Includes 29 Illustrations The advent of an American squadron, or “escadrille,” within the French air force, the Service Aeronautique, had been far from a simple process. French leaders initially held the belief, common at the time, that the war begun in 1914 would be a short one. The potential value of American volunteers fighting for France both for propaganda purposes and for helping bring the power of the New World into the war on the side of the Allies was thus irrelevant at first. By early 1915, however, the French began to accept American volunteers and assign them to escadrilles. In early 1916, the Service Aeronautique united several of these men in an elite chasse unit, which quickly earned an enviable reputation for audacity, bravery, and élan. Success of this unit, the Lafayette Escadrille, had three consequences. First, its existence encouraged a large number of Americans, far more than needed in one escadrille, to volunteer for French aviation. These individuals, identified unofficially as members of a “Lafayette Flying Corps,” served in numerous French air units. Second, the publicity surrounding the Lafayette Escadrille contributed favorable press for the Allied cause, strengthened ties between France and the U.S., and ultimately helped prepare the U.S. to participate on the Allied side of the conflict. Third, the existence of a large body of experienced American pilots provided combat veterans for the Air Service of the American Expeditionary Forces (AEF) in France when the U.S. ultimately entered the war. These veterans helped instill in the U.S. Air Service the attitudes and practices of the Service Aeronautique, an infusion especially reflected in two U.S. pursuit squadrons, the 103rd Aero Squadron, made up of Lafayette Escadrille pilots, and the 94th Aero Squadron, the most famous American combat squadron of the war.

On the morning of May 18, 1916, a German LVG appeared in the sky over Thann in the Vosges region, near the ancient French city of Nancy. The LVG was a well-armed, two-seat observation airplane and the Vosges a quiet sector of the Western Front, in stark contrast to the merciless slaughter taking place to the north at Verdun. Normally the two airmen could expect to do their reconnaissance with little interruption, but on this day they had left luck behind. A speck appeared in the sky to the west and rapidly grew into an enemy pursuit aircraft, an avion de chasse, an agile, single-seat Nieuport. The Germans, busy at their trade, failed to see the enemy draw near. A veteran hunter or more cautious pilot might have seized the opportunity to surprise the LVG and launch an attack out of the sun or from behind a cloud, but this one approached directly, without guile. Suddenly aware of the danger, the observer seized his machine gun and began firing while the pilot turned the airplane toward the safety of the German lines. The chasse pilot closed to point blank range and, just as a collision appeared imminent, fired a quick burst, then swerved away. The encounter was over that quickly. Both the observer and pilot collapsed; the LVG rolled and plunged to earth; the Nieuport banked away leaving a plume of smoke to mark the scene of combat. French troops witnessed the brief fight and by the time the Nieuport reached its field at Luxeuil-les-Bains had confirmed the kill. It was an auspicious event. Everything about the victorious aircraft said "France" except the pilot's name. Kiffen Yates Rockwell was an American citizen assigned to Escadrille N 124, known unofficially as l'Escadrille Americaine, and his victory was the unit's first. It was quick and impressive by contemporary standards of air combat. Rockwell had engaged at incredibly close range, almost sticking his gun into the enemy cockpit, but his daring attack allowed the LVG's observer to put a hole in the Nieuport's top wing main spar. Rockwell, in turn, killed the two men with only four bullets, a marvelous feat of marksmanship. Cheering comrades lifted him from the cockpit and began a wild celebration. Atradition began with N 124's first victory. Rockwell's brother Paul, serving elsewhere in the French Army, provided a bottle of eighty-year-old bourbon. Kiffen Rockwell took the first drink, but the Escadrille set aside the rest. From then on, credit for downing an enemy aircraft earned the victorious pilot a shot from "The Bottle of Death."

Except in a few instances, since World War II no American soldier or sailor has been attacked by enemy air power. Conversely, no enemy soldier orsailor has acted in combat without being attacked or at least threatened by American air power. Aviators have brought the air weapon to bear against enemies while denying them the same prerogative. This is the legacy of the U.S. AirForce, purchased at great cost in both human and material resources.More often than not, aerial pioneers had to fight technological ignorance, bureaucratic opposition, public apathy, and disagreement over purpose.Every step in the evolution of air power led into new and untrodden territory, driven by humanitarian impulses; by the search for higher, faster, and farther flight; or by the conviction that the air way was the best way. Warriors have always coveted the high ground. If technology permitted them to reach it, men, women andan air force held and exploited it-from Thomas Selfridge, first among so many who gave that "last full measure of devotion"; to Women's Airforce Service Pilot Ann Baumgartner, who broke social barriers to become the first Americanwoman to pilot a jet; to Benjamin Davis, who broke racial barriers to become the first African American to command a flying group; to Chuck Yeager, a one-time non-commissioned flight officer who was the first to exceed the speed of sound; to John Levitow, who earned the Medal of Honor by throwing himself over a live flare to save his gunship crew; to John Warden, who began a revolution in air power thought and strategy that was put to spectacular use in the Gulf War.Industrialization has brought total war and air power has brought the means to overfly an enemy's defenses and attack its sources of power directly. Americans have perceived air power from the start as a more efficient means of waging war and as a symbol of the nation's commitment to technology to master challenges, minimize casualties, and defeat adversaries.

The author examines fully the military role of chemical warfare and its effects on the people, industries, and administrations on both sides; he also considers the growing moral problems it created. The launching of an entirely new weapon that did not discriminate between soldiers and civilians raised complex issues which were debated endlessly between the wars and which, in recent years, have led to agreement among the powers not to use chemical or biological warfare.
