A squadron history strictly based on the unit's diary of operations on the Western Front in the final year of the Great War, and written by the squadron commander. 99 was a bombing squadron, equipped with DH9s, and employed on long-distance raids both on enemy-occupied areas of Alsace-Lorraine in France and inside Germany itself. This factual history gives and unvarnished and detailed account of its raids on such targets as Dillingen and Offenburg railway stations; Hagenau and Buhl aerodromes; Metz and Thionville rail sidings. The volume is particularly distinguished by the great quantity of aerial reconnaissance photos showing the damage inflictied in its raids. As such it should be of great value to all those interested in the development of air bombing.
