If I could spell it. Yes. It was the initial major air push of the Luftwaffe over Britain that lasted for several months. RUMOR (and nothing else) suggests that the Enigma code machine was fully cracked at this time, but because the British forces did not want to give away the fact that they had this device, they did not order full-scale evacuations of to-be-bombed areas.

RUMOR, but interesting at that. Makes tactical sense.
