"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."
"And beyond?"
"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, if 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?"
"Alai."
"Be honest."
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.
He got to the simulator and found his squadron leaders already on the wire, waiting for him. There was no enemy yet, so he divided them into two armies and began a mock battle, commanding both sides so he could control the test that each of his leaders was going through. They began slowly, but soon were vigorous and alert.
Then the simulator field went blank, the ships disappeared, and everything changed at once. At the near edge of the simulator field they could see the shapes, drawn in holographic light, of three starships from the human fleet. Each would have twelve fighters. The enemy, obviously aware of the human presence, had formed a globe with a single ship at the center. Ender was not fooled--it would not be a queen ship. The buggers outnumbered Ender's fighter force by two to one, but they were also grouped much closer together than they should have been--Dr. Device would be able to do much more damage than the enemy expected.
Ender selected one starship, made it blink in the simulator field, and spoke into the microphone. "Alai, this is yours; assign Petra and Vlad to the fighters as you wish." He assigned the other two starships with their fighter forces, except for one fighter from each starship that he reserved for Bean. "Slip the wall and get below them, Bean, unless they start chasing you--then run back to the reserves for safety. Otherwise, get in a place where I can call on you for quick results. Alai, form your force into a com-pact assault at one point in their globe. Don't fire until I tell you. This is maneuver only."
"This one's easy, Ender," Alai said.
"It's easy, so why not be careful? I'd like to do this without the loss of a single ship."
Ender grouped his reserves in two forces that shadowed Alai at a distance; Bean was already off the simulator, though Ender occasionally flipped to Bean's point of view to keep track of where he was.
It was Alai, however, who played the delicate game with the enemy. He was in a bullet-shaped formation, and probed the enemy globe. Wherever he came near, the bugger ships pulled back, as if to draw him in toward the ship in the center. Alai skimmed to the side; the bugger ships kept up with him, withdrawing wherever he was close, returning to the sphere pattern when he had passed.
Feint, withdraw, skim the globe to another point, withdraw again, feint again; and then Ender said, "Go on in, Alai."
His bullet started in, while he said to Ender, "You know they'll just let me through and surround me and eat me alive."
"Just ignore that ship in the middle."
"Whatever you say, boss."
Sure enough, the globe began to contract. Ender brought the reserves forward; the enemy ships concentrated on the side of the globe nearer the reserves. "Attack them there, where they're most concentrated," Ender said.
"This defies four thousand years of military history," said Alai, moving his fighters forward. "We're supposed to attack where we outnumber them."
"In this simulation they obviously don't know what our weapons can do. It'll only work once, but let's make it spectacular. Fire at will."
Alai did. The simulation responded beautifully: first one or two, then a dozen, then most of the enemy ships exploded in dazzling light as the field leapt from ship to ship in the tight formation. "Stay out of the way," Ender said.
The ships on the far side of the globe formation were not affected by the chain reaction, but it was a simple matter to hunt them d
own and destroy them. Bean took care of stragglers that tried to escape toward his end of space. The battle was over. It had been easier than most of their recent exercises.
Mazer shrugged when Ender told him so. "This is a simulation of a real invasion. There had to be one battle in which they didn't know what we could do. Now your work begins. Try not to be too arrogant about the victory. I'll give you the real challenges soon enough."
Ender practiced ten hours a day with his squadron leaders, but not all at once; he gave them a few hours in the afternoon to rest. Simulated battles under Mazer's supervision came every two or three days, and as Mazer had promised, they were never so easy again. The enemy quickly abandoned its attempt to surround Ender, and never again grouped its forces closely enough to allow a chain reaction. There was something new every time, something harder. Sometimes Ender had only a single starship and eight fighters; once the enemy dodged through an asteroid belt; sometimes the enemy left stationary traps, large installations that blew up if Ender brought one of his squadrons too close, often crippling or destroying some of Ender's ships. "You cannot absorb losses!" Mazer shouted at him after one battle. "When you get into a real battle you won't have the luxury of an infinite supply of computer-generated fighters. You'll have what you brought with you and nothing more. Now get used to fighting without unnecessary waste."
"It wasn't unnecessary waste," Ender said. "I can't win battles if I'm so terrified of losing a ship that I never take any risks."
Mazer smiled. "Excellent, Ender. You're beginning to learn. But in a real battle, you would have superior officers and, worst of all, civilians shouting those things at you. Now, if the enemy had been at all bright, they would have caught you here, and taken Tom's squadron." Together they went over the battle; in the next practice, Ender would show his leaders what Mazer had shown him, and they'd learn to cope with it the next time they saw it.
They thought they had been ready before, that they had worked smoothly together as a team. Now, though, having fought through real challenges together, they all began to trust each other more than ever, and battles became exhilarating. They told Ender that the ones who weren't actually playing would come into the simulator rooms and watch. Ender imagined what it would be like to have his friends there with him, cheering or laughing or gasping with apprehension; sometimes he thought it would be a great distraction, but other times he wished for it with all his heart. Even when he had spent his days lying out in the sunlight on a raft in a lake, he had not been so lonely. Mazer Rackham was his companion, was his teacher, but was not his friend.
He made no complaint, though. Mazer had told him there would be no pity, and his private unhappiness meant nothing to anyone. Most of the time it meant nothing even to Ender. He kept his mind on the game, trying to learn from the battles. And not just the particular lessons of that battle, but what the buggers might have done if they had been more clever, and how Ender would react if they did it in the future. He lived with past battles and future battles both, waking and sleeping, and he drove his squadron leaders with an intensity that occasionally provoked rebelliousness.
"You're too kind to us," said Alai one day. "Why don't you get annoyed with us for not being brilliant every moment of every practice. If you keep coddling us like this we'll think you like us."
Some of the others laughed into their microphones. Ender recognized the irony, of course, and answered with a long silence. When he finally spoke, he ignored Alai's complaint. "Again," he said, "and this time without self-pity." They did it again, and did it right.
But as their trust in Ender as a commander grew, their friendship, remembered from the Battle School days, gradually disappeared. It was to each other that they became close; it was with each other that they exchanged confidences. Ender was their teacher and commander, as distant from them as Mazer was from him, and as demanding.
They fought all the better for it. And Ender was not distracted from his work.
At least, not while he was awake. As he drifted off to sleep each night, it was with thoughts of the simulator playing through his mind. But in the night he thought of other things. Often he remembered the corpse of the Giant, decaying steadily; he did not remember it, though, in the pixels of the picture on his desk. Instead it was real, the faint odor of death still lingering near it. Things were changed in his dreams. The little village that had grown up between the Giant's ribs was composed of buggers now, and they saluted him gravely, like gladiators greeting Caesar before they died for his entertainment. He did not hate the buggers in his dream; and even though he knew that they had hidden their queen from him, he did not try to search for her. He always left the Giant's body quickly, and when he got to the playground, the children were always there, wolven and mocking; they wore faces that he knew. Sometimes Peter and sometimes Bonzo, sometimes Stilson and Bernard; just as often, though, the savage creatures were Alai and Shen, Dink and Petra; sometimes one of them would be Valentine, and in his dream he also shoved her under the water and waited for her to drown. She writhed in his hands, fought to come up, but at last was still. He dragged her out of the lake and onto the raft, where she lay with her face in the rictus of death. He screamed and wept over her, crying again and again that it was a game, a game, he was only playing!--
Then Mazer Rackham shook him awake. "You were calling out in your sleep," he said.
"Sorry," Ender said.
"Never mind. It's time for another battle."
Steadily the pace increased. There were usually two battles a day now, and Ender held practices to a minimum. He would use the time while the others rested to pore over the replays of past games, trying to spot his own weaknesses, trying to guess what would happen next. Sometimes he was fully prepared for the enemy's innovations; sometimes he was not.
"I think you're cheating," Ender told Mazer one day.
"Oh?"
"You can observe my practice sessions. You can see what I'm working on. You seem to be ready for everything I do."
"Most of what you see is computer simulations," Mazer said. "The computer is programmed to respond to your innovations only after you use them once in battle."
"Then the computer is cheating."
"You need to get more sleep, Ender."
But he could not sleep. He lay awake longer and longer each night, and his sleep was less restful. He woke too often in the night. Whether he was waking up to think more about the game or to escape from his dreams, he wasn't sure. It was as if someone rode him in his sleep, forcing him to wander through his worst memories, to live in them again as if they were real. Nights were so real that days began to seem dreamlike to him. He began to worry that he would not think clearly enough, that he would be too tired when he played. Always when the game began, the intensity of it awoke him, but if his mental abilities began to slip, he wondered, would he notice it?
And he seemed to be slipping. He never had a battle anymore in which he did not lose at least a few fighters. Several times the enemy was able to trick him into exposing more weakness than he meant to; other times the enemy was able to wear him down by attrition until his victory was as much a matter of luck as strategy. Mazer would go over the game with a look of contempt on his face. "Look at this," he would say. "You didn't have to do this." And Ender would return to practice with his leaders, trying to keep up their morale, but sometimes letting slip his disappointment with their weaknesses, the fact that they made mistakes.
"Sometimes we make mistakes," Petra whispered to him once. It was a plea for help.
"And sometimes we don't," Ender answered her. If she got help, it would not be from him. He would teach; let her find her friends among the others.
Then came a battle that nearly ended in disaster. Petra led her force too far; they were exposed, and she discovered it in a moment when Ender wasn't with her. In only a few moments she had lost all but two of her ships. Ender found her then, ordered her to move them in a certain direction; she didn't answer. There was no movement. And in
a moment those two fighters, too, would be lost.
Ender knew at once that he had pushed her too hard--because of her brilliance he had called on her to play far more often and under much more demanding circumstances than all but a few of the others. But he had no time now to worry about Petra, or to feel guilty about what he had done to her. He called on Crazy Tom to command the two remaining fighters, then went on, trying to salvage the battle; Petra had occupied a key position, and now all of Ender's strategy came apart. If the enemy had not been too eager and clumsy in exploiting their advantage, Ender would have lost. But Shen was able to catch a group of the enemy in too tight a formation and took them out with a single chain reaction. Crazy Tom brought his two surviving fighters in through the gap and caused havoc with the enemy, and though his ships and Shen's as well were finally destroyed, Fly Molo was able to mop up and complete the victory.
At the end of the battle, he could hear Petra crying out, trying to get a microphone, "Tell him I'm sorry, I was just so tired, I couldn't think, that was all, tell Ender I'm sorry."
She was not there for the next few practices, and when she did come back she was not as quick as she had been, not as daring. Much of what had made her a good commander was lost. Ender couldn't use her anymore, except in routine, closely supervised assignments. She was no fool. She knew what had happened. But she also knew that Ender had no other choice, and told him so.
The fact remained that she had broken, and she was far from being the weakest of his squad leaders. It was a warning--he could not press his commanders more than they could bear. Now, instead of using his leaders whenever he needed their skills, he had to keep in mind how often they had fought. He had to spell them off, which meant that sometimes he went into battle with commanders he trusted a little less. As he eased the pressure on them, he increased the pressure on himself.
Late one night he woke up in pain. There was blood on his pillow, the taste of blood in his mouth. His fingers were throbbing. He saw that in his sleep he had been gnawing on his own fist. The blood was still flowing smoothly. "Mazer!" he called. Rackham woke up and called at once for a doctor.
