He envisioned 1,000 bomber raids against German cities where aircraft would fly by a common route to and from their targets, all arriving within a short time to disperse their bombs while overwhelming air defenses and German night fighters.

Novel navigation techniques allowed bombers to fly even in poor weather and when successful, the effect on German cities was devastating, forcing the Germans to divert enormous resources to defend their homeland. This tactic was very effective in damaging German industry, transportation and morale and opened a "second front" in Europe long before the invasion of Normandy.
