MINELAYING
207 aircraft - 68 Lancasters, 60 Halifaxes, 47 Wellingtons, 32 Stirlings - carried out another large minelaying operation. 167 aircraft laid 593 mines off Heligoland, in the River Elbe and in the Great and Little Belts. Low cloud over the German and Danish coasts forced the minelayers to fly low in order to establish their positions before laying their mines and much German light Flak activity was seen. 22 aircraft - 7 Lancasters, 7 Stirlings, 6 Wellingtons, 2 Halifaxes - were lost. This was the heaviest loss of aircraft while minelaying in the war, but the number of mines laid was the highest in one night.
6 Mosquitoes carried out a raid to Wilhelmshaven, dropping many flares to divert attention from that part of the minelaying force which was operating near by. No Mosquitoes lost.
