imagine that oh crap moment when both of them realized that their periscopes were looking right at each other

Fun Fact: In order to attack U-864, Lieutenant Launders had to devise a firing solution against an actively maneuvering target on a 3D plane, which at the time was considered to be mathematically impossible under realistic circumstances. And yet, Launders was able to pull it off and HMS Venturer became the only submarine in history to sink another submarine unaided while both were submerged.

I bet Mark owns his own U boat

One of the most amazing WW2 submarine vs submarine actions is from 1942 in the Baltic Sea when Finnish submarine Vetehinen ambushed Soviet ShCh-305. Vetehinen had been tracking the Soviet submarine during the night, when it suddenly surfaced. The distance was too close, and the torpedoes fired by Vetehinen went under the keel of the target. The Soviets tried a crash dive to safety, but the captain of Vetehinen ordered ramming speed with deck guns blazing. Vetehinen rammed ShCh-305 in front of the conning tower and shortly after the Soviet sub sank beneath the waves with all hands lost. The wreck of ShCh-305 was found in 2007.

It's been 80 years and that uboat is still killing things around it.

Love your work Mr Felton. My dad was a Submariner in the mid to late 60'. He was on two old WW2 subs. He's gonna love this video. Thank you for your great programs. Just wonderful. Thank you again.

'Sharks and Little Fish' by Wolfgang Ott is a chilling, authentic book about his u-boat service in WWII.

Mark,I have a VHS tapes here at home and it has the captain talking about this sub on sub engagement.Thanks as always for posting the video.

This is going to be juicy! Watch the ads to support the Dr. Please viewers

Me: doing something Mark: posts a video Me: *important work stops*

Dr. Felton paints such an great picture with words, I was able to imagine everything as if I was watching a movie.

Thank you for not drowning the presentation under a deluge of ads.

Marks main channel is going to hit a million subs soon. Some of the best content there is

War is hell, that's for sure. Mark's delivery does these events, the tension in the situations, the courage and sacrifice of those involved, appropriate justice

Imagine being a passenger on this..........I'd want my money back!

Keep up the good work! When will they give you a tv show!?

This is the only place for learning on KZfaq that is safe from ads.

Mark....another incredibly detailed....highly informative ...perfectly written (and narrated) segment.... The best channel of its kind

The submarine shown is U-505, a Type IXC u-boot captured on June 4, 1944, now located at the Museum of Science and Industry in Chicago, Illinois. As a member, I’d encourage anyone to come; it’s an amazing exhibit with excellent on-board tours.

Yes! I’ve been waiting for this story to be mentioned!!! Nice, Dr. Felton!

God rest their souls... I hope it was quick for them...

There's one other submarine duel, on 5 November 1942, Finnish submarine Vetehinen rammed Soviet submarine ShCh-305 and sank it.

I'm really enjoying these War Stories, I'm self employed and these are great to listen to while I work. Thanks for all the great content Mark!

I'm here within an hour of it being posted. My best yet!

This is a special moment for me, because for the first time, I already knew a topic to the very detail. But nice to hear the story again

Imagine being on that British sub in shallow enemy waters with orders to sit and observe an enemy submarine base with your periscope up in broad daylight!That must have been nerve wrecking... One mission and you would ho home with grey hair I reckon.

Great story. Thanks Sir Mark. I enjoy learning about individual events that make up the war.

Love your content! Always learning something new from both your chamnels! Keep them coming!!

Facinating. I'd never heard of this. As always, an outstanding story. Thank you.

I know that during World War II there were several duels between submarines where one of the combatants was sunk by the other, perhaps the most famous case being the U.S.S. Corvina sunk by the Japanese submarine I-176 south of Truk on November 16, 1944, just prior to the invasion of the Gilbert Islands. So, in all these cases, the sunken submarine was always sailing on the surface?

Two to watch tonight, thanks again Mark

Mar Felton's war stories are such a great source of interesting histories that they can't be missed, thanks Mark 👍

another great video! Thanks

Great content as always

Thanks, I've been asking for more submarine content

Fantastic stuff, so well written and delivered. Thank you Mr Felton

I love your video channel, but these audio stories are absolutely awesome. Great to listen to while I'm puttering around the house doing chores on a Saturday morning.

Another great episode thanks!

Excellent Dr. Felton.

Thanks for another great story that keeps these lost stories alive

Great story. Love your video and now audio!

Congrats Doctor Felton!

Good Job Mark!

Great! I didna know of this encounter. Thank you!

Fascinating account of a neglected episode, Mark. Thanks.

It would really neat to learn more about Allied submarines, and how they compared to German U-boats in function and effectiveness.

Wow, great story that never made it to the big or small screen. Thanks Mark.

Wow! Incredible story that was new information for me. Very well done and told, as always, Mark. I always appreciate your work and all that you do to share history with the world. Please keep the outstanding videos coming and God bless you and your family, my friend!

Very well done. Like your spin on the whole story.

GREAT STORY DR. FELTON !!! BRAVO 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏

Well I guess work can wait for 10 minutes 😊. Thank you 🙏 Dr. Felton.

Great Job!

Always love your Videos!!!! One of my Favourite channels, hands down... Much Love from the Space Coast!!!! ( East Coast Florida )....

Thank you Mark Felton. This great story remonds me of the novel and movie The Hunt for Red October.

Another unique military feat: Crew chief of an Air America helicopter shoots down a North Vietnamese Colt AN2 biplane over the Plain of Jars in Laos for the only rotary wing air-to-air victory in history. Why not a video on that, Doc?

I have read about this encounter but, as always, it is well worth another visit.

Thankyou Mark! I loved this look back into "somewhat forgotten" or "overlooked" history. Interesting point about the mercury too! With all the emphasis on todays polution by large corporations being a real factual problem....we tend to overlook something even more disturbing that took place for years both prior and after WW2 around the worlds oceans. Highly volitule and environmentally deadly materials carried by sea vessels of all types. Vessels sunk is just one factor considering what happens 50, 60,70+ years later....rust, corrosion releasing into hhe ocean in areas we don't even know about. I'll go one farther....radio active materials. Lost, sunk or dumped in containers now leaking....you get the idea. Even if the costs were waived of any cleanup operations like Norway's mercury problem. Others can never be accomplished by any means with the best technology available. Truly... Pandora's box....with a very, very rusted lock....and lid.🕵🤔🙏😇🖖✌😍😘🦅🦅

Only time in History that KZfaq was used to LISTEN a story from WW2....and what a terrefying and dramatic one!!! 👏👏👏🤗

Thank you Mark very cool 😎

Oh hey, background image is the hometown -hotdog- boat! U-505!

Would be awesome if you would be uploading these as podcasts. Thanks for the always high quality.

Who are the people that “dislike” these informative videos? What is there to “dislike”?

There are a couple of excellent programs on this incident. One was on PBS. Having the good doctors narration is icing on the cake.

Great videos, and I believe not only was that the only time in WW2 that occurred, but also in the history of all naval warfare where one submerged vessel killed another submerged vessel. Back then they were not guided either which made this feat even more insane.

Excellent!

Brilliantly researched story, well told!

Snorkelen was a Dutch invention, captured in 1940

Great, thanks! Always enjoy your work. By February, 1945, Allied airborne search radar had advanced to the point that a U-boat snorkel could be detected. Running submerged no longer offered much protection, especially since lookouts could not be posted.

Another outstanding video!!! Please keep the Kriegsmarine videos coming!! Thank you, this is my favorite channel on KZfaq!

Always the most informative and interesting of Videos.

Excellent

Thanks! new sub.

Excellent documentary.

Three subjects EVEN Mark has yet to make a video about 1. (Friendly) War over Hans Island. Canada vs. Denmark WAR 2. Pistol Shrimp helping the Allies Win the Naval War in the Pacific. 3. Operation Flowers are Blooming (Seychelles Rugby Team Deception War)

Interesting story Mark.

Excellent.

Vielen Dank, mein Freund..!

theres a great video of this dual on youtube some where'ss its really well told story similar to Mark's

Love the photos of U-505. It would be pretty awesome to run into Dr. Felton at a museum in chicago.

Thank you

WW2's Only Underwater Duel. Very interesting. First I've heard of it. Any other underwater duels occur at any other point in history?

I live quite near the place where the U-boat sank, the Island it rests next to is named "Fedje" and is on the west coast of Norway, north from Bergen by many kilometers. It's interesting to hear more about how this event occurred and the reasons for a U-boat to carry a vast amount of mercury.

Thank you as i always wondered if there was ever such an account of an event regarding submarine vs submarine. I have never heard much about British submarines and always wondered about their effectiveness against the uboats, you would of thought that the uboat captains were very experienced & would have took some serious tactics in cornering one, i geuss as the war drew to an end that these experienced captains were a dying breed & with the younger inexperienced captains didn't really stand a chance against a seasoned battle hardened captain. I am amazed that the Mercury containers are still there rotting away & breaking down into the sea bed, terrible. Great account Mark, thanks.

Anyone remember when the U-505 was outside? This was the only reason I wanted to go to Science and Industry as a kid. So great to be able to get a better look at it now that it's exhibited like this.

Great and horrific War Story. Thanks Marc. I would like to hear a general history on British submarines. I can't find much out there.

Just excellent.

I seen this on Smithosan Channel a while back. Really interesting.

They should name High schools after Mark Felton

He should upload this to Deezer and Spotify

Too good 👏👏👏👏

Now that you mention it I have heard about the leaking mercury.

Absolutely love your content. If I were to give a bit of what I hope is constructive criticism-- this is kind of hard to follow. I think this is the first videos of yours that I've found the time line of the battle a bit confusing.

Hometown shoutout for the U505 photo.

UBoats are beautiful, they look what they are, sleek and deadly. It never occurred to me that they had anchors

That was badass

I hope the "WW2 in real time" channel mentions these videos when to get to these parts of ww2.

Yet in so many WW 2 movies, sub vs sub combat was considered the norm.

A wonderful sideshow story of the uboat War thank you.

I seem to recall reading that this was the first use of passive sonar target motion analysis, where the sound guy was plotting the zigzag pattern using TMA and got torpedoes on target by predicting the next turn. I can't seem to find a source now, however.

THANKS fot putting Imperial measurements in Dr Felton. I try to be 'bilingual' in I Imperial & metric , but it's difficult to visualise in metric, for me; having grown up with imperial inches, feet, & miles.
