Among the American aviators who have been most successful is Lieutenant Thaw. He has fought sixteen battles and brought down five adversaries. His machine received several bullets while over the German lines at Verdun, one of which hit him in the elbow, breaking a small bone. He has recovered, and is again with the Corps. Sergeant Kiffin Rockwell destroyed a German ‘plane on May 18, and attacked several on May 26, when he was badly wounded in the face. He brought down two German machines during the battle at Verdun. Sergeant Bert Hall, after a long, hard fight on May 22, brought down a German from a height of 13,000 feet. He followed it down 3,000 feet, and saw it crash to the ground just within the German lines. On September 25, 1916, French _avions de chasse_ fought forty-seven engagements on the Somme front. Five enemy machines were brought down, while three more, which were seriously damaged, were obliged to alight. Another machine, which was attacked at close quarters with a machine-gun, fell disabled, but could not be followed to the ground. During these engagements, Sous-Lieutenant Heurtaux brought down his eighth machine in the direction of Villers Carbonnel, and Adjutant Dorme his twelfth machine north of Lieramont. In the Woevre, Adjutant Lenoir attacked an enemy machine constructed to carry three, and after a very hard fight brought it down near Fromezey (north-west of Etain). This was the eleventh machine brought down by this pilot. Further aerial combats, which again resulted in victory for the French aviators, were fought on September 27. Sous-Lieutenant Nungesser in the course of the day alone brought down two German aeroplanes between Le Transloy and Rocquigny, and an enemy captive balloon, which fell in flames in the Neuville district. These three victories bring up to seventeen the number of machines brought down by this pilot. Moreover, two other German aeroplanes which had been seriously hit fell out of control—one towards Le Transloy and the other near Le Mesnil Bruntel. Another captive balloon, attacked by French pilots, collapsed near Nurlu. In Champagne a Fokker, attacked at close quarters, fell at first in spirals, then vertically, and was smashed, crashing to the ground at Grateuil. It is noteworthy that the much-vaunted German Fokker machine was now under the shadow of defeat. On September 27 a Fokker, on being attacked by a French pilot, crashed to the ground near Rheims. Another, shortly after, ‘nose-dived’ into its own lines. Many other German machines of the same type fell victims to the courageous and skilful French aviators.
