This fairly short book was first published in 1990 for the fiftieth anniversary and has now been reissued for the seventy-fifth. It recounts in clear style the events of 15 September 1940, truly one of the great turning point days in British history. The various airborne attacks and skirmishes are well portrayed, with many eyewitness accounts incorporated. The popular image that it consisted of numerous, lengthy dogfights is not in fact the case as the skirmishes were almost all very fast and furious. The book also goes onto establish as accurate a picture as can reasonably be arrived at of the total losses of planes on either side (56 on the German side, and about half that number on the British side). Aside from these data (and more German planes were destroyed on some earlier days in the summer airborne fighting), the book clearly positions the events of that day as the decisive ones which prompted Hitler to postpone the invasion of England indefinitely two days later, having realised that the RAF was not the busted flush that he thought. It may be a truism, but is nevertheless worth remembering what we owe today to the RAF pilots' successes in the air on that day 75 years ago. ( )
