They Perished In A 19th-Century Submarine, And Their Cause Of Death Remains A Mystery

This 40-foot-long vessel made history as the first submarine to successfully sink an enemy ship during battle.

In 1864, the H.L. Hunley went down like a bad bet, and when it surfaced in 2000, the horror was still sitting in the details. Over a century and a half later, the crew’s sudden deaths, with no obvious physical injuries, turned one of the most famous submarine disasters into a stubborn mystery.

Researchers raised the sub and found minimal hull damage, so the usual suspects did not line up neatly. Even after they opened the crew compartment, they still could not pin down why everyone died so fast. Was it a collision and a leak, a brutal oxygen miscalculation, or even a bullet that struck the captain through a porthole and left the rest stranded?

Then there’s the wild theory that the torpedo explosion that sank the USS Housatonic might have killed the Hunley crew too.

Over 150 years later, the cause of the men's sudden deaths without physical injuries remains a mystery.

Several theories explain the Hunley's sinking: a collision with a ship causing a leak, a miscalculation of oxygen levels leading to asphyxiation, or a bullet killing the captain through the porthole, leaving the crew stranded.

Some scientists think the torpedo explosion that sank the USS Housatonic also killed its crew.

In a study in PLOS ONE, biomechanist Rachel Lance tested a mini Hunley model's explosion in North Carolina, revealing a shock wave that suggests the same occurred with the actual Hunley.

Lance believes the wave impacted every crew member, leading to lung damage and fatal pulmonary hemorrhage. She mentioned that such a forceful wave, akin to explosives experienced in the field, results in unmistakable and instant harm.

The whole case gets weirder because the Hunley came up from the ocean in 2000 with minimal hull damage, so the crew’s deaths did not match the wreck’s appearance.

It’s like the friend who booked a luxury stay and refused to split costs, triggering silent treatment.

People keep circling back to the same dark possibilities, from a collision with a ship causing a leak to oxygen levels dropping fast enough to suffocate everyone.

And then the USS Housatonic theory enters the chat, with the idea that the torpedo blast could have done lethal damage even if the sub itself looked only slightly battered.

In PLOS ONE, Rachel Lance’s mini Hunley explosion tests showed a shock wave strong enough to suggest the blast hit every crew member, not just the structure.

While the exact circumstances surrounding the sinking of the H.L. Hunley may never be fully elucidated, ongoing research and scientific inquiry continue to shed light on this enduring maritime mystery.

The efforts of researchers like Rachel Lance underscore the importance of exploring new avenues of investigation to unravel the secrets of the past and honor the memory of those who perished aboard the historic submarine.

The Hunley is gone, but the blast, the leak, or the porthole shot still won’t stop haunting the crew’s final moment.

Wait, this “best friend” secret about a sentimental gift turned into a real blowup, read what happened after they hid the lost gift.
