The 1000 plane raid was as much a propaganda victory as a military one. The RAF had to scrounge up obsolete planes and training crews in flight school to make it 1000 planes. Of course, by the end of the war, 1000 plane raids were commonplace.
Well the beginning of the end or end of the beginning is when the Nazis give up on Russian Front. Yep the RAF is getting stronger and we are mobilizing to join the fight big time. We won for a lot reasons but one was the awesome leadership by Churchill even Roosevelt and Eisenhower Patton Marshall and many others I failed to mention. Allies and US out produced them and we had nobody breaking our factories working 24/7.
