The Submarines that Completely Changed WW2

- The wolf pack of 13 U-boats patrolled the Atlantic when it detected convoy SC 107, comprising 42 ships and an escort of five warships.
It had departed from Canada and was bound for the United Kingdom to deliver valuable supplies to support the war effort.
The commerce raiders went swiftly after them, recruiting the help of three other submarines along the way.
One day later, SC 107 was sighted. Still, the U-boats had to refrain from the attack after Allied aircraft broke off the initial charge of two hunters, destroying them from above.
Nonetheless, when the third night came, the wolf pack attacked with unparalleled coordination, sinking ship after ship to the dismay of the five escorts.
The restless submarines kept isolating the convoy as the hours went by, fully committed to sinking every one of the 42 ships. The question was: did they have enough torpedoes to achieve the task?
I’m passionate about researching U-boats in part because my grandfather severed on a WWI wooden hull subchaser in the North Sea…although he never spoke about it!...This is the best summary of U-boat history I’ve seen...so brief, but nothing of importance left out…was expecting a video specifically on WWII, but you covered the entire history!!...Thanks so much!!!
I got a kick out of seeing Werner Klemperer Col. Klink as the Uboat captain.
👍👍👍
Love the sub episodes. It's among the few times that I get to see Werner Klemperer on screen playing someone other than Colonel Klink
Watching this from Zimbabwe! Your videos keep me informed about unknown history and tactics. Keep it up.
Shout out to Rhodesia's Big Red 1 and the scouts.🙌
Viva la horns of the water buffalo
Come on, join the Commonwealth😅.
The advent of the hedgehog that threw a pattern of depth bombs ahead of the ship was a game changer. As a destroyer would overrun a asdic or sonar target, they would lose contact when the range closed to two hundred yards. That allowed a submarine to change course, go to full speed and get out of range of a depth charge attack. With a hedgehog, the submarine had no chance and the charges were contact fused so they only went off when they hit a submarine directly. This system began being used in late 1942 with widespread adoption in mid 1943. It was a game changer.
The Royle Canadian Navy did a lot of the convoy duty. At the end of the war Canada had the third largest navy in the world.
A largely unknown and surprising fact.
@@joelmacdonald6994 -- we’re not good at tooting our own horn.
What movie was used for clips showing U-Boat crew members. I swear that the Captain is Werner Klemperer, who portrayed Colonel Klink in Hogan's Heroes
You're correct!! I recognized him right away as well.
It is from a German movie about Gunther Prien and the U 47 raiding Scape Flow. The movie itself is on you tube and is quite good and yes it is Colonel Klink playing Prien and he was very good in the role.

It's insane when you stop and think how much diesel, gasoline, and oil went into the oceans during ww2 and the oceans are still able to house fish
Mind blown....lol😮
Not really fish are not that good for you any more. You can only eat one or two meals a week from fresh water sources it's only a matter of time before all the ocean fish are poisonous as well.
@@johncopenhaver4311Japan's gonna dump their nuclear water back in the ocean. From the nuclear reactor accident.
You don't grasp the vastness of the seas. All those things you speak of don't amount to 1/10th of 1% of the oceans. Still quite poisonous though. Mercury in shellfish and some ocean species is already limiting how much we should eat and it's only getting worse
In the deep ocean there is an ecosystem that thrives off of hydrocarbons.
When America entered the war they refused to do sensible things that the Royal Navy suggested. The US losses in the Atlantic were terrible initially.
The gap in air cover in the mid Altantic was the happy zone for German subs. Iceland was occupied to increase the air cover.
The British units based off Derry in Ireland were incredibly important and accounted for about 1/3 of all German ships sunk.
The US had a much easier time with its own subs in the Pacific
When the USA entered the war, the second "happy times" began for the u-boats
Hey I didn't Know Colonel Klink (Werner Klemperer) also was a sub captain! Thought he was a Stalag Gestapo! rofl
Komondant, not Gestapo
POW Stalags were run by the Luftwaffe in most cases not the Gestapo.
How could you know about Hogan's Heros and miss a simple detail like the full name of the place they were held? Luftstalag 13 and that he hated the Gestapo?
well spotted :)

Should also consider a series on the history of museum ships (as people can actually go see them, and they could probably use the revenue for maintenance as many rely on donations). As in, what ships that are now museum ships did while active duty.
Like the U boat in Chicago. That one is incredible to see
I miss mentioning of the development of anti submarine warfare tactics by WATU, which was quite a decisive factor to victory to re-establish domination on the north atlantic from the British side.
You did not mention one of the main reasons the U boats in WW 1 had to change tactics from stopping and sinking on the surface because the British fielded large numbers of Q ships that looked like a merchant ships, but when stopped they suddenly became well armed and fought back. Submarines can not be used even with minimal damage, hence they had no choice but to strike first.
Contrary to the declaration at about the 3:13 point, during WWI the Allies never truly defeated the U-Boat peril, they just neutralized it. January through October of 1918 the U-boats were still averaging sinking around 160 ships per month (compared to a monthly average of 300 in 1917). Also, during WWI a large portion of the U-boat losses were to mines rather than by active measures by escort ships. Sonar/ASDIC were still in their infancy and the U-boats held a small technical advantage over the Allied countermeasures. Convoys were the main tactic that neutralized the U-boat peril in WWI. Escorts generally held the U-boats at bay and once past the U-boats were too slow to catch up - even on the surface where they were much more vulnerable to countermeasures.
WWII was a different story. Up until March 1943 the U-Boats held the day averaging about 100 ships sunk per month. Then around that time frame several weapons/tactics were introduced that did defeat the U-boat peril in WWII - the hedgehog, escort carriers and hunter-killer groups, shipborne and airborne radar became standard, mass institution of the convoy system, DF stations, obtaining Enigma machines and the ability to monitor and decode radio signals, the US industrial might producing more cargo ships than the U-boats could sink, etc. Losses then fell to an average of about 20 ships per month through the end of WWII.
And it wasn't just the prevention of sinkings by the U-boats of ships in the convoys. With the above tactics we were able to route many convoys around the U-boats and send the hunter-killer groups to sink the U-boats at a prodigious rate. Many months more U-boats were sunk than were Allied merchant ships.
Please do a video about Laffey (Benson class destroyer DD-459). For the commenters please note that Dark Seas has done a video about USS Laffey DD-724 Allen M. Sumner-class destroyer not Laffey DD-459 Benson class destroyer which broadsided a Japanese battleship at point blank range.
00.35 and 6:58 Col. Klink was a sub-commander too?
So interesting how warfare devolved from being somewhat "Gentlemanly", like giving the crews time to man the lifeboats to what happened later on, eg, hospital ships , etc, being targeted,
What was Capt Werner Klemperer's record?
Never an escape! 🤣🤣
@@cinibar That he KNEW of, lol........
@@ericblom9568 🤣🤣🤣🤣🤣🤣 Yeah that was a great series! Cheers!
I didn't know that Colonel Klink was a U-boat Captain?😂 Hogan's Heroes is the best
what is the name of the movie with colonel klink in it
weird video. not bad just not a normal sleeperdude vid. i hope everything is alright. love you guys
Boy! Klink looks pissed! ;-)
Why is Kernal Klink In this? ROFL
8:30 wtf is Col. Klink doing in the Navy?
First under water sub on sub kill was a British sub on a German one.
In WW2 - Churchill credited the Royal Navy with doing 50% of the work to win the Battle of the Atlantic, the Royal CANADIAN Navy 49%, and the US Navy with just 1%. In MANY ways - the US Navy was a HINDRANCE to the war effort - ESPECIALLY Admiral King - a man who HATED Britain more than he hated Germany, and who REFUSED to institute Convoys, air patrols or Blackouts - and gave the Germans the SECOND "Happy Time". This ended when Adm King was REMOVED and REPLACED with someone who had more than 2 brain cells, and the Royal Canadian Navy was permitted to escort Convoys along the US Eastern Seaboard. The US Navy was basically USELESS in the Atlantic.
Question 10:14-10:17 . What are the (in the) cylinders behind the conning towers? 10:14
Who knew colonel klink had a dark side 😮
Colonel Klink? ha ha
Talking about Allied aircraft attcking submarines but the accompanying film clip is of He IIIs. Erm, what can I say? Can you not try a bit harder to match the commentary to the visual image?
German u boat warfare was the last to go in the ending of Germany as it was
They weren't outgunned
What was the most valuable cargo lost to subs?
Good Question. Try asking Drachinefel for that.
It was UK developments in Hedgehog weapon systems and millimeter wave radar systems that turned the tide against U Boats in WW2.
Let's not forget the British leigh lite.
@@fredfletcher1370 Yes indeed. Gave those U Boat commanders quite a scare getting lit up in the middle of the night.
That's cute: using Col. Klink...
Please stop using Prussians and Germans interchangeably.

Lets not forget the graveyard of the Atlantic off the coast of NC
Enigma meant nothing without the daily code settings. The German navy’s enigma had 5 rotors instead of the army’s 3.
Twice or more the Allies captured the Kreigsmarine Enigma codebooks without them knowing it had happened, and it did lead to a few 'Wolfpacks' being discovered
If it wasn't for the US, Britain today would be speaking German and flying the swastika.
Don’t let what other countries did interfere with your bloated importance being American. It was nice you finally showed up.
👍👍👍
Time stamp −5:21 That is colonel click.
The German U-boat wolf pack's were very good at sinking ships, but their loses were incredibility high at 75%. The American US navy wolf pack's learned from the German wolf packs and were far greater at sinking much of the Imperial Japanese navy with much lessor loses in US submarines. Regardless of the navies these were sailors fighting for their country and we should respect that. Shalom
They survived pretty well in WW1. I think Germany was a little complacent when WW2 started, and the allies were really tired of eating torpedoes so they got good at hunting them.
god bless their souls
@@792slayer
We had broken the naval enigma code. We knew where their uboats were, and our air coverage had gotten much better.
The Japanese did not put as much emphasis on anti-submarine warfare and didn't escort their convoys nearly as well as the allies did! The Japanese didn't seem to use their subs to strangle supplies off from their enemy like other ww2 nations did, this would be the major factor in the loss ratio between the countries in their sub forces.
@@NikeaTiber we did, eventually, yes. But in the beginning of the second world war we hadn't cracked the enigma yet. I don't think that happened until '42, but I may be wrong on that.
Hahaha Capt Klink was actually Jewish.
Col. Klink.
I see nothing...😉
@@Tzunamii777 No, that was Schultz.
@@Tzunamii777 I remember watching "Hogan's Heroes" as a kid....only in syndication, I was three years old when the last episode aired (1971). I was surprised as I got older at just how accomplished Werner Klemperer (and his parents) were, a sharp contrast from the buffoonish Col Klink.
Werner Klemperer’s Father was Otto Klemperer the famous German Orchestra Maestro and considered an authority on thé Symphonies of Beethoven. Brahms, Bruckner and Mahler. He was Jewish and in 1933 was basically forced to immigrate to the US with his Wife, son Werner and a daughter Johanna. After the war he went to England, Hungary, and Israel conducting orchestras. Otto was Bipolar and suffered from mental issues in life. Son Werner was an accomplished violinist although in his TV role as “Col. Klink” his playing was very bad but that was only part of his role.
The America submerine fleet used the same tactics to attacking marine shipping vessels of Japan naval vessels in the Pacific Oecan. The German U boats were good at tactics in packs to sunking vessels in the middle of the North Atlantic hurting groundings . That changed with Aillies sonar , convey aircarft carriers to protecting convey packs. With the Canada , America navies were important to protecting naval vessel conveys of the North Atlantic conveys to building America lead Aillies armed forces , Air forces Navies of the Aillies using Soctland , England to landing troops, mobile armed divisons with the support of the Aillies Air forces bomber fleets to landing in the north of France and the South of France to starting the long road to freeing Europe of the Nazi armed forces.
Yes and no. The pacific being as large as it was, the pacific wolf packs normally had three boats working together. They would divide the patrol area charts into 3 parts and each take a search area, working largely independently from one another until contact was made with the enemy. The spotting sub would make its attack and then send its contact report to the others after they evaded the escorts, hopefully setting up a scenario where the enemy convoy would run into their pack mate’s area of operations. If it was a big enough convoy, they would send their contact report 1st prior to making their end around run to their initial attack point and giving their pack mates a chance to get into position. At that point the convoys would almost always get cut down to the last ship because the torpedos would start coming in from every direction and rarely ever just a couple per sub. Elliot Laughlin and Eli Reich were masters of the pacific wolf pack techniques.
@@AdmiralYeti8042 very well explained to how the America submarines hurted the Japan maritime japan vessels in the Pacific during World war two.
I hate these clickbait titles. WW2 was not won by some tide-turning battle or some mega wrapon. It was won by US production capability and Soviet wombs. And lack of fuel for Germany.
Of the 40,000 German submarine sailors during WW2 30,000 were killed!
I saw colonel Klink
the guy at 0:44 looks like Colonel Klink.
it was
KLINK!!!
Werner Klemperer
1940: 492 Allied ships sunk as well as 16 KM subs lost. Such a waste of lives and material resources for medieval(!) motives. Just one stat from WWII among so many. btw, what will happen in the Black Sea in 2023? Asking for a friend. 🙂
The Black Sea isn't deep enough for good submarine operations. Firing anything there from a sub would be suicidal in minutes or less. Airborne weapons will rule there; drones, missles, and bombs.
Typical, like Canada had anything to do with the Battle of The Atlantic! Shame! Thumbs down!
now you tell which of your submarine sank that ship for ukraine in black sea
Had they put the effort and materials into uboat production instead of battleships Tirpitz and Bismark they’d have won the battle of the Atlantic
I'm not so sure of this. Germany had 100+ U-Boats at some points in the war, and numerous times there were over 2 dozen U-boats patrolling the convoy shipping lanes. Without effective radar even on a clear day (which was very scarce in the N. Atlantic) they could only see about a dozen miles. The odds of one intercepting a convoy were small, but when they found one the results were devastating for us. A battle fleet was likely to have a strong destroyer escort so U-Boats weren't likely to score well on capital warships after the first torpedo salvo. The big capital ships were also heavily armored and well protected against torpedoes so it took some luck too for an effective hit.
@@P_RO_ tirpitz was about 42000 tons and a type 7 uboat is around 800tons so just in material weight that’s about 50 more uboats. Donitz said if he had 300 boats he could close the Atlantic but couldn’t ger hitlers mind off of the biggest battleship mentality.
@@The67wheelman It wasn't just Hitler and the capital ships. Doenitz knew the war was coming- Hitler asked him how many U-boats he needed before it started and he got half. U-boat production was wide open through most of the war, with bombing of the ports and of materials shipping that kept production down. They had steel but labor was assigned elsewhere adding to the problem. Later on when the reinforced concrete 'sub pens' were being successfully bombed the building effort sort of stopped, as it was clear by then that the naval war had been lost already.
It's truly amazing that Werner Klemperer of Hogan's Hero's was first a U-Boat Captain in WW II. Mr. Klemperer is shown in several segments of the video.
While there are many serious historical inaccuracies in this video, portraying a U.S. TV Series actor as an actual German U-Boat commander is the worst.
This video has zero credibility IMO. Perhaps it is meant as a joke.
It is interesting how you get your facts wrong. You think the Nazis would have a Jewish U-boat commander?
read the comment you mad bastard.. the channel is depicting a fictional television series as fact, where the actor mentioned portrayed a u boat captain@@stevec3526
He is an actor making war movies. Dont you understand that ? So did Kurt Jurgens.
Enigma was given to Brits by Poles in June or July of 1939, three months before war started, together with solution on how to decipher it.
You just repeating the same old anglo-saxon propaganda. You do any research before recording, or you just focus on how dramatic you sound?
The Polish Military Intelligence and resistance made several contributions to the winning of the war, but many of their efforts were frittered away through stupidity and prejdice on the Allied side. Enigma was available commercially before the war so it wasn't a secret, but few actual machines had left Germany before the war started. We credit Alan Turing with figuring out how to break the Enigma code, but the mathematical theory behind that was well-started by Polish mathematicians which saved him at least half a year's time according to his own words.
The Kriegsmarine used a 5-wheel version which with the codes changed daily was unbreakable without some delay involved. Twice or more we captured the list of codewheel settings, and Bletchly Park deciphered some messages. The German Army only used 3 wheels for regular messages and 4 for 'secret' messages which we were able to decipher fairly early on in the war. German Army weather forecasts and reports were always sent in a specific manner, which once discovered made it possible to 'guess' certain words and try corresponding code wheel settings which sometimes resulted in near-real-time decoding. Even long after the war, Kreigsmarine High Command did not believe that Enigma code was breakable; it was so good that some smaller nations used it well into the late 50's before Bletchly Park and Turing's work decoding it became widely known.
Well the Type VII was actualy developed and designed in the netherlands , prototypes and all .
The dutch company even offered a modified Type VII to norway in 1940.
Its funny how people think the germans where the front runners of submarines and yet used dutch designs inovations on their U-boats . where the dutch already had snorkels in 1936 and the germans only adding them in mid and late war .
Would that be bound for England?
