The last act of major resistance by NJG 2 was Operation Gisela. Crews of NJG 3 and NJG 2 were called to a briefing on Gisela under guard. The crews were told that all available night fighters would participate in an all-out attack against Bomber Command over their airfields in England. The tactical deployment for the operation, they were told, was for two waves of night fighters to cross the coast in the region of Hull. To avoid enemy radar raiders were told to fly at minimum altitude and then climb to as they reached the coast, generally believed to be the average operating height of British bombers. The Luftwaffe Western Front Intelligence Summary Service prepared dossiers for crews to study. It advised on the layout of British airfields and the lighting systems, such as the Drem system, along with funnel lights and angle of glide indicators. Crews were warned about RAF lighting codes on the control towers which warned RAF bomber crews of a possible intruder in the vicinity. NJG 2 claimed eight bombers, claimed by five different pilots.
