Undoubtedly the most famous of any nation’s aviation units in World War 1 was the legendary Jagdgeschwader Nr 1, or ‘The Flying Circus’ as its respectful foes labelled it. Germany’s first true fighter wing, it would always be associated with its first commander, the charismatic and revered Manfred von Richthofen. JG 1 was formed in July 1917, and for sixteen months the unit’s young pilots in their colourful aircraft battled for aerial dominance of the Western Front. From its ranks emerged many of Germany’s most successful airmen, including the Red Baron’s brother Lothar; Ernst Udet; Werner Voss; Erich Löwenhardt and Hermann Göring. This book charts the World War I experiences of JG 1.
