I'm not well read on the BoB, but I got a few things from last night's programme.
The change of use of the Me109E to escorting bombers instead of attacking our fighters was a critical factor. The impression was that the Me109E had the beating of our aircraft, albeit with only ten minutes worth of fuel in the operational area.
The German change from attacking our airfields to bombing towns was not a tactical decision so much as a retaliation ordered by Hitler for our bombing of Berlin.
It was also pointed out the Germans were not really making much progress in destroying RAF fighters, pilots and airfields and that they themselves were running out of pilots, aircraft and energy.
They would have been better off sticking to attacking our maritime activity using aircraft, submarines (and mines).
The Germans lost the BoB more than we won it.
Are these fair points?
