- It’s one of the few sub-to-sub duels during WW2.
The German submarine U-864 was part of top-secret Operation Caesar, a mission to transport German jet fighter parts and 67 tons of mercury to Japan.
British submarine HMS Venturer was sent to intercept. HMS Venturer fired all four bow torpedo tubes at the U-boat's predicted position.
U-864 split in two and sank with all hands off the Norwegian coast

No matter what side of the war you fought on, explosive decompression is a horrible way to die.
Not explosive decompression, BUT WAS EXPLOSIVE COMPRESSION, atmospheric pressure inside the Sub while underwater, suddenly splits into two parts, instant 300 Feet of Water Pressure.
Don’t you die instantly and won’t feel a thing? Tried to research it online and nothing.
@@krisdunwoody7037s 300 ft really deep enough to generate _explosive_ decompression?
In not sure it is.
Edit: I'm not deleting this comment, but I was wrong.
300ft of depth is about 8 atmospheres, which I've just discovered is absolutely deep enough to generate explosive reactions at this depth.
I suppose for those submariners who caught the explosive blast square in the face, they wouldn't have felt a thing as they got squished, but the poor buggers in the rear, behind the blast doors and sinking down in their sealed tombs must have been horrifying..
Apparently it took those poor buggers in the Russian submarine, Kursk, about 6 days to die after they sank to the sea floor at a similar depth, despite rescue divers getting close enough them to tap morse code into the sunken submarines' hull and get a response from the trapped submariners.
In ww2 though, no chance of that. They were trapped as soon as the sub broke it's hull, if the blast didn't kill them, and I cannot imagine what they went through.
@@NiSiochainGanSaoirse Kursk was horrible, stuff of nightmares for the survivors of initial blasts. Frankly im impressed that literally a full load of torpedoes detonates and only blows open the bow. You'd think the whole sub would be pieces from that
explosive decompression is somewhat quick. think about being stuck on the bottom at 500 feet with 40 of oxygen left. plenty of food and water, and maybe 3 hours of drugs for 30 crewman.
This is the only time in history that a submarine destroyed another submarine all while submerged.
True story
Also without homing torpedo's
Wild to think!
A United States Sub sunk a Japanese sub. Both were initially surfaced until they dove and repeatedly rose and dove. But I mean you are correct. This is the only time both combatants stayed below water for the entire fight.
Only the proven story. Soviets invented one more story which was found out as a fake after the war was over and archives became available. I mean the submerged duel M-175 with inconnu sub which has shoot 10 torpedoes at the M-175. Or not invented- the Soviet sub danced not with enemy torpedoes, but with a coastal motor launch and the sound of the explosion of own two torpedoes was an explosion due to meeting the rocks in a Norwegian Fjord where the dance was held.
Sub crews had a tough row. I couldn’t do it…
I couldn't either Paul. I'm too tall for one thing, but besides that I don't think my nerves could stand it.
Being an infantryman was enough for me. At least I could breathe fresh air and walk without banging my head on everything around me.
Greetings from North Carolina btw... respect to the British and Deutsche submariners
Even though my father was in the American submarine Corp of that time, it affects me when they say lost with all hands, it's a lot of guys dying at once, and a horrible death.
I was talking to a US Navy submariner from the 1950s. He shocked me when he said sub guys were not given tests to determine if they could withstand the strain. They were simply chosen quite randomly. Just wow.
@@davidvalensi8616 my grandfather served on three boats during WW2 in the Pacific.
@@mikestanley9176 My father served on the Thresher, Tuna, and the Roncador. The conning tower of the Roncador is now a monument in California.
The Mercury has begun to migrate out of its containment and is currently polluting the sea bottom and fish in that area. This U-boat is more deadly now than it was as a weapon of war.
Dam I wonder where you got that from word for word
@@renald4115 always astonishes me when people watch one CZcams short and think they’re einstein😂 dude commented what the CZcams short said word for word.
According to the Norwegian government 470000m²= 5059038ft² of seabed is polluted ..we are still waiting for the government to take action and do something, but 80 years goes so fast
@@torerasmussen4282 do nothing. That sub is a war grave.
Blame the Allies for that : if U - 864 had not been torpedoed, this would never have happened!
The balls these men had to live in a steel tube under crushing depths of water anxious about something as a small as a pipe bursting killing you. The anxiety would kill me
The balls were crushed too.
WW2 subs could take alot of damage before they sank, the engineering was impressive for the time.
All that mercury just laying on the bottom
And now it's slowly seeping out because their metal containers are corroding.
Exactly
What about Fukushima..?? That’s been leaking Thousands of TONS of RADIOACTIVE WASTE EVERYDAY SINCE 2011…
Apparently it’s now leaking due to corrosion of the storage vessels.
Germany should be forced to pay for the salvage of the mercury.
Can we just appreciate how HARD this is.
Imagine you’re in a pitch black gymnasium with four javelins. And you have to hit a human sized target anywhere in that 3 dimensional space. Which is changing course, depth and speed and you only know where it is every 15 seconds.
Isn’t a human sized target though U Boats are 87 metres long
@@Tobez1 JEEZ you must have been good at physics, it was far further away than a gym's length.
@@givenfirstnamefamilyfirstn3935 my bad I was really high 😭
It's like echolocation. You don't know exactly where he his but you can create a rough sphere of his presence and throw your javelins in the sphere.
Trickshot
67 tonnes of mercury?!? - what did the Japanese need that for? 🤔
Making high explosives.
@@CS-zn6pp Thank you 😊
Actually fulminate of mercury specifically is used in the primers of ammunition.
It is speculated that by sending supplies to the Japanese would lengthen the Pacific War and keep the allies occupied while the Nazis made their getaways to South America.
They were right
@@markjawitz6363 Very Interesting - thank you 😉
The Germans wanted to help japan produce atomic bombs against the US in the pacific
The clever bit was predicting which direction the U-boat would dodge when it heard the first torpedoes coming; and sending the 4th torp thataway.
going deep and steering from the torpedo was the standard way of dodging further fire for all submarines during ww2, and the captain of HMS Venturer knew that. so he had some idea of where he should aim, giving him more chances of hitting the enemy then blind firing.
I believe it was the only sub to sub duel ever?
Yes, only one verified between two submerged subs.
There were plenty of duels between subs during the war. About 2 dozen U-boats were sunk by Allied, (mostly British,) subs during the war.
At least one US Sub was sunk by a Japanese sub, and several Japanese subs were sunk by US and British subs.
But in every battle, the sub that was sunk, was on the surface. This was the only time in history a submerged sub, sank another submerged sub.
It is the only incidence in history in which a submerged submarine sank another submerged submarine via torpedo strike.
An incredible feat to do, particularly at that time given the maths involved in predicting the enemies path, compared to a surface duel, where you don’t need to worry about calculating depth when aiming and firing.
Us sub sank jap sub as well
@@theMull90 like others have said and I personally think it warrants the clarification, it's the only *confirmed* one.
Claims of other occurrences but will likely never be possible to confirm
No doubt, the British Sub commander knew his math!
Maths, surely
@@lumunolumuno7501 " 'Ee knew 'is maffs"
@@oldkingcrow777 ?
@@oldkingcrow777 shush
Well, the navigator knows math. There is likely another officer setting a firing solution. I acknowledge that it could have been the commander but I don’t assume that.
You don't hear a lot about the British submarine service. Would be interesting to hear more stories!
There are plenty on Google alone, people just don’t care.
They're known as the silent service for a reason.
I mean theres mueseums in Britain about it but no one cares really
'Unbroken' (1953) by Alastair Mars is a good start.
Most British sub boats that sank were due to accidents and mines.
And the steel containers with the mercury have already begun to rust through and leak. It could be a really bad deal.
They are planning to bury the wreck under 5000ton of clay in the next 18 months but the German government is objecting to it.
I think it was kept in glass containers.
Too bad mercury is on the periodic table, and is a natural element
@@jacobreisser8034 wrong
This is the first time I've actually heard someone cover a operation that a british submarine was involved.
Excellent marksmanship from the British sub especially given how slow those unguided torpedoes were
When you zig but the enemy knew you were also gonna zag
I could never be a submariner. Respect to ANYONE with balls large enough to get in one no matter the country.
No shit you couldn’t
@Jumping Spooders damn, you have a bad day at work or something? Everything alright at home? I'm not sure why you would reply like that. If it wasn't caused by a built-up rage or similar, might wanna get that checked out.
The Venturer crew wondering why they keep getting kill notifications even after WW2
You gotta wonder how many unexploded torpedos there is at the bottom of the ocean!
A shit ton. The Germans used over 1000 uboats alone, that’s like an insane amount of torpedos also German torpedos sucked and didn’t explode a lot
I’m betting the ocean bottom is haunted
Now you know where all that mercury came from in your weekly Tuna serving!
Very instructing, keep up the good work bro I'll be glad if I would find more of your shorts randomly. Imma sub
That is an extremely tough shot to hit with the tech of the time!
It's hard to believe but each shot was calculated in order to predict possible trajectories of the German sub. You can imagine how complex the calculations were as both subs were moving in 3 dimensional space and at different velocities. This also had to be done at speed, without the benefit of modern electronic calculators.
Not sure about this one, but many had a machine you plug numbers into for a firing solution to be giving. Still, everything had to be correct and a lot of it was prediction.
@@JackSmith-hx8zhnot really hard to believe you think they just guessed? 😂
Respect to all these people, that would be such a horrible death
no wonder tuna is so high in Mercury
I am worried of all that mercury going to sea water
Good news is you don't need to worry about the possibility of it happening.... the bad news is that's because it's already happening.
And all those mercury free in the ocean...
The british commander was a 24 yr old math genius who used his big brain to compute an unprecedented 3D firing solution to neutralize the hun sub en.m.wikipedia.org/wiki/Jimmy_Launders
Thank you I read the story based on your lead. Fascinating. Wonderful so many Nazis were killed so brutally, as they intended to do to all the rest of us.
MATHS
I am not afraid of heights, spiders, snakes my point is I don't have any phobias except for claustrophobia. I am pretty sure my heart would explode the moment they closed the hatch on one of those U-boats or submarines. I give massive respect to any of those men on either side that have the balls to go into battle in a submarine. Respect to all submariners!!

I was of the understanding that it was the first and only successful sub to sub torpedo attack
67 tons of mercury? At the bottom of the ocean
It started leaking out
Nobody going to talk about the red Mercury onboard that the only predicted use was for the German bell engine (anti gravity) for their secret project. Those sub engines ran on diesel and electric.
67 tons of Mercury? A TRUE TICKING TIME BOMB after nearly 80 years submerged in salt water.
Submariners, each one man among men! No matter who you served, Ya fellas had GRIT!
Seems to me it would be quick.
I'm impressed they hit with a dumbfire torpedo
Programmed constant heading and depth, not all that dumb.
@@givenfirstnamefamilyfirstn3935 Dumbfire still entails that they have no control once it leaves the tube
If it was a US sub there would be 5 different Hollywood films
So you're telling me there's 67 tons of mercury on the ocean floor now? That's not good.
I read recently that the steel canisters that house the mercury are starting to break down.
That does not bode well for the Norwegian ecosystem as the Mercury will have polluted.
Mercury is denser than water and it will just sink to the bottom.
I believe it was near the Northern Russian coast in the Arctic circle, not in Norwegian waters. There was a plan to bury the wreckage in hundreds of tons of sand to contain and bury the mercury but idk if they ever did it.
slow way to die if your stuck in a sealed compartment, fast way to die if youre not.
Buy the fast pass free to stand in the section the torpedo hits for instantaneous death
Bro they managed to hit it, without knowing where it was, nor at what depth, with only 4 "little" torpedoes (compared to the submarines' size).
It wasn't a chance hit, either. One of the submariners was a mathematician. He calculated possible positions of the German submarine based on its last known position and likely trajectories and speed. It was mind boggling mathematics done on the hoof. He had to take into account the relative speed and direction in 3 dimensions of both subs and the speed and trajectory of the torpedoes. There weren't any electronic calculators.
Thanks for your videos
Thank you for the kind words, Parker! Glad you like them!
Average World of Warships submarines 1v1
All I can think about is that video of the ocean with the caption “submarine battle”
Dude...
Mercury!!! Tht means that the sub is more dangerous today than when it wasn't sunk on the bottom of the ocean floor.
Everybody gangsta until they realised the submarine was filled with mercury💀
Thats some damn good shooting!
A British sub sank a U-boat...
Meanwhile Azur Lane: After 5 years, still no Royal subs. 😭
270,680 dollars of mercury is just chillin down there.
Unrecovered Mercury.
I couldn’t imagine that feeling…
Duel? Lol, it was an ambush.
WAR IS NO JOKE AND IT IS HELL INDEED. 😮
My those men soles rest in peace
Do you mean souls, or are you concerned for their shoes? 😂
That's one of my biggest fears to die in a submarine or drown in a sinking boat
Thats bonding
When you can’t know, if you serve in your coffin or temporary home.
My grandad was on submarines in WW2, every time he left a sub, it sank.
The Submarine version of *Bad* Luck Chuck
@@oldkingcrow777 No, the presence of the grandad kept the submarine alive, it was after he departed that the subs luck ran out. He may have been the good luck charm.
Now all that mercury is leaking into the sea making an ecological disaster.
Absolutely love submarine movies! WWII submarine movies! Those guys were so brave! That's what America should be made of!
Now you cant eat the fish
Shooting at something you can't see with auto-aim turned off.
They could see the snorkel
That's how 60 tons of mercury got in the water and spoiled all the fishes
The German submarines (wolf pack) did horrific damage to the British cargo ships of the Atlantic Convoys in WW2. It's awful the way these submariners died, but think of all the thousands of British and American lives that were the target of these men. 😢🇬🇧
The Germans pchu'ed around and found out.
Fun fact: the mercury is killing every thing in the radius
150 meters is less than 500 feet. Fix your script
Ever think of submarine movements translates movements in outer Space?
You failed to mention that the mercury is leaking into the ocean
All that mercury...no wonder eating fish is a bad plan!
Can't imagine what those moments were like. Horrifying.
Creating a massive mercury contamination
67 tons of Mercury very interesting
If any country would do something like this it would be them Brits, and they didn't care for submarines as they called them un gentleman like, because they didn't give the opposition a fair chance, just pop up shoot at a ship with loads of people on and then slip away
Is that why tuna has high concentration of mercury?
Jet fighter parts? LoLz, no full of mercury that is now leaking
It's hard to imagine blindly firing super expensive torpedoes. They were the equivalent of $350k (estimate $25,000 US, £ would be less) each and not normally squandered in wild shooting. They would have to guess at depth, range, speed, direction and azimuth. That's a lot of uncertainty to spray fish that cost so much. I just wonder if there's more to the story than this CZcams version.
. . . and is now an ecological nightmare as the metal drums containing the mercury reach a point of corrosion where the toxic mercury is leaking into the local environment and being consumed by fish and other sea life, which is in turn a problem for the local fishermen. And, y'know, the environment.
And that, my children, is why northsea fish contains high levels of mercury to this day.
You hear about dilution? The north sea is about 54 by ten to the power of fifteen litres, that is 54 million billion litres.
I was actually just reading about this so it's cool to see it elsewhere, unfortunately the steel containers holding the mercury have deteriorated so much that's become a severe environmental hazard 😢
Another video said 73 tons of mercury. It was made by some guys that have an unmanned underwater rig and they salvage ships. Just curious how you guys have conflicting info on the cargo. I’m not saying who is right or wrong by any means just letting you know.
67 tons of mercury?? What damage has that caused?
you people don't realize how sick of a shot this is for a WW2 diesel sub. what a crazy captain, what the hell was he thinking taking these shots? this shot is insane. there's a reason it only happened ONCE!
edit: i found out the torpedos used were Mark VIII*. those are UNGUIDED TORPEDOS, NO freaking WAY!!!! furthermore, the other sub was already doing EVASIVE maneuvers!!! this is the single most impressive shot anyone has taken, using ANY weapon.. ever.
Why were they transporting 67 tons of mercury?
I'm guessing to make mercury Funimate
@@george2113 What's that?
I Googled it.used as an igniter for other things. It's still bad sunk in 500ft of salt water, it won't be good. 😢
Mercury was used in the manufacture of explosives.
@@george2113 you mean mercury fulminate as in primers?
To the Abyss it went, how terrifying to go down to the depths.
And the mercury is leaking now
I hate how nobody remembers the uss batfish did it first
Can't imagine being blown up underwater gotta be the scariest death
Quick though
Water entering at 8-9 times atmospheric pressure would be like a turbo mincing machine, anyone at the dry far ends would be ablaze from the ignition temperature of the compressed air but their lower skulls would have imploded and their rib-cages including their spines would be instantly crushed inwards into a large Frankfurter.
They could only dive to 300 feet down.
Love seeing the same content on dozens of channels…no one is original anymore.
not really a duel, more a hunt
It is considered the most dangerous wreck
Get the physics right guys.
A 300ft depth is 10 atmospheres - not 8.
Plus, as the subs internal pressure is 1 atmosphere any break in its hull will cause a rapid compression - not decompression.
From a professional diver 👍
It’s a pity they won’t clean the mercury wreckage that this particular uboat was carrying because it’s poisoning the water
It's not that far from Bergen to the wreck.. worst thing is that they haven't even started the clean up yet cause the vessel and its cargo is too unstable..
And 67 tons of mercury went right into the ocean , 😮
If I had to choose my deaths as a soldier, this is easily in my top three. Very frightening way to die
Japanese kamikaze with jet fighters would have been an insane sight lol
