There was no clear-cut moment of victory for the British. They really won when Sea Lion was called off, but this Hitler backdown was a secret. The Luftwaffe kept up heavy night raids on the cities, and this with the U-boat sinkings made the outlook for England darker and darker until Hitler attacked the Soviet Union. But the Luftwaffe never recovered from the Battle of Britain. This was one reason why the Germans failed to take Moscow in 1941. The blitzkrieg ran out of blitz in Russia because it had dropped too much of it on the fields of Kent and Surrey, and in the streets of London.—V.H.
