3 July 1940
Kenley airfield was bombed by the Luftwaffe at 16h43. A single Dornier Do.17Z of II./KG 77 dropped six bombs on the airfield.  The attack did not cause any significant material damage and the German bomber was intercepted and shot down by three Hawker Hurricane of No.32 (RAF) Squadron (Pilot Officer Peter M. Gardner ; Sergeant Edward A. Bayley and William B. Higgins).  The attack did not cause any significant material damage.
It is probably this event that caused ten Hawker Hurricanes from No.615 Squadron to take off between 16h00 and 17h25 hours. However, this interception attempt was unsuccessful. This is the opportunity for Sergeant Derrick W. Halton to make his first operational sortie.
Unfortunately the ORB does not show all the aircraft involved.
