Lionel Crabb

Lionel "Buster" Crabb OBE, GM (28 January 1909 – presumed dead 19 April 1956) was a British Royal Navy frogman and MI6 diver who vanished during a reconnaissance mission around a Soviet cruiser in 1956.

Early life
Lionel Crabb was born on 28 January 1909 at 4 Greyswood Street, Streatham, South West London, the son of Hugh Alexander Crabb, a commercial traveller for a firm of photographic merchants, and his wife, Beatrice Goodall. They were a poor family. Little is known about Crabb's early life save that it was modestly commercial. While a youth he held many jobs, but also joined the Royal Naval Volunteer Reserve prior to World War II.

World War II
At the outbreak of World War II, 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.

He was one of a group of underwater clearance divers who checked for limpet mines in Gibraltar harbour during the period of Italian frogman and manned torpedo attacks. They dived with oxygen rebreathers Davis Submarine Escape Apparatus, which until then had not been used much if at all for swimming down from the surface. At first they swam by breaststroke without swimfins.

On 8 December 1942, during one such attack, two of the Italian frogmen, Lt. Visintini and Petty Officer Magro died, probably killed by depth charges. Their bodies were recovered, and their swimfins and Scuba sets were taken and from then on used by Sydney Knowles and Commander Lionel Crabb.

He was awarded the George Medal for his efforts and was promoted to Lieutenant Commander. In 1943 he became Principal Diving Officer for Northern Italy, 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.

By this time he had gained the nickname "Buster", named after U.S. 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 Irgun, the Zionist militant group. After 1947, he was demobilised from the military.

Civilian diver
Crabb moved to a civilian job and used his diving skills to explore the wreck of a Spanish galleon and he 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 — the HMS Truculent in January 1950 and HMS Affray in 1951 — to find out whether there were any survivors. Both efforts were 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.

In 1955 Crabb took frogman Sydney Knowles with him to investigate the hull of the Soviet cruiser Sverdlov 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, March 1955, Crabb was made to retire due to his age, but a year later he was recruited by MI6.

Disappearance
MI6 recruited Crabb in 1956 to investigate the Soviet cruiser Ordzhonikidze that had brought 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 the Ordzhonikidze's propeller — a new design that Naval Intelligence wanted to find out more about. On 19 April 1956 Crabb dived into Portsmouth Harbour and his MI6 controller never saw him again. Crabb's companion in the Sally Port Hotel took all his belongings and even the page of the hotel register where they had written their names. Ten days later British newspapers published stories about Crabb's disappearance in an underwater mission.

MI6 tried to cover up this espionage mission. On 29 April, under instructions from Rear Admiral J.G.T. Inglis OBE, the Director of Naval Intelligence, the Admiralty announced that Crabb had vanished when he had taken part in trials of secret underwater apparatus in Stokes Bay on the Solent. Soviets answered by releasing a statement stating that the crew of the Ordzhonikidze had seen a frogman near the cruiser on 19 April.

British newspapers speculated that Soviets had captured Crabb and taken him to the Soviet Union. The British Prime Minister Anthony Eden apparently disapproved of the fact that MI6 had operated without his consent in the UK (the preserve of the Security Service, "MI5"). It is mistakenly claimed that Eden forced director-general John Sinclair to resign following the incident. In fact, he had determined to replace Sinclair with MI5 director-general Dick White before the incident. Eden told MPs it was not in the public interest to disclose the circumstances in which the frogman met his end.

Body found
A little less than 14 months after Crabb's disappearance, on 9 June 1957, a body in a frogman suit was found floating off Pilsey Island in Chichester Harbour. It was missing its head and both hands, which made it impossible to identify (using then-available technology). Crabb's ex-wife was not sure enough to identify the body, nor was Crabb's girlfriend Pat Rose, though Sydney Knowles said that Crabb had had a similar scar on the left knee. An inquest jury returned an open verdict but the coroner announced that he was satisfied that the body was that of Lionel Crabb.

Fate
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. On 9 November 2007, The Independent reported how the government had covered up the death of 'Buster' 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 Ordzhonikidze hull near the ammunition depot and cut his throat. In an interview for a documentary film, Koltsov showed the dagger he allegedly used in a Russian documentary as well as an Order of the Red Star medal that he claimed to have been awarded for the deed. Koltsov, 74 at the time of the interview, stated that he wanted to clear his conscience and make known exactly what happened to Crabb.

It seems extremely unlikely that the British government would have tried to blow up a Soviet ship on a diplomatic mission while it was anchored in British waters, making Koltsov's claim of a mine suspect. It has even been suggested that Crabb was in fact, removing a mine fixed to the ship by a fanatical group of White Russians.

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 floating detention centre for suspected communists during the Indonesian killings of 1965–1966. The cruiser was scrapped in 1971.

Captured, brainwashed, defected or a double agent
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 prison 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; 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.

Shot in the water by a Soviet sniper
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. Official government documents regarding Crabb's disappearance are not scheduled to be released until 2057.

MI5 implication in death
On 26 March 2006, the Mail on Sunday published an article by Tim Binding entitled "Buster Crabb was murdered – by MI5". 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 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.

Second diver theory
Sydney Knowles, a former diving partner of Crabb's, stated on televised interview on Inside Out - South: 19 January 2007 for the BBC that Crabb didn't 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 the Ordzhonkidze while she was in Portsmouth Harbour.
