And so the story runs; each new adventure a companion thriller to the others, every machine in which he flew being more or less riddled with bullets, and the miracle is that the daring youth passed so many hazards unscathed. Col. Hartney is authority for the statement that balloon strafing is in reality “the most dangerous exploit any man in any branch of the service can undertake.” Frank Luke in seventeen days accounted for eighteen enemy balloons and planes. He was the first American flyer to win the Congressional Medal of Honor. HIS END A MYSTERY But there is an end to successful adventures as to other things, and the brilliant career of this Arizona lad came to abrupt conclusion, leaving the shadow of mystery as to just how the hero passed on. Here is the story of the last exploit as Col. Hartley tells it: “His next official victory was on Sept. 28, when he shot down a German Hanoveraner airplane which was being escorted by a single-seater Fokker. “That evening he did not return to his own aerodrome, but remained all night with the French squadron and went out the next day for the express purpose of destroying three balloons. The wonderful story of his exciting fight against hopeless odds and of his glorious death need not be dwelt upon. For his work on Sept. 29 he was awarded the Medal of Honor. “Briefly, what happened was that he flew over an American aerodrome and dropped a weighted message. The message asked that a lookout be kept for three drachens over on the German side. He was next seen to go over in that direction at a very high altitude, and when very nearly over the drachens was attacked by ten enemy machines. He engaged all of them single-handed and crashed two of the ten. Then he dropped—out of control, as it seemed, but most likely only pretending to be so. When he reached the level of the balloons he shot them down one after another in flames—all three of them. The anti-aircraft guns were very busy about the second balloon. After that he disappeared.” Beyond this all that is known is more or less speculative. Jan. 3, 1919, the Graves Registration officer of Neufchateau reported to the Chief of the A. E. F. Air Service on the subject of the grave of an unknown American aviator, killed Sept. 29, 1918, in the village of Murvaux (Meuse), and asked for possible information to identify the body. “Reported as having light hair, young, of medium height and rugged physique. Reported by the inhabitants that previous to being killed this man brought down three German balloons, two German planes and dropped hand bombs, killed eleven German soldiers and wounded a number of others. He was wounded himself in the shoulder and evidently had to make a forced landing, and upon landing opened fire with his automatic and fought until he was killed. It is also reported that the Germans took his shoes, leggings and money, leaving his grave unmarked.”
