Question, though. I had always read or seen that the RAF was on the ropes during the Battle of Britain and was almost completely destroyed, right when the Blitz began and the bombing focussed on London, instead of the continuing attacks on airfields and such.
Changing to bombing London saved the RAF, allowing them to rebuild and finally defeat the bombing campaign.
Is this wrong?
Basically, yes that's wrong.
The idea that the RAF came close to defeat is very dramatic and the concept of the "narrow margin" has more to do with dramatisation and common misconceptions than reality. The simple fact is that both RAF pilot and aircraft numbers were not reduced during the Battle of Britain. This was partly due to the success of Beaverbrook in his first months as Minister of Aircraft Production. He inherited a favourable upward swing, but his ruthless improvisation considerably fortified this. The so-called Harrogate Programme of January 1940 provided for a year’s output of 3,602 fighters (very precise). The total achieved was 4,283, which meant that nearly 352 fighters a month were forthcoming over the crucial summer and autumn months. The German output during the same period was barely half that.
One example of this kind of dramatisation can be seen in the description of events of Sunday 15th August 1940, the most intense day in the Battle, Churchill drove from Chequers to visit Air Vice-Marshal Park at Fighter Command HQ where he controlled the fighter squadrons covering the whole of Essex, Kent, Sussex and Hampshire. As they watched the lights on the key indicator boards it became apparent that there were no longer any reserve squadrons left on the board, and Churchill asked Park, "What other reserves have we?" "There are none," Park answered.
That often quoted exchange is used to create the feeling of a closely fought battle with drama worthy of Hollywood. It may have been true that there were no local reserves, or none that could be available in time to effect that days raids, but that's all. At no time during the Battle were the RAF ever close to defeat, they were not depleted in either aircraft, pilots or moral. However, when you take quotes like the one above, and include with them the fears and reservations quoted from other famous participants it is possible to paint a picture of a close call, or a narrow margin, a victory snatched from the jaws of defeat... but facts don't support that picture, and I suspect it probably has more to do with book sales than real history
