon, navigated the submarine silently through the waters toward the Housatonic. As they approached, the crew cranked the propeller to position the submarine for the attack. The spar torpedo was loaded and ready, and Dixon gave the order to strike.

At 8:45 PM, the Hunley rammed its spar torpedo into the side of the Housatonic. The explosion was immediate and devastating, tearing a hole in the Union ship’s hull and causing it to sink within minutes. Five Union sailors lost their lives in the attack, but most of the crew managed to escape in lifeboats.

The Hunley had achieved what no other submarine had done before: it had successfully sunk an enemy warship in combat. However, the victory was bittersweet. Shortly after the attack, the Hunley itself vanished, leaving behind no trace of its whereabouts. The submarine and its crew were presumed lost, and their fate would remain a mystery for more than a century.

Rediscovery of the H. L. Hunley

Search Efforts and Expeditions

The disappearance of the H. L. Hunley sparked one of the greatest maritime mysteries of the 19th century. Historians, archaeologists, and treasure hunters searched for the submarine for decades, but their efforts were fruitless. Theories about the Hunley’s fate ranged from it being sunk by the explosion of its own torpedo to it being swamped by a rogue wave.

Interest in the Hunley’s story persisted into the 20th century, with several expeditions launched to find the lost submarine. In the 1970s and 1980s, technological advances in underwater exploration made it possible to search the ocean floor more thoroughly. However, it wasn’t until 1995 that the Hunley was finally located by a team led by best-selling author and underwater explorer Clive Cussler.

Cussler’s team used sonar and magnetometers to scan the seabed off the coast of Charleston. After months of searching, they detected an anomaly that matched the size and shape of the Hunley. Divers were sent down to investigate, and they confirmed the discovery: the Hunley had been found buried in the silt approximately four miles from where the USS Housatonic had sunk.

Raising the Hunley

The discovery of the Hunley was a momentous event, but it was only the beginning of a long and delicate process. Raising the submarine from the ocean floor was a complex operation that required careful planning and execution. The Hunley was fragile after more than 130 years underwater, and any attempt to move it could cause irreparable damage.

In August 2000, the Hunley was carefully lifted from the seabed using a custom-made cradle and a system of cranes. The operation took several hours, with the team working slowly and methodically to avoid damaging the submarine. Once it was safely above water, the Hunley was transported to the Warren Lasch Conservation Center in Charleston, where it would undergo extensive preservation.

The raising of the Hunley was a historic event watched by millions around the world. It marked the first time in over a century that the submarine had seen the light of day, and it provided historians and scientists with an unprecedented opportunity to study one of the most significant artifacts of the Civil War.

What We Learned About the Submarine

The preservation of the Hunley revealed a wealth of information about its design, construction, and the conditions faced by its crew. One of the most significant discoveries was the position of the crew members’ remains, which were found seated at their stations, still gripping the crank handles that powered the propeller. This suggested that the crew may have died suddenly, possibly due to asphyxiation or the concussive effects of the torpedo explosion.

The submarine’s interior was remarkably well-preserved, with many of the original components still intact. While corroded in places, the iron hull retained its structural integrity, allowing researchers to study the submarine’s construction in detail. Artifacts found inside the Hunley, including personal items like Lt. Dixon’s gold coin and a lantern, provided poignant reminders of the men who served aboard.

The discovery of the Hunley also offered new insights into the challenges of early submarine warfare. The cramped and claustrophobic conditions inside the submarine, combined with the physical exertion required to operate it, highlighted the bravery and determination of the crew. While ahead of its time, the submarine’s innovative design also underscored the risks involved in such a daring endeavor.

Scientific Research and Conservation

The conservation of the Hunley has been an ongoing process since its recovery. The submarine is housed in a specially designed water tank at the Warren Lasch Conservation Center, where it is immersed in a solution that prevents further corrosion. The conservation efforts aim to stabilize the submarine’s condition and preserve it for future generations.

One of the key challenges in preserving the Hunley has been the removal of the thick layer of encrustations and sediment that had built up on the submarine’s hull over the years. These encrustations, while protecting the iron from immediate corrosion, also obscured many of the submarine’s features and made it difficult to study.

Conservationists have used various techniques to clean and preserve the Hunley, including chemical treatments, ultrasonic cleaning, and careful manual scraping. These efforts have revealed new details about the submarine’s construction and have helped to preserve the artifacts found inside.

In addition to its historical significance, the Hunley has also provided valuable insights into the science of metal conservation. The techniques developed to preserve the submarine are now being used in other projects around the world, helping to save important cultural and historical artifacts from decay.
