Hey All! This video is a revamped and remastered version of a previously uploaded video to the channel. I took it down to remove content that had been added accidentally that might have breached copyright so I thought it better to be safe than sorry and re-make the episode with some new goodies in there. Please enjoy :)
Hi Mike, I was just wondering if you have a video about the RMS Carpathia sinking in 1918? I’m writing a book series about ship sinkings in the 20th-21st Century it and I need as many facts as possible :)
2:57 come on, man.... No one has spoken to them, and they had no contact with other islands.. Why make a narrative that they are wary of people because of WWII or whatever? They are just violent. Which is a smart way to be... But it's not OUR fault.
My dad is a Civil War historian and also big in Civil War re-enactments. I had the privilege of going to Charleston for the burial of the Hunley crew. I was just 14-15 at the time but I presented the colors on the first cannon that was fired in the cemetery where they were laid to rest. Pretty cool getting to actually be involved with this. We got to go in and see the Hunley and the contents of what was in the pockets of the soldiers that were pulled from their watery grave.
You have to admit, compliments to whichever officer was able to convince a third crew to get on the submarine that had already killed not just two previous cruise, but it’s creator as well. That’s one hell of an impressive charisma check.
I think the fact they were being economically strangled and desperate for any sort of win also helped. Plus, risky or not, perhaps the honor of crewing and attacking with the first ship of its kind was also tempting.
As a former seafarer with big interest in true maritime history Your broadcasts are most enjoyable 👍Please keep Your speed and course 😎 Greetings from Denmark 🇩🇰
One of the first books I read as a child was about the Hunley. It got me interested in maritime engineering. After decades of visiting the Mary in Long Beach, I never thought I'd end up living here in Charleston... Right next to the Hunley!!! Thanks for the great videos you create!! Long time fan!
I highly recommend visiting the Hunley museum in Charleston if you ever have the chance. One fact they talked about at the museum was that the crew kept a single candle lit inside the vessel. When it went out the crew knew to surface for oxygen
I got to see the Hunley in Charleston in a few years ago. It's a very eerie sight, at the bottom of the pool where it is preserved. Another interesting abandoned ship is the Ocean Dream off the coast of Thailand. I was a passenger on that ship in 1994. I think most of the wreck above the water has been removed now, but there's some pretty cool drone footage. It was one of the original ships from the Love Boat series.
Only my friend, Mike Brady, can make a topically light story like this to be as thoroughly compelling to listen to as his deep dive documentaries. Never disappointed 👍
Given how Hunley was an almost unmitigated disaster, it’s kind of surprising it didn’t effectively kill the sub concept altogether. At least for military usage, for quite some time. Then again maybe the advent of the whitehead/self propelled torpedo helped, since it eliminated the whole ramming/spar torpedo aspect. It doesn’t guarantee you’ll waste an entire sub and crew for maybe sinking 1 enemy ship! By the 1880s Nordenfelt subs had torpedo tubes.
"Given how Hunley was an almost unmitigated disaster, it’s kind of surprising it didn’t effectively kill the sub concept altogether." 1. It was a mere footnote in the history of the American Civil War. Few saw it as a headline disaster. 2. By this time different European nations had already taken the concept of the sub further. Take the French submarine Plongeur for instance. It was designed *before* the Hunley, used a reciprocating engine powered by compressed air to propel itself forward (the Hunley was hand-cranked by humans), had a displacement of 420 tons and was 45 meters long (146 feet). Hunley by comparison was 6,8 tons and 12 meters long (40 feet). While never used in wars it worked in testing, and above all didn't flood and kill its crew. While on display Plongeur actually inspired Jules Verne to write "Twenty Thousands Leagues under the Seas. 3. Different engineers and inventors worked *independently* from each other in different countries. All of them had their own studies and followed their own research along the lines of others before them. The Hunley was just another tangent or blind sidetrack and certainly wasn't the end of the line station. Several parallel projects existed before, during and after the Hunley. "it’s kind of surprising it didn’t effectively kill the sub concept altogether." Not at all. When it comes to inventions there is always new inventors and pioneers willing to develop a concept further. When has a failure of one party *ever* held others back from trying to do better?
@@McLarenMercedesI tend to agree with this. The thing about the Hunley is it proved that underwater warfare was indeed possible. The Germans took what Hunley and those that came before him did and perfected this technology, and put it to good use during the first world war👌
Correction: Submarines were part of warfare as early as 1776, with the submarine “Turtle”. It was built for the future US Navy during the American Revolution, but never saw combat: she was destroyed after sea trials due to the risk of capture. Turtle probably would have been safer than the H.L. Hunley, oddly enough: she was controlled entirely using just three hand cranks and a rudder. One crank propelled the ship forward and backwards, one was used to take her underwater (she was slightly buoyant due to her design), and a third screwed a rudimentary form of mine into the hull of the enemy vessel. Turtle would then have backed off and triggered the mine from a distance by use of a pull-cord attached to the hull (the sub’s own momentum being what pulled the cord). (Interestingly, this also means the Turtle had no ballast tanks: she relied entirely on downward propulsion to remain submerged.) Additionally, as mentioned by others, France was experimenting with submarines extensively at this time, for a variety of purposes: research, warfare, and even salvage operations. In my opinion, Hunley was actually a success: she completed her mission, despite an untrained crew, and they were only killed by something that science didn’t understand at the time. Sinking the Housatonic proved submarine warfare was practical: if a bunch of untrained rebels could sink a full-blown warship with something like Hunley, then what a genuine military could do was limited only by imagination.
The Hunley was *thought* to have killed another crew between the second and third. A test was conducted at pierside with Hunley submerging in place with a full crew, to see how long they could last. Not really sure why actually submerging was necessary, but...they stayed down so long the sentries on the pier reported them as dead only to see the sub rise up an hour or so later and all 8 men emerge somewhat worse for wear. The boat had actually operated exactly as planned, but the men had refused to be the first to signal for an end to the test from fear of being the coward. By the time they did surface there was too little oxygen inside for a candle to stay lit.
That men could outlive the burning of a candle is not as surprising as it might seem. In server (computer) farms, which are installed in windowless secure rooms, they don't typically use normal water sprinkler fire suppression, as water on electronic devices just makes fires worse. Instead they use gas fire suppression. Gas fire suppression relies on the fact that the human body keeps its blood at saturation oxygen levels at all times, therefore breathing depth cannot be controlled from oxygen level. Instead, the body adjusts breathing based on the blood carbon dioxide level, which is normally very low, as is the level of CO2 in the atmosphere - its basically only a trace. This means that you can halve the level of oxygen in the room, and provided you double the concentration of CO2, everybody breathes just fine, though their ability to perform intense exercise would be diminished. But at half oxygen level, most flames go out. I once witnessed a test gas dump in a computer room. I did not have any discomfort, though I did automatically breath a bit deeper. A similar system is used to put out flightdeck electrical fires in aircraft. People have trouble on high mountains where the oxygen pressure is reduced, because the CO2 level is also reduced, so the body exhales CO2 more easily, and thus compensates in the wrong direction and blood oxygen level falls.
@@keithammleter3824 Yes, except you are speaking of a sudden displacement of oxygen. This was gradual, so the oxygen levels in the men's blood would be lowered. Being in a machine room during a fire event is still a very bad idea in general. While toxic Halon is no longer in use, you can still get injured from the suppressive gas as it comes out of the vents extremely cold. You can get cold burns. Perhaps mild frostbite.
@@MGower4465 You are right about the gas coming out cold, but there is not much if any risk of frostbite, as this system is used in rooms containing racks of computers/servers. These both put out lots of heat, typically 1000 watts/sq metre, normally removed by high capacity airconditioning, and comprising lots of metal, about 200 - 500 kg/metre, which acts as heat storage. Usually, some racks house the back up batteries, which have a specific heat about 80% of their volume in water. Also, air normally contains about 80% nitrogen and only 20% oxygen. CO2 is only a trace. To get the oxygen pressure halved, you only need to add inert gas to add about 10% of the total room volume. So the cold is swamped out anyway. Say the gas comes out the vents at 0 C that would lower the room from a typical 25 C to 22.5 C even if the room was empty. The reason why we stayed comfortable was not because it was a sudden dump of gas into the room. It was because human blood is normally saturated with oxygen, and the gas dump includes additional CO2 to make you breath deeper. As we were expecting it, we did notice we breathed deeper, but no discomfort. Human lung capacity is sufficient for vigorous exercise (say walking up an average hill), way greater than needed for just sitting or standing around.
The moment I read the title I KNEW this was the Horace L. Hunley. I read Clive Cussler's book Sea Hunters (or was it Sea Hunters II) where he describes the search an discovery of the vessel. Fascinating stuff. Looking forward to watching this video... I would just LOVE to go see this IRL. But it's a bit far...
Saw the Hunley back in like 2014 or so. Was about 12 or 13 years old at the time. Seeing something that I was obsessed with as a kid in person was magical to me.
strange, awesome video though. I gotta say, had this channel never existed most of this stuff would probably still be hidden away. Thanks for these stories. Keep up the good work
One small correction, the Hunley was never given the CSS designation as she was never part of the Confederate Navy. She was dimply known as the H.L. Hunley.
Yeah, there's a lot of confusion about that point. I've seen it written down on both ways. I think the Hunley museum doesn't call it the "CSS" at the moment, but for many years I think people called it that, so there's a lot of momentum to that name, even if it's true that it wasn't called that during its actual existence.
This is not correct. The Hunley was built by a Confederate officer, and funded by the Confederate government. It was very much a Confederate ship. What is going on here is that people are trying to dissociate the Confederacy’s achievements from the Confederacy itself. The same thing goes on when people call CSS Virginia “the Merrimack” or fail to mention CSS Alabama’s achievements but never fail to mention that she was sunk by the USS Kearsarge.
@@robertgarrard8868 Nope. The Hunley was built by a private individuals and commandeered by the Confederate Army it was never commissioned into the Confederate Navy. Wikipedia is not that hard to use.
Afternoon Sir, Just felt proper to compliment your work once again. I am always learning something and I am grateful for you sharing these with everyone. I watch these with my daughter while making dinner as a great story time and learning piece.
Love the video! I did my master's thesis on American Civil War shipwrecks. I had a whole section dedicated to the Hunley, and it's always nice to see other people taking such an interest in it. The only thing I would note is that Horace Lawson Hunley, for whom the sub was named, was not the designer. The designer was a man named James McClintock. Hunley was primarily the financier, though he was definitely involved in the process of its creation. I just think McClintock should get the credit he's due (though since all three of the subs Hunley paid him to design ultimately sank, maybe he'd be happy to let Hunley take the credit/blame).
CS Hunley has an interesting story , thanks for sharing! Also, there were many bizarre, premature or NOT so great designs from the past, would be great if you made a video about them. What I mean is, for example, the Turtle used in the American Revolution. Or German Seeteufel from 1944.
Your channel has turned me into an ocean liner fan (though I still don't care about the Titanic) and I am replaying the video game Subnautica as I listen to your livestreams. Over the course of an hour at one point I had a sub I was in explode about me twice (and yes that did mean I rebuilt it before taking it out for it to go down in the same way) so I am interested to hear about a submarine with bad luck. It feels appropriate timing wise though the actual events were tragic.
The first I ever heard of the _Hunley_ was from a 1999 film of the same title that I saw in a video rental store as a kid and picked out of whim, and my parents didn't find my choice objectionable since they figured a historical film would be "educational" to some extent. Well, it did get me to look up more about the Hunley from the library and the early 2000s internet, so I guess it kind of was, ultimately.
The SS Mediterranean had a similar fate to the SS America if I remember correctly! I think the only difference is the SS America was being towed to Thailand to be converted into a floating hotel or museum, came uncoupled during a storm, couldn't be retrieved and was simply left to rot! It's like poetry, it rhymes! Love the channel, Mike! Keep doing what you're doing, good Sir!
I often saw Mediterranean Sky in Patras, when I was a kid -along with Mediterranean Sea, which I guess was a sister ship. It was beautifully transformed and looked stunning, at least to my eyes. Many years later I drove by the spot where she's laying. I took some photos, I didn't knew what ship this was because her colors had changed. It was sad to learn that what I admired as a child was rusting in the sea near Elefsis (or Elefsina, as it's now called).
There also were some union submarines! The most famous-ish one is the U.S.S Alligator which sadly never saw action since it sank in 1863 before it could see combat. It’s wreck has never been found.
I've become extremely interested in submarines, and thoroughly enjoyed your coverage of the Hunley! Your erudite presentations are so very interesting! I look forward to everyone of them. Thanks for all your hard work and fascinating content! :)
This was an interesting video as always! I'm always excited to see a new video from you! On the subject of abandoned ships, have you considered doing a video on the SS Alkimos? Considering its remains are still off od the Australian coast near Perth, I'm sure you'll find it to be an interesting rabbit hole to dive into. Depending on your disposition on the Paranormal/Supernatural. It could make for an interesting Holloween special!
Maritime history, engineering, and architecture all in one convenient package. What a complete joy is our friend Mike Brady. If he ever has any children named Greg, Marcia, Peter, Jan, Bobby, or Cindy, that would be perfect. 😉
Depending on the source, the hunley sank up to 7 times. Nautical studies did a video on it, and it's a great watch if you want to laugh way too hard. And before you get upset that so many people died, remember, the south was fighting for slavery (they claim states' rights, but there's one very specific "right" they had in mind) and, to me, a northerners, dead slavery supporting rebels are good ones
Re. City of York/Mediterranean Sky. I was second mate on one of the "big four" of which the York was one. My brother was mate on another. THEY were the York, Exeter, Durban and one other. The picture used was of another of my ships the City of Chester ( or an unknown sisters ship. ). I am Sydney based and admire your channel.
hi, I was wopndering if you would ever consider covering the ferry Sewol sinking. I have seen a few videos on it but I find that they lack something that you have to truley keep my atention. I know its a fairly new disaster, 2015-ish but I feel it might be intresting none the less.
there were also theories that the Hunley's crew simply ran out of air and passed out and never woke up. two things suggest this one being that the sub's wreck seemed to be away from the wreck of the union ship and the other being the Hunley had no damage from any shockwave or explosion. regardless i think passing out in a metal tube under the ocean never to wake up is kind of more terrifying.
I’ve always had great respect for those who volunteer for submarine duty but having seen the Hunley several times that respect doesn’t seem enough. Little more than an iron coffin ⚰️.
You should a video about Chinese grave robbers who are pilfering pre-ww2 ships of their metal all over the world. Pre-ww2 steel is highly valued for making instruments because it was made before the first nuclear bombs were set off.
I tell everyone about my friend; Mike Brady. Sometimes they ask: "How does he kow?" What? "That you're his friend"? It's obvious! HE. JUST. KNOWS. Good seeing you Mike, a d terrific video, as always!
As a Charlestonian it always makes me happy when a part of our history ends up making it into the international spotlight. I don't think I've seen the Hunley since I was a child but even as a kid I remember thinking that climbing into that thing was not the best idea, I have no idea how that ever got launched. Thank you for another great video!
I live near Charleston, and somehow I haven't visited the Hunley yet. We have a lot of other maritime history too, including Civil War fortifications, two WWII museum ships and the hull of a freighter that sank and was towed into shallow water.
You should do a video about the SS Fort Mercer and the SS Pendleton and the rescue efforts of both ships. There’s a movie about the SS Pendleton and the rescue of the crew (The Finest Hours). Both ships sank in the same storm in the same waters both split in half and they were sister ships.
Mr. Brady, I love your channel, but, since it is dedicated to nautical information, and very good one, please refer to the sides of a vessel as port and starboard. Thank you, Al
hey mike, i think if the sources were provided in the description or pinned comment in a plain text it would be nice and accessible for folks to do some further reading
You know, there's a lot of folklore here in the US concerning Civil War ghosts, but if you want to see a REAL Civil War ghost visit the Hunley! It's as real as they come. Interestingly, and unless this has changed, the Hunley is actually now the property of the US Navy. At the end of the Civil War all Confederate nautical assets ( Even though Hunley was never officially CSS Hunley) became US Navy property just as the Confederate Army's assets became the property of the US Army / War Department. I haven't heard the Navy has given up ownership so if anyone knows for certain please correct me.

@@robertgarrard8868 Nope. The Hunley was built by a private individuals and commandeered by the Confederate Army it was never commissioned into the Confederate Navy. Wikipedia is not that hard to use.
Worth a re-watch these shipwreck videos are very cool 😎 Thanks!
Afternoon Sir, Just felt proper to compliment your work once again. I am always learning something and I am grateful for you sharing these with everyone. I watch these with my daughter while making dinner as a great story time and learning piece.
I made it for a change! Yay! Thanks for the content Mike!
Good morning, my friend Mike Brady!!! Greetings from the U.S.!!! 🇺🇸 👍✌️
Love the video! I did my master's thesis on American Civil War shipwrecks. I had a whole section dedicated to the Hunley, and it's always nice to see other people taking such an interest in it.
The only thing I would note is that Horace Lawson Hunley, for whom the sub was named, was not the designer. The designer was a man named James McClintock. Hunley was primarily the financier, though he was definitely involved in the process of its creation. I just think McClintock should get the credit he's due (though since all three of the subs Hunley paid him to design ultimately sank, maybe he'd be happy to let Hunley take the credit/blame).
I remember this one! I enjoyed it at the time, and again now!
I'm surprised you didn't mention who headed the expedition that found the Hunley - author Clive Cussler, the writer of 'Raise The Titanic'.
CS Hunley has an interesting story , thanks for sharing!
Also, there were many bizarre, premature or NOT so great designs from the past, would be great if you made a video about them.
What I mean is, for example, the Turtle used in the American Revolution. Or German Seeteufel from 1944.
Shoutout 1UP crew!!!
I saw it in Charleston while visiting my grandmother.
1up crew! Legends!
Your channel has turned me into an ocean liner fan (though I still don't care about the Titanic) and I am replaying the video game Subnautica as I listen to your livestreams. Over the course of an hour at one point I had a sub I was in explode about me twice (and yes that did mean I rebuilt it before taking it out for it to go down in the same way) so I am interested to hear about a submarine with bad luck. It feels appropriate timing wise though the actual events were tragic.
The first I ever heard of the _Hunley_ was from a 1999 film of the same title that I saw in a video rental store as a kid and picked out of whim, and my parents didn't find my choice objectionable since they figured a historical film would be "educational" to some extent.
Well, it did get me to look up more about the Hunley from the library and the early 2000s internet, so I guess it kind of was, ultimately.
You can just hear the banjo coming from the hunley.
I love this channel!!
The SS Mediterranean had a similar fate to the SS America if I remember correctly! I think the only difference is the SS America was being towed to Thailand to be converted into a floating hotel or museum, came uncoupled during a storm, couldn't be retrieved and was simply left to rot! It's like poetry, it rhymes!
Love the channel, Mike! Keep doing what you're doing, good Sir!
Also, I believe there is a photo floating around of both America (Alfredoss) and Mediterranean Sky laid up together in Eleusis Bay
The Hunley? Sign me up!
I often saw Mediterranean Sky in Patras, when I was a kid -along with Mediterranean Sea, which I guess was a sister ship. It was beautifully transformed and looked stunning, at least to my eyes. Many years later I drove by the spot where she's laying. I took some photos, I didn't knew what ship this was because her colors had changed. It was sad to learn that what I admired as a child was rusting in the sea near Elefsis (or Elefsina, as it's now called).
Very good. I’m surprised you’ve put out so much lately. It’s been hard to catch up. I think I’m almost there.
I would love to see you do a video on the Edmund Fitzgerald!
ONE UNITED POWER at the end absolutely *cheffs kiss*
There also were some union submarines! The most famous-ish one is the U.S.S Alligator which sadly never saw action since it sank in 1863 before it could see combat. It’s wreck has never been found.
the life of the Hunley is absolutely hilarious. Thanks for sharing the story of the craziest part of the american civil war
Ngl ! Mike you're so handsome ✨🤓❤️ and you're voice is so elegant....
Wow. what a conversion!
Thanks Mike!🙂👍👍👏👏
I've become extremely interested in submarines, and thoroughly enjoyed your coverage of the Hunley! Your erudite presentations are so very interesting! I look forward to everyone of them. Thanks for all your hard work and fascinating content! :)
Well done thanks for your research
I loved that video thx Mike and as always stay safe
A submarine that sinks... how novel..... lol. Just kidding, another great vid Mike! 😊
Merry Christmas to you and yours
Good job !!! Always like your videos. Please make a video on IJN Yamato. Love from India
Txs for another fantastic video.i was expecting RMS Queen Elizabeth in the video lol xx
I appreciate the effort you put into your videos. Subscribed
I live maybe 40 minutes away from Charleston I might go to the museum and visit it.
This was an interesting video as always! I'm always excited to see a new video from you!
On the subject of abandoned ships, have you considered doing a video on the SS Alkimos? Considering its remains are still off od the Australian coast near Perth, I'm sure you'll find it to be an interesting rabbit hole to dive into. Depending on your disposition on the Paranormal/Supernatural. It could make for an interesting Holloween special!
Thank you kindly Mike for correctly pronouncing Mobile, Alabama 😊 it's amazing to me how many people mistakingly pronounce it mo-bye-L.
Always love these videos. And the mug and shirt look great that I ordered. Thanks for your professionalism and quality!
You know how terrible a shipwreck story is going to be when you hear something like “Luckily for them, the storm did not abate”.
Another great video
Maritime history, engineering, and architecture all in one convenient package. What a complete joy is our friend Mike Brady.
If he ever has any children named Greg, Marcia, Peter, Jan, Bobby, or Cindy, that would be perfect. 😉
Depending on the source, the hunley sank up to 7 times. Nautical studies did a video on it, and it's a great watch if you want to laugh way too hard. And before you get upset that so many people died, remember, the south was fighting for slavery (they claim states' rights, but there's one very specific "right" they had in mind) and, to me, a northerners, dead slavery supporting rebels are good ones
Re. City of York/Mediterranean Sky. I was second mate on one of the "big four" of which the York was one. My brother was mate on another. THEY were the York, Exeter, Durban and one other.
The picture used was of another of my ships the City of Chester ( or an unknown sisters ship. ). I am Sydney based and admire your channel.
hi, I was wopndering if you would ever consider covering the ferry Sewol sinking. I have seen a few videos on it but I find that they lack something that you have to truley keep my atention. I know its a fairly new disaster, 2015-ish but I feel it might be intresting none the less.
The Hunley sounded like a real Payne in the neck.
there were also theories that the Hunley's crew simply ran out of air and passed out and never woke up. two things suggest this one being that the sub's wreck seemed to be away from the wreck of the union ship and the other being the Hunley had no damage from any shockwave or explosion. regardless i think passing out in a metal tube under the ocean never to wake up is kind of more terrifying.
I remember being briefly taught about the Hunley, but not that it had sank three times prior.
I rather miss the Edwardian attire. But still an amazing video.
I’ve always had great respect for those who volunteer for submarine duty but having seen the Hunley several times that respect doesn’t seem enough. Little more than an iron coffin ⚰️.
well done 369k subs
Request: could you make a video about ‘ocean liners’ (yachts) of Royal families/governments?
You should a video about Chinese grave robbers who are pilfering pre-ww2 ships of their metal all over the world. Pre-ww2 steel is highly valued for making instruments because it was made before the first nuclear bombs were set off.
Cool, I just got a book about the recovery of the Hunley
I tell everyone about my friend; Mike Brady. Sometimes they ask: "How does he kow?" What? "That you're his friend"?
It's obvious!
HE. JUST. KNOWS.
Good seeing you Mike, a d terrific video, as always!
As a Charlestonian it always makes me happy when a part of our history ends up making it into the international spotlight. I don't think I've seen the Hunley since I was a child but even as a kid I remember thinking that climbing into that thing was not the best idea, I have no idea how that ever got launched. Thank you for another great video!
H.L. Hunley. When the submarine IS the screen door.
what does the "1UP" on the side of the mediterranean sky mean? was that there before it sank?
I live near Charleston, and somehow I haven't visited the Hunley yet. We have a lot of other maritime history too, including Civil War fortifications, two WWII museum ships and the hull of a freighter that sank and was towed into shallow water.
You should do a video about the SS Fort Mercer and the SS Pendleton and the rescue efforts of both ships. There’s a movie about the SS Pendleton and the rescue of the crew (The Finest Hours). Both ships sank in the same storm in the same waters both split in half and they were sister ships.
I have been inside the holland 1, the entire interior was all rotted out and only three people i think could go in at one time.
The docs on the Sentinelese are fascinating .Stone age people in 2023
the primrose crashing on that island was like their Roswell.
Interesting as always, thank you again.
Mr. Brady, I love your channel, but, since it is dedicated to nautical information, and very good one, please refer to the sides of a vessel as port and starboard. Thank you, Al
Can you make an episode on Costa Concordia? For it was fairly recent and really interesting.
good job. you said Mobile correctly lol
In Charleston it’s widely considered bad luck to touch the Hunly ..
hey mike, i think if the sources were provided in the description or pinned comment in a plain text it would be nice and accessible for folks to do some further reading
You know, there's a lot of folklore here in the US concerning Civil War ghosts, but if you want to see a REAL Civil War ghost visit the Hunley! It's as real as they come.
Interestingly, and unless this has changed, the Hunley is actually now the property of the US Navy. At the end of the Civil War all Confederate nautical assets ( Even though Hunley was never officially CSS Hunley) became US Navy property just as the Confederate Army's assets became the property of the US Army / War Department. I haven't heard the Navy has given up ownership so if anyone knows for certain please correct me.
