David Weber - Bolo!

There is only one possibility. I will proceed at maximum speed to the end of this valley. According to my maps, I should reach its northern end at least 42.35 minutes before he can attain the cover of the mountains, and I will be between him and his refuge. I will be able to move towards him, using my remaining forward sensors to search for and find him, and if his Hellbore is indeed permanently disabled, I will destroy him with ease. My plan is not without risks, for my damaged sensors can no longer sweep the tops of the valley walls effectively. If his Hellbore can be restored to operation, he will be able to choose his firing position with impunity, and I will be helpless before his attack. But risk or no, it is my only option, and if I move rapidly enough, I may well outrun him and get beyond engagement range before he can make repairs.

LNC watched helplessly as the Enemy reemerged from hiding and sped up the narrow valley. He understood the Enemy’s logic, and the loss of his Hellbore left him unable to defeat it. If he continued towards the Avalons, he would be destroyed, yet he had no choice, and he turned away from the valley, naked road wheels screaming in protest as he battered his way across the lava fields.

I have reached the end of the valley, and I emerge into the foothills of the Avalon Range and alter course to the west. I climb the nearest hill, exposing only my turret and forward sensor arrays over its crest, and begin the most careful sweep of which I remain capable.

LNC’s passive sensors detected the whispering lash of radar and he knew he’d lost the race. The Enemy was ahead of him, waiting, and he ground to a halt. His computer core had suffered additional shock damage when the disintegrating ridge crest smashed into him, and his thoughts were slow. It took him almost thirteen seconds to realize what he must do. The only thing he could do now.

“Tommy?”

Thomas Mallory looked up from where he crouched on the floor of the packed compartment. His eight-year-old sister had sobbed herself out of tears at last, and she huddled against his side in the protective circle of his arm. But Thomas Mallory had learned too much about the limits of protectiveness. At fifteen, he was the oldest person in the compartment, and he knew what many of the others had not yet realized-that they would never see their parents again, for the fifty-one of them were the sole survivors of Morville.

“Tommy?” the slurred voice said once more, and Thomas cleared his throat.

“Yes?” He heard the quaver in his own voice, but he made himself speak loudly. Despite the air filtration systems, the compartment stank of ozone, explosives, and burning organic compounds. He’d felt the terrible concussions of combat and knew the vehicle in whose protective belly he sat was savagely wounded, and he was no longer certain how efficient its audio pickups might be.

“I have failed in my mission, Tommy,” the voice said. “The Enemy has cut us off from our objective.”

“What enemy?” Thomas demanded. “Who are they, Lance? Why are they doing this?”

“They are doing it because they are the Enemy,” the voice replied.

“But there must be a reason!” Thomas cried with all the anguish of a fifteen-year-old heart.

“They are the Enemy,” the voice repeated in that eerie, slurred tone. “It is the Enemy’s function to destroy… to destroy… to dest-” The voice chopped off, and Thomas swallowed. Lance’s responses were becoming increasingly less lucid, wandering into repetitive loops that sometimes faded into silence and other times, as now, cut off abruptly, and Thomas Mallory had learned about mortality. Even Bolos could perish, and somehow he knew Lance was dying by centimeters even as he struggled to complete his mission.

“They are the Enemy,” Lance resumed, and the electronic voice was higher and tauter. “There is always the Enemy. The Enemy must be defeated. The Enemy must be destroyed. The Enemy-” Again the voice died with the sharpness of an axe blow, and Thomas bit his lip and hugged his sister tight. Endless seconds of silence oozed past, broken only by the whimpers and weeping of the younger children, until Thomas could stand it no longer.

“Lance?” he said hoarsely.

“I am here, Tommy.” The voice was stronger this time, and calmer.

“W-What do we do?” Thomas asked.

“There is only one option.” A cargo compartment hissed open to reveal a backpack military com unit and an all-terrain survival kit. Thomas had never used a military com, but he knew it was preset to the Dinochrome Brigade’s frequencies. “Please take the kit and com unit,” the voice said.

“All right.” Thomas eased his arm from around his sister and lifted the backpack from the compartment. It was much lighter than he’d expected, and he slipped his arms through the straps and settled it on his back, then tugged the survival kit out as well.

“Thank you,” the slurred voice said. “Now, here is what you must do, Tommy-”

My questing sensors detect him at last. He is moving slowly, coming in along yet another valley. This one is shorter and shallower, barely deep enough to hide him from my fire, and I trace its course along my maps. He must emerge from it approximately 12.98 kilometers to the southwest of my present position, and I grind into motion once more. I will enter the valley from the north and sweep along it until we meet, and then I will kill him.

Thomas Mallory crouched on the hilltop. It hadn’t been hard to make the younger kids hide-not after the horrors they’d seen in Morville. But Thomas couldn’t join them. He had to be here, where he could see the end, for someone had to see it. Someone had to be there, to know how fifty-one children had been saved from death… and to witness the price their dying savior had paid for them.

Distance blurred details, hiding Lance’s dreadful damages as he ground steadily up the valley, but Thomas’s eyes narrowed as he saw the cloud of dust coming to meet him. Tears burned like ice on his cheeks in the sub-zero wind, and he scrubbed at them angrily. Lance deserved those tears, but Thomas couldn’t let the other kids see them. There was little enough chance that they could survive a single Camlan winter night, even in the mountains, where they would at least have water, fuel, and the means to build some sort of shelter. But it was the only chance Lance had been able to give them, and Thomas would not show weakness before the children he was now responsible for driving and goading into surviving until someone came to rescue them. Would not betray the trust Lance had bestowed upon him.

The oncoming dust grew thicker, and he raised the electronic binoculars, gazing through them for his first sight of the enemy. He adjusted their focus as an iodine-colored turret moved beyond a saddle of hills. Lance couldn’t see it from his lower vantage point, but Thomas could, and his face went suddenly paper-white. He stared for one more moment, then grabbed for the com unit’s microphone.

“No, Lance! Don’t-don’t! It’s not the enemy-it’s another Bolo!”

The Human voice cracks with strain as it burns suddenly over the command channel, and confusion whips through me. The transmitter is close-very close-and that is not possible. Nor do I recognize the voice, and that also is impossible. I start to reply, but before I can, another voice comes over the same channel.

“Cease transmission,” it says. “Do not reveal your location.”

This time I know the voice, yet I have never heard it speak so. It has lost its crispness, its sureness. It is the voice of one on the brink of madness, a voice crushed and harrowed by pain and despair and a purpose that goes beyond obsession.

“Lance,” the Human voice-a young, male Human voice-sobs. “Please, Lance! It’s another Bolo! It really is!”
