The 13 Group HQ was at Kenton, near Newcastle upon Tyne with the Filter Room at nearby Blakelaw Quarry.

13 Group also contributed to pilot education by producing its "Forget-Me-Nots for Fighters" brochure, that included a foreword by Air Vice-Marshal R. E.

13 Group had been sending them down their available aircraft), so they had thought that any attacks made on Scotland would not face any serious resistance.

This proved to be a costly mistake for the Luftwaffe, as their bombers were intercepted by a large number of fighters.

The bombers could not be escorted all the way to Scotland from Occupied Europe because of the short range of the Messerschmitt Bf 109 fighter aircraft, so the attacking bombers proved to be fodder for Saul's Supermarine Spitfire and Hawker Hurricane fighter squadrons.

North East England was attacked by 65 Heinkel He 111 bombers, escorted by 34 Messerschmitt Bf 110 heavy fighters, and RAF Driffield was attacked by 50 unescorted Junkers Ju 88 multirole combat aircraft.

New pilots would usually find themselves posted to a 13 Group squadron initially so as to gain experience with lesser risk of getting shot down.

32 Wing of RAF Army Cooperation Command was transferred to 13 Group, and so brought with it three further airfields to operate from; Macmerry, Kirknewton and Findo Gask.
