The Hunt For The Legendary U-Boat Ace | Last Secrets Of The 3rd Reich | War Stories

this channel is part of the history hit Network stick around to find out more [Music] a ghostly Hulk on a Sandy grave of the South American Coast yet this crumbling tomb was once a pride of the Nazi Fleet a deadly weapon of war that sent scores of sailors and ships to the bottom they were in fact in one of the best submarines in the German Navy she's armed with 15 Torpedoes as well as a deck gun and she is absolutely deadly weapon of war in command a legendary U-Boat Ace respected and admired on both sides guggenberger was an excellent Kanani officer and leader of men he was in the finest tradition of the German submarine commanders but the tide turned and the wolf packs were ruthlessly hunted down they call for battle station so all the guns were made every bomb can be a hit if someone says they weren't afraid they're lying the u513 vanished but the u995 is a rare Survivor more than 600 of her type were Unleashed to prowl the Seas she's the only one left should in 1945 she now rests on a beach below a memorial to the thousands of German Sailors who didn't come back it's interesting how the The Legend of the the German gray wolves endures to this day um it's particularly interesting that people in the in the US and Britain seem to be more fascinated by German submariners than they are with the exploits of their own and I think we can only put it down really to um the fascination with with the underdog with the defeated enemy with a lost cause Brazilian sailor and entrepreneur Wilfredo Sherman is one of those captivated by the legend when he heard the Intriguing tale of a U-Boat sunk off the coast of his native Brazil he had to find it a um the U-Boat has an incredibly engaging history it enthralled me immediately it was as if I was being pulled into this search of course not least because of my family my father is German I'm desperate to find out what this U-Boat meant for the war the Brazilian businessman was chasing a ghost a legend that vanished under the waves in 1943 a lone wolf the u-513 you will never find a thing give up your dreaming I said no we will find it he wandered back through time to the desperate early days of the war when the so-called wolf packs ruled the waves German U-boats tore into Atlantic convoys vital supplies needed to keep Britain and to allies afloat were sent into the abyss along with many thousands of merchants there's no doubt that early in the war the Germans could have knocked Britain out using U-verse even the mightiest warships in the sheltered British Naval Base of scapa flow weren't safe after a gray wolf crept in thank you probably one of the greatest successes scored by the U-Boat arm was going to Prince penetration of scappa flow in 1939 this was striking at the Royal Navy right in its lair in its prime base and the propaganda's success of this was extraordinary it was a navigational Masterpiece and on top of that there were barriers in front of the entrance in this relatively small space strong currents were also prevalent now foreign an American journalist described Kunta Preen as clean cut and cocky he was also persistent he fired three Torpedoes at the battleship Royal

launched another attack thank you [Music] British power was symbolized by its Fleet by its sea power and here are young representatives of the Third Reich proving that the old British Empire hasn't got the strength Royal Oak Was An Old Ship she hadn't been modernized but to sink her in Britain's base the base of what was still seen as the greatest Royal Navy in the world or the greatest Navy in the world was an extraordinary success foreign became a celebrity paraded before the propaganda cameras the Nazi propaganda machine went into overdrive after pre and success so he was interviewed by Hitler he was filmed he was awarded the knights cross he was made into a young hero of the Third Reich Hitler was delighted plans to conquer Europe and the Soviet Union would be much easier with Britain out of the war U-boats could cut supply lines and starve the island nation into submission the commander of the German submarines argued this that if he had enough submarines he could sink 600 000 tons of shipping per month and this would knock Britain out of the war the Nazi Creeks Marina started with a fleet of 57 submarines more than 1100 U-boats would be launched into battle but as well as boats the German Navy needed Sailors to mount them a lot of young men would have looked at the U-Boat arm and seen them as a glamorous successful that the spear point of the German Navy when the rest of the fleet was spending an awful lot of time in Port also we must remember that young men everywhere always think of themselves as invincible horse breeder was just 17 when he enlisted desperately wanted to join the U-Boat units when I joined the Navy you were really put through the mill I checked you thoroughly you had to prove yourself on Board of Health recruits were sworn in with the Admiral dernitz Mantra attack approach sink it this was an elite which you would want to connect yourself with and it's a sign I think of the success of the propaganda machine The Cult of the U-Boat Aces that it was so attractive for people to volunteer for what turned out perhaps to be a rather nasty brutish and short experience of operating submarines but life at Sea wasn't always the worst option you could sit in a foxhole in the Russian front you could perhaps train up as an ill-trained night fighter pilot or you could go to see in submarines where the risks on patrol were extraordinary but when you came back you were in France in relative safety in a barracks in relative comfort Sailors eager for adventure could travel across the globe in a new generation of long-distance U-boats [Music] the u513 was one of them new 513 was a formidable weapon she is a type 9C U-Boat these are long-range U-boats designed for distant ocean patrolling sometimes they're called U Cruisers so their endurance was something like 13 and a half thousand miles instead of about eight and a half for a standard type 7c boat she's armed with 15 Torpedoes as well as a deck gun and she is an absolutely deadly weapon of War her crew claimed four kills in a month but then suffered a series of breakdowns in mechanics and morale the commander was replaced by one of the most dynamic officers in the fleet 28 year old who was already a legend guggenberger is an interesting character um he's often portrayed as a Maverick U-Boat commander and in fact Admiral dernis used to reprimand him for the length of his hair but he was successful he knew how to get results by reputation he handled his submarine in a very aggressive kind of way um he was in the finest tradition of the German submarine commanders in that sense he'd already sent at least a dozen ships to the bottom including one stunning kill that sunk a prize of Britain's royal Navy gogenberger's moment in the sun before this and at the moment where he really becomes a U-Boat Ace is when he Torpedoes the British aircraft carrier hmsr Royal the Germans have been going after art Royal since the start of the war and have repeatedly claimed to have sunk her but guggenberger is the man who actually gets her foreign British Naval Pride as far as that was a real success because it created a hole and in those days you didn't have this serial manufacturer of aircraft carriers so every one of them was a serious loss for the enemy guggenberger became another fated U-Boat Ace a hero of Nazi Germany foreign [Music] was a very important ship to both sides so it was natural that guggenberger as the man who sank her should be given the highest possible gallantry Award with the maximum level of publicity the British was sad that our cruel had finally been sunk the Germans were overjoyed he was awarded one of the highest honors by the fuhrer himself the knights cross with oak leaves in May 1943 he had a new boat and a new mission loaded with Torpedoes enough food for 16 weeks and tropical uniforms they were Bound for exotic Dangerous Waters [Music] the deadly consequences of Japan's surprise attack on Pearl Harbor in December 1941 had spread far beyond the Pacific Hitler declared war on America three days later her vast industrial and Military might brought the wolf packs to heal once the U.S is in the war the Western Hemisphere basically becomes just as dangerous as the Mid-Atlantic and the East for U-boats the entire might of the U.S Navy the U.S Coast Guard plus their allies eventually like the Brazilians becomes ranged against the German submarines America could build Merchant ships faster than the Germans could sink them [Music] as well as tanks and planes factories churned out a stream of so-called Liberty ships the key to the mass production of birch chips was to come up with a simple common design which could be welded together quite rapidly the tonnage lost could be replaced and indeed the size of the Allied Merchant Fleet increased no matter how many ships the U-Boat sunk there were two or three more to take their place but fear of the gray wolves remained and for good reason [Music] long-range U-boats were still prowling far and wide in September 1942 The Troop ship Laconia set sail from Cape Town for Liverpool civilians on board included 14 year old Josephine Pratchett and her family at that time the Atlantic Neil boat was at its height there were huge tremendous successes for the U-boats the ship was very slow belching out black smoke the whole time and we knew we had to go through in the Atlantic where they all were unfortunately for the Laconia the u-156 was lurking off the West African Coast the passenger ship Laconia was armed and operating as a troop ship so she was absolutely a valid Target [Music] Lieutenant Commander Berna hartenstein seized the opportunity to send another allied ship to the bottom it was horrendous the ship lurched very badly the explosion was Extremely Loud and then there was a kind of incredulity really you know a hush before the next torpedo struck many survivors were floundering in the water including Italian prisoners Lieutenant Commander Verna hartenstein's allies then he realized there were Italians on board there were prisoners on board and his conscience was now stronger than any rules of War at Great risk to himself and his men hartenstein surfaced and called other U-boats to help on the capital came onto the deck and with a megaphone he said in perfect English I would like all the women and children to come aboard my ship can you imagine the enemy saying that we must also remember that what motivated him was the fact that he heard the voices of Italian prisons of war in the water his allies whether he would have gone to the rescue of Allied survivors alone who knows but there's no doubt he did try and help everybody who was in the water times of War when you think what could have happened so you expect you could be rescued by your own side but you don't expect to be rescued by the other side do you really but we were and not only that but we were treated extremely well and I've lived to tell the tale some survivors were taken on board the U-boats others were towed in lifeboats behind them laughs that's why I was one of the most elaborate rescue operations of the war I think of the whole Casino [Music] the lifeboats were being towed by the submarines and he tried very hard to save as many survivors as possible making himself extremely vulnerable hackenstein made an open radio call in English assuring any ships that helped would not be attacked it attracted deadly attention it was an enemy submarine he has a chance to sink it try and sink it shoot first and ask questions afterwards it's a ruthless decision but they've got a chance to get a U-Boat on the surface at a point where the U-Boat war is the single biggest threat that the Allies are facing he said it's too dangerous I can't keep you on board anymore survivors were cut loose many were rescued by friendships the u-156 escaped and received a Stern general order from headquarters one of the interesting consequences of the harpenstein incident is that during its issues the laconian order forbidding new boat commanders from helping survivors in reality it doesn't make any difference conditions for U-Boat commanders are getting very very difficult at this point and it's not long before no Commander can afford the luxury of of indulging in this kind of behavior regardless of whether they get the opportunity or not [Music] like her sister boat involved in the Laconia incident the u-513 was a long-range weapon she left her French base in L'Oreal on the 18th of May 1943. her Skipper Friedrich guckenberger could have picked a safer option as an instructor the German Navy would try to use the expertise of somebody like guggenberger and so there was good reason to use people like him in the training mode but of course these submarine commanders are aggressive it's in their bones and therefore he wanted to be sent out on patrol again for most of her crew it was the fourth assignment at sea torpedo mechanic Gunter Blazer was just a teenager obliged to serve his fuel I was 14 and my husband was 17 at the time and our childhood romance grew but then he had to become a soldier before he even turned 18. [Music] his engineering skills were in demand most young men who left on a U-Boat never came back but margarita would wait for her sweetheart I knew he was the one when I was 13. foreign it was a journey into the unknown for operational security reasons U-Boat Crews weren't told where they were going until they'd left Harbor obviously what you don't want is the boys out for a night on the town in the bars of L'Oreal spouting to the locals about where they're going the next day Walter vittig was a radio operator on a sister ship of u513 of course you would think what was ahead when you left on assignment where are we going if someone says they weren't afraid they're lying once out at Sea the orders finally came through the u-513 faced a long Voyage far beyond the relative safety of her home base on the French Coast [Music] she set a course for the other side of the Atlantic for the waters south of Rio De Janeiro it was a rich hunting ground for freighters carrying a vital raw material for the Allied war effort Brazil is essentially the only large-scale source of rubber remaining to the Allies the Germans Allied the Japanese has captured nearly all the other major rubber producing areas in Tunisia Malaya and so on so Brazilian rubber becomes this vital resource for the Allied war effort and the Germans know this it's a long long way away but they're still able to dispatch these long-range type 9 U-boats [Music] on the long uneventful Voyage the commander had to ensure his crew were ship shape it gave them the best possible chance of making it back home to their loved ones [Music] it's well aware that he's got a perhaps a less than 100 efficient Crew He drills them and trains them relentlessly as they cross the Atlantic God the big tight nine Seas these were very large U-boats and they were known as slow divers at made sure that he ran as we say in English a tight ship that the training of every member of the crew was absolutely vital to the efficiency of the submarine and that to a very considerable extent the crew would have to be driven to make sure that they were operating at maximum efficiency when you have them it's my new evil [Music] someone 30 seconds and with an acknowledged async command I suspect that the men although they might Grumble about it probably felt confident in the end that they were in fact in one of the best submarines in the German Navy in fact their bow to change for being one of the worst to being one of the most potentially effective submarines in The Creeks Marina in a real Attack a U-Boat on the surface was a Sitting Duck the commander presses the alarm signal and that means an emergency dive nobody knows if this is an exercise or the real thing it took 35 seconds for a type 9C to crash dive and get underwater and it was absolutely essential that they shaved every second that they could after that time I know foreign that's in the afternoon new boats had to maintain a constant watch Smoke on the horizon meant a possible Target or an attacker closing in but a long Voyage to Brazil was mostly uneventful hot stinking and claustrophobic we always said that the engineers designed a fantastic boat with fantastic technology but when they finished they realized dear God people have to go in there too a chance to escape the cramped confines came when the Horizon was clear and the water calm the Open Sea a welcome reprieve from a steamy interior on a tropical voyage it was a mixture of sweat torpedo fumes chlorine fumes from the battery also the smell of the galley now imagine all this together in one room eventually you no longer perceive it but the circumstances under which the crew had to live in the U-boats are hard to imagine um foreign apart from the occasional rendezvous with Supply vessels including modified U-boats dubbed milk cows Crews were on their own [Music] their lives depended on the sea worthiness of their boat and there was a vast array of Machinery to maintain the all-important batteries needed constant topping up with fresh water u-513 chief engineer Gunther zeidel was fanatical about preserving water one of the major problems submarines face right from the start was their very limited capacity to carry fresh water and this had effects on submariner's way of life washing and operating conventional submarines don't go together even today in fact conservation of water is very important but when the miserly zidle band coffee the commander stepped in gergenberger was an excellent commanding officer and leader of men but he also has an absolutely finely nuanced eye for reading his men's moods [Music] a good example of that is the story of his chief engineer Banning coffee to preserve water and one has some sympathy for him mortar's a vital resource but guggenberger reads the mood and goes no the men are having their coffee and immediately gets them on side foreign ER was an important thing on board of course there was a difference between superiors and subordinates but not in the same way as it was on a big ship or on land that didn't exist on a U-boat it was a tight-knit community crammed together in a small steel tube thousands of miles from home events like birthdays broke the monotony of endless days at Sea it's not possible to teach someone who's been blind from birth about color and if you haven't lived through it this state of being completely reliant on each other absolutely it's difficult to understand what this companionship actually meant uh the Mr smear classes submariners could spend weeks at sea without seeing another boat [Music] yet their orders were clear sink ships you travel back and forth hoping you will come across someone anyone he was up for book life after two months at sea oh my God [Music] the lookout spotted a Target on the 21st of June sinking a enemy ship with a torpedo from a submarine is a really tricky business scientific mathematical game what the commanding officer has to do is look at his Target and he has to judge where it's going to be when his torpedo reaches it so he's looking at the speed and course of the target speed and direction of travel of his torpedo and if he gets it right they'll meet on the cross what a submarine Captain can't do is stay on the surface with his Periscope and look at what's happening it's far too dangerous so what he does is he will fire his torpedo do his calculations via his torpedo and then the eels go off and we sit and wait eyes on the stopwatch to see how much longer they should travel and wait for the bank stopwatch is his running time for that torpedo when it reaches say 50 seconds or two minutes or four minutes he should hear the [Music] the Swedish freighter Venezia was sunk the crew saved themselves but this wasn't always the case the crew was elated it's understandable this was their job for most U-Boat Crews such Elation was short-lived Allied ships and planes work together to protect convoys and to hunt and destroy boats like the u-513 by 43 you are facing a mature anti-submarine system there are some ships are in Convoy other ships are not but the Americans have developed a very effective hunter killer system for dealing with submarines and there's good burger found off the Brazilian Coast in the summer of 1943. it was almost as bad as being in Mid-Atlantic bad weather was no cover the hunter Killers could still find a U-Boat in a storm the most important thing was to get as deep as possible as fast as possible [Music] on the surface a U-Boat is just a very thin-skinned slow and very vulnerable little boat foreign [Music] submarine is vital if you're not going to be found out ping is active sonar passive sonar is a guy with headphones and effectively ears on the side of his ship and they can hear the slightest noise you can only be really quiet don't run about all machines are off but other than that you can do virtually nothing oh my gosh that's the guy who would hear you drop your pen on the deck once you've done that the searching warship knows that there's a submarine there you go then they can start pinging with their active sonar [Applause] that's when they learn to pray and find you and find how deep you are and find how far away you are and then you're essentially dead foreign [Applause] [Music] what's important is that the bombs explode above the boat and not below the boat if they explode below it's usually all over foreign you can't really describe it once we had a situation where it went on from eight in the morning until 10 at night and then you have three ships up there and they cross over and take turns discharging bombs the stress of being repeatedly depth charged and hunted down for hours and hours and hours at a time is again almost inconceivable for us today that the psychological reflexes to fight or flee and the Submariner can't do that he's just to sit there and take it that's when you try not to think about anything American planes sunk at least 16 new boats in the South Atlantic in 1943 and 44. [Music] at the beginning of July 1943 the u-513 had survived to kill another day [Music] once a Target was spotted the crew tried to identify it using a shipping register all right [Music] the u513 scored five impressive kills off the Brazilian Coast including two american-built Liberty freighters [Music] enberger manages to sink five ships off the coast of Brazil in summer of 1943. this is not a good time for U-boats the U-Boat campaign is on the way here the U-Boat arm is being defeated and it speaks volumes for his qualities as a commanding opposite he manages to achieve that kind of success rate in a very difficult period for submarine Commanders foreign [Music] [Music] moment of carelessness by the veteran U-Boat Ace [Music] the u513 sent a radio report back to headquarters but at the start of the war that was normal but other than that we hardly ever sent Long Radio messages I only ever sent a single message from the Brazilian Coastline and that was a signal with seven letters even a short message could reveal a U-boats position you need two receivers both of which will intercept the same Wireless transmission what you get then is a cross bearing and if you run down the bearings where they cross that's exactly where the U-Boat is and then you can dispatch escort forces and hunter killer groups to go find the submarine and sink it basically what he was saying in code was here I am come and kill me American Mariner seaplanes were a lethal threat able to zero in on any U-Boat caught on the surface the Americans had a very effective radio Direction finding system for as we say queuing flying boats to go out and search in areas this is a great big lumbering flowing boat bristling with Weaponry capable of flying thousands of miles out across the ocean and back again and when this aircraft encounters u513 on the surface the odds are heavily in favor of the pilot I decided to turn on the radar and flipped it on and started watching it a while and then I saw this very peculiar blip which was very sharp and very distinct I thought it was a fishing boat at first it was a little curve to it but it was so bright it just just jumped out at you it didn't seem quite right for a wooden vessel one of the Bombardier he got binoculars and he said it's a submarine and then Roy Roy started working his way into the clouds so that he would be better concealed goodenburger was cool napping by the Mariner Patrol aircraft there are several options he could have done he could have immediately ordered his crew below and crash dived as soon as possible [Music] but it's still going to take 35 seconds which would have seemed agonizingly long basically he's lost the battle really when that aircraft catches him unawares they call for battle station so all the guns are a man according to One account the deck gun jammed but whatever Firepower was available it was no match for the Mariner the greatest Terror for any U-Boat commander in 1943 is to be caught on the surface by an aircraft an aircraft is an almost guaranteed U-Boat killer and certainly what submarines don't have is a chance of fighting out a battle against an airplane the Mariner dropped depth charges around the u-513 killer blow exploded just below the boat torpedo mechanic Gunter bliser was one of the lucky few saved by a shipmate [Music] he'd seen the aircraft and called down Gunther come up here we'll never know if it was intuition if that hadn't happened he would have sunk with the rest of them for most of those on board the boat became their tomb 66 years later the search for the u-513 started with the former American Airman who played a key role in sinking determined to find the enigmatic wreck of his native Brazil businessman Wilfredo Sherman was hunting for Clues the u513 kill dorbed on the plane that sent her to the bottom a former Airman had the approximate coordinates of where his crew had sunk her I don't really know you could cake in there they get the position that the Navy thinks it was and you can figure that out how far offshore we were the coordinates were not precise [Music] Texas the quest to find the u-513 continued from the Brazilian port of Florianopolis south of Rio provided more clues the locations of mysterious obstacles on the sea floor that tore their Nets it's cold but inside I'm feeling hot with excitement and other intriguing Voyage began to the scene of a fateful battle a hundred kilometers offshore crew deployed a side scan the sonar a radar device they hoped would reveal the Lost wreck but after 17 trips and days of searching enigmatic U-Boat eluded them until a strange signal emerged some 75 meters below the boat [Applause] [Music] an elated crew were sure they'd found the u-513 but the object was too deep for divers to investigate a remote controlled camera was sent down to illuminate what lay in the Eerie Darkness below divers checked that the video link to the ship was working before the camera was directed to the sea floor completely there were anxious moments as another apparently featureless Sandy Vista stretched before them until a ghostly shape emerged in the Gloom almost 70 years after she vanished the gray wolf u513 was found [Applause] [Music] a wreck and also a grave for 46 sailors [Music] a torn Hull evidence of the depth charge blast that sent them to their Doom [Music] foreign [Music] but a lucky few escaped in the critical seconds before she sank after the attack there were about five or six men in the water so we Circle low and drop two life rafts among the survivors the captain and legendary U-Boat Ace Friedrich guckenberger gutenberger obviously chooses not to go down with his ship to be honest this whole issue of a captain going down with his his ship is sentimental rubbish a captain's Duty on either side is to get back get back in the war and bring back the lessons that he's learned from the battle that he's taken part in and you'll find that on both sides during the second world war most commanding officers will try and keep themselves and their men alive even when scrambling for their lives crewmen continued to respect their Skipper taking off his clothes in the water and was only wearing his thick jumper and then he asked his captain captain May our request to enter the boat I'm only wearing a jumper he didn't really want to get in half naked he was always considering etiquette foreign survivors made it onto the life rafts before they were picked up by the American Navy [Music] it would be standard operating procedure to call in a surface ship just to see what had happened and also to pick up survivors after all picking up a U-Boat Captain might yield a certain amount of intelligence for example so there wasn't just humanitarian interest and tried to pick up the crew even though his U-Boat was at the bottom of the South Atlantic capite guggenberger continued the fight in captivity with officers like guggenberger trying to keep them in was often difficult and of course guggenberg is involved in one of the Great Escapes of the uh on the American side [Music] one of the best illustrations of this point that guggenberger's Duty was to to keep in the war is really the fact that even as a prisoner in the United States he escapes from captivity twice a first time heading for Mexico he hasn't really got much of a chance of getting home although Mexico is neutral but what he has got a chance of being is a Monumental pain in the neck to his captors forcing them to deploy troops frightening civilians getting a propaganda success so he's doing everything he can to stay in the fight even as a prisoner in the U.S together with 24 others he staged his own Great Escape tunneling out around Christmas 1944 but in the United States you would stick out like a sore thumb as a somebody who spoke English with a strong accent particularly in a state like Arizona they were recaptured within weeks there was also No Escape for their comrades still fighting a losing war on the high seas three in four U-boats never made it home the survivors of the u-513 were released in 1946 torpedo mechanic Gunter Blaser married his childhood sweetheart Margarita who ensured his compelling tale of service and survival was recorded for this program as for his acclaimed Captain Friedrich guckenberger the exploits and Adventures continued long after the war so the U-Boat Aces is they had a tendency to live fast and die young guckenberger survives the war and his career continues at the end of the war the German Navy is disbanded there is no German Navy so this incredibly intelligent motivated young guy trained as an architect when Germany gets a Navy back in the 1950s he re-enlists he becomes a senior Admiral with a senior position in in NATO and retires you know with the laudits and honors of not just his Nation but his former enemies and then he dies this bizarre mysterious death at home as an elderly man goes for a walk in the forest never comes back and his bodies found two years later in the woods it's all part of the Intriguing story that compelled another sailor to find guggenberger's last command the long-lost wreck of the u-513 really it is an incredible feeling that we found this U-boat we can hardly believe it I'm just ecstatic to be part of its incredible story it's a story of Bravery desperation and sacrifice on both sides the naval Memorial to German war dead including more than 30 thousand submariners survives not to glorify War but to pay tribute to the sailors who made the ultimate sacrifice for their country [Music]
