This early work details the history of an American Aero Squadron and their role in the First World War. This is a fascinating read for anyone interested in military aviation and the Great War.

The series forms a commemorative tribute to mark the passing of one of the world's bloodiest wars, offering new perspectives on this tragic yet fascinating period of human history.

Formed in August 1917, The 91st Aero Squadron was a United States Army Air Service unit that fought on the Western Front during World War I. The 91st was one of the first five American flying squadrons to arrive in France, arriving at Chaumont Aerodrome on 15 November 1917. This is a well written unit history, by one or several of the members still serving in Germany after the cessation of hostilities in November 1918. It details the personnel of the unit and a near-daily account of operations/missions and major offensives in France, plus their operations after the war in occupied Germany. It has several photographs taken by the unit themselves (but are very low-resolution unfortunately). It also includes a summary of unit statistics and accomplishments, a personnel list with origin and disposition of Officers and Men of the unit. Students of WW One history and those interested in early flying combat will find this volume to be just as jaunty, interesting and engaging as any similar era unit history of a fighter/pursuit group. It truly gives one a feeling for the trials, tribulations, and tragedies felt by these young American airmen so far from home.

Following the Armistice in 1918, Maj. Gen. Mason M. Patrick, Chief of Air Service, American Expeditionary Forces, directed that a record be made of lessons learned during the war. This information, he believed, was needed for planning the Air Service of the future. The reports prepared by commanders, pilots, observers, and other members of the various Air Service units in response to General Patrick's directive are of considerable historical interest for the information they contain about the Air Service and its employment at the front. A select group of the reports on lessons learned make up Part 1 of this volume of World War I documents on U.S. military aviation. Part II is devoted to a report on the effects of Allied bombing in World War I. This long-forgotten document, the result of a post-war investigation by the Air Intelligence Section of General Headquarters, American Expeditionary Forces, is the counterpart of the well-known United States Strategic Bombing Survey of World War II.
