A Forgotten Genius Beneath the Waves
History often praises the loudest voices, but sometimes the most remarkable stories are buried deep beneath the surface. For more than a century, textbooks have credited Horace Lawson Hunley, a Confederate lawyer, as the man behind America’s first submarine — the H.L. Hunley. But recent research tells a very different story, one that exposes how racism and deliberate erasure robbed a Black engineer of his rightful place in history. His name was Benjamin — and though his full identity was lost, his legacy as the true mind behind the Hunley is finally rising to the surface.

A Nation Divided, Innovation Born
The 1860s were a time of chaos and desperation. The Civil War tore the United States in two, and the Confederate South struggled to overcome the Union’s powerful naval blockade. In that moment of crisis, southern leaders turned to innovation, seeking a machine that could destroy Union ships from beneath the water. Thus, the idea of a submarine — a radical concept for its time — became their last hope.

While Horace Hunley financed the project and lent his name to it, he wasn’t the engineer behind the invention. The real builders were enslaved and free Black craftsmen — blacksmiths, carpenters, and metalworkers — who brought centuries of African craftsmanship and technical skill to life under brutal conditions.

Black Labor: The Hidden Force Behind Confederate Industry
Contrary to what many Civil War accounts suggest, the South’s economy and industry were powered not just by enslaved labor, but by enslaved intellect. Across foundries and shipyards, Black men worked as machinists, mechanics, and artisans. They built ships, railroads, and even war machines. Their understanding of metalwork, pressure systems, and design was unmatched — and often far superior to their white supervisors.

When Confederate engineers began assembling the Hunley, it was these enslaved workers who shaped the iron plates, forged the rivets, and crafted the hand-cranked propulsion system. Their expertise in metallurgy and physics transformed an impossible dream into a functioning underwater vessel. Yet, their contributions were never acknowledged. Their names were erased, their genius hidden behind the myth of white invention.

The Shadow Engineer: Benjamin’s Legacy
Among these forgotten builders was a man known only as Benjamin. Oral histories passed down through African-American families in Louisiana describe him as a skilled blacksmith and mechanic, a man with a natural grasp of pressure systems and underwater mechanics. Long before the Hunley project began, he had sketched crude designs of underwater vessels, inspired by both African traditions of watercraft and his own mechanical intuition.

Benjamin is believed to have developed crucial components for the Hunley — including its air circulation system and the hand-cranked propulsion mechanism that made the vessel move silently beneath the water’s surface. White overseers mocked his ideas in public but relied on them in secret. His fingerprints — literal and intellectual — are embedded in every iron plate of that submarine.

Built in Secrecy, Rebuilt in Suffering
The construction of the Hunley was grueling and tragic. The submarine sank multiple times during testing, each time taking lives with it. Each time it was raised, repaired, and rebuilt — by enslaved hands, in silence. They worked in the shadows, under threat, crafting a weapon that would change naval warfare forever but would never bear their names.

On February 17, 1864, the Hunley made history when it successfully sank the Union warship USS Housatonic, becoming the first submarine to destroy an enemy vessel in combat. But the triumph was short-lived — the Hunley never resurfaced. All eight men aboard perished, including Horace Hunley himself.

For decades afterward, southern historians celebrated Hunley as a Confederate hero. The truth — that an enslaved Black engineer helped create the machine — was buried as deeply as the submarine itself.

Erased From the Record
The story of Benjamin and his fellow Black craftsmen fits a broader pattern in American history — a pattern of systematic erasure. Enslaved inventors like Benjamin Montgomery, who designed a revolutionary steamboat propeller, and Thomas Jennings, who patented dry cleaning, were exceptions in a world where most Black innovators were denied patents and recognition.

When the Hunley was rediscovered and raised from the ocean floor in 2000, experts marveled at its advanced design — its intricate ballast tanks, airtight compartments, and efficient propulsion system. Yet again, official reports credited Hunley and his white associates, ignoring the likelihood that the design reflected the knowledge and labor of enslaved Black engineers. Racism didn’t just steal wages — it stole legacies.

Why History Hid the Truth
Why would such an extraordinary story be hidden? Because acknowledging it would shatter the racist narrative that underpinned southern pride. The postwar “Lost Cause” myth painted the Confederacy as noble and its enslaved people as passive and inferior. Admitting that enslaved Black men created one of the South’s greatest technological triumphs would have exposed that lie.

It’s easier to glorify a white lawyer than to credit an enslaved genius. And so, history was rewritten — by those who held the pens.

Iron, Blood, and Memory
Every rivet in the Hunley is a testament to Black craftsmanship. Every crank, every weld, bears the mark of the enslaved men who built it under the lash and in silence. The vessel’s endurance, even after multiple sinkings, speaks to their mastery. They were not simply laborers — they were engineers, inventors, and visionaries whose brilliance transcended the chains that bound them.

The story of Benjamin reminds us that genius often blooms in the darkest corners — and that oppression cannot kill creativity.

The Truth That Refuses to Sink
Today, historians and archaeologists are slowly piecing together the real story, listening to descendants whose families preserved oral traditions about ancestors who helped “build the iron fish.” While official documents may never reveal Benjamin’s full name, his legacy lives in every conversation that reclaims his contribution.

The Hunley wasn’t just a Confederate war machine. It was a monument — one built on pain, brilliance, and the unacknowledged genius of Black America.

Conclusion: Lifting the Submerged Truth
The story of America’s first submarine is more than a tale of innovation; it’s a mirror reflecting the buried truths of a nation built on both slavery and genius. Benjamin’s mind changed the course of naval warfare, yet history refused to speak his name. But silence doesn’t erase brilliance — it only delays its recognition.

The H.L. Hunley may have sunk beneath the waves, but the truth about who truly built it is finally rising. And as we rewrite the story, we honor the brilliance that history tried so hard to drown — the genius of the Black engineer who gave America its first submarine.
