"The Necessity of Chivalry" by C.S. Lewis was "published on the 17th August 1940 during the heat and roar of the Battle of Britain - five days after 'Eagleday' (13 August 1940) – the Nazi Luftwaffe’s operation to destroy the Royal Air Force. It was also just three days before Churchill’s famous “Never was so much owed by so many to so few” speech (20 August 1940) concerning heroic British fighter pilots (some 500+ young fighter pilots had been killed in action up to that point)."
