SUMMARY:HMS Flirt (1916)
DESCRIPTION:HMS Flirt wreck dive\nThe HMS Flirt wreck dive explores a Royal Navy destroyer lost during the Battle of Dover Strait in 1916. Flirt served with the Dover Patrol and helped guard the Dover Barrage. However\, on the night of 26/27 October 1916\, German torpedo boats raided the barrage and destroyed her at close range. \nThis HMS Flirt wreck dive carries one of the most dramatic stories off the Kent coast. Flirt moved towards gunfire to help the attacked drifters\, then launched a boat to rescue survivors. As a result\, the men in that boat became the main survivors when German torpedo boats overwhelmed the destroyer. \nHMS Flirt wreck dive: the ship before the battle\nCaptain E. R. G. R. Evans later captured Flirt’s character in Keeping the Seas. He described her as a dirty\, coal-fired\, pre-war destroyer that collected cinders across the bridge\, lifeboats and crowded deck\, yet still called her “a happy ship”. That small detail gives the wreck a human edge: Flirt was uncomfortable\, overworked and outdated\, but her crew carried on without complaint. \nPalmers Shipbuilding and Iron Company built HMS Flirt at Jarrow-on-Tyne. She launched on 15 May 1897 and reached Portsmouth in November 1898. Therefore\, by the time of her loss\, she already belonged to an older generation of Royal Navy destroyers. \nFlirt was one of the early 30-knot destroyers. She was small\, fast\, coal-fired and heavily worked. In addition\, she carried a 12-pounder gun\, five 6-pounder guns and torpedo tubes\, which made her useful for patrol and escort work. \nDuring the First World War\, Flirt served from Dover with the Sixth Destroyer Flotilla. Her job included patrol work\, anti-submarine duties and support for the Dover Barrage. Consequently\, she operated in one of the most dangerous and heavily contested sea lanes of the war. \nThe Battle of Dover Strait\nOn the night of 26/27 October 1916\, German torpedo boats from the Flanders Flotilla attacked the Dover Barrage. Their aim was to disrupt the British defences and damage the patrol vessels that guarded the Strait. The raid developed into the Battle of Dover Strait. \nThe German force first hit the drifter line. Flirt heard the firing and moved towards the danger. She found Waveney II burning or sinking and lowered a boat to rescue survivors. \nThen unidentified vessels approached. Flirt challenged them\, but the ships were German torpedo boats\, not friendly destroyers. They opened fire at close range\, and Flirt had little time to react. \nThe attack destroyed her rapidly. Accounts describe shellfire\, torpedo attack and damage to her boilers. Within minutes\, the destroyer sank in the Dover Strait. \nSixty of Flirt’s crew died\, while nine survived. Those survivors were mainly the men who had left the destroyer in the rescue boat. It is a brutal detail: the act of helping another stricken vessel saved the few men who lived. \nYou can read a detailed vessel history in History of War’s HMS Flirt profile. Meanwhile\, casualty and wreck-diving context appears in Scuba.To’s HMS Flirt article. \nThe wreck today\nFor divers\, HMS Flirt offers a powerful Dover Patrol wreck with a clear First World War story. She was not a merchant ship caught in the wrong place. She was a fighting destroyer on patrol\, destroyed during a German raid on the Dover Barrage. \nThe wreck also carries serious human weight. Sixty men died in the sinking\, and many appear on naval memorial records. Therefore\, this dive deserves quiet respect: look\, learn and leave the wreck alone. \nI would not describe HMS Flirt as a named Protected Place under the current Protection of Military Remains Act designation order without further official evidence. Even so\, the site is still a Royal Navy war loss with heavy loss of life. In practical terms\, treat it as a war grave\, not a rummage box with rivets. \nThis wreck gives divers a direct link to the Dover Patrol\, the Dover Barrage and the German night raids of 1916. Finally\, HMS Flirt reminds us that the Strait was not simply a shipping lane. It was a narrow battlefield\, and sometimes the rescue attempt became the trap. \nAre you a Mutiny Diver?

SUMMARY:Großes Torpedoboot SMS G-85 (1917)
DESCRIPTION:SMS G-85 wreck dive\nThe SMS G-85 wreck dive visits the remains of a German large torpedo boat lost during the Battle of Dover Strait in 1917. SMS G-85\, also written G85\, was not a cargo ship or civilian casualty. She was a fast Imperial German Navy warship sent into the Channel to attack the Dover Barrage. \nThis SMS G-85 wreck dive brings you close to one of the most dramatic night actions fought off the Kent coast. On 21 April 1917\, HMS Swift and HMS Broke intercepted German torpedo boats in a confused and violent clash. Therefore\, this is a wreck with a proper combat story\, not a polite little sinking caused by bad weather and poor life choices. \nSMS G-85 wreck dive: the ship before the battle\nSMS G-85 was a Großes Torpedoboot\, or large torpedo boat\, built for the Imperial German Navy. Germaniawerft built her at Kiel\, and she launched on 24 July 1915. She entered service later that year\, on 14 December 1915. \nAlthough called a torpedo boat\, G-85 was closer in role and size to an early destroyer. She measured about 83 m long\, carried three 10.5 cm guns and mounted six 50 cm torpedo tubes. In addition\, she could carry mines\, which made her useful for offensive raids in the North Sea and English Channel. \nBy spring 1917\, G-85 had joined German torpedo boat forces operating from Flanders. These fast ships targeted the Dover Patrol\, the Dover Barrage and Allied traffic moving through the Channel. As a result\, they posed a direct threat to the guarded sea route between Britain and the Western Front. \nThe Battle of Dover Strait\nOn the night of 20/21 April 1917\, fifteen German torpedo boats left Flanders in three groups. G-85 formed part of Gruppe Gautier\, alongside G42\, S53\, V71\, V73 and V81. Their orders were to attack the Dover Barrage and bombard Dover. \nThe German force first encountered the trawler Sabreur and opened fire. However\, Sabreur escaped with damage. Gruppe Gautier then shelled Dover\, where British coastal artillery replied before the German vessels turned back towards the Channel. \nDuring the withdrawal\, the British flotilla leaders HMS Swift and HMS Broke intercepted the German boats. In the darkness and confusion\, HMS Swift torpedoed G-85\, bringing her to a halt and setting her on fire. Meanwhile\, HMS Broke rammed G42\, and the two ships became locked together in a brutal close-quarters fight. \nAfter Broke broke clear from G42\, she moved towards the disabled G-85 and opened fire. Both German torpedo boats sank during the action. Thirty-five of G-85’s crew were killed\, although I have not found a reliable named casualty list in the accessible records. \nYou can read the main wreck record through Historic England’s Dover Strait wreck record. For a fuller account of the naval action\, see Naval-History.Net’s Dover destroyer action account. \nThe wreck today\nThe wreck site identification carries some historical caution. G42 and G-85 sank in the same battle\, and records have sometimes treated the two sites with uncertainty. Historic England notes a wreck believed to be G42 east of South Foreland\, while the site believed to be G-85 lies farther east. \nThat uncertainty adds interest rather than weakness. The wreck still represents one of the two German torpedo boats destroyed during the Battle of Dover Strait. For divers\, it offers a compact but powerful First World War story: speed\, darkness\, torpedoes\, ramming and the Dover Patrol doing its job with very little subtlety. \nAre you a Mutiny Diver?

SUMMARY:U-Boat SM UC-77 (1918)
DESCRIPTION:SM UC-77 wreck dive\nThe SM UC-77 wreck dive explores the story of a German Type UC II minelaying submarine lost during the final year of the First World War. UC-77 operated from Flanders and attacked Allied shipping with torpedoes\, gunfire and mines. Therefore\, this SM UC-77 wreck dive links the Dover Strait directly to the wider U-boat campaign. \nUC-77 had already built a serious record before her final patrol. Uboat.net credits her with 35 ships sunk and 7 damaged across 13 patrols. However\, in July 1918\, she tried to pass through the Dover Barrage and failed to return. \nSM UC-77 wreck dive: the submarine before the loss\nAG Vulcan built UC-77 at Hamburg as yard number 82. The German Navy ordered her on 12 January 1916\, launched her on 2 December 1916 and commissioned her on 29 December 1916. She first served under Kapitänleutnant Reinhart von Rabenau\, then under Oberleutnant zur See Johannes Ries. \nShe belonged to the Type UC II class\, a group of German minelaying submarines designed for offensive work in busy waters. UC-77 measured about 50.45 m overall and displaced about 410 tonnes on the surface. In addition\, she carried torpedoes\, a deck gun and 18 UC 200 mines. \nThat mine-carrying role made boats like UC-77 especially dangerous. They could attack a ship directly\, then leave mines in shipping lanes for later victims. As a result\, one patrol could create risk long after the submarine had left the area. \nThe Dover Barrage and final patrol\nBy 1918\, UC-77 operated with the Flandern flotillas from the Belgian coast. These boats targeted the Channel\, the North Sea approaches and Allied traffic moving around Britain and France. Meanwhile\, the British strengthened the Dover Barrage to block U-boats from passing through the Strait. \nUC-77 left for her final patrol in July 1918. Historic England records that she was outward-bound from Zeebrugge for operations off Portland and the Owers. However\, she never reached that patrol area. \nThe Dover Barrage account states that UC-77 dived while trying to pass through the defences\, but she left bubbles and leaking oil on the surface. The British drifters Kessingland and Golden Grain spotted the trail and attacked with depth charges. Then\, because UC-77 carried mines\, the explosions appear to have detonated some of her own ordnance. \nThe exact loss position remains disputed. Some records place the loss in the Dover Strait or off Folkestone\, while others refer to the Flanders coast or Fairy Bank. Therefore\, the safest wording is that UC-77 was lost during an attempted outward passage through the Dover Barrage in July 1918. \nYou can read the vessel and patrol summary in Uboat.net’s UC-77 record. The Kent wreck record and loss-position discussion appear in Historic England’s UC-77 entry. \nThe wreck today\nFor divers\, UC-77 offers a powerful First World War submarine story with genuine historical tension. She was not a passive casualty. She had sunk or damaged dozens of vessels before her own final encounter with the Dover defences. \nAll 30 men aboard died\, including Oberleutnant zur See Johannes Ries. I have not found a complete reliable open list of the crew in the accessible sources\, so the event page should avoid naming men beyond those confirmed by reliable records. Even so\, the casualty figure gives the wreck clear war-grave weight. \nThe dive also gives context to the Dover Strait itself. This was not an empty stretch of water between England and France. It was a defended\, mined\, patrolled and contested choke point. UC-77 reminds us that the seabed off Kent still holds the hard evidence of that fight. \nAre you a Mutiny Diver? Book more dives.

SUMMARY:U-Boat SM UB-109 (1918)
DESCRIPTION:SM UB-109 wreck dive\nThe SM UB-109 wreck dive explores the remains of a German Type UB III submarine lost off Folkestone in 1918. UB-109 had completed a dangerous Atlantic patrol and was trying to return through the Dover Barrage when British shore-controlled mines destroyed her. As a result\, twenty-eight men died and eight survived. \nThis SM UB-109 wreck dive tells one of the sharper late-war Dover Strait stories. The submarine passed through the barrage on her outward journey\, but British forces changed the defences while she remained at sea. Therefore\, when UB-109 returned\, the route she expected to use had become a trap. \nSM UB-109 wreck dive: the submarine before the loss\nBlohm & Voss built UB-109 at Hamburg as yard number 315. Germany ordered her on 23 September 1916\, launched her on 7 July 1917 and commissioned her on 31 December 1917. Kapitänleutnant Kurt Ramien commanded her throughout her operational career. \nUB-109 belonged to the Type UB III class. These submarines worked as seagoing attack boats\, larger and more capable than the earlier coastal UB types. They carried torpedoes and a deck gun\, which allowed them to attack merchant shipping across wider patrol areas. \nBy March 1918\, UB-109 had joined the Flandern I Flotilla. From the Belgian coast\, these boats threatened shipping in the Channel\, the North Sea and the Atlantic approaches. Consequently\, the Dover Strait became both an escape route and a killing ground. \nThe final patrol and the Folkestone Gate\nUB-109 left Zeebrugge in the early hours of 28 July 1918. She passed through the Dover Barrage outward-bound and headed towards the Atlantic. During that patrol\, she added to a wartime record that eventually reached seven ships sunk\, totalling 14\,092 tons. \nHowever\, the British improved the Dover Barrage while Ramien and his crew were away. The Folkestone Gate had allowed friendly surface traffic through the mine defences. Then British forces closed the gap with shore-controlled mines linked to detection systems. \nOn 29 August 1918\, UB-109 tried to return through the same general route. A patrol vessel appears to have forced her to alter course and submerge. Then the shore-controlled minefield detonated as she crossed the defended area. \nThe explosion broke the submarine and flooded her fast. Eight men escaped and were taken prisoner\, but twenty-eight died. British naval divers reached the wreck quickly afterwards and recovered valuable intelligence material from the boat. \nYou can read the vessel record in Uboat.net’s UB-109 entry. Historic England’s archaeological summary appears in Historic England’s UB-109 wreck record. \nThe wreck today\nThe wreck lies off Folkestone and forms part of the wider archaeology of the Dover Barrage. Historic England records the site in territorial waters at about 51°03.731’N\, 001°14.146’E. The archaeological survey found the submarine in two main sections. \nThe forward section remains upright\, while the smaller stern section lies upside down to the south-west. The break sits aft of the conning tower area\, which fits the expected damage from the shore-controlled mine detonation. In addition\, survey records note the 8.8 cm gun\, the partly extended attack periscope and the sand-filled hull. \nFor divers\, UB-109 offers more than a submarine silhouette on the seabed. It shows how the Dover Barrage developed into a deadly system of mines\, listening stations\, patrol vessels and intelligence work. Finally\, it gives the dive real human weight: thirty-six men entered the barrage\, eight came out alive. \nAre you a Mutiny Diver? Book more dives.

SUMMARY:U-Boat SM UB-78 (1918)
DESCRIPTION:SM UB-78 wreck dive\nThe SM UB-78 wreck dive explores a German Type UB III submarine lost off Dover in 1918. UB-78 tried to pass through the heavily defended Dover Strait\, but a mine stopped her final patrol. As a result\, all 35 men aboard died. \nThis SM UB-78 wreck dive takes you into one of the hardest First World War choke points around the Kent coast. By 1918\, the Dover Barrage had become a serious obstacle for U-boats operating from Flanders. Therefore\, any submarine trying to force the Strait faced mines\, patrol craft\, nets\, lights and listening systems. \nSM UB-78 wreck dive: the submarine before the loss\nBlohm & Voss built UB-78 at Hamburg as yard number 307. Germany ordered her on 23 September 1916\, launched her on 2 June 1917 and commissioned her on 20 October 1917. During her short career\, three officers commanded her: Woldemar Petri\, Ulrich Pilzecker and Arthur Stoßberg. \nUB-78 belonged to the Type UB III class. These late-war submarines carried torpedoes\, an 8.8 cm deck gun and enough range to threaten Allied shipping beyond the immediate Belgian coast. In addition\, their size and capability made them far more dangerous than the small early-war coastal boats. \nShe first served with the V Flotilla\, then joined the Flandern I Flotilla in February 1918. From there\, she took part in the U-boat campaign against Allied traffic in and around the Channel. Uboat.net credits her with two ships sunk and two ships damaged during five patrols. \nThe mine loss off Dover\nOn 19 April 1918\, UB-78 attempted to pass through the Dover Strait. However\, the British had strengthened the Dover Barrage into a layered defensive barrier. Mines formed a central part of that system\, supported by patrol vessels and other detection methods. \nUB-78 struck a mine off Dover and sank with all hands. Uboat.net records the loss position as 51.01N\, 01.17E. Meanwhile\, Wessex Archaeology describes the wreck as lying off Folkestone\, where later survey work recorded the submarine in two main sections. \nThe wreck evidence fits a violent mine loss. Wessex Archaeology records that the submarine lies almost fully exposed and split into two sections. In addition\, the report states that the separation probably happened during the sinking\, after one or more mine explosions. \nYou can read the vessel record in Uboat.net’s UB-78 entry. Meanwhile\, the archaeological survey background appears in Wessex Archaeology’s UB-78 survey note. \nThe wreck today\nSM UB-78 is a Protection of Military Remains Act 1986 designation order. Divers may visit the site\, but they must not disturb the wreck\, recover artefacts or enter the submarine. In practical terms\, this is a look-only war grave dive\, and the site deserves the same respect you would give any military maritime grave. \nFor divers\, UB-78 offers a powerful Dover Strait submarine wreck with clear First World War context. The site lies off Folkestone and forms part of the wider military landscape of the Dover Barrage. Therefore\, the dive connects directly with the British effort to close the Channel route to German submarines. \nThe wreck also carries war-grave weight. All 35 men aboard died\, including the final commander\, Oberleutnant zur See Arthur Stoßberg. As always with U-boat wrecks\, divers should treat the site with respect and avoid disturbance\, because the seabed is not a souvenir counter\, despite humanity’s heroic efforts to behave otherwise. \nOlder sources confused UB-78 with UC-78 and with a ramming incident involving the troopship Queen Alexandra. However\, Uboat.net now records that local divers discovered and identified UB-78\, while the Queen Alexandra incident accounted for UC-78. Consequently\, the Folkestone wreck is best treated as UB-78\, lost to a Dover Barrage mine on 19 April 1918. \nAre you a Mutiny Diver? Book more dives.

SUMMARY:U-Boat SM UB-33 (1918)
DESCRIPTION:SM UB-33 wreck dive\nThe SM UB-33 wreck dive explores a German Type UB II submarine lost in the Dover Barrage in 1918. UB-33 had completed 17 patrols and had already built a record of sinkings before she tried to pass the Varne Bank route. However\, on 11 April 1918\, a British mine ended her final passage. \nThis SM UB-33 wreck dive gives you a compact but serious First World War submarine story. The wreck connects the Flanders U-boat campaign\, the Dover Barrage and the dangerous minefields that guarded the Channel. As a result\, the dive has clear historical weight before you even reach the seabed. \nSM UB-33 wreck dive: the submarine before the loss\nBlohm & Voss built UB-33 at Hamburg as yard number 257. Germany ordered her on 22 July 1915\, launched her on 5 December 1915 and commissioned her on 20 April 1916. During her career\, several officers commanded her\, with Oberleutnant zur See Fritz Gregor in command at the time of loss. \nUB-33 belonged to the Type UB II class. These submarines improved on the smaller early UB boats and gave Germany a more useful coastal attack platform. In addition\, UB-33 carried torpedoes and a deck gun\, which allowed her to threaten merchant vessels across several patrol areas. \nShe first served with the Baltic Flotilla\, then transferred to the Flandern Flotilla in October 1917. From the Belgian coast\, German submarines could attack shipping around the Channel and southern North Sea. Consequently\, the Dover Strait became one of the most heavily defended stretches of water in the First World War. \nThe Dover Barrage and the Varne Bank route\nBy 1918\, the Dover Barrage formed a major obstacle for German submarines trying to move between Flanders and the wider Atlantic approaches. Mines\, patrol craft and other defences all worked together to make the Strait dangerous. Therefore\, any U-boat using the route took a serious risk. \nOn 11 April 1918\, UB-33 took the Varne Bank route through the British minefields. She struck a mine south-west of the Varne sandbank and sank. Uboat.net records the loss position as 50°55’N\, 01°17’E\, while Historic England links the loss directly to the Dover Barrage. \nAll hands died. Uboat.net records 28 dead\, including the final commander\, Fritz Gregor. Historic England notes some older disagreement over the crew figure\, but the clearest working figure for the event page is 28 lost. \nRoyal Navy divers visited the wreck on 29 May 1918\, only weeks after the sinking. They entered the submarine and recovered confidential German documents\, including code books and ciphers. That recovery gave UB-33 an intelligence story as well as a battlefield story. \nYou can read the vessel record in Uboat.net’s UB-33 entry. Meanwhile\, Historic England records the loss and Royal Navy diving recovery in Historic England’s UB-33 wreck record. \nThe wreck today\nFor divers\, UB-33 offers a serious Dover Strait submarine wreck with clear wartime context. The site represents the deadly pressure placed on Flanders U-boats as they tried to move through the Channel. In addition\, the Varne Bank setting links the wreck directly with the mine warfare that shaped this part of the war at sea. \nI would treat UB-33 as a war grave in practical and moral terms. However\, I would not describe her as a current Protected Place under the Protection of Military Remains Act 1986 unless further legal evidence confirms that status. Either way\, the site deserves careful\, respectful diving: no disturbance\, no recovery and no behaviour that would embarrass a reasonably trained mammal. \nThe wreck gives you more than a submarine outline. It tells a story of patrols\, minefields\, lost crew and wartime intelligence work. Finally\, it reminds us that the Dover Strait was not a simple route home. For UB-33\, it became the final barrier. \nAre you a Mutiny Diver? Book more dives.

SUMMARY:U-Boat SM UB-55 (1918)
DESCRIPTION:SM UB-55 wreck dive\nThe SM UB-55 wreck dive explores a German Type UB III submarine lost in the Dover Barrage in 1918. UB-55 left Zeebrugge for another patrol\, then struck a mine while trying to pass through the Strait of Dover. As a result\, 30 men died and 6 survived. \nThis SM UB-55 wreck dive gives you a serious late-war U-boat story with a direct Kent coast connection. By April 1918\, the Dover Barrage had become a deadly barrier of mines\, patrol vessels and detection systems. Therefore\, any Flanders U-boat trying to reach open water faced a very dangerous passage. \nSM UB-55 wreck dive: the submarine before the loss\nA.G. Weser built UB-55 at Bremen as yard number 267. Germany ordered her on 20 May 1916\, laid her down on 5 September 1916 and commissioned her on 1 July 1917. Kapitänleutnant Ralph Wenninger commanded her throughout her active career. \nUB-55 belonged to the Type UB III class. These submarines gave Germany a more capable seagoing attack boat than the earlier coastal UB types. In addition\, they carried torpedoes and an 8.8 cm deck gun\, which allowed them to attack merchant shipping across wider patrol areas. \nShe joined the Flandern Flotilla in August 1917. From the Belgian coast\, boats like UB-55 threatened Allied shipping in the Channel\, the southern North Sea and the Atlantic approaches. Consequently\, the Dover Strait became both a route out and a trap on the way through. \nThe Dover Barrage mine loss\nOn 22 April 1918\, UB-55 tried to pass through the Dover Barrage while outbound from Zeebrugge. Uboat.net records that she sank at 51°01’N\, 1°20’E after striking a mine. Thirty men died\, while six survived. \nHistoric England records a detailed survivor-based account. UB-55 approached the minefield on the surface\, then dived at about 4 am. Soon afterwards\, the crew heard cables scraping along the hull\, followed by an explosion that flooded the aft section and forced the submarine to the bottom. \nAt least some of the crew escaped through the forward and conning tower hatches as water rose inside the boat. Drifters later picked up six survivors and one body. Therefore\, the wreck was not a mystery loss: the survivors confirmed the submarine as UB-55. \nThe casualty figures vary slightly in older records. However\, the clearest working figure for this event page is 30 dead and 6 survivors. That keeps the story readable without turning the page into an argument over archival arithmetic\, which is how joy goes to die. \nYou can read the vessel record in Uboat.net’s UB-55 entry. Meanwhile\, Historic England records the loss\, wreck identification and later archaeological notes in Historic England’s UB-55 wreck record. \nThe wreck today\nFor divers\, UB-55 offers a compact but powerful Dover Strait submarine wreck. Survey records place the wreck about 10 km south of Dover\, with the site lying upright in around 30 m of water. In addition\, Historic England records that the pressure hull lies open just aft of the conning tower. \nRoyal Navy divers located and identified the wreck during the war. They recovered the 8.8 cm deck gun and sent material to London. Later records also note recovered small artefacts\, although modern divers should treat the site with restraint and respect. \nI would treat UB-55 as a war grave in practical and moral terms. However\, I would not describe her as a current Protected Place under the Protection of Military Remains Act 1986 unless separate legal evidence confirms that status. Either way\, this is a look\, learn and leave-alone wreck. \nThe dive tells a sharp story: a successful U-boat\, a mined barrier\, six survivors and thirty men left inside the consequences. Finally\, UB-55 reminds us that the Dover Barrage did not merely defend a coastline. It turned the Strait into a killing ground for submarines trying to pass through. \nUB-55 also has a remarkable postscript. Her commander\, Ralph Wenninger\, survived the sinking and later joined the Luftwaffe\, eventually rising to the rank of General der Flieger during the Second World War. \nAre you a Mutiny Diver?

SUMMARY:U-Boat SM UB-109 (1918)
DESCRIPTION:SM UB-109 wreck dive\nThe SM UB-109 wreck dive explores the remains of a German Type UB III submarine lost off Folkestone in 1918. UB-109 had completed a dangerous Atlantic patrol and was trying to return through the Dover Barrage when British shore-controlled mines destroyed her. As a result\, twenty-eight men died and eight survived. \nThis SM UB-109 wreck dive tells one of the sharper late-war Dover Strait stories. The submarine passed through the barrage on her outward journey\, but British forces changed the defences while she remained at sea. Therefore\, when UB-109 returned\, the route she expected to use had become a trap. \nSM UB-109 wreck dive: the submarine before the loss\nBlohm & Voss built UB-109 at Hamburg as yard number 315. Germany ordered her on 23 September 1916\, launched her on 7 July 1917 and commissioned her on 31 December 1917. Kapitänleutnant Kurt Ramien commanded her throughout her operational career. \nUB-109 belonged to the Type UB III class. These submarines worked as seagoing attack boats\, larger and more capable than the earlier coastal UB types. They carried torpedoes and a deck gun\, which allowed them to attack merchant shipping across wider patrol areas. \nBy March 1918\, UB-109 had joined the Flandern I Flotilla. From the Belgian coast\, these boats threatened shipping in the Channel\, the North Sea and the Atlantic approaches. Consequently\, the Dover Strait became both an escape route and a killing ground. \nThe final patrol and the Folkestone Gate\nUB-109 left Zeebrugge in the early hours of 28 July 1918. She passed through the Dover Barrage outward-bound and headed towards the Atlantic. During that patrol\, she added to a wartime record that eventually reached seven ships sunk\, totalling 14\,092 tons. \nHowever\, the British improved the Dover Barrage while Ramien and his crew were away. The Folkestone Gate had allowed friendly surface traffic through the mine defences. Then British forces closed the gap with shore-controlled mines linked to detection systems. \nOn 29 August 1918\, UB-109 tried to return through the same general route. A patrol vessel appears to have forced her to alter course and submerge. Then the shore-controlled minefield detonated as she crossed the defended area. \nThe explosion broke the submarine and flooded her fast. Eight men escaped and were taken prisoner\, but twenty-eight died. British naval divers reached the wreck quickly afterwards and recovered valuable intelligence material from the boat. \nYou can read the vessel record in Uboat.net’s UB-109 entry. Historic England’s archaeological summary appears in Historic England’s UB-109 wreck record. \nThe wreck today\nThe wreck lies off Folkestone and forms part of the wider archaeology of the Dover Barrage. Historic England records the site in territorial waters at about 51°03.731’N\, 001°14.146’E. The archaeological survey found the submarine in two main sections. \nThe forward section remains upright\, while the smaller stern section lies upside down to the south-west. The break sits aft of the conning tower area\, which fits the expected damage from the shore-controlled mine detonation. In addition\, survey records note the 8.8 cm gun\, the partly extended attack periscope and the sand-filled hull. \nFor divers\, UB-109 offers more than a submarine silhouette on the seabed. It shows how the Dover Barrage developed into a deadly system of mines\, listening stations\, patrol vessels and intelligence work. Finally\, it gives the dive real human weight: thirty-six men entered the barrage\, eight came out alive. \nAre you a Mutiny Diver? Book more dives.
