Night fighters claimed two aircraft, a Hampden AT156 EA-C from 49 Squadron flown by F/O. Kay D.F.M. who was made a P.o.W., 2 other crew members killed and the fourth evading capture.
Oblt. Heinrich Peterson (2) from 6./NJG1, his first abschuss shot X9764 down at 02.28 hrs over Geetbetz – all the crew were killed.

(1) F/O. Ludwig Karol Assman survived an earlier incident whilst flying on Wellington IC W5720 NZ-Q. Hit by flak, ditched some 30 miles off cromer and rescued after spending some 17 hours in a dingy by the Sheringham lifeboat, ‘Foresters Centenary’.
(2) Understood to have survived the war despite being wounded on the 6/6th June 1942 after a collision with a 149 Squadron Stirling R9314. All but one of the crew managed to survive after ditching in the Channel. The rear gunner, 21 year old Sgt. Keith Roderick from Glamorgan, Wales, was killed when the Me110 hit his turret. The Me110 crew baled out.
