cloud of small, thin pieces of aluminium which effectively made it impossible for the German radar operator to identify the genuine target. Saturation of the Himmelbett control areas by a bomber stream and the introduction of Window practically made the previous Himmelbett procedure obsolete. This was also evident to the German high command. To counter these British measures two new strategies were pursued, Wilde Sau (Wild Boar) and Zahme Sau (Tame Boar). Wilde Sau, conceived by Hans-Joachim Herrmann, was a technique by which the RAF bombers were mainly engaged by single-seat fighter planes, illuminated by searchlights, over the target area. The Zahme Sau procedure, proposed by Viktor von Loßberg, called for a night fighter to infiltrate the bomber stream. The position, altitude, and general direction was then broadcast. The information was received by other night fighters, who navigated to the bomber stream by themselves. In Zahme Sau, the German night fighters were tracked and radio-controlled by means of Y-Verfahren (Y-Control). Schnaufer did not make any claims during Operation Gomorrah. Their next success came when he and Freymann shot down a Lancaster on 10/11 August 1943 at 00:32. The target that night was Nuremberg and it was the first aerial victory of the entire German night fighter force achieved by Y-Control. This was also the last victory with Freymann and his last as a member of II. Gruppe. Squadron leader of 12.Staffel/NJG 1 Schnaufer was transferred to IV Gruppe of NJG 1 (IV./NJG 1—4th group of the 1st Night Fighter Wing), based in the Netherlands at Leeuwarden Air Base, where he was appointed Staffelkapitän (squadron leader) of the 12. Staffel (12./NJG 1—12th squadron of 1st Night Fighter Wing) on 13 August 1943. He took over command from Oberleutnant Eberhard Gardiewski, who had been taken prisoner of war. At the time, IV./NJG 1 was under the leadership of Gruppenkommandeur (Group Commander) Hauptmann Hans-Joachim Jabs. Jabs' first impression of Schnaufer was not entirely favourable. Shortly after Schnaufer's arrival, on one of his first missions in Leeuwarden, Schnaufer had taken right of way during taxiing. This forced Jabs into second place in order of takeoff, an act of insubordination and perceived as arrogant by Jabs. Schnaufer, who had received the German Cross in Gold () on 16 August 1943, flew his first operational mission with 12./NJG 1 on the night of 17/18 August 1943. Although uncertain, it is assumed that Handke was Schnaufer's radio
