Documented maritime mysteries from The Cold File.https://thecoldfile.com/https://thecoldfile.com/articles/1845-franklin-expedition/https://thecoldfile.com/articles/1845-franklin-expedition/A printed Admiralty form in a stone cairn on King William Island records that 105 men abandoned HMS Erebus and HMS Terror on 22 April 1848. None reached help. For 180 years the cumulative cause of their deaths has been contested, even after Inuit oral history guided Parks Canada to the wreck of Erebus in 2014 and the Arctic Research Foundation to Terror in 2016.Mon, 15 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1921-uss-conestoga/https://thecoldfile.com/articles/1921-uss-conestoga/A 170-foot US Navy ocean tug cleared the Golden Gate in March 1921 and disappeared with all 56 of her crew. The wreck was located in 2009 and identified by NOAA and the Navy in March 2016, ninety-five years almost to the day after she sailed; the cause of her loss remains officially undetermined.Tue, 09 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1975-berge-istra/https://thecoldfile.com/articles/1975-berge-istra/A 227,550 dwt Liberian-flagged, Norwegian-owned ore-bulk-oil carrier on a Tubarão-to-Kimitsu iron-ore voyage with a crew of 32 went silent in the western Pacific southeast of Mindanao on or about 29 to 30 December 1975; nineteen days later, the Japanese fishing vessel Hachi-O-Maru 6 picked up two Canarian able seamen, Imeldo Barreto León and Epifanio Perdomo López, on an improvised raft, the only survivors; the Liberian flag-state inquiry attributed the loss to an internal explosion of hydrocarbon vapours but did not publish its full findings; no wreckage has ever been recovered.Tue, 09 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1880-hms-atalanta/https://thecoldfile.com/articles/1880-hms-atalanta/HMS Atalanta departed the Royal Naval Dockyard, Bermuda, on 31 January 1880 with 281 officers, ratings, boy seamen, and Royal Marines, met the documented Atlantic gale of 12 to 16 February 1880, and was never seen again; the Committee of Inquiry of 29 December 1880 returned no reliable cause, the wreck has never been located, and 146 years on the loss is still unresolved.Mon, 08 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1925-ss-cotopaxi/https://thecoldfile.com/articles/1925-ss-cotopaxi/A coal-laden bulk freighter cleared Charleston on 29 November 1925, transmitted a wireless distress reporting a list in a tropical storm on or about 1 December, and never reached Havana. Ninety-five years later a wreck thirty-five nautical miles off St Augustine was identified as her hull. The cause of her loss is still open.Sun, 07 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1968-k-129/https://thecoldfile.com/articles/1968-k-129/A Soviet ballistic missile submarine went down in the North Pacific in March 1968. Six years later the CIA used a purpose-built ship to lift part of her from 16,500 feet, the operation broke into the press in 1975, and a 1976 FOIA case turned the agency's silence into a doctrine. The cause of the sinking is still contested.Sun, 07 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1893-ss-naronic/https://thecoldfile.com/articles/1893-ss-naronic/A near-new White Star cattle and cargo steamer left Liverpool for New York on 11 February 1893 with 74 souls aboard and was never seen again. The first physical trace was two empty lifeboats sighted by another ship three weeks later. A Board of Trade inquiry could not fix the cause and 132 years on the loss is still unsolved.Sat, 06 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1951-hms-affray/https://thecoldfile.com/articles/1951-hms-affray/A Royal Navy training submarine dived in the English Channel on the evening of 16 April 1951 and never surfaced. A Board of Inquiry identified material failure of her snort mast as the most likely immediate cause. Seven months later the First Lord of the Admiralty told the House of Commons there was insufficient evidence to enable him to say with certainty why Affray was lost. The Director of Naval Construction reportedly disagreed with the Board in private. Seventy-five years on, the Ministry of Defence has not revised that position.Wed, 03 Jun 2026 00:00:00 GMThttps://thecoldfile.com/articles/1964-bouvet-lifeboat/https://thecoldfile.com/articles/1964-bouvet-lifeboat/On 2 April 1964, a Royal Navy helicopter put a survey party from HMS Protector down on a low strip of jumbled rock on the northwest coast of Bouvet Island. About two hundred yards inland, in a small lagoon already occupied by a colony of fur seals, the party found a half-swamped, twenty-foot lifeboat with no markings, no log, and no human remains. On the rocks nearby were a forty-four-gallon drum, a pair of oars, pieces of wood, and a copper buoyancy tank hammered out flat. No vessel of origin has ever been identified in any reputable record. Sixty-two years on, the file is still open.Fri, 29 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1955-mv-joyita/https://thecoldfile.com/articles/1955-mv-joyita/A 69-foot wooden cabin cruiser sailed from Apia for the Tokelau Islands on 3 October 1955 with 25 people aboard, missed her destination, and was found five weeks later drifting derelict more than 600 miles west of her route. A New Zealand Crown Commission of Inquiry established how she flooded but declared the fate of the 25 inexplicable on the evidence submitted.Thu, 28 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1963-marine-sulphur-queen/https://thecoldfile.com/articles/1963-marine-sulphur-queen/A T-2 tanker converted to carry molten sulfur sailed from Beaumont in February 1963 and vanished in the Gulf of Mexico west of the Florida Keys with all thirty-nine crew. The US Coast Guard's Marine Board could not determine the cause and listed four possible scenarios it declined to rank. Eight years later, the Second Circuit found the vessel unseaworthy but denied punitive damages on the ground that no one knows how the ship was lost.Thu, 28 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1968-uss-scorpion/https://thecoldfile.com/articles/1968-uss-scorpion/A US Navy nuclear attack submarine was lost with all 99 crew in deep water southwest of the Azores in May 1968. The Navy's own Court of Inquiry concluded the certain cause could not be ascertained, a separate Navy engineering panel reached a different conclusion, and fifty-seven years later the responsible bodies still do not agree on which failure killed her.Thu, 28 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1978-mv-munchen/https://thecoldfile.com/articles/1978-mv-munchen/A modern West German LASH carrier vanished in an exceptional North Atlantic storm in December 1978, leaving only fragmentary distress signals, scattered debris, and a starboard lifeboat whose davit pins had been bent fore to aft some twenty metres above her waterline. The storm broke her. The specific mechanism that destroyed her so quickly is what the Seeamt Bremerhaven could not establish, and what the case is still about.Thu, 28 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1909-ss-waratah/https://thecoldfile.com/articles/1909-ss-waratah/A year-old Blue Anchor liner left Durban for Cape Town in July 1909 with 211 people aboard, was last seen by another ship the next morning, and vanished in a gale with no wreckage, no bodies, and, to this day, no confirmed wreck. A 14-month British inquiry could not fix the cause. The central question of whether she was dangerously unstable was contested at that inquiry, and more than a century of searches has found nothing.Tue, 26 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1975-edmund-fitzgerald/https://thecoldfile.com/articles/1975-edmund-fitzgerald/The largest ship on the Great Lakes vanished from a companion vessel's radar in under ten minutes, with no distress call, on a November night in 1975. The storm sank her. Which failure delivered the killing blow is the part three official investigations could never agree on.Tue, 26 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1918-uss-cyclops/https://thecoldfile.com/articles/1918-uss-cyclops/A 540-foot Navy collier with about 300 people aboard left Barbados for Baltimore in March 1918 and was never seen again, the largest non-combat loss of life in United States Navy history. The official cause is still unknown. The leading engineering explanation lies in the dense manganese ore she carried, and in two sister ships later lost the same way, while the wartime treachery suspicions and the Bermuda Triangle framing are things the record does not support.Mon, 25 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1921-carroll-deering/https://thecoldfile.com/articles/1921-carroll-deering/A near-new five-masted schooner was found hard aground on Diamond Shoals with every sail set, both lifeboats gone, her steering smashed, and her crew of about eleven never seen again. Here the eerie details are mostly real, recorded by the Coast Guard and a five-department federal investigation. The certainty of a pirate capture rested on a confessed hoax, and the Bermuda Triangle is a later overlay on a 1921 event.Mon, 25 May 2026 00:00:00 GMThttps://thecoldfile.com/articles/1872-mary-celeste/https://thecoldfile.com/articles/1872-mary-celeste/A seaworthy American brigantine was found adrift east of the Azores with her one boat gone and ten people missing. The famous version, with its warm breakfast and untouched coffee, is fiction. The documented case is stranger, and harder to close.Sun, 24 May 2026 00:00:00 GMT
