Wolfpack Tactics: How U-boats decimated Allied Convoys

German Wolfpack and U-boat Tactics during the Second World War posed a serious threat to Allied shipping in the Battle of the Atlantic. This video explores the concept of wolfpack tactics and also how individual submarines of the Kriegsmarine attacked merchant shipping.

Since the question came up a few times: Why not sink the escorts first? Answered on my second Channel: kzbin.info/www/bejne/fZ2Wkp5-Zr99irM

[@christopherthrawn1333]

Great question. Why didn't they develop faster torpedoes to destroy or disable them first? Even later on when they were getting sunk fast later in the war?

[@FanaticProductions]

A good video. Some details where new for me. One remark about Karl Dönitz sons. The soruce (Milner, Marc: The Battle of the Atlantic) you quote at 19:32 mentions, that Karl Dönitz only (!) son died in May 1943. He had two sons. Peter Dönitz died 19 May 1943 as a watch officer on board of U-954. Klaus Dönitz died when S-141 was sunk on 13 May 1944. It was his 24th birthday. After the death of Peter Klaus was permitted to withdraw from combat duties. He started his education as a naval doctor. Him taking part in the attack was sort of a birthday present from his comerads, whom he conviced to take him along.

[@hrafnofthule5962]

Fanatic Productions what does S stand for in S-141?

[@johannesr4503]

Hrafn of Thule i think it stands for „Schnellboot“, which is the german word for speedboat. They were small boats mainly used for torpedoing coast shipping, but also for things like laying out mines. (So they basically were torpedo boats)

[@RGA1944]

Later in the war, Allied ASW was so advanced that approaching the convoy to close distance was very dangerous if not suicidal. As the result, the Germans started developing pattern-running torpedo (called FaT, Flächenabsuchender Torpedo) which would run straight for a predetermined distance, then start zig-zagging along the convoy's course with hope of hitting something on the way.

[@conejoibuxai1510]

To their own shore, Came the world war. Gleaves and Ingham, Leading the bury west. In their own track, Came the wolfpack. Gleaves led the convoy, Into the hornets nest. At the crack of dawn the second day, Bury stands in flames. Half the convoy sunk or disabled, Heading back to the shore. But below the north Atlantic, On the bottom of the sea. On the second night in the darkest hour, The kriegsmarine return. The wolfpack surface for a second time. To make the convoy face it's fate. To their own shore, Came the world war. Gleaves and the Ingham, Leading the bury west. In their own track, Came the wolfpack. Gleaves led the convoy, Into the hornets nest.

[@nopan362236]

Everyone talks about the German submarine campaigns in WWI and WWII that ultimately failed. But little attention is given to the American submarine campaign in the Pacific that succeeded. American submarines virtually destroyed the Japanese merchant fleet and might have won the war even if the other battles had not gone as well for the American navy. This would make an interesting topic.

[@MilitaryHistoryVisualized]

Cause the Japanese ASW sucked. There was no back and forth.

[@phoenixjz4782]

This. Japanese understanding and doctrine of Submarine warfare was pretty much purely focused on warships, with little consideration given to merchant ships. Thus, they rarely attacked Allied shipping, and likewise they also totally neglected the task of protecting their own shipping. What American submariners had to face as an adversary in their war was nothing like what Axis submarines had to face in the Atlantic & Mediterranean.

[@malsypright]

Why wouldn't they protect their transports and convoys? That seems pretty stupid...

[@lovablesnowman]

@@MilitaryHistoryVisualized you have Clay Blairs book down in the sources but you seem to still propagate some myths regarding the battle of the atlantic. As Blair points out and argues very successfully the uboats never posed a serious threat to allied shipping at all. 99% of allied shipping reached its intended destination. And when the allies actually bothered to try and make an effort against the u boats they utterly and totally defeated them with the Kriegsmarina suffering arguably the largest defeat of any arm of the axis powers the entire war being totally and utterly obliterated. Just curious whether you don't agree with his conclusions or whether you just chose not to mention it for whatever reason.

[@binaway]

True. It was the only truly successful submarine campaign. British and Dutch submarines operating from the Australian city of Perth had success in the Indian ocean but on a small scale compared to the USN blockade of the Japanese home Islands. British submarines played their a part in the blockade of Germany in both wars. Not in the number of ships they sank but their part preventing them for leaving port. In the Meditation they sent a lot of Axis supplies to the bottom. In the end Germany was a land power and could not be defeated by a submarine campaign whereas Britain could.

I've read the 'Commander's Handbook' in its entirety and I was struck by how unaware B.d.U was of Allied technological advances. Considering it was written in 1942-43. For example the Handbook only mentions the asdic but by then the Allies had true centimetric radar, and mounted on planes at that. And they're still advising their captains to find the proper deep layers between cold and warmer water where asdic was known to lose accuracy. Ach, those poor U-boat crews of 1944-45!

[@samstewart4807]

As usual an excellent video. Here is my question. Why did the wolf packs never take out the escorts? If the escorts are first attacked by 6? uboats - then there is no opposition to sink the convoy .

[@MilitaryHistoryVisualized]

thank you, because escorts are more likely to change course, are more likely to notice if a torpedo passes by, are smaller, are faster, are far less, thus less likely to be a target of opportunity, are also very cheap, etc. So, there is every little incentive to destroy escorts, especially early on, when they were rather weak and later on, they were too many.

[@skyden24195]

The 1943 film, "Action in the North Atlantic," created as a morale-boosting propaganda film, depicts a focused look on the lives, duties, and tactics of a group of U.S. Merchant Marines during WWII. The film was praised for its accurate depiction and promotion of the Allied Merchant Marine forces, even to the point that the movie was included as a training film by the U.S. Merchant Marine Academy, as well as inspired the U.S. Merchant Marines to gift a victory flag to the films' creation-studio (Warner Bros.) president Jack Warner. During the course of the film, there is a depiction of a "wolf-pack" attack on an Allied convoy. These scenes are quite intense, and the film itself is definitely a highly recommended watch for anybody with an appreciation for WWII's Battle of the Atlantic.

[@williamgassmann3836]

I respect this mans so much

[@xenosienack2386]

Nice that you also mention the reconaissance units from the luftwaffe that worked with the uboats to search for convoys. A more Well known unit may be the fernaufklärungsgruppe 5, they where mostly equipped with the 4- engined JU-290 and had there base in Mont de Marsan. However these units where not that succesful, barely any convoy attacks where conducted with the information from the gruppe. Maybe the topic is intresting enough to make a video about it.

[@alang6402]

The drawback of having WP attacks co-ordinated from a land-based station is that the signal traffic could be detected. Even when the messages could not be decoded it was possible to determine when WP was forming up for an attack because of traffic analysis and RDF. Even with the change to 4 rotor Enigma machine, that stopped Bletchley Park from reading the messages, the already accumulated experience of U-Boat practice together with the growing body of messages meant that the weather codebooks could be reconstructed and the days Enigma settings could be found. It is a case where success for the U-Boats means more signal traffic that in turn makes it possible to read the signals - a case of success breeding failure. Of course, often knowing an attack was forming up could not prevent ships being sunk but it could help to redirect the convoy in some cases and alert the escort to the impending attack.

[@wolf310ii]

The HQ send twice a day to fixed times orders and messages to the U-Boats, so the signal traffic is there, with or without a WP attack. The HQ plan not every detail of an attack, its more like: course and position of a convoi and a attack time, move your ass and do your job

[@thomas.02]

Would you do a video on intelligence services, particularly Axis/German intelligence? The rationale is because the Allied intelligence services are much talked about but it seems that their Axis counterparts are rarely mentioned, at least to laypeople like me.

[@axelpatrickb.pingol3228]

Their intelligence arm, the Abwehr was primarily shit. Mostly because of the inherent weakness of the Prussian/German military doctrine that place less stress on intelligence. Their greatest blunders include not having Free Ireland join them because the agents responsible for that did it poorly and Operation Barbarossa which as done mostly with false and inaccurate information.

[@hugh5006]

Nazi intelligence was embarrassingly shit during the war. Let's just leave it at that.

[@visionist7]

They had many coups which today are forgotten. They tapped the super secret transatlantic telephone line and listened in on The Fat Controller and Wheelchair Dude's chit chats. They also found and sank an enemy ship or thousand on the high seas by working out their position via radio intelligence. Google the Venlo incident.

[@AjitMD]

The Nazis were stupid… low intelligence. They persecuted Jews and others who were very educated… because of religion, etc. Einstein, Oppenheimer, etc. Did not realize that codes are usually broken. No communication is safe. If they had any common sense - let alone real intelligence - they would not have invaded USSR which had a massive military, superior tanks, limitless manpower , energy, resources.

[@mebeasensei]

The later tactics borrowed heavily from the German Wolfpack. The Japanese had been more concerned about protecting warships instead of merchantmen. They got a very rude awakening once the USN got a decent torpedo--which wasn't until 1944!

[@nittanyburg20]

Manning a submarine that’s being hunted would be terrifying

[@julianmhall]

Granted navigation was an issue, but at least if a convoy was spotted the UBoats would have a radius to search inside given that the convoy could only move at the speed of the slowest ship. That would concentrate the search into 1,256sq mi (if the speed was 20mph and it took the UBoats an hour to get there) instead of several million - a much smaller haystack. If the course was /also/ known then the convoy would be within 20 miles on that course, hardly difficult to locate. Also they'd be unlikely to reverse course so it would be more like 633 sq mi at worst

[@leary4]

I think the more interesting topic would be the tactics adopted to counter the "wolf packs". In a nutshell it was simply a matter of concentrating resources. Divide the north atlantic into grids. Instead of attempting to protect convoys and cover several grids over x periods of time. Attn. was concentrated on a single grid for x+ ten (or the number of days it took until subs moved to another grid). In this scenario thx to long range aircraft a sighting would typically mean a kill. Even this was after the English Navy by sheer balls and seamanship bested the "super killers" of the U boat fleet. U can divide u boat captains pretty much into two categories; super killers, numbering about 5 and others. The tonnage sunk by a very small number really was remarkable. If they could be taken off the table Britain could maintain ,however tenuously, it's Atlantic lifeline.

[@merafirewing6591]

Imagine if an American V-boat clashed against a German U-boat.

[@ramal5708]

No one ever mentioned that the US also utilized Wolfpack like tactics against Japanese convoys in Pacific WWII. They were also successful until their US Torpedoes failed them at the last moments, classic

[@thetruthcompany5635]

As early as the summer of 1939, Dönitz sent a memorandum to both the naval command and Hitler personally in which he demanded 300 boats with which he (rightly) believed GB could be brought to its knees and forced to negotiate peace by cutting off its supply of food and war materials from overseas (by 1941, the Reich government had received more than 20 peace offers through neutral intermediaries such as the Papal Nuncio, the King of Spain, the King of Sweden, the Swedish merchant Birger Dahlerus, the famous Swedish naturalist Sven Hedin, the government of Switzerland, but also directly to the British Ambassador to Spain Samuel Hoare and even through his personal lawyer Dr. Weißauer, all of which were rejected despite the (earnest) offer to withdraw from all occupied territories in Europe and even to vouch for the protection of GB's colonies, he merely demanded "a free hand in the East" against the arch-enemy of Bolshevism.) But Hitler went on 1940 or 1941 needed, not 1943, by then the British destroyers were equipped with ASDIC and radar and the hunters became the hunted! As Ritterkreutz carrier Reinhard Hardeggen correctly said, "Hitler stood with his back to the sea. The war was decided and lost at sea!"

[@lightupdarkness]

[@isaacramirez3634]

Did Russia have a navy in WWII?How did the Purge change it? What made it different from the other naval forces of the time? Was it effective against the Germans?

[@axelpatrickb.pingol3228]

They have, it's pretty much the same as it as during the first World War when it was called the Russian Imperial Navy save for cosmetic changes like names. Their primary warship class is the Gangut class which was from the early days of the Dreadnought hich some were refurbished. One, the Marat was sunk somewhere in the Black Sea and was used primarily as a artillery battery for Crimea; the other ships pretty much were kept in port. The Red Nvy as an organization was instrumental in some of the most ferocious battles in the Eastern Front, the biggest is the Defense of Sevastopol.

[@BarManFesteiro]

watching this video after dying on my third patrol in SH5 (may of 1942 artic) because i attacked a massive english task force. I did manege to sink a british heavy cruiser for 13000t and another ship for 4000t but was depth charged by multiple escorts for hours before getting one to the bow and dying. I feel like no captain would attack a convoy or task force so heavily defended like that on their own. Any thoughts? im just wondering what kind of tactics could have been used. Right now im shadowing a huge convoy but with little hope of actually engaging anything, at least four destroyer escorts and no support so i think ill pass that one.

[@johnkirke8356]

From 1942 to the end of the war the U boats had become the hunted..75% of deployed boats were lost, and 66% of those had no survivors.. 33% were ó their first patrol..from Sep 42 to May 45 some 43500 merchant vessels crossed in the Atlantic convoys.. of the U boats sank approx 270. 99.4% of shipping on the North Atlantic convoys reaches destination. U boat concept never came anywhere near interrupting supply between USA and UK.. it was an ill conceived idea and maybe had Donitz been more pragmatic and less attached to the Fuhrer the tragic waste of lives on all sides might have been avoided.

[@wolf310ii]

Your numbers are wrong, alone in september, october and november '42 U-Boats sank 329 ships. Even if you mean Sep 43 to May 45, it was still 379 ships. Also the war started '39 and not '43 and until '42 U-boats were very good in sinking more ships than the UK could replace. Even without sinking all ships, every sunken ship that coulndt be replaced caused less ships being able to transport supplys, wich becomes a huge problem for an island wich has to import almost everything. The UK didnt start the war with HF/DF, Ultra, cm radar, ect., it was the opposite, they even thought u-boats wouldnt play a role anymore and even allowed Germany to build a u-boat fleet as large as their own. Saying the u-boat concept was an ill conveived idea, looking from today at the war at '43, only shows how ignorant you are

[@MrArtbv]

I notice you didn't mention the problems the Kriegsmarine had with their torpedoes at the onset of the war. As I recall there were problems with weak pistol detonators and depth settings. However UNLIKE the American torpedo problems (of which whole books have been written and even a movie made): Doenitz actually listened to his commanders and by mid 1940 the problems were resolved. I think the depth settings were due to salinity differentials between the Baltic, where the trials were conducted, and the Atlantic. Another in a long line of great presentations.

[@wolf310ii]

AFAIK it was the pressure differences inside of a u-boat, why the depht setting lost theyr calibration. The problem with the pistol detonators was when the angel of impact was to small, the pistol bend and jam. The problem with the magnetic detonator was, the magnetic field of the earth is not everywhere the same

We can not understand the past unless we learn the lessons from the future.

[@timdesk5035]

Neil Wilson i think that suppose to be the other way around

Because we're filthy free-loading peasants, Tim. The Patrons are worth exactly four days more than us.

Do you know of any instances of u-boats timing their attacks so that torpedoes impact at same time? In the movie Greyhound, they show two u-boats making a coordinated on the Greyhound Fletcher Class Destroyer. Do you think is realistic or know of any similar occurrences. It seems that it would be very hard to time torpedo strikes with 40's technology.

[@wolf310ii]

No, thats pure fiction, u-boats didnt coordinate their attacks, especialty not on escorts. Escorts were very low priority targets.

[@reinoldi1097]

Otto Kretschmar :P read the book xD genius ^^

[@knighttemplar6529]

Why didn't the sub commanders target the Escorts so the Merchant men were more vulnerable and they wouldn't have to worry about depth charges

Never bring a baguette to a sword fight.

[@LukeBunyip]

free_at_last During the 90's, a group of Australian Aboriginal artists were invited on a cultural exchange to France. Upon their return, they were asked what they thought of Paris. One of them, that had spent his entire life living in the desert of Central Australia said that he thought the French were nice, but he didn't understand why they carried nulla nulla (fighting sticks, or clubs) everywhere. One of the other artists had to explain to the white journalists that were interviewing them that he was making a joke, and was actually referring to baguettes.

Is that a broken "baguette" shown for the Fall of France in 1940 ? ;)

[@visionist7]

I wanna garlic baguette

Here’s a thought 🤔 from the combined ship cost in resources to build and crew “Bismarck , Graf Spee and Tirpitz “ how many more U-Boats could’ve been built and crewed. Just a thought since the U-Boats were more successful.

[@callsigncowboy4507]

You’ve sounded a little sick the past few videos, you doing alright?

[@MilitaryHistoryVisualized]

there are/were some issues, yes.

[@lucariolu4875]

Wuff Wuff!

[@Christopher-N]

It is very briefly mentioned in this video that one attack tactic was to get within the convoy to attack the merchant vessels. This U-boat tactic spreads confusion in the convoy, but also makes it difficult for an escort to counter-attack the U-boat. I feel this does not get the attention it deserves in this video.

I like the accent- sounds like a secret special agent...

He’s Austrian.
