 The German controller, who had never heard of Peenemünde, naturally assumed that the inbound main force was also headed for Berlin and marshalled his fighters over the capital.Some 30-35 fighters eventually flew to investigate the distant visible fires at Peenemünde on their own initiative, shooting down 40 bombers at the tail end of the stream, a loss of 6.7% for Bomber Command.This was considered acceptable for such an important target, when the moonlight conditions favoured the defence.
