Oswald Boelcke was Germany's first ace in World War One with a total of forty victories. His character, inspirational leadership, organizational genius, development of air-to-air tactics and impact on aerial doctrine are all reasons why Boelcke remains an important figure in the history of air warfare. Paving the way for modern air forces across the world with his pioneering tactics, Boelcke had a dramatic effect on his contemporaries. The fact that he was the Red Barons mentor, instructor, squadron commander and friend demonstrates the influence he had upon the German air force. He was one of the first pilots to be awarded the famous Pour le Mrite commonly recognized as the Blue Max. All of this was achieved after overcoming medical obstacles in his childhood and later life with a willpower and determination. Boelcke even gained the admiration of his enemies. After his tragic death in a midair collision, the Royal Flying Corps dropped a wreath on his funeral, and several of his victims sent another wreath from their German prison camp. His name and legacy of leadership and inspiration live on, as seen in the Luftwaffes designation of the Tactical Air Force Wing 31 Boelcke. In this definitive biography RG Head explores why Oswald Boelcke deserves consideration as the most important fighter pilot of the 20th century and beyond; but also for setting the standard in military aviation flying. This book will appeal to enthusiasts of the German air force, military aviation in general and World War One in particular.
