Polish Aces of World War 2 [PDF ebook] 

Illustrated throughout, this book describes the action pilots of the Polish Air Force saw from the first day of World War 2 until the final victory in Europe.Flying hopelessly outmoded P.11 fighters in defence of their country in September 1939, a handful of aviators inflicted serious losses on the Luftwaffe before being overwhelmed. The survivors escaped to then neutral Hungary and Romania, before being ordered to France by the new C-in-C of exiled Polish Armed Forces, General Sikorski.As this book describes, with the invasion of Western Europe in May 1940, the surviving pilots were once more thrust into desperate action in newly-formed Polish units
