"Every shot counts!" Sykes cried out to his men. As the attackers rode out of effective range he sighted four riderless horses. Beside him, in the barricade, one of his own men was hit and bleeding badly. A tourniquet was prepared until two men of the medical detail arrived with an improvised stretcher.

Sykes sat down and rested his head on his arms for a moment. The air was well below freezing, but his face was bathed with sweat. How long? he asked himself silently. How long can it go on? First the comet, then this. He roused at a sudden cry beside him.

"They're coming back," a man shouted. Sykes stood up and raised his fieldglasses to his eyes. From around the point a fresh group of riders was pouring toward the town. At least three times as many as before.

In a flash, he understood their intent. "They're going to come through!" he cried. "They're going to come right through the barrier, no matter what it costs them!"


Chapter 15.
Battle

The hard-riding nomad cavalry bore down on the defense line. They did not break into a circling column as before, but began forming an advancing line. When they were 75 yards away, Sykes ordered his men to begin firing.

The nomads were already shooting, and what their emissary had said was true: these men were expert shots, even from horseback. Sykes heard the bullets careening off the sloping face of the barricade. Two of his men were down already.

He leveled his police pistol and fired steadily into the oncoming ranks. He thought they were going to try to jump the fence this time, and he braced for the shock. To his dismay, he now saw that a perfectly clear space for their landing had been left between his own position and the adjacent barricade.

Suddenly the line of attackers swerved to the left just a few feet from the wire. The defending fire was furious, and for a moment Sykes thought they were going to turn the line back. Then several of the nomads raised their arms and hurled dark, small objects toward the barrier. Sykes recognized them even while they were in the air. Grenades.
