In August 1943, I and II/NJG 2 were deployed to the 4 "Jagddivision" covering Eastern Germany including Berlin, and the Baltic coast. The return of units from the Mediterranean left only one "gruppe" fit for operations while the others resited and replenished. Bomber Command's attack on Peenemünde in August 1943 involved NJG 2 only peripherally. Parts of NJG 2 were at Gilze Rijn but only a single crew from the "Ergänzungsstaffel" reached Peenemunde and claimed a single bomber destroyed. On 15 October 1943, NJG 2 moved to the 1 "Jagddivision" covering the Netherlands and Belgium. I "Gruppe" was positioned at Gilze Rijnen, II "Gruppe" at Melsbroek, and III "Gruppe" was based at Schiphol near Amsterdam. The attack on Kassel on 22/23 October was frustrated by Operation Corona which confused the defences and allowed Bomber Command to devastate the centre of the city. Prominent night fighter teams scored this night. Heinrich Prinz zu Sayn-Wittgenstein and Meurer claimed two and one apiece. 39 Bomber Command aircraft were reported lost; the Luftwaffe lost six night fighters. On 29 November 1943, NJG 2 and the 1st-5th night fighter wings were to reorganise. The plan was for each wing to be equipped with one type of aircraft. For NJG 2, the plan was to convert purely onto the Ju 88R for "Tame Boar" operations only though the goal was only partially realised. In August 1943 the Luftwaffe night fighter arm claimed 250 aircraft shot down on all fronts. The success was offset by losses of 40 killed, with only 28 replacements in August. 61 twin-engine night fighters were lost during the month, 59 were replaced.
