Sergeant Bert Hall, who signs from the Lone Star State and had got himself shifted from the Foreign Legion to aviation soon after Thaw, was flying a Nieuport fighting machine, and, a little later, instructing less-advanced students of the air in the Avord Training School. His particular chum in the Foreign Legion, James Bach, who also had become an aviator, had the distressing distinction soon after he reached the front of becoming the first American to fall into the hands of the enemy. Going to the assistance of a companion who had broken down in landing a spy in the German lines, Bach smashed his machine against a tree. Both he and his French comrade were captured, and Bach was twice court-martialed by the Germans on suspicion of being an American franc-tireur--the penalty for which is death! He was acquitted but of course still languishes in a prison camp "somewhere in Germany." The sixth of the original sextet was Adjutant Didier Masson, who did exhibition flying in the States until--Carranza having grown ambitious in Mexico--he turned his talents to spotting los Federales for General Obregon. When the real war broke out, Masson answered the call of his French blood and was soon flying and fighting for the land of his ancestors.

Of the other members of the escadrille Sergeant Givas Lufbery, American citizen and soldier, but dweller in the world at large, was among the earliest to wear the French airman's wings. Exhibition work with a French pilot in the Far East prepared him efficiently for the task of patiently unloading explosives on to German military centres from a slow-moving Voisin which was his first mount. Upon the heels of Lufbery came two more graduates of the Foreign Legion--Kiffin Rockwell, of Asheville, N.C., who had been wounded at Carency; Victor Chapman, of New York, who after recovering from his wounds became an airplane bomb-dropper and so caught the craving to become a pilot. At about this time one Paul Pavelka, whose birthplace was Madison, Conn., and who from the age of fifteen had sailed the seven seas, managed to slip out of the Foreign Legion into aviation and joined the other Americans at Pau.

There seems to be a fascination to aviation, particularly when it is coupled with fighting. Perhaps it's because the game is new, but more probably because as a rule nobody knows anything about it. Whatever be the reason, adventurous young Americans were attracted by it in rapidly increasing numbers. Many of them, of course, never got fascinated beyond the stage of talking about joining. Among the chaps serving with the American ambulance field sections a good many imaginations were stirred, and a few actually did enlist, when, toward the end of the summer of 1915, the Ministry of War, finding that the original American pilots had made good, grew more liberal in considering applications.

Chouteau Johnson, of New York; Lawrence Rumsey, of Buffalo; Dudley Hill, of Peekskill, N.Y.; and Clyde Balsley, of El Paso; one after another doffed the ambulance driver's khaki for the horizon-blue of the French flying corps. All of them had seen plenty of action, collecting the wounded under fire, but they were all tired of being non-combatant spectators. More or less the same feeling actuated me, I suppose. I had come over from Carthage, N.C., in January, 1915, and worked with an American ambulance section in the Bois-le-Prêtre. All along I had been convinced that the United States ought to aid in the struggle against Germany. With that conviction, it was plainly up to me to do more than drive an ambulance. The more I saw the splendour of the fight the French were fighting, the more I felt like an embusqué--what the British call a "shirker." So I made up my mind to go into aviation.

A special channel had been created for the reception of applications from Americans, and my own was favourably replied to within a few days. It took four days more to pass through all the various departments, sign one's name to a few hundred papers, and undergo the physical examinations. Then I was sent to the aviation depot at Dijon and fitted out with a uniform and personal equipment. The next stop was the school at Pau, where I was to be taught to fly. My elation at arriving there was second only to my satisfaction at being a French soldier. It was a vast improvement, I thought, in the American Ambulance.

Talk about forming an all-American flying unit, or escadrille, was rife while I was at Pau. What with the pilots already breveted, and the élèves, or pupils in the training-schools, there were quite enough of our compatriots to man the dozen airplanes in one escadrille. Every day somebody "had it absolutely straight" that we were to become a unit at the front, and every other day the report turned out to be untrue. But at last, in the month of February, our dream came true. We learned that a captain had actually been assigned to command an American escadrille and that the Americans at the front had been recalled and placed under his orders. Soon afterward we élèves got another delightful thrill.

THREE TYPES OF FRENCH AIR SERVICE

Thaw, Prince, Cowdin, and the other veterans were training on the Nieuport! That meant the American Escadrille was to fly the Nieuport--the best type of avion de chasse--and hence would be a fighting unit. It is necessary to explain parenthetically here that French military aviation, generally speaking, is divided into three groups--the avions de chasse or airplanes of pursuit, which are used to hunt down enemy aircraft or to fight them off; avions de bombardement, big, unwieldy monsters for use in bombarding raids; and avions de réglage, cumbersome creatures designed to regulate artillery fire, take photographs, and do scout duty. The Nieuport is the smallest, fastest-rising, fastest-moving biplane in the French service. It can travel 110 miles an hour, and is a one-man apparatus with a machine gun mounted on its roof and fired by the pilot with one hand while with the other and his feet he operates his controls. The French call their Nieuport pilots the "aces" of the air. No wonder we were tickled to be included in that august brotherhood!
