What Killed The Crew Of The Hunley
Fascinating article for Civil War buffs.

https://www.smithsonianmag.com/history/n...gxMjU4MAS2

Quote:One hundred and thirty-six years later, in 2000, in a massive custom-built water tank, archaeologists clad in protective coveralls and wearing respirators sorted patiently through the muck and silt that had slowly filled the hull of the submarine as it lay on the bottom of the ocean floor. Accounts of the Hunley’s sinking had assumed horrific scenes of the men trying to claw their way through the thick iron hatches, or huddled in the fetal position beneath the crew bench in their agony. Sinkings of modern submarines have always resulted in the discovery of the dead clustered near the exits, the result of desperate efforts to escape the cold metal coffins; to sit silently and await one’s own demise simply defies human nature.

The crew of the Hunley, however, looked quite different. Each man was still seated peacefully at his station.

Blast wave.  You know, the kind of thing that Trumpolini just causes little headaches.

Thanks, wasn't current on the resolution of the matter.

Water doesn't compress very much at all, meaning it is a very efficient transmitter of shock waves.

The way her studies and experiments work out they never knew what hit them.  They were sixteen feet away from a 135 pound charge of black powder when it went off.  The specifications in the article are impressive.

That's my take on the situation also. They were just a few yards removed from the explosion.

That's why depth charges work. If you see footage of one going off deep the first thing you see is the shockwave spreading out. Then the big surge of water follows that. The bottom won't move. The lateral movement is face with miles or up to thousands of miles of water that just won't move. But the surface is less than a mile away. So that column of water is disrupted in a rather showy fashion.

It's also why a lot of WWII destroyer casualties happened after sinking when the DCs went off if they hadn't been secured. Shock wave up the rectum would kill swimmers.

I've fired Napoleonic-era muskets with a 100-grain charge of black powder and if you neglect to have it pressed in to your shoulder the recoil beats the hell out of you.  The British version had a brass butt plate and the French used steel.

They learned to have someone "safe" the charges in the rails.

Thanks for sharing this fascinating article. The killing by shockwave is exactly the same thing i have been told earlier this year.

Last summer my team from work went on our annually team event. We went to the catacombs of Darmstadt. The entrance was via a WWII air raid shelter. When we entered, the archaeologist told us that many victims were found in a seemingly "peaceful" state sitting at their places. It was determined that the shockwave of bombs exploding nearby (or falling through air vents) had ruptured their lungs and the people suffocated quickly without showing any signs of external injury, which matches exactly what the article said about the crew of the Hunley.

Traumatic transient over-pressure injury, a term that's probably outdated by now.

It's called "blast lung" nowadays. https://www.ncbi.nlm.nih.gov/pubmed/16531371

There is a reason people use bombs.  They work.

There was a movie called "The Hunley" about ? 20 years ago. Their interpretation was that the attack on the Housatonic caused enough damage to cause it to sink to the bottom unable to rise but with the men still alive within. Not wanting to wait for the air to run out, they agree to open the valves and drown themselves and get it over with. Dramatic for a movie, as they all sing a last song together, but it would account for them all being at their stations.

The article and the black powder testing with the scale model took me back to a childhood as the son of a dynamite blasting man.
Dad and us boys made our own powder and cannons, rockets, mostly bombs. I'll gather my thoughts and start a thread about it, if there is any interest.

Hollywood does so love its drama.

The keel blocks were not released.

https://www.hunley.org/keel-blocks-offer...ppearance/

Quote:“The Hunley designers thought about problems that might arise and I think they understood the need for contingency plans.  The keel blocks are a perfect example of the many innovative design features we see installed on the submarine,” said Michael Scafuri, a Clemson Archaeologist working on the Hunley Project.

This particular emergency function was not used.  The question scientists must now answer is why.  Studies of the human remains show no new injuries to the crew and no signs of panic, suggesting that they did not know they were in trouble until it was too late.

Or, as speculated, they were already dead from the initial blast.
