The first illustrated study in English of the Finnish Air Force's battle to repel the Soviet invaders during the Winter War, one of the greatest David-and-Goliath air battles in history.

In 1939, the Soviet Union invaded its neighbour Finland, sparking the Winter War. While Finland was heavily outnumbered in all respects, in few respects was the contest so uneven as in the air. In this book, veteran Finnish aviation historian Kari Stenman draws on his decades of research to present the first account in English of the Finnish Air Force's defence of the country's skies, a clash that pitted its 114 combat aircraft against the Soviets' 2,318.

He explains that, equipped initially with a handful of British and Dutch aircraft, Finland's air force adopted similar guerrilla tactics to its infantry. Fokker D.XXI interceptors were scattered to remote landing grounds to ambush the Soviets and give an impression of strength, while the bombers were first used for long-range reconnaissance and harassment. Over the course of the war, the Finns received new Gladiators, Fiat G.50s and French MS.406s, until at the close of the war, all flying units were thrown in to repel the Russian invasion across the frozen Gulf of Finland.

Illustrated with previously unpublished photos, superb original artwork, 3D diagrams and maps, this reveals for the first time the full story of how Finnish aviators fought for their country's independence.
