Ender destroys bugger homeworld (Third Invasion)

Ender Wiggin's destruction of the bugger homeworld is the pivotal event of the Third Invasion, the moment when the child commander, believing he is playing a final simulation, actually obliterates an entire alien species. The battle, presented to Ender as his final examination at Command School, is in truth the real war against the buggers, and his victory—achieved by breaking every rule of the game—ends the conflict but leaves him morally shattered. This act transforms Ender from a brilliant military prodigy into a reluctant genocidaire, a burden that defines his subsequent life as the Speaker for the Dead and his quest for understanding and redemption.

The Setup: A Final Examination

Ender arrives at the simulator room on the asteroid Eros, exhausted and hollowed by months of grueling training under Mazer Rackham. He has been pushed to the brink of physical and mental collapse, suffering from nightmares, self-inflicted wounds, and a growing despair. Mazer tells him that this is his final examination, a test of his ability to meet challenges he has never seen before, and that if he wins, he will be the first student to do so. The room is filled with observers, including Colonel Graff and Major Anderson, who watch silently as Ender prepares for what he believes is a game.

The enemy formation appears, and Ender's weariness turns to despair. The bugger fleet outnumbers him a thousand to one, the simulator glowing green with their ships. His own fleet consists of twenty old-fashioned starships, each with only four fighters—eighty fighters against at least five thousand, perhaps ten thousand enemy ships. The planet is at the far edge of the field, and Ender realizes that the odds are impossibly stacked against him. He hears his squadron leaders breathing heavily, and a quiet curse from one of the observers behind him. It is clear that this is not a fair test, and Ender feels that all his efforts have been in vain.

The Decision to Cheat

As Ender contemplates the hopeless situation, he remembers his last battle in Battle School, when the teachers put two armies against him. In that battle, he won by ignoring the enemy and moving against the enemy's gate. Bean's voice comes over the headset, saying, "Remember, the enemy's gate is down," and the other squadron leaders laugh. Ender also laughs, realizing that the adults are taking the game too seriously, and that he can cheat just as they have cheated him. He decides that if he breaks the rules, they will never let him be a commander, and he will never have to play a game again. That, he thinks, is victory.

Ender whispers commands to his squadron leaders, grouping his fleet into a thick projectile aimed at the nearest enemy formation. The enemy welcomes him in, trying to entrap him, but Ender dodges and weaves, always moving closer to the planet. Finally, his formation bursts into chaos, his fighters seeming to follow no plan at all, firing at random and working their way into hopeless individual paths. After a few minutes, a dozen of the remaining fighters form again, now on the far side of one of the enemy's most formidable groups, having passed through with terrible losses. They have covered more than half the distance to the planet.

The Destruction of the Planet

Ender's tiny fleet darts this way and that, sending out two or three fighters as if to attack, then bringing them back. The enemy closes in, drawing in ships and formations from all sides, concentrating beyond Ender to prevent his escape. Ender whispers a command, and his ships drop like rocks toward the planet's surface, focusing their Little Doctors on the planet itself. Seven of his fighters are blown away, but it is all a gamble now. As the surface of the planet begins to bubble and explode, Ender takes his hands off the controls and watches. Within three seconds, the entire planet bursts apart, becoming a sphere of bright dust hurtling outward. The field spreads, taking apart every ship in its path, erupting each into a dot of light. Only at the very periphery does the field weaken, leaving two or three enemy ships drifting away. Where the vast enemy fleet and the planet had been, there is nothing meaningful—only a lump of dirt, glowing hot and spinning, much smaller than the world had been before.

The Revelation: It Was Real

Ender takes off his headphones, filled with the cheers of his squadron leaders, and only then realizes that the room is filled with noise. Men in uniform are hugging each other, laughing, shouting; others are weeping or kneeling in prayer. Colonel Graff, tears streaming down his face, embraces Ender and whispers, "Thank you, thank you Ender. Thank God for you, Ender." Mazer Rackham comes through the crowd and holds out his hand, saying, "You made the hard choice, boy. All or nothing. End them or end us. But heaven knows there was no other way you could have done it. Congratulations. You beat them, and it's all over."

Ender does not understand. He says, "I beat you." Mazer laughs and tells him, "Ender, you never played me. You never played a game since I became your enemy." He explains that for the past few months, Ender has been the battle commander of their fleets, and this was the Third Invasion. There were no games; the battles were real, and the only enemy he fought was the buggers. He won every battle, and today he fought them at their home world, where the queen was, all the queens from all their colonies, and he destroyed them completely. They will never attack again. Ender's mind is too tired to cope with it all. He walks through the crowd, dodging their congratulations, and when he gets to his room, he strips off his clothes, climbs into bed, and sleeps.

Aftermath: The Weight of Genocide

When Ender wakes, Graff and Rackham tell him that the videos of the battle have been playing on Earth, and he is a hero, voted the highest medal by every government. But Ender is not triumphant. He asks, "I killed them all, didn't I?" and when they confirm it, he says, "All their queens. So I killed all their children, all of everything." He grabs Mazer's uniform and cries, "I didn't want to kill them all. I didn't want to kill anybody! I'm not a killer! You didn't want me, you bastards, you wanted Peter, but you made me do it, you tricked me into it!" Graff explains that it had to be a trick, because a commander with enough empathy to understand the buggers could never knowingly commit genocide. Ender is left with the burden of his actions, and in the days that follow, he dreams of the destruction over and over, seeing the buggers explode and turn to light, and the queen surrounded by infants with the faces of his friends. He is haunted by the knowledge that he has killed billions, and this guilt shapes his decision to become the Speaker for the Dead, to tell the buggers' story and seek forgiveness.
