In May 1940, the opposing German and Allied forces seemed reasonably well matched. On the ground, the four allied nations had more troops, artillery and tanks. Even in the air, the German advantage in numbers was slight. Yet two months later, the Allied armies had been crushed. The Netherlands, Belgium and France had all surrendered and Britain stood on her own, facing imminent defeat. Subsequent accounts of the campaign have tended to see this outcome as predetermined, with the seeds of defeat sown long before the fighting began. Was it so inevitable? Should the RAF have done more to help the Allied armies? Why was such a small proportion of the RAF's frontline strength committed to the crucial battle on the ground? Could Fighter Command have done more to protect the British and French troops being evacuated from the beaches of Dunkirk? This study looks at the operations flown and takes a fresh look at the fatal decisions made behind the scenes, decisions that unnecessarily condemned RAF aircrews to an unequal struggle and ultimately ensured Allied defeat. What followed became the RAF's finest hour with victory achieved by the narrowest of margins. Or was it, as some now suggest, a victory that was always inevitable? If so, how was the German military juggernaut that had conquered most of Europe so suddenly halted? This study looks at the decisions and mistakes made by both sides. It explains how the British obsession with bomber attacks on cities had led to the development of the wrong type of fighter force and how only a fortuitous sequence of events enabled Fighter Command to prevail. It also looks at how ready the RAF was to deal with an invasion. How much air support could the British Army have expected? Why were hundreds of American combat planes and experienced Polish and Czech pilots left on the sidelines? And when the Blitz began, and Britain finally got the war it was expecting, what did this campaign tell us about the theories on air power that had so dominated pre-war air policy? All these questions and more are answered in Greg Baughen's third book. Baughen describes the furious battles between the RAF and the Luftwaffe and the equally bitter struggle between the Air Ministry and the War Office - and explains how close Britain really came to defeat in the summer of 1940.

On 10 May 1940, the French possessed one of the largest air forces in the world. On paper, it was nearly as strong as the RAF. Six weeks later, France had been defeated. For a struggling French Army desperately looking for air support, the skies seemed empty of friendly planes. In the decades that followed, the debate raged. Were there unused stockpiles of planes? Were French aircraft really so inferior? Baughen examines the myths that surround the French defeat. He explains how at the end of the First World War, the French had possessed the most effective air force in the world, only for the lessons learned to be forgotten. Instead, air policy was guided by radical theories that predicted air power alone would decide future wars. Baughen traces some of the problems back to the very earliest days of French aviation. He describes the mistakes and bad luck that dogged the French efforts to modernise their air force in the twenties and thirties. He examines how decisions made just months before the German attack further weakened the air force. Yet defeat was not inevitable. If better use had been made of the planes that were available, the result might have been different.

The events of 1942 marked a pivotal year in the history of British air power. For more than two decades the theory that long-range bombing could win wars had dominated British defence policy. The vast majority of warplanes ordered for the RAF were designed either to bomb enemy cities or stop the enemy from bombing British cites. Conventional armies and the air forces that supported them were seen as an outmoded way of waging war. During 1941 evidence began to mount that British policy was wrong. It had become clear the RAF's bomber offensive against Germany had, until that point, achieved very little. Meanwhile, the wars raging in Europe, Africa and Asia were being decided not by heavy bombers, but by armies and their supporting tactical air forces. Britain had never had the resources to build a large army as well as a strategic bomber fleet; it had always had to make a choice. Now it seemed the country might have made the wrong choice. For the first time since 1918 Britain began thinking seriously about a different way of fighting wars. Was it too late to change? Was a strategic bombing campaign the only option open to Britain? Could the United Kingdom help its Soviet ally more by invading France as Stalin so vehemently demanded? Could this be done in 1942? Looking further ahead, was it time to begin the development of an entirely new generation of warplanes to support the Army? Should the RAF have specialist ground attack aircraft and air superiority fighters? The answers to these questions, which are all explored here by aviation historian Greg Baughen, would help shape the development of British air power for decades to come.
