    • Air Commodore Jeaffreson Greswell, who has died aged 84, was the first pilot during the Second World War to use the Leigh Light, a powerful airborne torch, to illuminate enemy submarines during night attacks.
      In 1941, Greswell had been posted to the Coastal Command Development Unit, where he came into contact with Wing Commander Humphrey de Vere Leigh, who had hunted U-boats in the First World War.
      Greswell was much impressed by Leigh and by the light that he had designed to mount in the gun position of a Wellington. Early trials were successful and in the New Year of 1942, Greswell was selected to command No 1471 Flight based at RAF Chivenor, in north Devon, to introduce the light operationally.
      On the night of June 3-4 1942, Greswell took off from Chivenor in a twin-engine Vickers Wellington bomber of No 172 Squadron. In the Bay of Biscay, he lit up and then depth-charged the Italian submarine Luigi Torelli.
      Greswell's first approach to the Luigi Torelli was frustrated by an incorrect altimeter setting, which meant that his co-pilot, Flying Officer A W R Trigg, was unable to level the beam at the enemy.
      After the altimeter was reset, Greswell took the Wellington to 50ft above the sea and attacked from the starboard beam, dropping two Torpex-filled depth charges either side of the submarine.
      The charges' fuses were supposed to explode at a depth of 25 feet, but they proved defective and the explosions occurred at a greater depth. Even so the submarine's steering gear and compass system were badly damaged, forcing its captain Count Augusto Migliorani to seek refuge in Spanish waters.
      He could not believe his luck when 10 minutes after his attack on the Luigi Torelli, his torch found a second Italian submarine, Morosini. Having already expended his depth charges he went in at 50 feet and attacked with machinegun fire.
      Morosini failed to return from its patrol, but disappointingly for Greswell and his crew, its loss was not ascribed to their attack. As for the Luigi Corelli, though damaged, it ended its war running supplies to the Far East. The Japanese scuttled her in August 1945.
      Though neither submarine had been sunk by his action, Greswell had demonstrated the potential of the Leigh Light and this enabled Air Chief Marshal Sir Philip Joubert, Coastal's commander-in-chief, to obtain early delivery of Leigh Light Wellingtons. Greswell's mission also provided valuable lessons for the future, the most vital being that the attack aircraft's altimeter should always be set correctly.
      For his actions in attacking the two submarines, Greswell was awarded the DFC.
      Jeaffreson Herbert Greswell was born on July 28 1916, at Ashtead, Surrey, and educated at Repton. In 1935 he joined the RAF on a short service commission and in 1937 joined No 217, an anti-submarine squadron.
      After the outbreak of war in 1939, he began flying anti-submarine patrols over the Western Approaches in an operationally obsolescent twin-engine Avro Anson.
      Following his exploit in 1942 over the Bay of Biscay with the Leigh Light, Greswell joined the staff at Coastal Command headquarters. In December he went to the United States to liaise with anti-submarine staff and promote the Leigh Light concept.
      After returning home in the spring of 1943, Greswell served briefly at Coastal's No 19 Group and in June received command of No 179, a Wellington Leigh Light squadron based at Gibraltar.
      The aim of his squadron was to combat the U-boats that were threatening Allied shipping off North Africa and passing through the Straits of Gibraltar. Greswell took part in Operation Swamp which sought to concentrate anti-submarine aircraft wherever a U-boat preyed, and to co-operate with naval anti-submarine vessels.
      In the New Year of 1944 Greswell took part in a typical Swamp sortie. At midnight, he approached U 343, commanded by Oberleutnant Wolfgang Rahn, and released his depth charges at 100 feet.
      His crew observed explosions on the far side of the surfaced U-boat and level with the conning tower. A fellow 179 pilot, Flying Officer W F McDavidson, flew into heavy flak from the U-boat as he was releasing his depth charges, and his Wellington fell blazing into the sea. But Greswell and McDavidson's had between them so damaged the U-boat it was unable to dive. It was subsequently sunk by the naval armed trawler Mull.
      After almost a year with 179, Greswell was posted in April 1944 to Coastal Command headquarters, moving on in July to Coastal's No 18 Group. In July 1945 he returned as a member of the command's air staff.
      There followed a spell in the Far East where in 1946 he liaised with the British Pacific Fleet at Hong Kong and the next year served at Air Command South East Asia (ACSEA) headquarters. As memories of Coastal's contribution receded, Greswell was concerned lest its vital role in defeating the U-boats be forgotten.
      Happily his appointment in 1949 to the staff of the Joint Anti-Submarine School provided an opportunity to press home the mutual benefits of co-operation between the RAF and the Navy.
      Greswell was appointed to the staff of the RAF Flying College, Manby, in 1952. In 1954 he moved to the Ministry of Defence as the RAF representative on the joint planning staff team which drew up plans for the 1956 Suez operation.
      Greswell later maintained that these papers had been disregarded by the politicians, with the result that the Navy was denied the tactical air cover it needed.
      From 1957 to 1959, Greswell was station commander at RAF Kinloss. Later he was standing group representative on the Nato council in Paris. In the four years before his retirement in 1968 he was commandant of the Royal Observer Corps, steering the volunteer organisation through the shoals of change.
      He was fond of croquet and gardening during his retirement near Ringwood in the New Forest.
      In addition to his DFC, he was awarded a DSO in 1944 and was also Mentioned in Despatches. He was appointed OBE in 1946, CBE in 1962, and CB in 1967.
      He married, in 1939, Gwyneth Hayes, who survives him, with a son and two of their three daughters.
