The Englishman's voice sounded bubbly. "I can make it."

"Good for you!" Rip exclaimed. "Call for help if you need it."

Koa was already out of the craft and leading the way. Rip went out through a window and saw the cause of the trouble. Dowst had been a hair too close to the asteroid. A particularly high crystal of thorium had snagged the craft.

Rip looked for the Connie and saw it starting another turn. They had only a moment or two before the next run. "Show an exhaust," he called. The Connie must have blasted the opposite side of the asteroid while they were hung up.

The cave was a quarter of the asteroid away. Rip stayed in the rear, watching for stragglers. But even Bradshaw was moving rapidly. Koa reached the cave well ahead of the rest, reached for a rack of rockets, and slapped it into the launcher.

Rip urged the men on. The Connie was squared off for another run.

They catapulted to safety as the cruiser flamed past, the exhaust splashing over the metal and sending sparks into the cave.

Rip looked out. That, if he had guessed right, was the last run. He watched the Connie's stern jet cut off, saw the nose exhaust as the cruiser decelerated to a fast stop.

"Check your weapons," he ordered.

He pulled his pistol from the knee pocket and checked it carefully. There was a clip in the magazine. Other clips were in his pocket. The clips were loaded with high velocity sh.e.l.ls that exploded on contact. One slug could stop a Venusian _krel_, a mammoth beast that had been described as a cross between a sea lion and a cactus plant.

His knife was in place in the other knee pocket.

The Connie cruiser decelerated, went into reverse, and came to a full stop about a mile from the asteroid. The Planeteers saw fire in two places along the hull, marking the exhausts of two small craft.

"Snapper-boats," Koa said tonelessly. "Five men in each, if those are the regular Connie kind."

Rip made a quick decision. With only one launcher they couldn't guard the whole asteroid. "We'll stay under cover, except for Santos and Pederson.

You two sneak out. Take advantage of every bit of cover you can find. I don't want you spotted. When a boat lands, report its position. The Connies operate on different communicator frequencies, so they won't overhear. Well let them think they've burned the asteroid clean."

He paused. "They'll search for a while. Then, when they're pretty well satisfied that all is quiet, we'll show up." Rip grinned at his Planeteers. "We can have a real, old-fashioned surprise party."

Koa slid the safety catch from his pistol. "With fireworks," he added.

CHAPTER NINE - REPEL INVADERS!

The snapper-boats came out of the darkness of s.p.a.ce, leaving a glowing trail of fire. They were not graceful. Rip could see no beauty in their lines, but to his professional eye there was plenty of deadly efficiency.

The Connie fighting craft looked like three globes strung evenly on a steel tube. The middle globe was larger than the end ones, and it was transparent. From it projected the barrels of two kinds of weapons-explosive and ultrasonic. Five men usually rode in the middle ball. One piloted. The other four were gunners.

The end globes were pierced by five large holes. They were blast holes for the rocket exhaust. Unlike the landing boats, each tube did not have its own fuel supply. One fuel tank served each globe. The pilot could direct the exhaust through any tube or combination of tubes he wished, by operating valves that either sealed or opened the vents.

The system gave high maneuverability to the boats. By playing on the controls with the skill of an organist, the pilot could shift direction with dazzling speed.

Snapper-boats used by the Federation operated on the same principle, but they were of American design, and they showed the American's love of clean lines. Federation fighter craft were slim and streamlined, even though the streamlining was of no use whatever in s.p.a.ce. With blast holes at each end, they looked like double-ended needles. The pilot's canopy in the center controlled guns that fired through the front only. Rear guns were handled by a gunner, who sat with back to the pilot.

Where Connie snapper-boats carried five men, the Federation boats carried two. The Connies could fire in any direction. The Federation pilots aimed by pointing the snapper-boat itself, as fighter pilots of conventional aircraft had once aimed their guns.

Rip watched the boats approach. He was ready to duck inside if they decided to look the asteroid over before landing. He hoped they wouldn't catch sight of his two scouts. He also hoped his nervousness would vanish when the fight started. He knew what to do, at least in theory. He had gone through combat problems on the moon during training. But this was different. This was real. The lives of his men depended on his being right, and he was afraid of making a wrong decision.

Sergeant-major Koa, an experienced Planeteer with a lot of understanding, came and stood beside him. He said, "Guess I'll never get over being jittery while waiting for the fight to start. I'm sweating so hard my dehumidifier is humming like a Callistan honey lizard. But it doesn't last long once the shooting begins. I get so busy I forget to be jittery."

Before Rip could reply, the snapper-boats flashed over the cave, circled the asteroid once, and landed on the dark side close by the bomb craters.

The first scout reported. "Santos, sir. I'm fifty yards beyond the stakes where we had the first base. The snapper-boats landed between the first two craters. Men coming out of one boat. I count six. Now they're coming out of the other boat, but I can't see very well."

The other scout picked up the report, his Swedish accent thick with excitement. "I can see them, sor! By Cosmos! There be seven in this boat on my side. I am behind a rock forty yards to sunward of the second crater."

Rip turned up the volume of his communicator. "How are they armed? Santos, report."

"One is carrying a pneumatic chattergun. The rest have nothing in their hands."

"Pederson, report."

"No weapons I can see, sor."

Koa looked at Rip. "They must think the asteroid is clean. Otherwise they'd have more than a chattergun in sight. You can bet they have knives and pistols, too."

Rip had been playing with an idea. He tried it on his men. "These Connies would be useful to us alive, if we could capture them."

It was Dowst who caught his meaning first. "You mean as hostages, sir?"

"That's it. If we could capture them, the Connie cruiser would be helpless. We could use the snapper-boat radios to warn the ship that any false move would mean harm to their men."

Koa shook his head doubtfully. "I'm not sure the Connies worry about their men, but it's worth the try. We can capture some of them if they split up to search the asteroid. But we won't be able to sneak up on them all."

"We have an advantage," Rip reminded them. "We've been on the asteroid longer. We know our way around, and we're used to s.p.a.ce-walking. They've just come out of deceleration and they won't have their s.p.a.ce-legs yet."

Santos reported. "They're breaking up into groups of two. Three are guarding the snapper-boats. One is the man with the chattergun."

"Are their belt lights on?"

"Yes."

"Then keep out of the beams. Don't let them walk into you. Keep low, and keep moving. Stay over on the dark side."

"We'd better get to the dark side ourselves," Koa warned.

He was right, Rip knew. The Connies didn't have far to search before reaching the sun side. "Koa, you take Trudeau and Kemp. I'll take Dowst and Dominico. Nunez and Bradshaw stay here to guard the cave. If they arrive in twos, let them get into the cave before you jump them. Bradshaw, how do you feel?"

"I'm all right, Lieutenant."

Rip admired the Planeteer's nerve. He knew Bradshaw was in pain, because bleeding into high vacuum was always painful. The crack in the English-man's helmet had let most of the air out, and his own blood pressure had done the rest. He would carry the marks for days. A few more moments and all air and all heat would have been gone, with fatal results.

Fortunately, bubbles didn't shatter easily when cracked. To destroy them took a good blow that knocked out a piece.
