Bean thought back to those vids that Ender had watched over and over in Battle School--all the propaganda film of the Second Invasion.
They never showed the battle because there wasn't one. Nor did Mazer Rackham command a strike force with a brilliant strategy. Mazer Rackham hit a single ship and the war was over. That's why there's no video of hand-to-hand combat. Mazer Rackham killed the queen. And now he expects the Buggers to show a central ship as a decoy, because that's how we won last time.
Kill the queen, and all the Buggers are defenseless. Mindless. That's what the vids meant. Ender knows that, but he also knows that the Buggers know that we know it, so he doesn't fall for their sucker bait.
The second thing that Ender knew and they didn't was the use of a weapon that hadn't been in any of their simulations till this first test. Ender called it "Dr. Device" and then said nothing more about it--until he ordered Alai to use it where the enemy fleet was most concentrated. To their surprise, the thing set off a chain reaction that leapt from ship to ship, until all but the most outlying Formic ships were destroyed. And it was an easy matter to mop up those stragglers. The playing field was clear when they finished.
"Why was their strategy so stupid?" asked Bean.
"That's what I was wondering," said Ender. "But we didn't lose a ship, so that's OK."
Later, Ender told them what Mazer said--they were simulating a whole invasion sequence, and so he was taking the simulated enemy through a learning curve. "Next time they'll have learned. It won't be so easy."
Bean heard that and it filled him with alarm. An invasion sequence? Why a scenario like that? Why not warmups before a single battle?
Because the Buggers have more than one world, thought Bean. Of course they do. They found Earth and expected to turn it into yet another colony, just as they've done before.
We have more than one fleet. One for each Formic world.
And the reason they can learn from battle to battle is because they, too, have faster-than-light communication across interstellar space.
All of Bean's guesses were confirmed. He also knew the secret behind these tests. Mazer Rackham wasn't commanding a simulated Bugger fleet. It was a real battle, and Rackham's only function was to watch how it flowed and then coach Ender afterward on what the enemy strategies meant and how to counter them in future.
That was why they were giving most of their commands orally. They were being transmitted to real crews of real ships who followed their orders and fought real battles. Any ship we lose, thought Bean, means that grown men and women have died. Any carelessness on our part takes lives. Yet they don't tell us this precisely because we can't afford to be burdened with that knowledge. In wartime, commanders have always had to learn the concept of "acceptable losses." But those who keep their humanity never really accept the idea of acceptability, Bean understood that. It gnaws at them. So they protect us child-soldiers by keeping us convinced that it's only games and tests.
Therefore I can't let on to anyone that I do know. Therefore I must accept the losses without a word, without a visible qualm. I must try to block out of my mind the people who will die from our boldness, whose sacrifice is not of a mere counter in a game, but of their lives.
The "tests" came every few days, and each battle lasted longer. Alai joked that they ought to be fitted with diapers so they didn't have to be distracted when their bladder got full during a battle. Next day, they were fitted out with catheters. It was Crazy Tom who put a stop to that. "Come on, just get us a jar to pee in. We can't play this game with something hanging off our dicks." Jars it was, after that. Bean never heard of anyone using one, though. And though he wondered what they provided for Petra, no one ever had the courage to brave her wrath by asking.
Bean began to notice some of Ender's mistakes pretty early on. For one thing, Ender was relying too much on Petra. She always got command of the core force, watching a hundred different things at once, so that Ender could concentrate on the feints, the ploys, the tricks. Couldn't Ender see that Petra, a perfectionist, was getting eaten alive by guilt and shame over every mistake she made? He was so good with people, and yet he seemed to think she was really tough, instead of realizing that toughness was an act she put on to hide her intense anxiety. Every mistake weighed on her. She wasn't sleeping well, and it showed up as she got more and more fatigued during battles.
But then, maybe the reason Ender didn't realize what he was doing to her was that he, too, was tired. So were all of them. Fading a little under the pressure, and sometimes a lot. Getting more fatigued, more error-prone as the tests got harder, as the odds got longer.
Because the battles were harder with each new "test," Ender was forced to leave more and more decisions up to others. Instead of smoothly carrying out Ender's detailed commands, the squadron leaders had more and more of the battle to carry on their own shoulders. For long sequences, Ender was too busy in one part of the battle to give new orders in another. The squadron leaders who were affected began to use crosstalk to determine their tactics until Ender noticed them again. And Bean was grateful to find that, while Ender never gave him the interesting assignments, some of the others talked to him when Ender's attention was elsewhere. Crazy Tom and Hot Soup came up with their own plans, but they routinely ran them past Bean. And since, in each battle, he was spending half his attention observing and analyzing Ender's plan, Bean was able to tell them, with pretty good accuracy, what they should do to help make the overall plan work out. Now and then Ender praised Tom or Soup for decisions that came from Bean's advice. It was the closest thing to praise that Bean heard.
The other toon leaders and the older kids simply didn't turn to Bean at all. He understood why; they must have resented it greatly when the teachers placed Bean above them during the time before Ender was brought in. Now that they had their true commander, they were never again going to do anything that smacked of subservience to Bean. He understood--but that didn't keep it from stinging.
Whether or not they wanted him to oversee their work, whether or not his feelings were hurt, that was still his assignment and he was determined never to be caught unprepared. As the pressure became more and more intense, as they became wearier and wearier, more irritable with each other, less generous in their assessment of each other's work, Bean became all the more attentive because the chances of error were all the greater.
One day Petra fell asleep during battle. She had let her force drift too far into a vulnerable position, and the enemy took advantage, tearing her squadron to bits. Why didn't she give the order to fall back? Worse yet, Ender didn't notice soon enough, either. It was Bean who told him: Something's wrong with Petra.
Ender called out to her. She didn't answer. Ender flipped control of her two remaining ships to Crazy Tom and then tried to salvage the overall battle. Petra had, as usual, occupied the core position, and the loss of most of her large squadron was a devastating blow. Only because the enemy was overconfident during mop-up was Ender able to lay a couple of traps and regain the initiative. He won, but with heavy losses.
Petra apparently woke up near the end of the battle and found her controls cut off, with no voice until it was all over. Then her microphone came on again and they could hear her crying, "I'm sorry, I'm sorry. Tell Ender I'm sorry, he can't hear me, I'm so sorry . . ."
Bean got to her before she could return to her room. She was staggering along the tunnel, leaning against the wall and crying, using her hands to find her way because she couldn't see through her tears. Bean came up and touched her. She shrugged off his hand.
"Petra," said Bean. "Fatigue is fatigue. You can't stay awake when your brain shuts down."
"It was my brain that shut down! You don't know how that feels because you're always so smart you could do all our jobs and play chess while you're doing it!"
"Petra, he was relying on you too much, he never gave you a break--"
"He doesn't take breaks either, and I don't see him--"
"Yes you do. It was obvious there was something wrong with your squadron for several seconds before somebody called his attention to it. And even then, he tried to rouse you before assigning control to somebody else. If he'd acted faster you would have had six ships left, not just two."
"You pointed it out to him. You were watching me. Checking up on me."
