After RAF Bomber Command had established itself with significant numbers of aircraft, it focussed its energies on the industrial sections of Germany. Towns and cities already damaged were hit again; this was because though light industries had been moved, it had been impossible to move heavy engineering and metal works. The raids therefore had substantial impact.

On October 9th, 435 aircraft attacked Bochum.  On that day, 179 Halifaxes from several squadrons, including Squadron 424, set out to join the attack.  The crews were over the target between 17,000 and 20,000 feet, releasing 928,000 pounds of high explosives and 544,000 pounds of incendiaries.  The target was covered by clouds, and according to reports, the attack itself was scattered.

Flight Lieutenant G.A. Bumstead, from Vancouver, was assigned to No. 6 (RCAF) Group, Squadron 424 at that time. On the 9th, he was part of the crew flying Halifax III MZ-802, coded QB-G (with nose art Gallopin’ Gertie) and airborne from Skipton-on-Swale.  The squadron’s commanding officer, W/C G.A. Roy DFC, the pilot, along with his crew, failed to return from their raid.    It was later determined that one crew member was killed and six became POWs.  F/L Bumstead, POW No. 8226, was interned in Camp L3.
