I'm trying to gather as much information as I can about this Lancaster R5679 shot down on the night of the 25th September 1942 whilst on a Gardening mission to lay mines in the 'Sweet peas' area off the north coast of Germany the air craft was returning when it was attacked by a night fighter over Denmark 2 pilots have been credited as shooting it down Ob Lt Willi Elstermann 11/NJG3 and Ltn Karl Heinz Brandes 7/NJG 2 I believe there is also some reference to it in Theo Boiten - "German Nightfighter War Diaries".

Does anyone out there have access to the German accounts for this action. Next year there are plans for a memorial to be erected in the town Gronhoj where the plane crashed I would like to gather as much information as I can. I have photographs of most of the crew but I am missing Sgt Cedric Nils Coldicott aged 22 service number 570285 RAF and Sgt Edmund Dyson aged 20 service number 1059428 RAFVR. Thanks
