World War II Wrecks

Seven Valentine infantry tanks lie in the shallow waters of Studland Bay, left behind by the deadly rehearsals for D-Day. They went down in April 1944 during the top-secret Exercise "Operation Smash", when duplex-drive swimming modifications were on trial so that armour could float in to the Normandy beaches. The trials ended in tragedy: every one of the seven tanks sank, and six soldiers were killed. The tanks rest between 8 and 16 metres, crusted over with marine growth, and the sea life living around them has claimed them as its own. Two carry permanent buoys and are spaced roughly five metres apart. The site is a Scheduled Ancient Monument with strict legal protections, so nothing on it may be touched. These training relics belong to one of the lesser-known tragedies of the war.

The Dakotian's end came with shocking speed. A Heinkel 111H bomber dropped a parachute magnetic mine into Milford Haven in November 1940, and when it detonated against the anchored cargo steamer she went down in barely three minutes — one of the earliest parachute mine casualties in Welsh waters. What the site lacks in crystal water it makes up for in atmosphere: swimming along a 120-metre hull canted on its beam ends, knowing how suddenly and violently her war ended, gives the Dakotian a sombre character that clear-water wrecks sometimes lack.

This American Liberty ship was torpedoed by U-1195 off Eddystone Reef in March 1945 — one of the very last U-boat kills of the war — and sank in Whitsand Bay after an unsuccessful tow, mercifully without any loss of life. The structure teems with life: pollack shoal around the superstructure, conger eels lurk in the hull plating, and spider crabs carpet the decking in season.

Originally launched in the closing months of World War I as War Buffalo, the Persier spent her interwar years under the Belgian flag before the next conflict caught up with her. In February 1945, a torpedo struck her port side while she sailed in convoy just three miles from Eddystone. She limped into Bigbury Bay and grounded on a reef, where she remains today between 18 and 28 metres.

Bombed by a Luftwaffe Heinkel in the Firth of Lorn in December 1940, this Dutch cargo steamer was beached in Ardmucknish Bay — only for winter gales to drag her back into deeper water where she settled upright on the seabed. The superstructure sits between 11 and 19 metres, with the seabed at around 30. Marine growth is lush, with dahlia anemones, soft corals and shoals of pollack patrolling the companionways.

The P&O cargo liner Somali was bound for Hong Kong with nine thousand tons of wartime supplies — everything from medical kits and batteries to toy lead soldiers and coins for the colony's banks — when Luftwaffe Heinkels found her off Beadnell in March 1941. Bombs ignited her holds, and the resulting explosion broke the ship in two. Four cylinder heads rise above the surrounding structure like industrial sentinels, while five boilers arranged in neat rows forward give scale to what was a substantial ship. Marine growth has transformed every surface into a living wall of colour.

On the night of 14 October 1939, Kapitanleutnant Gunther Prien threaded U-47 through the supposedly impassable defences of Kirk Sound and put four torpedoes into a battleship at anchor. Eight hundred and thirty-five men — many of them boy sailors barely into their teens — died in the cold water of Scapa Bay. HMS Royal Oak now lies upturned in 33 metres, still weeping fuel oil after more than eight decades, marked by a green buoy bearing a simple request: respect their resting place. Every year, Royal Navy divers descend to replace the White Ensign on her hull, the only people authorised to visit a wreck protected under the highest classification of the Protection of Military Remains Act 1986. The sinking transformed Scapa Flow's defences: Churchill ordered permanent causeways across the eastern approaches, and Italian prisoners of war built the barriers that still carry Orkney's roads today.

At 43 metres on a rocky seabed near Baltimore, a German U-boat sits almost perfectly intact -- torpedoes still loaded in their tubes, the periscope glass unbroken, the Walter snorkel standing upright after eight decades on the bottom. U-260 was a Type VIIC submarine that struck a British mine approximately 32 kilometres south of the Fastnet Rock on 12 March 1945. The entire crew survived and were interned in Ireland for the rest of the war. Apart from mine damage to the bow, the hull is remarkably preserved. The conning tower, twin bronze propellers, and DF aerial all remain in place.

"LIGHTHOUSE SERVICE" -- the words were painted in five-foot letters on both sides of the hull. It made no difference. On 19 December 1940, the Irish Lights tender ILV Isolda left Rosslare Harbour carrying crew and Christmas provisions for the Barrels and Coningbeg lightships. Three miles out, with the Saltee Islands off her starboard beam, a German Focke-Wulf Fw 200 Condor attacked without warning and sank her. Six crew members from Dun Laoghaire were killed. Ireland was neutral. The Isolda was on a humanitarian mission to supply lighthouses. She was 198 feet long, 734 tonnes, built at Dublin Dockyard and launched on 26 January 1928. The sinking remains one of the most poignant examples of the dangers faced by neutral Ireland during the Second World War.

The Bellevue is notable for her unusual resting position, with her stern section pointing skyward from the seabed. This orientation is believed to be the result of a wartime mine encounter. Originally launched as the Escort in 1897, she was a steam-powered trawler built in Glasgow and later renamed Bellevue in 1922. Her final voyage ended in tragedy off the west coast, with the loss of all eight crew members. The wreck lies in the Firth of Clyde, where her triple expansion engine and stern section survive. Netting is reported on the wreck.

Ninety seconds. That was all the time between the torpedo impact and the Pinto disappearing beneath the Atlantic. She was doing what rescue ships do -- stationary, picking survivors from the water after U-482 had torpedoed the SS Empire Heritage just 30 minutes earlier. The same U-boat fired again, and the 1,346 GRT convoy rescue ship sank almost instantly. Captain Lawrence Boggs, M.B.E., was among the dead. Built in 1928 and converted for rescue service in May 1942, the Pinto had sailed with 10 convoys before her loss on 8 September 1944 while stationed with Convoy HX 305. The wreck at approximately 66 metres lies near the Empire Heritage wreck site, north-northeast of Tory Island.

She nearly changed the course of the war. U-2511 was the only operationally deployed Type XXI "Elektroboot" submarine in World War II -- the revolutionary design that could have devastated Allied shipping had it entered service earlier. Commanded by Korvettenkapitan Adalbert Schnee, she made one war patrol and had a British cruiser group in her sights before the ceasefire aborted the attack. Surrendered at Bergen, Norway, she was scuttled by Royal Navy gunfire on 7 January 1946 during Operation Deadlight after her towing cable parted. One of the most historically significant U-boat wrecks anywhere. Featured on BBC Dig WW2 with Dan Snow.

Sherman tanks sit upright on the seabed at 67 metres, some perfectly intact, others still racked neatly in the holds three deep. The SS Empire Heritage was a 15,702 GRT tanker carrying aviation fuel, tanks, and half-track military vehicles from New York as part of Convoy HX-305 when U-482 torpedoed her on 8 September 1944 approximately 20 nautical miles northwest of Malin Head. She went down in under five minutes, killing 113. Thirty minutes later, the same U-boat torpedoed the rescue vessel Pinto as she picked up survivors. The wreck is a designated war grave.

Built in 1925 by Fairfield Shipbuilding in Glasgow for the Anchor Line, she was requisitioned in August 1939 and converted to armed merchant cruiser F56, serving on the Northern Patrol. On 10 August 1940, U-56 torpedoed her approximately 40 nautical miles northwest of Malin Head. Taken in tow, she later foundered. Approximately 300 officers and ratings were rescued by nearby trawlers. The wreck requires a 3-4 hour boat transit from the Donegal coast.
