"Why aren't you dead?" Ender asked him. "You fought your battle seventy years ago. I don't think you're even sixty years old."
"The miracles of relativity," said Mazer. "They kept me here for twenty years after the battle, even though I begged them to let me command one of the starships they launched against the bugger home planet and the bugger colonies. Then they -- came to understand some things about the way soldiers behave in the stress of battle."
"You've never been taught enough psyholgy to understand. Enough to say that they realized that even though I would never be able to command the fleet -- I'd be dead before the fleet even arrived -- I was still the only person able to understand the things I understood about the buggers. I was, they realized, the only person who had ever defeated the bugeers by intelligence rather than luck. They needed me here to teach the person who *could* command the fleet."
"So they sent you out in a starship, got you up to a relativistic speed--"
"And then I turned around and came home. A very dull voyage, Ender. Fifty years in space. Officially, only eight years passed for me, but it felt like five hundred. All so I could teach the next commander everything I knew."
"Am I to be the commander, then?"
"Let's say that you're our best bet at present."
"There are others being prepared, too?"
"That makes me the only choice, then, doesn't it'?"
"Except you. You're still alive, aren't you? Why not you?"
Mazer shook his head.
"Why not? You won before."
"I cannot be the commander for good and sufficient reasons."
"Show me how you beat the buggers, Mazer."
Mayer's face went inscrutable.
"You've shown me every other battle seven times at least. I think I've seen ways to beat what the buggers did before, but you've never shown me how you actually did beat them."
"The video is a very tightly kept secret, Ender."
"I know. I've pieced it together, partly. You, with your tiny reserve force, and their armada, those great big heavy-bellied starships launching their swarms of fighters. You dart in at one ship, fire at it, an explosion. That's where they always stop the clips. After that, it's just soldiers going into bugger ships and already finding them dead inside."
Mazer grinned. "So much for tightly kept secrets. Come on, let's watch the video."
They were alone in the video room, and Ender palmed the door locked. "All right, let's watch."
The video showed exactly what Ender had pieced together. Mazer's suicidal plunge into the heart of the enemy formation, the single explosion, and then--
Nothing. Mazer's ship went on, dodged the shock wave, and wove his way among to other bugger ships. They did not fire on him. They did not change course. Two of them crashed into each other and exploded, a needless collision that either pilot could have avoided. Neither made the slightest movement.
Mazer sped up the action. Skipped ahead. "We waited for three hours," he said. "Nobody could believe it." Then the IF ships began approaching the bugger starships. Marines began their cutting and boarding operations. The videos showed the buggers already dead at their posts.
"So you see," said Mazer, "you already knew all there was to see."
"Why did it happen?"
"Nobody knows. I have my personal opinions. But there are plenty of scientists who tell me I'm less than qualified to have opinions."
"You're the one who won the battle."
"I thought that qualified me to comment, too, but you know how it is. Xenobiologists and xenopsychologists can't accept the idea that a starpilot scooped them by sheer guesswork. I think they all hate me because, after they saw these videos, they had to live out the rest of their natural lives here on Eros. Security, you know. They weren't happy."
"The buggers don't talk. They think to each other, and it's instantaneous like the philotic effect. Like the ansible. But most people always thought that meant a controlled comunication like language -- I think you a thought and then you answer me. I never believed that. It's too immediate, the way they respond together to things. You've seen the videos. They aren't conversing and deciding among possible courses of action. Every ship acts like part of a single organism. It responds the way your body responds during combat, different parts automatically, thoughtlessly doing everything they're supposed to do. They aren't having a mental conversation between people with different thought processes. All their thoughts are present, together, at once."
"A single person, and each bugger is like a hand or a foot?"
"Yes. I wasn't the first person to suggest it, but I was the first person to believe it. And something else. Something so childish and stupid that the xenobiologists laughed me to silence when I said it after the battle. The buggers are bugs. They're like ants and bees. A queen, the workers. That was maybe a hundred million years ago, but that's how they started, that kind of pattern. It's a sure thing none of the buggers we saw had any way of making more little buggers. So when they evolved this ability to think together, wouldn't they still keep the queen? Wouldn't the queen still be the center of the group? Why would that ever change?"
"So it's the queen who controls the whole group."
"I had evidence, too. Not evidence that any of them could see. It wasn't there in the First Invasion, because that was exploratory. But the Second Invasion was a colony. To set up a new hive, or whatever."
"And so they brought a queen."
"The videos of the Second Invasion, when they were destroying our fleets out in the comet shell." He began to call them up and display the buggers' patterns. "Show me the queen's ship."
It was subtle. Ender couldn't see it for a long time. The bugger ships kept moving, all of them. There was no obvious flagship, no apparent nerve center. But gradually, as Mazer played the videos over and over again, Ender began to see the way that all the movements focused on, radiated from a center point. The center point shifted, but it was obvious, after he looked long enough, that the eyes of the fleet, the *I* of the fleet, the perspective from which all decisions were being made, was one particular ship. He pointed it out.
"You see it. I see it. That makes two people out of all of those who have seen this video. But it's true, isn't it."
"They make that ship move just like any other ship."
"They know it's their weak point."
"But you're right. That's the queen. But then you'd think that when you went for it, they would have immediately focused all their power on you. They could have blown you out of the sky."
"I know. That part I don't understand. Not that they didn't try to stop me -- they were firing at me. But it's as if they really couldn't believe, until it was too late, that I would actually kill the queen. Maybe in their world, queens are never killed, only captured, only checkmated. I did something they didn't think an enemy would ever do."
"And when she died the others all died?"
"No, they just went stupid. The first ships we boarded, the buggers were still alive. Organically. But they didn't move, didn't respond to anything, even when our scientists vivisected some of them to see if we could learn a few more things about buggers. After a while they all died. No will. There's nothing in those little bodies when the queen is gone."
"Why don't they believe you?"
"Because we didn't find a queen."
"She got blown to pieces."
"Fortunes of war. Biology takes second place to survival. But some of them are coming around to my way of thinking. You can't live in this place without the evidence staring you in the face."
"What evidence is there in Eros?"
"Ender, look around you. Human beings didn't carve this place. We like taller ceilings, for one thing. This was the buggers' advance post in the First Invasion. They carved this place out before we even knew they were here. We're living in a bugger hive. But we already paid our rent. lt cost the marines a thousand lives to clear them out of these honeycombs, room by room. The buggers fought for every meter of it."
Now Ender understood why the rooms had always felt wrong to him. "I knew this wasn't a human place."
"This was the treasure trove. If they had known we would win that first war, they probably' would never have built this place. We learned gravity manipulation because they enhanced the gravity here. We learned efficient use of stellar energy because they blacked out this planet. In fact, that's how we discovered them. In a period of three days, Eros gradually disappeared from telescopes. We sent a tug to find out why. It found out. The tug transmitted its videos, including the buggers boarding and slaughtering the crew. It kept right on transmitting through the entire bugger examination of the boat. Not until they finally dismantled the entire tug did the transmissions stop. It was their blindness -- they never had to transmit anything by machine, and so with the crew dead, it didn't occur to them that anybody could be watching."
"Why did they kill the crew?"
"Why not? To them, losing a few crew members would be like clipping your nails. Nothing to get upset about. They probably thought they were routinely shutting down our communications by turning off the workers running the tug. Not murdering living, sentient beings with an independent genetic future. Murder's no big deal to them. Only queen-killing, really, is murder, because only queen-killing closes off a genetic path."
"So they didn't know what they were doing."
"Don't start apologizing for them, Ender. Just because they didn't know they were killing human beings doesn't mean they weren't killing human beings. We do have a right to defend ourselves as best we can, and the only way we found that works is killing the buggers before they kill us. Think of it this way. In all the bugger wars so far, they've killed thousands and thousands of living, thinking beings. And in all those wars, we've killed only one."
"If you hadn't killed the queen, Mazer, would we have lost the war?"
"I'd say the odds would have been three to two against us. I still think I could have trashed their fleet pretty badly before they burned us out. They have great response time and a lot of firepower, but we have a few advantages, too. Every single one of our ships contains an intelligent human being who's thinking on his own. Every one of us is capable of coming up with a brilliant solution to a problem. They can only come up with one brilliant solution at a time. The buggers think fast, but they aren't smart all over. Even when some incredibly timid and stupid commanders lost the major battles of the Second Invasion, some of their subordinates were able to do real damage to the bugger fleet."
"What about when our invasion reaches them? Will we just get the queen again?"
"The buggers didn't learn interstellar travel by being dumb. That was a strategy that could work only once. I suspect that we'll never get near a queen unless we actually make it to their home planet. After all, the queen doesn't have to be with them to direct a battle. The queen only has to be present to have little baby buggers. The Second invasion was a colony -- the queen was coming to populate the Earth. But this time -- no, that won't work. We'll have to beat them fleet by fleet. And because they have the resources of dozens of star systems to draw on, my guess is they'll outnumber us by a lot, in every battle."
Ender remembered his battle against two armies at once. And I thought they were cheating. When the real war begins, it'll be like that every time. And there won't be any gate I can go for.
"We've only got two things going for us, Ender. We don't have to aim particularly well. Our weapons have great spread."
"Then we aren't using the nuclear missiles from the First and Second Invasions?"
"Dr. Device is much more powerful. Nuclear weapons, after all, were weak enough to be used on Earth at one time. The Little Doctor could never be used on a planet. Still, I wish I'd had one during the Second Invasion."
"How does it work?"
"I don't know, not well enough to build one. At the focal point of two beams, it sets up a field in which molecules can't hold together anymore. Electrons can't be shared. How much physics do you know, at that level?"
"We spend most of our time on astrophysics, but I know enough to get the idea."
"The field spreads out in a sphere, but it gets weaker the farther it spreads. Except that where it actually runs into a lot of molecules, it gets stronger and starts over. The bigger the ship, the stronger the new field."
"So each time the field hits a ship, it sends out a new sphere--"
"And if their ships are too close together, it can set up a chain that wipes them all out. Then the field dies down, the molecules come back together, and where you had a ship, you now have a lump of dirt with a lot of iron molecules in it. No radioactivity, no mess. Just dirt. We may be able to trap them close together on the first battle, but they learn fast. They'll keep their distance from each other."
"So Dr. Device isn't a missile -- I can't shoot around corners.
"That's right. Missiles wouldn't do any good now. We learned a lot from them in the First Invasion, but they also learned from us -- how to set up the Ecstatic Shield, for instance."
"The Little Doctor penetrates the shield?"
"As if it weren't there. You can't see through the shield to aim and focus the beams, but since the generator of the Ecstatic Shield is always in the exact center, it isn't hard to figure it out."
"Why haven't I ever been trained with this?"
"You always have. We just let the computer tend to it for you. Your job is to get into a superior strategic position and choose a target. The shipboard computers are much better at aiming the Doctor than you are."
"Why is it called Dr. Device?"
"When it was developed, it was called a Molecular Detachment Device. M.D. Device."
Ender still didn't understand.
"M.D. The initials stand for Medical Doctor, too. M.D. Device, therefore Dr. Device. It was a joke." Ender didn't see what was funny about it.
They had changed the simulator. He could still control the perspective and the degree of detail, but there were no ship's controls anymore. Instead, it was a new panel of levers, and a small headset with earphones and a small microphone.
The technician who was waiting there quickly explained how to wear the headset.
"But how do I control the ships?" asked Ender.
Mazer explained. He wasn't going to control ships anymore. "You've reached the next phase of your training. You have experience in every level of strategy, but now it's time for you to concentrate on commanding an entire fleet. As you worked with toon leaders in Battle School, so now you will work with squadron leaders. You have been assigned three dozen such leaders to train. You must teach them intelligent tactics; you must learn their strengths and limitations; you must make them into a whole."
"When will they come here?"
"They're already in place in their own simulators. You will speak to them through the headset. The new levers on your control panel enable you to see from the perspective of any of your squadron leaders. This more closely duplicates the conditions you might encounter in a real battle, where you will only know what your ships can see."
"How can I work with squadron leaders I never see?"
"And why would you need to see them?"
"To know who they are, how they think--"
"You'll learn who they are and how they think from the way they work with the simulator. But even so, I think you won't be concerned. They're listening to you right now. Put on the headset so you can hear them."
Ender put on the headset.
"Salaam," said a whisper in his ears.
"Alai," said Ender.
"And me, the dwarf."
And Petra, and Dink; Crazy Tom, Shen, Hot Soup, Fly Molo, all the best students Ender had fought with or fought against, everyone that Ender had trusted in Battle School. "I didn't know you were here," he said, "I didn't know you were coming."
"They've been flogging us through the simulator for three months now," said Dink.
"You'll find that I'm by far the best tactician," said Petra. "Dink tries, but he has the mind of a child."
So they began working together, each squadron leader commanding individual pilots, and Ender commanding the squadron leaders. They learned many ways of working together, as the simulator forced them to try different situations. Sometimes the simulator gave them a larger fleet to work with; Ender set them up then in three or four toons that consisted of three or four squadrons each. Sometimes the simulator gave them a single starship with its twelve fighters, and he chose three squadron leaders with four fighters each.
It was pleasure; it was play. The computer-controlled enemy was none too bright, and they always won despite their mistakes, their miscommunications. But in the three weeks they practiced together, Ender came to know them very well. Dink, who deftly carried out instructions but was slow to improvise; Bean, who couldn't control large groups of ships effectively but could use only a few like a scalpel, reacting beautifully to anything the computer threw at him; Alai, who was almost as good a strategist as Ender and could be entrusted to do well with half a fleet and only vague instructions.
The better Ender knew them, the faster he could deploy them, the better he could use them. The simulator would display the situation on the screen. In that moment Ender learned for the first time what his own fleet would consist of and how the enemy fleet was deployed. It took him only a few minutes now to call for the squadron leaders that he needed, assign them to certain ships or groups of ships, and give them their assignments. Then, as the battle progressed, he would skip from one leader's point of view to another's, making suggestions and, occasionally, giving orders as the need arose. Since the others could only see their own battle perspective, he would sometimes give them orders that made no sense to them; but they, too, learned to trust Ender. If he told them to withdraw, they withdrew, knowing that either they were in an exposed position, or their withdrawal might entice the enemy into a weakened posture. They also knew that Ender trusted them to do as they judged best when he gave them no orders. If their style of fighting were not right for the situation they were placed in, Ender would not have chosen them for that assignment.
The trust was complete, the working of the fleet quick and responsive. And at the end of three weeks, Mazer showed him a replay of their most recent battle, only this time from the enemy's point of view.
"This is what he saw as you attacked. What does it remind you of? The quickness of response, for instance?"
"We look like a bugger fleet."
"You match them, Ender. You're as fast as they are. And here -- look at this."
Ender watched as all his squadrons moved at once, each responding to its own situation, all guided by Ender's overall command, but daring, improvising, feinting, attacking with an independence no bugger fleet had ever shown.
"The bugger hive-mind is very good, but it can only concentrate on a few things at once. All your squadrons can concentrate a keen intelligence on what they're doing, and what they've been assigned to do is also guided by a clever mind. So you see that you do have some advantages. Superior, though not irresistible, weaponry; comparable speed and greater available intelligence. These are your advantages. Your disadvantage is that you will always, always be outnumbered, and after each battle your enemy will learn more about you, how to fight you, and those changes will be put into effect instantly."
Ender waited for his conclusion.
"So, Ender, we will now begin your education. We have programmed the computer to simulate the kinds of situations we might expect in encounters with the enemy. We are using the movement patterns we saw in the Second Invasion. But instead of mindlessly following these same patterns, I will be controlling the enemy simulation. At first you will see easy situations that you are expected to win handily. Learn from them, because I will always be there, one step ahead of you, programming more difficult and advanced patterns into the computer so that your next battle is more difficult, so that you are pushed to the limit of your abilities."
"The time is short. You must learn as quickly as you can. When I gave myself to starship travel, just so I would still be alive when you appeared, my wife and children all died, and my grandchildren were my own age when I came back. I had nothing to say to them. I was cut off from all the people that I loved, everything I knew, living in this alien catacomb and forced to do nothing of importance but teach student after student, each one so hopeful, each one, ultimately, a weakling, a failure. I teach, I teach, but no one learns. You, too, have great promise, like so many students before you, but the seeds of failure may be in you, too. It's my job to find them, to destroy you if I can, and believe me, Ender, if you can be destroyed I can do it."
"So I'm not the first."
"No, of course you're not. But you're the last. If you don't learn, there'll be no time to find anyone else. So I have hope for you, only because you are the only one left to hope for."
"What about the others? My squadron leaders?"
"Which of them is fit to take your place?"
Ender had no answer, then.
"I am not a happy man, Ender. Humanity does not ask us to be happy. It merely asks us to be brilliant on its behalf. Survival first, then happiness as we can manage it. So, Ender, I hope you do not bore me during your training with complaints that you are not having fun. Take what pleasure you can in the interstices of your work, but your work is first, learning is first, winning is everything because without it there is nothing. When you can give me back my dead wife, Ender, then you can complain to me about what this education costs you."
"I wasn't trying to get out of anything."
"But you will, Ender. Because I am going to grind you down to dust, if I can. I'm going to hit you with everything I can imagine, and I will have no mercy, because when you face the buggers they will think of things I can't imagine, and compassion for human beings is impossible for them."
"You can't grind me down, Mazer."
"Oh, can't I?"
"Because I'm stronger than you."
Mazer smiled. "We'll see about that, Ender."
Mazer wakened him before morning; the clock said 0340, and Ender felt groggy as he padded along the corridor behind Mazer. "Early to bed and early to rise," Mazer intoned, "makes a man stupid and blind in the eyes."
He had been dreaming that buggers were vivisecting him. Only instead of cutting open his body, they were cutting up his memories and displaying them like holographs and trying to make sense of them. It was a very odd dream, and Ender couldn't easily shake loose of it, even as he walked through the tunnels to the simulator room. The buggers tormented him in his sleep, and Mazer wouldn't leave him alone when he was awake. Between the two of them he had no rest. Ender forced himself awake. Apparently Mazer meant it when he said he meant to break Ender down -- and forcing him to play when tired and sleepy was just the sort of cheap and easy trick Ender should have expected. Well, today it wouldn't work.
