This is Paul Richey's personal account of the part played by the Royal Air Force's premier fighter squadron in the air battles preceeding the fall of France in 1940. Faced with overwhelming odds, Richey and his comrades at first accorded the enemy mercy and respect, but this attitude was to change once the Luftwaffe began its attacks on helpless refugees.By the time No. 1 Squadron withdrew from France on 18th June 1940, they had gained a formidable combat reputation. Miraculously, they had destroyed a total of 155 enemy aircraft with only three of their own pilots having been killed, two wounded and one captured.
