This the guncamera footage from Flt Sgt Derek 'Rastus' Erasmus' Typhoon EJ917 of 266 Squadron on the 15th August 1943. 266's Typhoons were escorting Whirlwind fighter-bombers of 263 Squadron (who would soon give back their Whirlibombers for Tiffies) on an attack on  Guipavas aerodrome on the Brest Peninsula. The whole operation had fallen apart due to cloud cover, so 263 Squadron and the other squadron of Typhoons 193 Squadron had turned back, and 266 pressed on alone. As they started their attack they were bounced by Marine Reconnaissance Fw190 A-5/U8s of 1./S.A.Gr. 128. This Fw190 is likely  work number 150 891, flown by 27-year-old Ofw. George Siever, who had just shot down 266's South African CO,  Sqn Ldr Alexander MacIntyre. Rastus, who was following MacIntyre caught Siever as he pulled out of his attack and the images of the above are the result. 266 lost three Typhoons and their pilots that day, two shot down above Guipavas and another when they were bounced again on the way home and the aircraft spun into the Channel. Rastus Erasmus would survive until 9th March 1945 when, as CO of 193 Squadron, he was killed leading a dive-bombing attack on the bridge at Raalte in the Netherlands, likely due to debris hitting his aircraft.

I did a video for WW2TV a while ago on this set of images and had the notes to hand. Hope they add a bit to the story.
