As the fuel capacity of a Nieuport allows but little more than two hours in the air the avions de chasse were forced to return to their own lines to take on more gasoline, while the bombardment planes continued on into Germany. The Sopwiths arrived first at Oberndorf. Dropping low over the Mauser works they discharged their bombs and headed homeward. All arrived, save one, whose pilot lost his way and came to earth in Switzerland. When the big machines got to Oberndorf they saw only flames and smoke where once the rifle factory stood. They unloaded their explosives on the burning mass.

The Nieuports having refilled their tanks went up to clear the air of Germans that might be hovering in wait for the returning raiders. Prince found one and promptly shot it down. Lufbery came upon three. He drove for one, making it drop below the others, then forcing a second to descend, attacked the one remaining above. The combat was short and at the end of it the German tumbled to earth. This made the fifth enemy machine which was officially credited to Lufbery. When a pilot has accounted for five Boches he is mentioned by name in the official communication, and is spoken of as an "Ace," which in French aërial slang means a super-pilot. Papers are allowed to call an "ace" by name, print his picture and give him a write-up. The successful aviator becomes a national hero. When Lufbery worked into this category the French papers made him a head liner. The American "Ace," with his string of medals, then came in for the ennuis of a matinee idol. The choicest bit in the collection was a letter from Wallingford, Conn., his home town, thanking him for putting it on the map.

Darkness was coming rapidly on but Prince and Lufbery remained in the air to protect the bombardment fleet. Just at nightfall Lufbery made for a small aviation field near the lines, known as Corcieux. Slow-moving machines, with great planing capacity, can be landed in the dark, but to try and feel for the ground in a Nieuport, which comes down at about a hundred miles an hour, is to court disaster. Ten minutes after Lufbery landed Prince decided to make for the field. He spiraled down through the night air and skimmed rapidly over the trees bordering the Corcieux field. In the dark he did not see a high-tension electric cable that was stretched just above the tree tops. The landing gear of his airplane struck it. The machine snapped forward and hit the ground on its nose. It turned over and over. The belt holding Prince broke and he was thrown far from the wrecked plane. Both of his legs were broken and he naturally suffered internal injuries. In spite of the terrific shock and his intense pain Prince did not lose consciousness. He even kept his presence of mind and gave orders to the men who had run to pick him up. Hearing the hum of a motor, and realizing a machine was in the air, Prince told them to light gasoline fires on the field. "You don't want another fellow to come down and break himself up the way I've done," he said.

Lufbery went with Prince to the hospital in Gerardmer. As the ambulance rolled along Prince sang to keep up his spirits. He spoke of getting well soon and returning to service. It was like Norman. He was always energetic about his flying. Even when he passed through the harrowing experience of having a wing shattered, the first thing he did on landing was to busy himself about getting another fitted in place and the next morning he was in the air again.

No one thought that Prince was mortally injured but the next day he went into a coma. A blood clot had formed on his brain. Captain Haff in command of the aviation groups of Luxeuil, accompanied by our officers, hastened to Gerardmer. Prince lying unconscious on his bed, was named a second lieutenant and decorated with the Legion of Honor. He already held the Médaille Militaire and Croix de Guerre. Norman Prince died on the 15th of October. He was brought back to Luxeuil and given a funeral similar to Rockwell's. It was hard to realize that poor old Norman had gone. He was the founder of the American escadrille and every one in it had come to rely on him. He never let his own spirits drop, and was always on hand with encouragement for the others. I do not think Prince minded going. He wanted to do his part before being killed, and he had more than done it. He had, day after day, freed the line of Germans, making it impossible for them to do their work, and three of them he had shot to earth.

Two days after Prince's death the escadrille received orders to leave for the Somme. The night before the departure the British gave the American pilots a farewell banquet and toasted them as their "Guardian Angels." They keenly appreciated the fact that four men from the American escadrille had brought down four Germans, and had cleared the way for their squadron returning from Oberndorf. When the train pulled out the next day the station platform was packed by khaki-clad pilots waving good-bye to their friends the "Yanks."

The escadrille passed through Paris on its way to the Somme front. The few members who had machines flew from Luxeuil to their new post. At Paris the pilots were reënforced by three other American boys who had completed their training. They were: Fred Prince, who ten months before had come over from Boston to serve in aviation with his brother Norman; Willis Haviland, of Chicago, who left the American Ambulance for the life of a birdman, and Bob Soubrian, of New York, who had been transferred from the Foreign Legion to the flying corps after being wounded in the Champagne offensive.
