U-455, The Mystery of the Lost Submarine | FULL DOCUMENTARY

In Summer 2008, a mysterious submarine is discovered off the coast of Italy at 120 meters deep. For Lorenzo del Veneziano, an underwater marine archeologist, it is an amazing sight. The submarine is intact! It stands almost vertically at the bottom of the sea, it's hull stuck in the sediment.
What is the story of this ship, why is it here?
By uncovering the mystery of its origins we will retrace the incredible story of U-455, a German warship that fought every marine battle against the Allies, from the Baltic Sea, to the Atlantic and then finally the Mediterranean where it now rests. An extraordinary underwater adventure and an ambitious historical investigation.
Documentary: U-455, THE MYSTERY OF THE LOST SUBMARINE
Directed by: Stéphane Bégoin
Production: ZED & ECPAD for ARTE

I think the sailors in the submarine would like to he remembered, they made the ultimate sacrifice after all. Most people wouldn't even think of doing something like that to save their own mother. These men did if for free, for love of their country. Therefore it stands to reason they would not like to be forgotten..

[@Crashed131963]

Then the Liberty ship where made where the US could build more of them then the Germans could make torpedoes . Germany could never win the numbers game .

[@oculusangelicus8978]

True, America Knew there were German U-boats off their Coast, but did nothing because they were afraid it would cause panic among American citizens, so they did nothing. Germany had spies in the American Government and military, because they had records of American servicemen who were serving in the Airforce, Navy and Army. One African American who was a pilot in the Redtails was shot down over Germany and when he was being interrogated, they had a copy of his dossier page for page! So German spies were inside of the American government or Military and sent their gatherings of information back to Germany through the U-boats, that was the only way it could have happened. Its obvious there were a lot of Germans in America that were still loyal to the Fatherland, brings out a whole new experience doesn't it? Seems like while the Japanese Americans were treated all as traitors they should have been locking up anyone with a German last name as well, huh? You have to really wonder how many of the Japanese citizens would have betrayed America like obviously Germans were. Perhaps the Government knew about the spies and were waiting for the proper time to quietly remove them and send them for a ride in a black car out into the countryside, who knows. But it was obvious that they knew, because shortly after being capture that Redtail pilot had an opportunity to escape and made good on it. when he returned to base he told his superiors about his knowledge and about an exact copy of his dossier in the hands of the Gestapo. and that little tidbit of info MUST have made it's way back stateside.

Same old u boat 🚢

[@felixthecleaner8843]

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.

[@jackharrison6771]

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.

[@robinwells8879]

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?

[@Softail77us]

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

[@salvagedb2470]

End bit was the Best ..good Vid.

[@anthonylowder6687]

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

[@ihateemael]

the German historian said 30 feet of the stern was missing, presumably blown off by a mine.

[@Gelbwurst]

@@ihateemael In German he literally said that the 30 feet are not "visible", which means, he cannot see them. That is different from not being there phyisically, the translation given by the english voice is basically wrong, although the german expert explained later that he think an explosion may have taken place. The angle of the boat is very similiar to a submarine wreck in the eastern sea close to finland that also hit a mine while underway. It did not cut off any part of the boat but caused a catastrophiy flooding letting the nose dive down and dig itself deep into the mud.

[@ihateemael]

@@Gelbwurst ok thx.

[@gooberdoober2286]

30 feet of a tube of steel going into the sea floor backwards? How tough do you think these boats were or how soft the sea floor is. The boat is not nose first so propellers and rudders would not allow the boat to slip into the sand on the sea floor so I think your assertion that 30 feet of submarine is under the sand is not correct. They gave a pretty believable theory of an unknown mine field that the boat captain was not privy to. His boat hits a mine , possibly igniting their own torpedoes (u455 had five torpedo tubes including a stern torpedo tube), and because air is trapped in the front section, the boat lands in a 45 degree angle.

[@ericferguson850]

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

[@Jens-Viper-Nobel]

The correct term would be a British port since men from both England, Scotland, Wales and Ireland served in the British navy, and the navy had the waters from the Channel to south of the Faroes as their home waters. And arguably, Scotland was part of the British empire at the time. Last I heard, they still are.

[@ericferguson850]

Jens, I agree with what you have said regarding Great Britain and the British Empire. Scotland is a proud part of Great Britain. My initial comment was relating to lazy research and generisation by the authors of the video.

[@pseudonym745]

Wish I was there now...

[@Jens-Viper-Nobel]

@@ericferguson850I don't think they are neccesarily lazy, but nations outside the commonwealth do show a tendency to generalise the term Great Britain and the term England to mean the same thing although England, Scotland, Wales and Northern Ireland are essentially 4 different entities united under the English crown. As a Dane, I make that distinction myself because I have Scottish roots from a few centuries back and does not consider Scotland to be a part of England. They are 2 different nations as far as I am concerned, albeit united under the British commonwealth. But let's see for how long it will last considering the ever present desire to become truly independent again.

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

[@stephendezouzsa]

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

[@joewebb4836]

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.

[@peterbamforth6453]

Superb documentory Not sure of this reposters narration though.

[@romanmartinez6458]

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

[@oculusangelicus8978]

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'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?
