Before dawn, British bombers attacked railway yards at Hanover, Germany. After sundown, 78 British bombers, escorted by 485 fighters, conducted the heaviest daylight attack against Germany to date, targeting the powerplants near Köln (Fortuna Power Station in Knapsack and Goldenburg Power Station in Quadrath) and other targets in a wide area. The Germans were only able to scramble few fighters, but anti-aircraft fire was heavy. The Germans suffered four fighters shot down (plus five likely shot down) and heavy damage to both powerplants; the British suffered 12 British Blenheim bombers shot down and 10 British fighters shot down.
