In the early hours of 4th April [but see comments below] a black painted Hurricane night fighter from No. 87 Squadron flying from RAF Charmy Down, Somerset was patrolling in the dark watching for the frequent German raiders targeting the ports of South Wales and Bristol. With no technical aids and reliant only on his eyes, the pilot of the Hurricane found a twin engine bomber heading south at 10,000 feet. It was headed in the direction of German bombers returning to bases in France.
The pilot stalked the returning German raider for several minutes unseen before opening fire and watching the bomber spin out of control to crash near the market town of Sturminster Newton in Dorset. Four crew members were able to escape by parachute, but the rear gunner was later found dead in the wreckage.
The tragedy was that the rear gunner was Sgt William Brindley of the RAF. The Hurricane night fighter had shot down a Whitley bomber from No. 51 Squadron, on course for the the Nazi battle cruisers at Brest. Sergeant Brindley now lies in the cemetery near RAF Dishforth, his home base.
This was but one incident of ‘friendly-fire’. How common such events were is hard to assess, as no publicity was given to them at the time and RAF records remain opaque.
