Britain was an island under siege. The march of the Nazi war machine had been unrelenting. France and Belgium had quickly fallen and now she stood alone to counter this gravest ever threat to her sovereignty in almost a thousand years of history. However, her fate would not be decided by armies of millions but by a unique band of fighter pilots. It was on their shoulders that Britain's only chances of survival rested. Today it seems almost unimaginable. Yet in the summer of 1940 it was all too real. Above the villages and cities, playing fields and market towns, the skies of southern England were the scene of countless dogfights as the fledgling Fighter Command duelled daily against the might of the Luftwaffe. It was an unforgiving test of combat, that measured men and machine ruthlessly. Lavishly illustrated with photographs, contemporary art and posters, and accompanied by numerous first-hand accounts, this is a volume that captures the reality and the romance of a defining chapter in British history.
