For three months in the long hot summer of 1940 the British Royal Air Force and the German Luftwaffe fought an epic battle in the skies over the Southeast of England. Britain seemed unprepared against an undefeated Germany, yet by the end of the summer the Luftwaffe was in retreat. Britain had defended her skies and prevented Germany from carrying out it's plans for an invasion. How did the British do it? Legend says it was down too a few plucky Brits and there fabled Spitfire.
