Murphy raised his head. He could tell from the flashes of artillery fire that they were surrounded. Antarian artillery had a purplish flash of light that their own guns did not have. And he could see: in every direction there was an occasional flash of purplish light. The flashes formed a circle--a circle around them. He lowered himself into the foxhole. "What?" Hank inquired. "Surrounded." "Are you sure?" Hank crouched in the semi-darkness as if about to pounce on something. "Damn it, if you don't believe me, _take a look_!" Hank hesitated. He was a tall, lanky person with red hair and boyish freckles. He had an awkward, self-conscious manner, and despite his powerful body, the freckles and manner made others think of him as a boy rather than a man. He was eighteen and combat had hardened his muscles without hardening his appearance. "I believe you," he said. "Do you think we'll get out?" "Hard to tell. Maybe." Murphy leaned back and looked up at the dark sky. It was filled with stars, stars that twinkled, and intermingled with them were other points of light that were not stars. They were atomic explosions, and unlike the stars, they did not twinkle. An atomic explosion in outer space, without the pressure of atmosphere, expanded tremendously. When it reached the limit of expansion, it faded, and watching a battle in outer space was like watching a maze of tiny blinking lights. Murphy watched those tiny blips of light every night. One night, if he lived long enough, there would be no blips of light and that would mean that one side was beaten. They were fighting and dying on Antares but their battle was a secondary one. It was the battle in outer space that would win the war. If the Antarians won that battle, then every Earthman on Antares would die because there would be no more supplies. If Earth won that battle, the Antarians would be beaten since they would have no way to stop Earth from sending more men and more supplies. He closed his eyes and tried to concentrate on the problem of saving Hank's life. That was his habit: every time he went into combat, he picked someone like Hank--a kid--and stuck with him. He would worry about that kid, whoever he might be, and try to keep him out of tight spots. It was his way of protecting himself. Whenever he worried about his own life, his mind always froze. But worrying about someone else was different. "I think I'd rather die than be captured," Hank said. "I heard they have ways of making a guy talk--ways of making a guy tell them anything."
