Lionel Crabb

On 16 November 2007, the BBC and the Daily Mirror reported that Eduard Koltsov, a Soviet frogman, claimed to have caught Crabb placing a mine on the hull of Ordzhonikidze and cut his throat. In an interview for a Russian documentary film, Koltsov showed the dagger he claimed to have used, as well as an Order of the Red Star medal that he said had been awarded for the deed. A Russian journalist from the military newspaper Krasnaya Zvezda considered Koltsov's story improbable. In particular, the archive documents did not confirm that Koltsov, a bus driver in Rostov-on-Don for 30 years, had been awarded the Order of the Red Star or was a Soviet Navy frogman.

As information was declassified under the 50-year rule, new facts on Crabb's disappearance came to light. On 27 October 2006, the National Archives released papers relating to the fatal Ordzhonikidze mission. Sydney Knowles, a former diving partner of Crabb's, stated in a televised interview on Inside Out – South on 19 January 2007 that Crabb did not dive alone on his fatal last mission: "He told me they'd given him a buddy diver." Furthermore, papers released under the Freedom of Information Act indicate that there were other divers investigating Ordzhonikidze while the ship was in Portsmouth Harbour. On 9 November 2007, The Independent reported how the government had covered up the death of 'Buster' Crabb.

Tim Binding wrote a fictionalised account of Crabb's life, Man Overboard which was published by Picador in 2005. Binding stated that, following the book's publication, he was contacted by Sydney Knowles. Binding alleged that he then met Knowles in Spain and was told that Crabb was known by MI5 to have intentions of defecting to the USSR. This would have been embarrassing for the UK — Crabb being an acknowledged war hero. Knowles has suggested that MI5 set up the mission to the Ordzhonikidze specifically to murder Crabb, and supplied Crabb with a new diving partner who was under orders to kill him. Binding stated Knowles alleged that he was ordered by MI5 to identify the body found as Crabb, when he knew it was definitely not Crabb. Knowles went along with the deception. Knowles has also alleged that his life was threatened in Torremolinos in 1989, at a time when Knowles was in discussions with a biographer. About the claims that Crabb was planning to defect to the Soviet Union, Reg Vallintine of the Historical Diving Society was quoted as saying: "Diving historians find it very hard to believe that this man, who prided himself on being a patriot, would have seriously considered defecting. Crabb was very fond of being a hero, and it is hard to imagine him jeopardising that status." It is not clear just why MI6 would recruit a man who was known to be planning to defect to the Soviet Union to spy against the Soviet Union or why Crabb would agree to such a mission if he really had decided that he wanted to live in the Soviet Union.

In a war documentary series titled Secrets of War, episode titled "The Cold War. Khrushchev's Regime", a 1996 interview with former head of the KGB Vladimir Semichastny (who was the first secretary of Komsomol at the time of Crabb's disappearance) reported, Crabb's decapitated body was found floating in the harbour two months after his disappearance. In the interview, Semichastny states that the "Crabb Affair" was handled elegantly.

In a 1990 interview, Joseph Zwerkin, a former member of Soviet Naval intelligence, who had moved to Israel after the breakup of the Soviet Union, claimed that the Soviets had noticed Crabb in the water and that a Soviet sniper had shot him.

The cruiser Ordzhonikidze was later transferred by the Soviet government to Indonesia in 1962, where it operated as KRI Irian. The ship operated in the conflict against the Netherlands over West Papua, and was later used as a floating detention centre for suspected communists during the Indonesian killings of 1965–1966. The cruiser was scrapped in 1971.

Certain Members of Parliament and Michael Hall became concerned about Crabb's ultimate fate and in 1961, Commander J.S. Kerans (and later in 1964 Marcus Lipton) submitted proposals to re-open the case but were rebuffed. Various people speculated that Crabb had been killed by some secret Soviet underwater weapon; that he had been captured and imprisoned in Lefortovo prison with prisoner number 147, that he had been brainwashed to work for the Soviet Union to train their frogman teams; that he had defected and became a commander in the Soviet Navy under the assumed name of Leonid Krabov; that he was in the Soviet Special Task Underwater Operational Command in the Black Sea Fleet; or that MI6 had asked him to defect so he could become a double agent.

A little less than 14 months after Crabb's disappearance, on 9 June 1957, a body in a diving suit was brought to the surface in their net by two fishermen off Pilsey Island in Chichester Harbour. The body was brought to shore in a landing craft operated by members of RAF Marine Craft Unit No. 1107.

MI6 recruited Crabb in 1956 to investigate the Soviet cruiser Ordzhonikidze that had taken head of state Nikita Khrushchev and Nikolai Bulganin on a diplomatic mission to Britain. According to Peter Wright in his book Spycatcher (1987), Crabb was sent to investigate Ordzhonikidze' s propeller, a new design that Naval Intelligence wanted to examine. On 19 April 1956, Crabb dived into Portsmouth Harbour and his MI6 controller never saw him again. Years later, a Russian who had been on board Ordzhonikidze claimed that the Soviets were expecting him that night (after being tipped of the British operation by a mole), and that he dived into the dark and dirty waters beneath the Ordzhonikidze, hunted down Crabb, slit his air hose and his throat with a knife. Crabb's companion in the Sally Port Hotel took all his belongings and even the page of the hotel register on which they had written their names. Ten days later British newspapers published stories about Crabb's disappearance in an underwater mission.

In 1955, Crabb took frogman Sydney Knowles with him to investigate the hull of a Soviet Sverdlov-class cruiser to evaluate its superior manoeuvrability. According to Knowles, they found a circular opening at the ship's bow and inside it a large propeller that could be directed to give thrust to the bow. That same year, in March, Crabb was made to retire due to his age, but a year later he was recruited by MI6. By that time, Crabb's heavy drinking and smoking had taken its toll on his health, and he was not the diver that he had been in World War II.

By this time, he had gained the nickname "Buster", after the American actor and swimmer Buster Crabbe. After the war, Crabb was stationed in Palestine and led an underwater explosives disposal team that removed mines placed by Jewish divers from the Palyam, the maritime force of the Palmach elite Jewish fighting force during the years of Mandatory Palestine. After 1947, he was demobilised from the military.

Crabb was awarded the George Medal for his efforts and was promoted to lieutenant commander. In 1943 he became Principal Diving Officer for Northern Italy, and was assigned to clear mines in the ports of Livorno and Venice; he was later created an Officer of the Order of the British Empire for these services. He was also an investigating diver in the suspicious death of General Sikorski of the Polish Army, whose B-24 Liberator aircraft crashed near Gibraltar in 1943.

On 8 December 1942, during one such attack, two of the Italian frogmen, Lieutenant Visintini and Petty Officer Magro, died, probably killed by small explosive charges thrown from harbour-defence patrol boats, a tactic said to have been introduced by Crabb. Their bodies were recovered, and their swimfins and Scuba sets were taken and from then on used by Sydney Knowles and Crabb.

At the outbreak of the Second World War, Crabb was first an army gunner. Then, in 1941, he joined the Royal Navy. The next year he was sent to Gibraltar where he worked in a mine and bomb disposal unit to remove the Italian limpet mines that enemy divers had attached to the hulls of Allied ships. Initially, Crabb's job was to disarm mines that British divers removed, but eventually he decided to learn to dive.

Lionel Crabb was born on January 28, 1909 in London, England.

Crabb moved to a civilian job and used his diving skills to explore the wreck of a Spanish galleon from the 1588 Armada, off Tobermory on the Isle of Mull. He then located a suitable site for a discharge pipe for the Atomic Weapons Research Establishment at Aldermaston. He later returned to work for the Royal Navy. He twice dived to investigate sunken Royal Navy submarines — HMS Truculent in January 1950 and HMS Affray in 1951 — to find out whether there were any survivors. Both efforts proved fruitless. In 1952, Crabb married Margaret Elaine Player, the daughter of Henry Charles Brackenbury Williamson and the former wife of Ernest Albert Player. The couple separated in 1953 and divorced about two years later.
