After what seemed a long while, the invaders reached a point overlooking Drone Baker. One of the figures remained on a small rise overlooking the drone while the other two separated and approached it from different directions. The tactic disquieted him. It indicated that the newcomers were not entirely convinced that they were alone in Crater Arzachel.

After another interminably long time, the two figures approaching the rocket met at its base. They walked around the rocket several times, then struck out, this time toward Drone Charlie. Their companion left his lookout point and cut across the plain to join them.

Crag squirmed uncomfortably. He was tired and hungry; his muscles ached from the constriction of the suit. His body was hot and clammy, and perspiration from his brow stung his eyes. He sighed, wishing he had a cigarette. Strange, he hadn't smoked in over a year but all at once the need for tobacco seemed overwhelming. He pushed the thought aside.

The invaders were strung out in single file, moving in a direction which brought them closer to his position. He shifted to a point below the crest, moving slowly to avoid detection. Their path crossed his field of vision at a distance of about half a mile. At the closest point he saw they carried rifles in shoulder slings. He took this as another indication they suspected the presence of survivors. The invaders stopped and rested at a point almost opposite him. He fidgeted, trying to get his body into a more comfortable position.

Finally they resumed their trek. Before they reached the drone they halted. One man remained in the cover of a spur of rock while the other two separated and advanced on the drone from different directions. Crag cursed under his breath. They certainly weren't going to be sitting ducks. Perhaps it was just a precaution. Simply good infantry tactics, he told himself, but it still raised a complication.

He waited. The two invaders closed on the drone, meeting at its base. They evidently decided it was abandoned, for they left within a few minutes walking to join their waiting companion. After a short huddle they struck out in the direction of Bandit. This was the move he had waited for.

He withdrew to the lee side of the ridge and picked his way toward Bandit as rapidly as possible, taking care not to brush against the sharp slivers of rock. He drew near the rocket, thinking that the open hatch would be a dead giveaway. Still, there was no alternative. A fort without a gunport was no fort at all. He climbed to a spot close to the crest of the ridge and peered back in the direction of the invaders, startled to find they were nearer than he had supposed. He hastily withdrew his head, deciding it was too late to warn the others to abandon the rocket. If the invaders climbed straight up the opposite side of the ridge, they conceivably could catch his crew on the open plain. That made another complication.

He scanned the ridge. Off to his right a series of granite spurs jutted from the base rock in finger formation. He picked his way toward them, then descended until he found shelter between two rock outcroppings which gave him a clear view of Bandit. He checked his automatic rifle, moving the control lever to the semi-automatic position. The black rectangle that marked Bandit's hatch seemed lifeless.

He waited.

Long minutes passed. He cursed the eternal silence of the moon which robbed him of the use of his ears. A cannon could fire within an inch of his back and he'd never know it, he thought. He moved his head slightly forward from time to time in an effort to see the slope behind him. Nothing happened. His body itched intolerably from perspiration. He readjusted the suit temperature setting, gaining a slight respite from the heat. All at once he caught movement out of the corner of his face plate and involuntarily jerked his head back. He waited a moment, aware that his heart was pounding heavily, then cautiously moved forward. One of the invaders was picking his way down the slope in a path that would take him within thirty yards of his position. The man moved slowly, half-crouched, keeping his rifle cradled across his arm.
