This is a very comprehensive review of the Battle of Britain, the campaign which saved Europe from an indefinite period of darkness, oppression, and inhumanity. Without the courage and resilience of the British people and the courage, competence, and sacrifice of the young pilots and crews of the RAF from whom so much was demanded Hitler's legions would have stood triumphant over a defeated Europe. The level of detail about the technological and tactical development of aerial combat and strategic bombing from WWI to WWII, including radar, propellers, engines, gasoline, machine guns, gunsights, will attract aviation 'wonks' and the address of the broader political imperatives which led to war will attract the historian and political scientist. Mr. Jacobs' unbelievable sketches throughout add very helpful imagery of the aircraft which fought the campaign. I was intrigued, too, by the description of the influence of American aviation developments in the building of the German and British airfleets. I wish, though, the authors had addressed in more detail the effect of the early British breaking of German communication codes. A good read!
