World War I U-Boat wreck discovered off Scotland

The wreck of what is believed to be UB-65, a World War I German U-Boat lost in 1918, has been uncovered by divers laying an undersea power cable off the coast of Stranraer, Western Scotland.

Dr Innes McCartney, a historian and nautical archaeologist, told the BBC;

The submarine was caught on the surface at night, recharging its batteries. It saw the patrol ship coming. It attempted to do a crash dive to get away. Once the submarine was under water, it rapidly started flooding from above so they had no option but to blow all the compressed air they had, bring the submarine to the surface at which point all they could do was surrender.

The U-Boat then sank again for the last time.

The wreck was discovered by engineers involved in the £1bn Western Link project which involves laying a 239 mile sub-sea power line between Ayrshire and the Wirral that will carry renewable energy produced in Scotland to England and Wales. The engineers found the wreckage 120m north-west of the centre of the planned route. It is hoped further investigation of the wreck will confirm its identity.

Five Of The Most Significant Submarine Attacks In History

SM_U9_Postcard

The development of the submarine changed the very nature of naval warfare forever. Suddenly, the huge fleets of yesteryear found their supremacy threatened by an unseen force and for a long time they were largely defenceless to the new weapon. However, it took a certain type of courage to volunteer for submarine duties especially in the early days when their vessels were often as dangerous to their crews as to the enemy. As a result of this courage submarine commanders and their crews were often exceptionally daring in their efforts to fight the enemy.

Here are five of the most significant submarine attacks in history.


 

  1. The First Ever Submarine Attack in History

Submarine Turtle Eagle 1776Largely thought of as a 20th century invention, primitive submersibles have actually been around since the 17th century. On September 7th 1776 the submarine Turtle designed by American inventor David Bushnell was given over to the American patriot cause for use against the British in the American Revolution. Piloted by Ezra Lee, the submarine approached the British 64-gun warship HMS Eagle and attempted to plant a bomb on it. However, he was unable to secure it to his target’s hull and it fell off the British ship before detonating which saved the Eagle from destruction. Although a failure, Lee’s mission is considered the first submarine attack in history.


 

  1. The Cressy Catastrophe

HMS CresseyUpon the outbreak of World War I, Britain’s Royal Navy had the most powerful surface fleet in the world and the British people were confident that they were safe on their island nation as a result. That confidence was shattered on September 22nd 1914 when German U-Boat U-9 attacked a formation of three Cressy-class heavy cruisers – Aboukir, Cressy and Hogue.

When the first ship, the Aboukir, was hit the crews of the other two cruisers believed that the explosion was caused by an accident onboard and went to assist them. Seizing the opportunity, U-9 attacked the Hogue and sank it. The remaining British ship, Cressy, attacked U-9 before returning to rescuing survivors of the other two ships. U-9 attacked again and sank Cressy. In all 1,450 British sailors were killed in what was at that time an unprecedented victory for a submarine.

  1. The Submarine That Sent A Nation On The Path To War

RMS LusitaniaOn May 7th 1915 the British liner Lusitania was travelling south of Ireland on a route from New York to Liverpool when it was spotted by the German U-Boat, U20, which was taking part in an attempt to blockade Britain’s sea lanes. At the time the US was neutral in the First World War but despite being warned by the Germans that they reserved the right to attack any ship heading for British ports a large number of Americans were aboard believing that the Germans would never target an ocean liner with 2,000 people on it.

They were wrong.

Shortly after 2pm, U20 fired on the ship and in the resulting explosion and sinking, 1,198 people were killed including 128 Americans. The attack outraged the American people who were at that time largely oblivious to the war in Europe and pushed America closer to the Allies before they eventually declared war on Germany in 1917.


 

  1. Submarine vs. Submarine

HMS VenturerContrary to the myth perpetuated by Hollywood movies, submarines sinking other submarines has only happened in exceptionally rare cases. In all but one of these incidents the target submarine was on the surface when it was attacked. The exception occurred on February 9th 1945 when the British submarine, HMS Venturer, detected the German U-Boat U-864 on the surface with engine trouble. The U-Boat was actually on a highly secretive mission to deliver two scientists and several key jet engine components to Japan, Germany’s ally, for use in their own jet fighter program.

Realising he had been spotted by a British submarine the captain of U-864 dived to escape. The captain of Venturer, 25-year old Lieutenant Jimmy Launders, attempted to match the U-Boat’s dive and by estimating the approximate position of the German vessel, fired a spread of six torpedoes in to its vicinity. One of the torpedoes successfully struck the U-Boat destroying it and its precious cargo. It remains the only time in history where one submarine has deliberately sunk another in combat while both were submerged.

  1. The MV Wilhelm Gustloff

MV Wilhelm GustloffFrom the outbreak of World War II Germany’s navy, the Kriegsmarine, exercised a policy of unrestricted U-Boat warfare against the Allies. This in turn dictated a similar policy amongst the Allied navies and the oceans became a brutal killing ground as a result. In January 1945 this policy was about to reach its bloody climax and it would actually be the Germans who would be on the receiving end. The MV Wilhelm Gustloff was a cruise liner requisitioned by the Kriegsmarine for service as a hospital ship when the war broke out. When it became clear the vessel could no longer safely go to sea it was held in port at Gdynia in German-occupied Poland where it was painted in naval grey and used as an accommodation ship for trainee U-Boat crews.

By the start of 1945 the Soviet Red Army was pursuing the retreating German Army across Eastern Europe and so the ship was pressed back in to service to evacuate thousands of German troops, Gestapo officers, officials and civilians who had made a life in occupied Poland. On January 30th 1945, the ship along with another liner, the Hansa, and a torpedo boat made their breakout attempting to reach Germany through the Baltic. Official records show that over 6,000 people were onboard but the actual number was closer to 11,000 as a large number of civilians desperately crammed aboard and in the chaos of the boarding the crew simply gave up counting.

Shortly after leaving port the Hansa had to turn back because of mechanical problems but the Wilhelm Gustloff continued on before it was discovered by the Soviet Navy’s S-13 submarine. The S-13 torpedoed the overloaded vessel which quickly sank taking around 9,500 people with it of which nearly 5,000 were children.

It remains the biggest loss of life at sea in a single incident.

 

Lt Cmdr Basil “Byng” Boulding’s Logbook, December 1941 (No.812 NAS)

One of the best things about undertaking a project such as Defence of the Realm is hearing from the people who were actually there, their friends/comrades and their families. This week I was contacted by David Boulding whose father served with No.812 NAS of the Fleet Air Arm during the first half of the war. The squadron operated off the carrier HMS Ark Royal before the vessel was torpedoed by a U81 on November 13th 1941.

From then on the squadron operated from Gibraltar flying their Fairey Swordfish aircraft primarily on anti-submarine operations to protect the entrance to the Mediterranean. December 1941 was a particularly busy time for the squadron and David’s father was in the thick of it as his logbook shows which David has kindly contributed a picture of.

On December 22nd, a Swordfish from No.812 NAS attacked and sank a U-boat operating under the cover of darkness using radar to detect it. This signalled the turning of the tide in the war against the U-Boats (see Denying Dönitz the Dark ).

Normally, to save space I scale down the images I use on the site but in this instance I have uploaded the original image so this piece of history can be examined in detail.


 

This is a snap of my father, Lt Cmdr Basil “Byng” Boulding’s log book for 812 SQR operating out of North Front not long after the sinking of the Ark Royal (he told me he didn’t get his feet wet and flew off). That month he flew 72 hours 25 minutes. It must have been exhausting! Sadly his first log book went down with the Ark because he was active right from September 1939 in one of the first events of the war.

He made several attacks on submarines including one confirmed hit Dec 16th. You’ll see the note on the 20th December where he flew with Lt Philips and PO Reason.

I found a note about that period at North Front in an article about his TAG (P Reason) on the internet when he or his family were selling his medals (sad that). I have also a photo (above). My father is second left (the small one) and his TAG, Reason extreme right. This was when he was awarded his DSC. This photo is to be found on the Imperial War Museum website.

Submarine Patrol (1943)

U-boats are evil. Submarines are good.

That’s the general impression the Royal Navy wanted to give the public during the war. The fact that Germany’s submarines were called U-boats helped distinguish them in propaganda films such as this even when tactics and operations by both sides differed only little. Nevertheless this is a fascinating – if somewhat scripted – account of RN submarine operations during the war.

Enjoy.

NEWS: First World War U-Boat wreck identified

Despite having been discovered by divers working on behalf of Scottish Power Renewables and its partner Vattenfall in 2012 researchers have only now been able to positively identify a  German World War I U-Boat laying 56 miles off the coast of East Anglia. The wreck is of the Imperial German Navy’s U-31 which set sail for a war patrol from Wilhelmshaven in January 1915 – almost 100 years ago exactly. Contact with the 31 officers and men was lost soon after and it is now believed that the vessel was sunk by a British defensive mine.

Mark Dunkley, marine archaeologist at Historic England, told Sky News;

After being on the seabed for over a century, the submarine appears to be in a remarkable condition with the conning tower present and the bows partially buried. Relatives and descendants of those lost in the U-31 may now take some comfort in knowing the final resting place of the crew and the discovery serves as a poignant reminder of all those lost at sea, on land and in the air during the First World War.

Tough to Sink

S.S. Laurentic before her conversion to armed merchant cruiser in 1939 (u-boat.net)

It has long been the practice in wartime for the British government to requisition civilian vessels for war service. Often these vessels are used in the logistics role supporting the Royal Navy at sea or the British Army and Royal Air Force in foreign lands. The practice has been used as late as the 1982 Falklands War where perhaps most famously the ocean liner Queen Elizabeth II was used to ferry over 3000 troops to the South Atlantic. Using civilian ships in wartime is a precarious business at best. They are seldom designed with the same level of protection a warship is afforded making them very vulnerable and their vital role in supporting the war effort makes them highly prized targets for the enemy.

One such civilian ship taken over for use by the Royal Navy was the Cunard White Star Line passenger ship the Laurentic. Requisitioned by the Admiralty a week before Germany invaded Poland on September 1st 1939 the vessel was put in to dock for conversion to an armed merchant cruiser which was completed in a remarkably short space of time. HMS Laurentic F51 was accepted in to service on October 15th 1939. As part of her conversion she was armed with seven Breech Loading 5.5inch (140mm) Mk I guns and three QF 4inch (102mm) Mk.XVI naval guns. She was also fitted with a quantity of depth charges for use against submarines.

The vessel was, like many of her kind, primarily employed on patrol and escort duties; armed merchant cruisers were effectively the last line of defence with the Royal Navy’s main fleet and aircraft being the first. Her start to the war was relatively uneventful but all that changed on the evening of November 3rd 1940. A little after 2140 hours her commanding officer, Capt E.P. Vivian RN, was informed that the radio room had received a distress call from an unescorted merchantman, the Casanare, stating it had been attacked by a U-Boat. Along with another armed merchant cruiser, HMS Patroclus, Laurentic raced to the scene west of Ireland at a place called Bloody Foreland.

Unknown to Captain Vivian and his men they were about to face off against one of Germany’s greatest U-Boat aces, the brash and skilled Kapitänleutnant Otto Kretschmer (known as “Silent Otto”) and his crew of U-99. Kretschmer’s attack had been a textbook example of U-Boat warfare, catching the Casanare completely by surprise. The torpedo struck just aft of the vessel’s bridge and she began to list heavily enough for the crew to begin abandoning ship. The wireless operator aboard U-99 suddenly found his headset alive with messages between their victim and the two approaching ships all of which were transmitted uncoded and in plain language.

Kretschmer continued to shadow the sinking Casanare while surfaced and it was not long before he detected the two ships coming to its aid. Picking his moment carefully, Kretschmer waited for the Laurentic to come in to his sights and at 2250hrs he unleashed his deadly arsenal on his second unsuspecting victim of the night (this early in the war few ships had radar to detect a surfaced U-Boat at night but by 1945 this kind of operation would have been suicide for a U-Boat commander). Launched from a distance of one and a half kilometres and incredibly while the U-Boat was turning the torpedo struck the Laurentic amidship near the boiler room tearing open a gaping hole in her side. Kretschmer watched the ship expecting it to sink and indeed a number of her crew had leapt overboard in the chaos of the blast but as the smoke dissipated the Laurentic proved that she was not done for yet and remained stubbornly afloat.

Kretschmer made two more attacks on the Laurentic, one at 2320hrs and another at 2330hrs with the range now having decreased to just 250m. The crew of the Laurentic briefly spotted the U-Boat on the surface and began shelling the submarine which quickly slipped away. The Laurentic was now heavily damaged and was riding much lower in the water than it should be convincing Kretschmer that the ship was finally done for and so he turned his U-Boat away to assess his situation.

HMS Patroclus (u-boat.net)

In the meantime, HMS Patroclus had arrived on station and began efforts to rescue the crew of the Laurentic many of whom were abandoning the ship. The Patroclus’ Captain, William Wynter, ordered that two depth charges be launched over the side in an effort to frighten the U-boat away. He couldn’t have known that Kretschmer was still on the surface unseen in the night. Believing he had successfully drove off the U-Boat, Wynter’s crew began to rescue their comrades but Kretschmer had come about and at 0022hrs the Patroclus was hit by a torpedo from U-99 killing an unknown number of men aboard a lifeboat from the Laurentic that was being hauled aboard at the time. Like the Laurentic the Patroclus refused to sink and twenty minutes later at 0044hrs a second torpedo was launched in to the ship. The torpedo malfunctioned and missed its aim point hitting below the foremast. No doubt gritting his teeth Kretschmer fired a third torpedo at 0118 hrs but as he did so the British lookouts spotted the U-Boat and Kretschmer found his vessel taking fire forcing him to flee yet again.

Dumbfounded by his enemy’s refusal to sink, Kretschmer searched for his first target, the Casanare, to confirm it had indeed sunk. Two lifeboats bobbing in the water at her last known position offered the proof he was looking for when suddenly the air around him growled with the sound of aeroengines as an RAF Shorts Sunderland flying boat appeared over the scene. Kretschmer ordered his U-Boat to dive and the RAF aircraft was unable to launch its weapons but remained on station trying to locate the submarine.

Kretschmer used his time submerged wisely and reloaded the torpedo tubes. With the sound of the Sunderland’s engines dissipating he felt confident enough to surface at 0330 hours. Rather arrogantly he went back to the site of his attack on the two armed merchant cruisers and saw that Laurentic and Patroclus had still yet to sink! At 0435hrs he fired a fourth torpedo at Laurentic which struck astern. The blast ignited the depth charges stored in that area resulting in a huge explosion. The Laurentic’s luck ran out and the ship began to sink by the stern disappearing forever.

Kretschmer then turned on the Patroclus but as he did so his own lookouts spotted a destroyer, HMS Hesperus, approaching on the horizon. Rather than be satisfied with sinking the Casanare and the Laurentic he made a hasty attack on the Patroclus. At 0516hrs a fifth torpedo struck the ship fired from U-99 but the British ship refused to go down one last time prompting Kretschmer to fire a sixth torpedo. That was the end of the Patroclus and the hull crumbled into pieces before finally sinking. 114 sailors had been killed in the whole incident.

Kretschmer immediately ordered his U-Boat to dive as the destroyer zeroed in on him. Kretschmer and his men now paid for their victory as they were repeatedly depth charged by the Hesperus but the destroyer failed to score a direct hit and Kretschmer returned to Germany a hero.

So just what was the secret behind the Laurentic and the Patroclus that kept them afloat for so long? Was it excellent damage control techniques? Perhaps it was superb craftsmanship in the construction of the two vessels? Actually it was neither. It was in fact the placing of thousands of empty oil drums inside the hull of the ship. This dramatically increased the overall buoyancy of the vessels which meant that despite several gaping holes in the hull the barrels kept the vessels afloat making them very tough to sink.

The scale of the U-Boat threat on 18th October 1942

This image was sourced from U-Boat.net and shows just how widespread the U-Boat threat was in the North Atlantic on just one day in 1942. It is easy to see how so many ships fell victim to this unseen threat but by this time in the war the wheels of fortune were turning against them as new technologies such as airborne radar meant that not even night provided cover for the U-Boat anymore. Nevertheless Allied losses continued right up to the end of the war and the lessons of the U-Boats were not lost on military planners in the Cold War.
