Fighting the Flying Circus by RICKENBACKER, Eddie

This is the WWI memoirs of Medal of Honor winner, Capt Eddie Rickenbacker. He fought in and eventually became commander of the 94th Hat-in-the-Ring Squadron, which ended the war with the highest number of air victories of any American squadron. The circus mentioned in the title refers to the German squadron commanded by the famous Red Baron, Manfred von Richthofen. (Introduction by Brett W. Downey)
