I'm sure that I'm not the only student of military and aerospace history that has had enough of the usual subjects: B-17s and P-51s of the 8th Air Force, the invasion of Normandy, panzers and their battles, and so on. What this books offers is information about an unusual subject: Finnish fighter aces in World War II.
To most readers, the Finnish-Russian battles are an obscure sideshow to World War II. Yet this was a fascinating theater of the war. Outnumbered and often with obsolescent aircraft, the Finns fought with bravery and skill. Warrant Officer Eino Juutilainen was the top Finnish ace, with 94 victories. This made him one of the top-scoring fighter aces of World War II, with other Finns also having impressive records.
The color plates are the highlight of Osprey publications, and the ones in this book are outstanding. They encompass both the aircraft and their pilots. The photographs are also good. The text is a little dry and there are too many typos. This is a minor point but does detract from the book. The only significant omission in the book is a map. I don't know the geography of Finland, I doubt that most other readers do either, and it is hard to follow the narrative without a map. Given the excellent maps in other books from this publisher, this is a big disappointment.
In summary, a decent book about an interesting and obscure subject.
