It is important to note the state of Britain during those dark days. Heros and success were tantamount to keeping moral high, and a American ear open. The Battle of Britain achieved this single-handedly.The RAF Fighter Command, under Lord Dowding achieved a very true victory over a Luftwaffe that had become used to attacking in overwhelming odds.Whether if the Germans had achieved air-superiority they could have invaded the UK is neither here nor there. The Germans no longer had the ability to shock and awe!So although slightly flawed, in my opinion, this book is an extremely valuable read that takes a broader view of the slowing of Hitler's war machine.
