Something I never really understood is why the Germans didn’t do small attacks on radar stations across the channel. Prime target that could be easily gotten to. Hell, they landed a dozen or so guys in America, why not cross the English Channel and knock out England’s eyes when it really counted.
I think that Germany actually did attack some of the Chain Home radar stations, but didn’t persist in doing so. Partly it was because Goering kept flip-flopping on the focus of his air campaign against Britain (another example being his switch to London as a target, at the moment when his strategy of attacking Fighter Command’s airfields was bringing the RAF to the breaking point). And partly it was because Germany didn’t seem to grasp how much the efficiency of Britain’s air defenses depended on the centralized control of air operations based on the information provided by the radar stations.
