According to official documents "Battle of Britain" was the intensive preparations to defence and combat of Royal Air Force against Luftwaffe since September 10 till October 31, 1940. Main effort during this fight was taken by RAF Fighter Command. Contribution of fighter pilots to defence of Great Britain is the best illustrated by Sir Winston Churchill words: “Never in the field of human conflict was so much owed by so many to so few". We Polish, living in United Europe 65 years after "Battle of Britain", are very proud of that among “so few" were also ours compatriots – pilots of two Polish fighter squadrons and detached to RAF units.
