Military career

On 11 February 1943, Dhenin was commissioned into the Medical Branch of the Royal Air Force Volunteer Reserve as a flying officer (emergency).^[5] He was then appointed the medical officer of No. 166 Squadron RAF, an Avro Lancaster bomber squadron that was based at RAF Kirmington.^[1][6] During his time at Kirmington, he was awarded the George Medal for a rescuing an airman from a burning wreck in October 1943.^[2][7] On 8 June 1944, two days after D-Day, he transferred to a mobile field hospital.^[2][6] Based in Normandy, France, he was tasked with evacuating casualties by air from the campaign across North-West Europe.^[1][3]

Honours

On 14 January 1944, Dhenin was awarded the George Medal (GM), the second highest civil decoration of the UK, for rescuing an airman from a crashed and burning bomber.^[7] In the 1954 New Year Honours, he was awarded an Air Force Cross (AFC) for flying a plane into the mushroom cloud of the first British nuclear bomb test in Australia in 1953.^[10][2] In the 1959 Queen's Birthday Honours, he was awarded a bar to his Air Force Cross (i.e. he was awarded the AFC for a second time).^[11] In November 1974, he was appointed a Commander of the Order of St John (CStJ).^[12] In the 1975 New Year Honours, he was knighted as a Knight Commander of the Order of the British Empire (KBE).^[13]

One night in October, 1943, an aircraft, which had sustained damage during an attack against Hanover, crashed near an airfield. The aircraft disintegrated on impact and immediately burst into flames. The rear gunner was injured and trapped in his crushed turret, being pinned down by the remains of the tail unit and the rear of the fuselage. A high explosive bomb was in the blazing wreckage some 10 yards away from the gunner. Flying Officer Dhenin, the station medical officer, and Corporal Lush, a gunner, hastened to the scene of the accident. Although fully aware that the heat might cause the bomb to detonate at any moment Flying Officer Dhenin worked for over half an hour to relieve the injured airman's pain and, assisted by Corporal Lush, endeavoured to release him. Their efforts to extricate the gunner were, however, unavailing. A mobile crane was brought to the scene and the mass of wreckage was lifted clear of the ground. Displaying complete disregard for his own safety, Flying Officer Dhenin then crawled under the wreckage and released the trapped airman thereby enabling others helpers to drag him to safety. Flying Officer Dhenin and Corporal Lush showed fine courage and determination in circumstances of great danger.
