First wave. Fourth aircraft to attack Möhne Dam. Mine dropped accurately, causing small breach. Aircraft shot down on return flight.
David Taylor Horsfall was born in Bramley, Yorkshire on 16 April 1920. The family moved to Barnsley, and both he and his brother Albert went to Barnsley Grammar School. David joined the RAF in 1936 as a boy entrant at the technical apprentice school at RAF Halton. He served in groundcrew until 1942.
He then took the opportunity to retrain as a flight engineer on heavy bombers, and met up with his future crew at 1660 Conversion Unit at RAF Swinderby in late 1942. Along with colleagues, Lawrence Nichols, Gordon Yeo and Wilfred Ibbotson, Horsfall’s first operation was to the difficult destination of Berlin on 16 January, in a Lancaster piloted by Plt Off V Duxbury. He flew on a second operation to Berlin the following day, with Flg Off H W Southgate as pilot, returning on three engines after one failed on the way home. Melvin Young joined the Conversion Unit later, in early March and took over this new crew there. The full crew were then transferred to 57 Squadron at Scampton on 13 March. On 25 March, they were all reposted to the new 617 Squadron.
The Dams Raid was therefore Horsfall’s third operation, and one that they would all have thought had gone well, until they were caught by a burst of flak at the very last moment of real danger.
David Horsfall had a brother, Albert, who had been killed in 1940 serving as a navigator in 50 Squadron. The Horsfall family therefore share an unwanted sad distinction amongst Dambuster families with the Taerums and the Minchins, in that they all had two sons killed on active air force service during the war.
AJ-A was shot down at the last moment of danger shortly after they had passed over the Dutch coast. David Horsfall’s body was washed ashore on 29 May, along with his skipper. They were buried together in Bergen General Cemetery.
