Peter Cornwell tells the story of the greatest air battle of the Second World War when six nations were locked in combat over north-western Europe for a traumatic six weeks in 1940. He describes the day-to-day events as the battle unfolds, and details the losses suffered by all six nations involved: Britain, France, Holland, Belgium, Germany and, rather belatedly, Italy. As far as RAF fighter squadrons in France were concerned, it was an all-Hurricane show, yet it was the Blenheim and Battle crews who suffered the brunt of the casualties. Every aircraft lost or damaged through enemy action while operating in France is listed together with the fate of the crews. The RAF lost more than a thousand aircraft of all types over the Western Front during the six-week battle, the French Air Force 1,400, but Luftwaffe losses were even higher at over 1,800 aircraft.
