Tees took part in Operation Chastise, the famous "Dam Busters" raid on 16–17 May 1943. Sergeant Tees, who was 20 years old at the time of the raid, was the rear gunner in Lancaster AJ-C, piloted by Pilot Officer Warner Ottley, in the third and final wave of aircraft from No. 617 Squadron to leave from RAF Scampton. AJ-C never made it to its target and was shot down near Hamm. Tees should have been the nose gunner but had changed places with Sergeant Harry Strange in the rear turret. Had he not done so Tees would have been killed as the aircraft was picked out by enemy spotlights and hit with antiaircraft fire[5] Tees later recalled that as the aircraft began to rapidly descend, Pilot Officer Ottley said over the intercom "I'm sorry boys, they got us".[6] The aircraft then crashed.
Tees managed to escape from the rear turret and was found unconscious and badly burnt on the ground and was taken prisoner of war.[5] He was the sole survivor from the crew of seven. He required extensive treatment and was imprisoned at Heydekruge POW Camp L6 for most of the war.[4][7][8]
Later life
In 1967 he took part in the Dam Busters reunion held on the 24th anniversary of the raid at Scampton in Lincolnshire.[9]
Later in life Tees lived at 12 Wilbury Hills Road Caravan Site and ran a gentlemen's barber shop in Station Road in Letchworth, Hertfordshire. He committed suicide on 15 March 1982.[10]
