He snatched up the missile and wound up as if pitching one straight over the corner of the plate. The horseman saw the motion of his arm and tried to whirl, but he was too late. The brickbat caught him at the side of the head and he dropped to the snow without a sound. Ken ran forward and caught up the nomad's rifle and ammunition belt. The horse had fled in panic.

Without a backward glance Ken raced on down the street toward the dwindling sound of battle. The invaders were retreating, streaming from all directions toward the break in the barrier, firing steadily as they came. The defenders were trying to block the escape.

Ken dropped behind a barricade next to an older man he didn't know. He searched for an opening and waited for a rider to cross his sights; then he squeezed the trigger and the man fell. When he looked up again the last of the invaders were gone. Only half of those who had come up to the attack were leaving it.

The men around Ken slowly relaxed their terrible tension. From some lying prone there were cries of pain. Those who could stand did so and revealed their drawn faces to one another.

Teams of the medical group began moving again. A horse-drawn wagon was brought up that had been fitted with boards across the sides so that two layers of wounded men could be carried at once.

Ken heard sudden hoofbeats behind and turned. Sheriff Johnson rode up and surveyed the scene. His eye caught Ken's figure standing in the midst of it, rifle in hand, the captured ammunition belt draped over his shoulder.

"You!" White anger was on Johnson's face. "You were ordered to stay out of the frontline!" he thundered. "Any other man would be court-martialed for such disobedience. Get back where you belong and don't show your face in this area again. I'll jail you for the rest of the fighting if you disobey again!"

Half-ashamed, but half only, for his impulsive action, Ken turned and moved down the street.

"Leave that gun here!" the Sheriff commanded harshly.

Ken gave it to the nearest soldier. He took off the ammunition belt and handed it over too, then resumed his course. He should not have done it, he told himself, but he felt better for it. He felt he had paid a little of his debt to Mr. Harris.
