Kammhuber started looking for solutions, and the result was the two-prong concept of "Wilde Sau" ("wild boar") and "Zahme Sau" ("tame boar"). In the former, day fighters would be sent up and look for the enemy aircraft from the light of flares dropped from light bombers, searchlights set to a wide beam or illuminating lower clouds, or the fires on the ground below. The "Wilde Sau" force scored their most notable success during Operation Hydra (the British operation against the V-weapon centre), at Peenemünde on 17 August 1943. De Havilland Mosquito bombers had dropped target marker flares over Berlin and most of the night fighter force was sent there. When it was realized what was really happening, most of these aircraft were too far away and too slow to intercept the raid. However, the Focke-Wulf Fw 190s being flown by the "Wilde Sau" forces were able to reach them, and about 30 planes entered the third and last wave of the stream and shot down 29 of the 40 Avro Lancaster bombers lost on that raid.
