Burl realized that as far as he was concerned, he was not in any better shape than his allies. His oxygen tanks were slowly but surely emptying. He examined his gauges and was startled to see he had only two more hours before suffocation would set in. The suit was warmed by batteries which would last several days longer, but by that time it would be too late. Somewhere inside his suit he had a pocket knife, but he could not get at it in the frigid near-airlessness of the outer surface. His holster still hung at his side, but it was empty. There was nothing to do then but to join the Neptunian assault. He would try to open the door by the electronic charge that still remained in his body. If he did, they could break in and do what they could. If he could not, who knew what would happen? Burl picked up one of the Plutonian weapons and gestured to the rest to prepare to attack. Immediately, they fell into orderly ranks. They were, indeed, soldiers, Burl thought--the cream of their planet's armies--whatever that meant in Terrestrial terms. Then, following the lead of the Neptunian captain, they marched out of the forest. As they crossed the open plain, Burl knew that they were probably in sight of the defenders. But he realized quickly that that had been true when he was released and nothing had happened. So perhaps he was wrong. Perhaps the Plutonians were limited--perhaps they had not bothered to keep a watch. That left only the Plutonian spaceships to worry about. Burl hastily searched the sky and located two glowing spots--four really--undoubtedly two of the double-sphere ships. The Neptunians behind bumped into him, then the whole column came to a halt. Burl pointed to the ships. The commander waved his arms helplessly. They had been there all along, Burl gathered, and what could he do about it? More gestures. Yes, the ships were dangerous. In fact, they had been the ones that had defeated the main Neptunian attack, blasted them from the sky and destroyed the ship in which the stick-man army had arrived. The Neptunians were going to attack, regardless. Again, Burl realized the essentially suicidal mood that moved these beings. They were attacking against odds before which they were utterly helpless. Even as Burl stared at the far-off lights of the Plutonian ships, he noticed them swing away, moving off toward the horizon. As he watched, he thought for an instant that something else had blinked like a star, far in the distance. Struck by a sudden thought, he activated his helmet radio. "Burl Denning calling the _Magellan_! He spoke at maximum power into his throat mike. Calling the _Magellan_! If you can hear me, reply!" Then, to his joy, a faint, far-away voice answered, "Burl Denning! This is Lockhart. Give us your location." "Lockhart! There are two Pluto ships approaching you from the direction in which you can hear my voice. Be careful!"
