Bell turned the Eagle around and flew back up the tracks in the direction from which he had come. Facing east, back toward Fort Worth, he saw the gray glow of first light. His keen eyes detected a dot several miles distant. Josephine was coming at sixty miles at hour. He had two minutes to disable the machine guns before she ran into the clouds of lead they were shooting into the sky. But armed with a single Remington rifle, he was badly outgunned. His only hope was to sow confusion.

He blipped his motor off again, banked, and glided silently to the right. He blipped on. The south gun chattered, tracing the noise of his motor but revealing its position. Bell steered for the flashes, swooped low, and fired his rifle. He blipped off the motor and glided over the machine gun. Well past it, he blipped the Gnome again, roared around, and headed back, flying in line with the guns on a course perpendicular to the tracks.

Both guns, the closer south gun and the north gun on the far side of the tracks, opened a deadly sheet of fire. Bell swooped low over the nearer. By its muzzle flashes, he could see three men had the gun mounted on a light landing carriage, which they wheeled skillfully as he passed to rake him from behind.

Bell dropped under the stream of bullets, so low he could see flashes on the tracks. Harry Frost was firing a shotgun at the Gnome’s brightly flaming exhaust. Bell dropped almost to the ground, practically parted Frost’s hair with his skids, and fired his rifle at the north machine gunners, drawing their attention and causing them to wheel their gun and fire at him continuously. Had they held the trigger any longer, the air-cooled Colt would have burned up. As it was he could see the barrel glowing red-hot. But they stopped firing abruptly and scattered for their lives as their emplacement was hit by a burst from the south gunners, whom Bell had tricked into strafing their opposite position while trying to rake him from behind.

A second later, the south gun exploded when the last bullets from the northern emplacement they put out of action ignited their ammunition boxes.

Bell slammed the Eagle in another tight turn and fired his last shots from the Remington at the shotgun flashes. He stood little chance of hitting Frost in the dim light from his racing machine but hoped that Remington .35 slugs shrieking near Frost’s head would make the murderer dive for cover.

Frost didn’t budge.

He stood erect, firing repeatedly, until his shotgun was empty.
