A captain, the commandant of an Alsatian village, watched the aërial battle through his field glasses. He said that Rockwell approached so close to the enemy that he thought there would be a collision. The German craft, which carried two machine guns, had opened a rapid fire when Rockwell started his dive. He plunged through the stream of lead and only when very close to his enemy did he begin shooting. For a second it looked as though the German was falling, so the captain said, but then he saw the French machine turn rapidly nose down, the wings of one side broke off and fluttered in the wake of the airplane, which hurtled earthward in a rapid drop. It crashed into the ground in a small field--a field of flowers--a few hundred yards back of the trenches. It was not more than two and a half miles from the spot where Rockwell, in the month of May, brought down his first enemy machine. The Germans immediately opened up on the wreck with artillery fire. In spite of the bursting shrapnel, gunners from a nearby battery rushed out and recovered poor Rockwell's broken body. There was a hideous wound in his breast where an explosive bullet had torn through. A surgeon who examined the body, testified that if it had been an ordinary bullet Rockwell would have had an even chance of landing with only a bad wound. As it was he was killed the instant the unlawful missile exploded. Lufbery engaged a German craft but before he could get to close range two Fokkers swooped down from behind and filled his aeroplane full of holes. Exhausting his ammunition he landed at Fontaine, an aviation field near the lines. There he learned of Rockwell's death and was told that two other French machines had been brought down within the hour. He ordered his gasolene tank filled, procured a full band of cartridges and soared up into the air to avenge his comrade. He sped up and down the lines, and made a wide détour to Habsheim where the Germans have an aviation field, but all to no avail. Not a Boche was in the air. The news of Rockwell's death was telephoned to the escadrille. The captain, lieutenant, and a couple of men jumped in a staff car and hastened to where he had fallen. On their return the American pilots were convened in a room of the hotel and the news broken to them. With tears in his eyes the captain said: "The best and bravest of us all is no more."
