She ducked as a slung stone shot by her head. "It was not an easy thing for me," she admitted. "Sim! Be careful!"
The boulders began to roll in a synthetic avalanche from the battlements of the enemy!
Only one thought was in his mind now. To kill, to lessen the life of someone else so he could live, to gain a foothold here and live long enough to make a stab at the ship. He ducked, he weaved, he clutched stones and hurled them up. His left hand held a flat stone shield with which he diverted the swiftly plummeting rocks. There was a spatting sound everywhere. Lyte ran with him, encouraging him. Two men dropped before him, slain, their breasts cleaved to the bone, their blood springing out in unbelievable founts.
It was a useless conflict. Sim realized instantly how insane the venture was. They could never storm the cliff. A solid wall of rocks rained down. A dozen men dropped with shards of ebony in their brains, a half dozen more showed drooping, broken arms. One screamed and the upthrust white joint of his knee was exposed as the flesh was pulled away by two successive blows of well-aimed granite. Men stumbled over one another.
The muscles in his cheeks pulled tight and he began to wonder why he had ever come. But his raised eyes, as he danced from side to side, weaving and bobbing, sought always the cliffs. He wanted to live there so intensely, to have his chance. He would have to stick it out. But the heart was gone from him.
Lyte screamed piercingly. Sim, his heart panicking, twisted and saw that her hand was loose at the wrist, with an ugly wound bleeding profusely on the back of the knuckles. She clamped it under her armpit to soothe the pain. The anger rose in him and exploded. In his fury he raced forward, throwing his missiles with deadly accuracy. He saw a man topple and flail down, falling from one level to another of the caves, a victim of his shot. He must have been screaming, for his lungs were bursting open and closed and his throat was raw, and the ground spun madly under his racing feet.
The stone that clipped his head sent him reeling and plunging back. He ate sand. The universe dissolved into purple whorls. He could not get up. He lay and knew that this was his last day, his last time. The battle raged around him, dimly he felt Lyte over him. Her hands cooled his head, she tried to drag him out of range, but he lay gasping and telling her to leave him.
"Stop!" shouted a voice. The whole war seemed to give pause. "Retreat!" commanded the voice swiftly. And as Sim watched, lying upon his side, his comrades turned and fled back toward home.
"The sun is coming, our time is up!" He saw their muscled backs, their moving, tensing, flickering legs go up and down. The dead were left upon the field. The wounded cried for help. But there was no time for the wounded. There was only time for swift men to run the gauntlet home and, their lungs aching and raw with heated air, burst into their tunnels before the sun burnt and killed them.
