From the very beginning of the Great War, the French Air Service possessed dedicated fighter aircraft and units, and like all the air forces of that war, her pilots had to learn from harsh experience the lessons of how to fight in the air and survive. Many did not. Frank Bailey, an acknowledged expert on French aviation during this period, has created as detailed a list as possible covering all the claims and losses of the French fighter force on a day-by-day basis. Unlike their British counterparts, the French did not credit pilots with kills if they could not be confirmed, although they acknowledged probable kills. Confirmed and probable claims are all listed, therefore, along with the escadrille the pilot flew with, and the pilot's running total of confirmed victories. This a companion volume to The Jasta War Chronology (published in 1998), presents detailed information and previousy unpublished photos, and should be of interest to historians and researchers alike.
