Re: Will you kindly stop with the "Britain alone" myth?
True, but in summer 1940 the Common Wealth wasn't about to come under heavy air attack or stood waiting for a seaborne invasion.
At that critical moment, everything hinged on the island holding out and critically the very moment hung on what Downding described as "Our young men will have to shoot down their young men at the rate of five to one."
The power of the Empire would come to play later and ultimate wartime victory in Europe was only possible because of the weight, plus of course the industrial might of the USA and the sheer military muscle of the USSR.
Allied victory is what was achieved, not British, not British Empire, not USA, not Soviet.
