U-455 was lost with all hands after hitting a mine in a German minefield off the coast of Genoa. Unless the crew knew that their boat had entered a minefield, the detonation and the subsequent flooding and sinking of the vessel would have come as a total surprise for the crew, unlike being attacked by depth charge from an allied ship or aircraft. One minute they were sailing untroubled, the next they were fighting for their lives. The "lucky" ones died immediately in the deadly explosion. May the crew of U-455 rest in eternal peace.

The most beautiful part is people from all over Europe work together to discover and preserve the darkest time when we were at each other's throats. May the fallen rest in peace!

It was so incredible that seventy years after it went down in 120 metres of sea, one of the former crew views the wreck from a 21st-century submarine.

Well done! Giving the submariner in the end the chance to say goodbye was so moving!

Das boot!...my friends out there.. will show you exactly what it's like if you've not seen it....nerves of steel..hardship..and rewards if you survived...no matter what side you are on a submariner is a special kind of warrior...to be admired for his bravery in this kind of warfare..thanks for your excellent documentry, it was wonderful to watch the powers of research work its magic.

The narrator should know that nobody used " grenades " against U Boats..they're called Depth Charges !

One cannot avoid the thoughts and reaction of the old submariner; clearly recalling his one time comrades. I'm just speechless. And the very idea, that some might have survived the explosion; to be left in the remaining section; trapped on the bottom, leaves me speechless.

The view of the U 455 by a fomer crew member must have been a sad experience. War is so cruel. No more wars. We must prevent wars.

30:18 Americas new strategy?? Convoys, those things the British had been using in WW1 that when suggested to the USA were ignored until shipping losses were too high.

I really like that the explorers invited the veteran to see the ship.

Isn't the so-called American strategy of convoys really the British strategy that they adopted ?

that was well worth taking the time to investigate this thoroughly. Am well impressed with the research done and especially the help of two ex mariners who actually served on this boat. One of the best U Boat vids I've seen so far. A great piece of work indeed.

30.000 German submariners lost their lives. But how many Allied sailors lost their lives to these submarines?

Posted 6 hrs ago? I could swear I've already seen it. It's the one off Italy with it's nose up in the air

When the submariner asks if the British and the Americans don't have become so smart and powerful that their only concern is with German submarines, he is saying something that no matter what service, coming to grips with the sheer size and magnitude of the American involvement in the war and its seemingly endless supplies of everything was a shock to their souls. At the time that Hitler declared war on the United States Gobbles told the German people that all America could so was to make refrigerators and toasters. My dad played a part in the anti submarine war along the Atlantic coast while my mother's father was a submariner in WW1, one of the first sonar operators aboard a submarine, the K2. In WW2, he was a sub contractor for the New York firm which built Army training camps and after finished Camp Van Dorn, he took my grandmother and they went to work at Higgins Industries, building mainly landing craft, PT boats and other type vessels. My grandmother was Andrew Higgins' personal stenographer. Higgins was tremendous in promoting his industry, with each new PT boat, he gave the crew a shortwave radio so they could listen to be entertained rather than using Navy radios. He presented each crewman with a large multipage booklet commemorating the gift, which I have one of. He also handed out photos of himself sitting on the side of a PT boat with a naval ensign flying in the breeze behind him which looked like an old time 1776 naval commander's hat. It was by accident but looked so good that it became his main PR photo, of which I had one. Also photos of PT boats in formation during runs on Lake Ponchartrain. Then there are the lapel pins of PT boats as well as the cloisonne Red Cross pins given when workers spend free time helping prepare bandages, etc. I know the Germans did the same thing, they had all sorts of awards for war work, etc. So Higgins was not doing something unheard of.

This was one of the best War Submariner Documentaries. Very well done.

The end of the movie is very touching.

An extraordinarily well put together documentary about an intriguing investigation, also managing to capture the human tragedy of this war story, regardless of which side one was on. And more compelling than many of the movies available to watch as well. Thank you for this excellent upload SLICE. Much appreciated. 👍👍👍👍👍

submaritors all brave men today men and woman have no fear

After an hour and a half of surveillance of the wreck with the submersible it discovered the cause but had no footage of the damage nor any good footage of the boat at all. I expected more and better footage of the sub. Very moving scene with the vet seeing his old boat and best friends entombed,sad but ironic because of the death and suffering they caused as well. War is hell.

A first-class and moving documentary. Thank you for posting!

amazing documentary with great story telling. The scenes of the sub are amazing and wish there were more. The fish obviously happy for it.

The fact that Mr Swartz struggles to look at the wreck is deeply poignant. I would suggest that the partial extension of the periscope is an internal shock pressure related thing and the fact that the sail hatch is actually open suggests some survivors attempted escape. That the bow is remarkably still buoyant would suggest that no escape was attempted from the torpedo loading hatch. Could all the survivors have made exit via the sails double hatch airlock only to succumb to the pressure?

This is the BEST doco on U-boats and their life. So well done. Thankyou.

The video was cut short. SLICE Full Doc is not so 'full'. The original is on the youtube somewhere.. They didn't cut much.

Peace to the fallen, only they have seen the end of war.

Great documentary. Thanks for posting.

It’s unlikely that the mine completely severed the U-455s stern completely off and they never did explain why she’s at a 45 degree angle. I believe that the mine flooded the stern section and at the angle she sank she hit the bottom and the mass of the flooded section of the boat buried the stern 30 feet or more into the silt thereby acting as an anchor holding the boat upright at a 45 degree angle as she is today

Another banging doco! Thanks europe!

This was a great document and very interesting - thank you

This is technical diving using trimix. It is specialised diving.

I love this documentary Salute to brave sailors of U Boat dedicated and devotion to duty

very good documentary. I had seen them before and am curious about what they will discover on the next U boat

If that was the Pacific, they would have already recycled it, people and all. They loaded missiles into the torpedo tubes? Underwater grenades? Get the terminology right....

Scapa Flow is an English port? Last time I was there it was up at Orkney Island in Scotland.

I own the exact document shown at 13:33. It was the 'soldbuch' of Adam Mueller who is also shown during one of the cuts in this program when examining the photo album. Tragic end for such a storied crew.

"English port of Scapa Flow" Scapa Flow is in the Orkney Islands, North of Scotland

Amazing 😮

Almost all of the German U-boots were sung as sea in combat, the vast majority of Survivors from U-boats were men who were transferred or were taken from U-boots either for other duties, promotions, illnesses or for a myriad other reasons, some subs were captured because they were unable to dive or were driven to the surface, those were the lucky sailors, the rest died a cold watery death. The luckier of the dead were sunk to depths where the vessel imploded and all were killed instantly but many, like U-455 likely survived the initial explosion only to run out of oxygen in the cold darkness or drown. I think it was cruel for them to put this survivor into the Remora and let him see the state of his sub, because the condition of the Sub would have told him everything he would have needed to know how his komeraden died. you could see that he had to look away when, I imagine, he saw the tail end of the sub completely gone. But a German mine was not powerful enough to blow off the tail of a Submarine, it would have had to have help, with the aft torpedoes being set off as well, That would have allowed the aft to be torn away, with the explosion of the torpedoes from inside. And because of that, the men in this Sub were likely killed almost instantly. If torpedoes detonated inside of the hull, the pressure of the explosion would have ripped all the way through the interior of the vessel, because they were in friendly harbor/waters, the sections of the sub would not be closed like in combat, the whole sub would have been open to the explosion so the men were either dead, or knocked out and because the sea would have rushed in almost immediately, and the angle of the boat so great, the men would have toppled to the lower part of the ship, into the sea, and drowned while unconscious

I couldn't get MXC Replay out of my head listening to the English overdub.

Very moving at the end

American strategy was the convoy system. Nope, the Brits had to insist on it being adopted.

It was more than 70 years ago if you go back to 1944 that’s 80 😊

So, is every U-Boat accounted for except for 3 U-Boats? If that's right then that's pretty good knowing that the U.S & allies did a good job for the history books.

Superb documentory Not sure of this reposters narration though.

This documentary reminiscence of Das Boot movie. Even the closing about the data of submariners who survived & died.

Major flooding in the Aft torpedo room/ Engine equipment room ?? I think the Germans had something equivalent to the Monson Lung and many should have escaped.

The narrator calling sailors soldiers is a major error.

What is "underwater grenades"?

Underwater grenades shouldn’t that be depth charges?

AXEL Mann, das Heck steckt im Dreck und ist nicht "wegexplodiert". Es gibt einige Schiffe die fast senkrecht im Dreck stecken, das sollte man vllt. wissen wenn man sowas macht. Das ist mir ein bisschen peinlich.

The RN and RCN sunk most of the U-boats in the North Atlantic.

This vid was uploaded two years ago on the Timeline channel.

It is history of U-Boot-Seekrieg. NOT specially about U -455 and WHY it sank.... A bit boring...

There's a movie called U571, it was filmed here in Malta.😊

There is no way this U boat hit a mine , the hatch on the conning tower is open , and U boats entered friendly bases on the surface , and how can he say the stern is missing when its most likely under the seabed mud , it looks to me like this sub was scuttled by it's crew

It's not the City Hall, but obviously, the New Reich Chancellery.

God bless everyone that died on all sides I wish will all can make peace not war hopefully are new generation can get it right and learn to make peace we are all gods people no matter where we can from we just got different beliefs let's not let us stop that from loving each other

Iron coffins as one surviving Uboat commander described The subs!

IN WATERS DEEP In ocean wastes no poppies grow, No crosses stand in ordered row, There young hearts sleep...beneath the wave... The spirited, the good, the brave, But stars a constant vigil keep, For them who lie beneath the deep. 'Tis true you cannot kneel in prayer On certain spot and think, "He's there." But you can to the ocean go... See whitecaps marching row on row; Know one for him will always ride... In and out...with every tide. And when your span of life is passed, He'll meet you at the "Captain's Mast." And they who mourn on distant shore For sailors who'll come home no more, Can dry their tears and pray for these Who rest beneath the heaving seas... For stars that shine and winds that blow And white caps marching row on row. And they can never lonely be For when they lived...they chose the sea. -- Eileen Mahoney

The English Port of Scapa Flow!!!! What nonsense

I couldnt do it.. no way am i getting inside a device that goes underwater yet man can still breathe and walk somewhat freely on flat ground (submarine floor), the whole thing is unnatural. The men and women that perform this job have bigger balls than me and thats for certain.

If Luc and Marc wanted to know which sub it was why didn't they just read the title of the video?

Poor German dude :( His heart was all broke.

Depth charges were used against submerged uboats by allied warships. Not grenades.

Sad

Scapa Flow is not English. Get your facts right.

Look at capone syphilis

They're depth charges,not grenades. Smh.

"The submarine is intact!" But it's men are all shattered. The closing 5 minutes prove the most poignant of the video...an ostensibly "fortunate survivor" has lived long enough for the dogs of war to find and maul him at his end. No 'pride' could survive that last blow. God help him.

23:33 USA entering this part of the war didn't change anything, other then a "Second Happy time"for the U-boats of the Kriegsmarine. No escort ships like the british convoys had, and Wolfpacks of U-boats having a field day, UK WRENS tactical manouvres made the ultimate decision, not America entering, that it a total myth..

Fantastic documentary! Well researched, well told, well filmed story. Thanks for sharing!

In the start only clubs had pokies and as legislated profits were returned to the community. These venues appealed to the older generation and the younger couldn’t care less. When Pubs got pokies a generation of young men get caught by the “one armed bandits” sad to hear weekly they put their entire wages through. Whats inexcusable is hotels pocketing the profit because with addiction they are profiting off someone’s peril. Karma is coming their way. Whoever’s idea it was to allow pokies in pubs ruined many young lives and has forever stained our culture. Karma will get them too.

Then the brave u-boat shot it's missiles. 1,2,3 grenades aimed at the heroic u-boat! Are you really that simple?

Ooh man. The Outer hatch is open. That means the crew tried to swim for it. That would be a horrible position to be in. Unless someone recently opened the hatch, but I doubt thats the case, it looks to rusty

When they flushed the toilet trap stayed open, happens sometimes really

Please, God or whomever.. No More Fighting 😥🙏

i don`t think that 30,000 dead German submariners was a lot, the amount of soldiers that got killed by bombing & tanks was well over 30,000 probably 100 of thousands.?

Narrating over music is just stupid

seeing the mob praising the crew of a submarine commander who no doubt murdered so many innocent sailors makes my skin crawl so see how cruel they were at that time in history.

Wow 3 .5 hours to swim back up to the surface .

I doubt anyone aboard would still be alive. They'd be well into their 90's by now.

French bunker restorers …. yes the obvious people to identify a WW2 Kriegsmarine sub 😌

WAR SUCKS ON ALL SIDES..

Ye ye... And what about RAF propaganda for the strategic bomber command? We all know for the Butcher Haris.....

I have 2 questions: Why is there netting all around the sub? Why was the conning tower access hatch open?

looollll, did they really go down with that tiny sissors to cut all of that netting? That's pathetic really

Dear Earthlings; with the emphasis*on Dear, for their passed lives have got a meaning to how to deal with people in stiring the ship called Earth to a sustainable Future with respect to those who've fallen in attempts by sending people to the frontlines with mostly no avail to improve the world we're living in unless you change course of making history in a positive* way by defending the good to get rid of the bad idea's. My gratitude to those who given their lives Sincerely Yours @ the Shrewd.🤔🤨😊

I have already seen this. It's an old video.

Scissors ✂️ 😂😂

Hands up who didn't know you could scuba dive 400 feet without popping

Roberto looks just like Daniel Craig.

Summary: Nazi gold was not there

Divers at 400 feet. Hmmm

Amazing that there was a survivor that was able to see full circle and the fate of his friends and boat! Sadly there's no such things as happy endings after a total war, but this bitter sweet moment is something that is a example of unnecessary death with wars and the price of humanity it reeps needlessly. I'm not total antiwar, but given a good enough reason like ww2, there was no getting out of such things without spilling blood. You can't play offense and defense with friends and enemies and believe you are neutral..... Eventually you will piss one off and games on then for us too, but it's evident we have yet to lean this? As we keep supporting Ukraine, Eventually this is going to bite us hard! Stupid people making dumb decisions based upon their greed!

LMAO Well, that's too bad, we can't see the number. But it's a nice day at least." "Indeed, it is a nice day." "So who wants some pizza?" "I love you." No matter where you go in the world, pizza will always make it better.

Why is everything English, the English this, the English that?, I thought Scotland won it with 2 bombs.

Should stop using outdated inofficial measurements like feet and pounds in documentaries. Start educating your people.

You need to get actual translators, this robot crap doesn't cut the mustard.

Keep your powder dry.
