[Peter Cornwell]

Indeed it is & has been a well-documented & widely-held view for decades - far from being anything new, radical, nor even controversial. The change in focus for German attacks in late August & early September brought 'intense relief' to DOWDING - greater than he could express at the time. 'I could hardly believe that the Germans would have made such a mistake.' PARK was equally relieved, writing within days of the switch in German tactics, 'Had the enemy continued his heavy attacks against Biggin Hill and the adjacent sectors ... the fighter defences of London would have been in a perilous state ...'. The Luftwaffe effectively achieved its goal of air superiority over southern England by the end of August and had it maintained its attacks on Fighter Command airfields for just one more week the outcome might well have been disastrous for Britain. This has all been very well documented over the years & all one needs do is consult the required reading.
