The 15th of September 1940.
The Luftwaffe launches its largest air raid of the Battle of Britain.
This day is forever known as Battle of Britain Day.
A day of remembering those few men who fought, on behalf of the many.
The gratitude of every home in our Island, in our Empire, and indeed throughout the world, except in the abodes of the guilty, goes out to the British airmen who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of the world war by their prowess and by their devotion. Never in the field of human conflict was so much owed by so many to so few.
— W. Churchill, Prime Minister of Great Britain
