UK: Winston Churchill gives a speech in the House of Commons, saying "Never in the field of human conflict was so much owed by so many to so few," referring to the ongoing efforts of the Royal Air Force pilots fighting the Battle of Britain.
WWII poster containing part of the famous line by Winston Churchill
Churchill first used his famous words upon his exit from the Battle of Britain Bunker on August 16, 1940. The sentence would form the basis of his speech to the House of Commons on August 20. He had initially rehearsed to say, "Never in the history of mankind..." but when asked, "What about Jesus and his disciples?" he immediately reworded it to "Never in the field of human conflict..."
This speech was a great inspiration to the embattled United Kingdom during what was probably the most dangerous phase (for Britain) of the entire war.
Note: The men in the poster photo are RAF Bomber Command pilots, not fighter pilots, as is generally assumed to be the "few."
