The battles that were waged in Flanders during the First World War were some of the most costly of the war. All sides paid a very high price for what only ever amounted to temporary control of the area. One thing that has never been in doubt is the courage and valour that was displayed on these battlefields, not only by the men on the ground, but also by the airmen who waged their own battles above the sodden fields of Flanders. This book related the five years of fierce battle in the air above the Ypres Salient. Written from a German standpoint, this book gives a detailed account of the growing airpower of the German Air Service and the Naval Air Arm.
