"Well, they are, sort of. They aren"t alive--at least, I don"t think they are--but they do what you tell them, and they learn tricks, and they have personalities."

That was true. He didn"t think robots were alive, either, though biophysics professors tended to become glibly evasive when pinned down to defining life. Robots could learn, if you used the term loosely enough. And any robot with more than five hundred hours service picked up a definite and often exasperating personality.

"I"ve been working with them, and tearing them down and fixing them, ever since I was in pigtails," she added.

The half-dozen natural leaders among the prisoners--Jacquemont and his daughter, the two _Harriet Barne_ officers, and a couple of others--bent over the photoprinted plans Conn had, located their position, and told him as much as they could about what lay ahead.

Sylvie Jacquemont could handle robots; she would ride in the front seat of the jeep while he piloted. Vibart, the chief engineer, and Yves Jacquemont would ride behind. Nichols would ride in the scow with the fighting men. One lorry of his own party would follow the jeep; the other would bring up the rear.

He snapped on the screen and punched the ship combination. Stefan Jorisson appeared in it.

"Hi, Conn! You all right?" He raised his voice. "Conn"s on-screen!"

His father appeared at Jorisson"s shoulder and, a moment later, Klem Zareff.

"Well, we"re in, all right," he said. "We just picked up an army, too." He swung the jeep to get the crowd in the pickup, explaining who they were. "Did you hear from Anse?"

"Yes, he just screened in," Rodney Maxwell said. "He said a gunboat can get in."

"That"s right; clear into the crater."

"Well, we"re going to put three of them inside," Zareff told him.

"_Werewolf_, _Zombi_, and _Dero_. And a troop carrier with fifty men; flamethrowers, portable machine guns, bomb-launchers; regular special-weapons section. What can you do where you are?"

"Here? Nothing. We"re going to work around to the other side of the crater, and then find a vertical shaft and go up topside and make as much disturbance as we can."

"That"s it!" Zareff approved. "Pull them off balance; as soon as we get in, we"ll go straight to the top. Look for us in about an hour; it"s going to take time getting to the tunnel-mouth without being spotted from above."

He lifted the jeep and started off; the lorry, and the scows and the other lorry, followed; the snooper and the bomb-robots went ahead like a pack of hunting dogs. They went through great chambers, dark and silent and bulking with dusty machines. Jacquemont explained that the prisoners had never gotten into this section; the _Harriet Barne_ was a mile or so to their right. Conn turned left, when the noise of firing from outside became plainer. A foundry. A machine-shop which seemed to have been abandoned in the middle of some rush job that hadn"t really been necessary. They came to a place even the snooper couldn"t enter, choked to the ceiling with dead vegetation, hydroponic seed-plants that had been left untended to grow wild and die. They emerged into outside light, in vast caves a mile high and open onto the crater, and looked across the floor that had been leveled and vitrified to the other side, three and a half miles away.

He didn"t know whether to be more awed by the original eruption that had formed the crater or by the engineering feat of carving these docks and ship-berths, big enough for the hugest hypers.p.a.ceship, into it.

At first, he had been afraid of getting into position too soon before the task force from outside could profit by the diversion. Then he began to worry about the time it was taking to get halfway around the crater. He could hear artillery thundering continuously above. Except at the very beginning of the battle, there had been little gunfire. He wondered if both sides were running out of lift-and-drive missiles, or if the fighting had gotten too close for anybody to risk using nuclear weapons.

He was also worrying about the women and children among the released prisoners.

"Why did the pirates bother with them?" he asked Sylvie.

"They used the women and some of the old men to do housekeeping ch.o.r.es for them," she said. "Mostly, though, they were hostages; if the men didn"t work, Perales threatened to punish the women and children. I wasn"t doing any housework; I"m too good a mechanic. I was helping on the ship."

"Well, what"ll I do with them when the fighting starts? I can"t take them into battle."

"You"ll have to; it"ll be the safest place for them. You can"t leave them anywhere and risk having them recaptured."

"That means we"ll have to detach some men to cover them, and that"ll cut our striking force down." He whistled at the sound-pickup of his screen and told his father about it. "What do I do with these people, anyhow?"

"You"re the officer in command, Conn," his father told him. "Your decision. How soon can you attack? We"re almost through to the crater."

"There"s a vertical shaft right above us, and a lot of noise at the top. We"ll send up a couple of bomb-robots to clear things at the shaft-head and follow with everything we have."

"Noncombatants and all?"

He nodded. "Only thing we can do." An old quotation occurred to him.

""If you want to make an omelet, you have to break eggs.""

He wondered who"d said that in the first place. One of the old Pre-Atomic conquerors; maybe Hitler. No, Hitler would have said, "If you want to make sauerkraut, you have to chop cabbage." Maybe it was Caesar.

"We"d better send Gumshoe Gus up, first," Sylvie suggested.

"You handle him. Take a quick look around, and then pull him back.

We"ll need him later." It was the first time he"d ever caught himself calling a robot "him," instead of "it." He thought for a second, and added: "Give your father and Mr. Vibart the controls for the two window-washers; you handle the snooper."

He gave more instructions: Yves Jacquemont to turn his bomb-robot right, Vibart to turn his left; the two lorries to follow the jeep up the shaft, the scows to follow. Then he leaned back and looked at the screens that had been rigged under the top of the jeep. A circle of light appeared in one, growing larger and brighter as the snooper approached the top of the shaft; two more came on as the bomb-robots followed.

"All right; follow me," he said into the inter-vehicle radio, and started the jeep slowly up the shaft.

The snooper popped out of the shaft, onto a gallery that had been cut into the solid rock, fifty feet high and a hundred and fifty across, with a low parapet on the outside and the mile-deep crater beyond.

There were a few grounded aircars and lorries in sight, and a medium airboat rested a hundred or so feet on the right of the shaft-opening.

Fifteen or twenty men were cl.u.s.tered around it, with a lifter loaded with ammunition. They looked like any crowd of farm-tramps. Suddenly, one of them saw the snooper, gave a yell, and fired at it with a rifle. Sylvie pulled it back into the shaft; her father and the chief engineer sent the two bomb-robots up onto the gallery. The right-hand robot sped at the airboat; the last thing Conn saw in its screen was a face, bearded and villainous and contorted with fright, looking out the pilot"s window of the airboat. Then it went dead, and there was a roar from above. On the other side, several men were firing straight at the pickup of the other robot; it went dead, too, and there was a second explosion.

In the communication screen, somebody was yelling, "Give them another one for Milt Hennant!" and his father was urging him to get in fast, before they recovered.

In peace or war, screen communication was a wonderful thing. The only trouble was that it let in too many kibitzers.

The gallery, when the jeep emerged onto it, was empty except for casualties, a few still alive. The side of the airboat was caved in; the lifter-load of ammunition had gone up with the bomb. He moved the jeep to the right of the shaft and waited for the vehicles behind him, suffering a brief indecision.

_Never divide your force in the presence of the enemy._

There had been generals who had done that and gotten away with it, but they"d had names like Foxx Travis and Robert E. Lee and Napoleon--Napoleon; that was who"d made that crack about omelets!

They"d known what they were doing. He was playing this battle by ear.

There was a lot of shouting ahead to the right. That meant live pirates, a deplorable situation which ought to be corrected at once.

The communication screen was noisy, now; his father had gotten to the top gallery with the three gun cutters, and was meeting resistance. He formed his column, his jeep and one of the lorries in front, the scows next, and the second lorry behind, and started around the gallery counterclockwise, the snoopers and the three remaining bomb-robots ahead. They began running into resistance almost at once.

Bullets spatted on the armor gla.s.s in front of him, spalling it and blotching it with metal until he found that he could steer better by the show-back of his view-pickup. He used that until the pickup was shot out. Then his father began wanting to know, from the communication screen, what was going on and where he was. A bomb or something went off directly under the jeep, bouncing it almost to the ceiling; he found that it was impossible to lift it again after it settled to the floor of the gallery, and they all piled out to fight on foot. Sommers and his gang from the number one lorry were also afoot; their vehicle had been disabled. He saw them lifting wounded into one of the scows.

They blew up the light-service robot to clear a nest of pirates who had taken cover ahead of them. They sent the robo-janitor up a side pa.s.sage and exploded it in a missile-launching position on the outside of the mountain; that produced a tremendous explosion. They began running out of cartridges, and had to stop and glean more from enemy casualties. They expended their last bomb-robot, the restaurant server, to break up another pirate resistance point.

At length he found himself, with Sylvie and her father and one of the Home Guardsmen from Sommers" lorry, lying behind an aircar somebody had knocked out with a bazooka, with two dead pirates for company and a dozen distressingly live ones ahead behind an improvised barricade.

Behind, there was frantic firing; the rear-guard seemed to have run into trouble, probably from some gang that had come down from the upper level. He wondered what his father was doing with the gunboats; since abandoning the jeep, he had lost his only means of contact.

Suddenly, the men in front jumped up from their barricade and came running toward him. Been reinforced, now they"re counterattacking. His rifle was empty; he drew his pistol and shot one of them, and then he saw that they were throwing up their hands and yelling for quarter.

This was something new.

He looked around quickly, to make sure none of the liberated prisoners except Jacquemont and his daughter were around, and then called to a couple of his own men to come up and help him. While they were relieving the pirates of their pistol belts and cartridge bandoliers, more came up, their hands over their heads, herded by a combat car from which Tom Brangwyn covered them with a pair of 12-mm machine guns. Tom hadn"t put in an appearance before he had taken his commando force into the tunnel; he hadn"t even known the chief of Company Police was on Barathrum.

"Well, nice seeing you," he greeted. "How did you get in?"

"Over the top," Brangwyn told him. "Everything"s caved in on the other side. We have a quarter of the top gallery, and half of this one. Your father"s cleaning up above. Klem"s got some men working along the outside."
