Brilliant as Dowding and Park were they nearly lost when the LW concentrated on raids against Radar and Airfields. PArk was able to strip away the escorts when the objective, London, was clear. The Me109 had fuel to fight over London for, 5 minutes Park only had to make the escorts use burn 5 minutes of fuel and he would eventualy have the bombers alone regardless of the ratio. During the BoB Germany came no where near replacing their material losses while the RAF was replacing losses of aircraft although pilots were another matter. In 1944 Germany was struggling to provide pilots planes and fuel, even starting with 2000 planes and pilots they would lose because the allies had more and could more easily replace them.
I think Bungey (His book "Most Dangerous Enemy") pretty much has debunked that common mythology. Only one airfield (Manston) was ever put out of operation. Virtually no planes were caught on the ground. The radars were hard to take out, only a Stuka might do it and they were easy prey, and the RAF had redundancy and mobile radars and quick repairs. The Luftwaffe tried that for weeks and got nowhere, except large losses.
The Germans attacking London was a last resort because nothing else had worked, the RAF just kept inflicting unacceptable losses. The Germans had worse problems getting new pilots and they didn't have the production of the British to replace machine losses.
Only if they had hit Sector stations and took out the controllers could they have done it...and they didn't know they existed, their importance or where they were.
They needed a quick victory (to enable an invasion), so they depended on the RAF being stupid. That is put up all their fighters in the air so that the Luftwaffe experten could shoot them down at a 5:1 ratio (as if) or get their planes caught on the ground. Neither of these things happened, Park tactically managed his forces beautifully.
Oh yes the RAF was under pressure all right, but so was the Luftwaffe. Neither side really knew how the other one was suffering. The Luftwaffe fell prey to over confidence, the RAF, correctly, remained very conservative. Even at the worst point, when Dowding broke up squadrons (allocated as A, B C categories) Fighter Command actually had more pilots than at the beginning of the Battle (don't forget the huge losses they suffered in France which had to made good). They were under
establishment (ie theoretical) strength, but they still had plenty...plus reserves, which the Luftwaffe didn't.
And the Luftwaffe newbies were just as bad as the RAF ones, ie cannon fodder.
So the BoB would still have turned out the way it did, even if the Luftwaffe had kept on at the airfields (etc) and never touched London.
The Luftwaffe were not stupid they also tried very hard to take out aircraft production...and like Bomber Command and the USAAF did later, failed, despite the fact that (at that time) the Supermarine and Hawker production were well within 109 escort range (closer than London).
So we are back to inaccurate bombing again, which had little effect, so the bombers were just the reason to get the RAF up so they could be shot down. Trouble was, FC (after France) had a hard core of experienced pilots ..and, which they could never understand (and didn't understand later in '43 and '44) the concept of a 'General' maintaining effective tactical control over his forces.
You have to remember the Heer (Army part of the Wehrmacht) training, leadership, doctrine, etc (such as Mission Command) was all worked out before the Nazis took over. It was a master of 3rd Generation warfare. Hence why it was so good.. and took the combined forces of the USSR, UK and US to beat them.
The Luftwaffe was created by the Nazis. Hence it's doctrine and ethos were very different. Full of the 'warrior hero' nonsense. Technology, logistics, tactics, were secondary to 'will power' and all that piffle. Hence things like Galland not wanting radios in fighters in the BoB, pilots never getting breaks (while their soldier brothers were far better looked after). Marseille feted, who slaughtered huge numbers of Hurricanes and P-40s...and shot down only 4 bombers in his entire career (leaving his soldier brothers to get hammered by the DAF while he got the headlines...dickhead).
Galland, even at the end, still couldn't except tight effective tactical ground control. To him the pilots in the air were the 'kings'...and then repeated the mistakes of Leigh Mallory in France in '41...the same which mistakes he benefited from in getting his 'score' (and medals).
So it was a weird and very disfunctional organisation, the most effective leader of it all was Kesselring, a very (prior and later) good ground general..who got thumped twice by Park.
Park was like Monty, a really good General who knew his stuff inside out. He knew what he wanted to achieve, he learned, he taught, he changed things. He out thought the enemy at all points...he denied them of what they wanted. He never risked too much at any point in time, hence his opposition to (along with many other reasons) the 'big wing stuff. He understood that air warfare was 3 dimensional and that timing, position and surprise were more important than just raw numbers. 4 planes at the right time and place with the advantage of position and surprise can create more damage than 200 at a tactical disadvantage.
And he cared about his pilots. When the Luftwaffe was hitting the RAF's airfields (many not Fighter Command) his jumped up and down, not because the airfield's were out of operation ..they weren't (Spits and Hurris all took of in grass) but because the pilots didn't have a bed and food and so on. Unlike Leigh Mallory, Park got in his Hurricane and went all round his airfields and talked to his people regularly.
A true leader.
The Luftwaffe, unlike the Heer who produced many of them, was incapable of producing and using people like Park...hence they lost.
Though the RAF (overall) wasn't much better in may ways since it fired Park and Dowding real fast after the BoB.....took until the DAF to get it back being useful again.... 70% losses in Bomber Command (50% killed)? Which was the same the Luftwaffe overall suffered, as did the U-Boats.... Ideology (idiotology?) achieves nothing just gets people killed for nothing.
