Bolo! b-1

by David Weber

  The moving Bolo had passed four dead brigade mates in the last thirty kilometers, and it was not unwounded itself. Two of its starboard infinite repeaters had been blasted into mangled wreckage, energy weapon hits had sent molten splatters of duralloy weeping down its glacis plate to freeze like tears of pain, a third of its after sensor arrays had been stripped away by a near miss, and its forward starboard track shield was jammed in the lowered position, buckled and rent by enemy fire. Its turret bore the ID code 25/D-0098-ART and the unsheathed golden sword of a battalion commander, yet it was alone. Only one other unit of its battalion survived, and that unit lay ahead, beyond this death-choked valley. It was out there somewhere, moving even now through the trackless, waterless Badlands of the planet Camlan, and unit ART of the Line rumbled steadily down the valley to seek it out.

  * * *

  I interrogate my inertial navigation system as I approach my immediate objective. The INS is not the most efficient way to determine my position, but Camlan’s entire orbital network, including the recon and nav sats, as well as the communication relays, perished in the Enemy’s first strike, and the INS is adequate. I confirm my current coordinates and grind forward, leaving the valley at last.

  What lies before me was once a shallow cup of fertile green among the lava fields; now it is a blackened pit, and as my forward optical heads sweep the ruins of the town of Morville I feel the horror of Human mass death. There is no longer any need for haste, and I devote a full 6.007 seconds to the initial sweep. I anticipate no threats, but my on-site records will be invaluable to the court of inquiry I know will be convened to pass judgment upon my brigade. I am aware of my own fear of that court’s verdict and its implications for all Bolos, but I am a unit of the Line. This too, however bitter, is my duty, and I will not flinch from it.

  I have already observed the massive casualties C Company inflicted upon the Enemy in its fighting retreat up the Black Rock Valley. The Enemy’s vehicles are individually smaller than Bolos, ranging from 500.96 Standard Tons to no more than 4,982.07 Standard Tons, but heavily armed for their size. They are also manned, not self-aware, and he has lost many of them. Indeed, I estimate the aggregate tonnage of his losses in the Black Rock Valley alone as equivalent to at least three Bolo regiments. We have yet to determine this Enemy’s origins or the motives for his assault on Camlan, but the butchery to which he has willingly subjected his own personnel is sobering evidence of his determination… or fanaticism. Just as the blasted, body-strewn streets of Morville are ample proof of his ferocity.

  Seventy-one more wrecked Enemy vehicles choke the final approach to the town, and two far larger wrecks loom among them. I detect no transponder codes, and the wreckage of my brigade mates is so blasted that even I find it difficult to identify what remains, yet I know who they were. Unit XXV/D-1162-HNR and Unit XXV/D-0982-JSN of the Line have fought their last battle, loyal unto death to our Human creators.

  I reach out to them, hoping against hope that some whisper from the final refuge of their Survival Centers will answer my transmission, but there is no reply. Like the other Bolos I have passed this day, they are gone beyond recall, and the empty spots they once filled within the Total Systems Data Sharing net ache within me as I move slowly forward, alert still for any Enemy vehicles hiding among the wreckage. There are none. There are only the dead: the Enemy’s dead, and the six thousand Human dead, and my brothers who died knowing they had failed to save them.

  This is not the first time units of the Line have died, nor the first time they died in defeat. There is no shame in that, only sorrow, for we cannot always end in victory. Yet there is cause for shame here, for there are only two dead Bolos before me… and there should be three.

  Wind moans over the wreckage as I pick my way across the killing ground where my brothers’ fire shattered three Enemy attacks before the fourth overran them. Without the recon satellites there is no independent record of their final battle, but my own sensor data, combined with their final TSDS transmissions, allow me to deduce what passed here. I understand their fighting withdrawal down the Black Rock Valley and the savage artillery and missile barrages which flayed them as they fought. I grasp their final maneuvers from the patterns of wreckage, recognize the way the Enemy crowded in upon them as his steady pounding crippled their weapons. I see the final positions they assumed, standing at last against the Enemy’s fire because they could no longer retreat without abandoning Morville.

  And I see the third position from which a single Bolo did retreat, falling back, fleeing into the very heart of the town he was duty bound to defend. I track his course by the crushed and shattered wreckage of buildings and see the bodies of the Camlan Militia who died as he fled, fighting with their man-portable weapons against an Enemy who could destroy 13,000-ton Bolos. There are many Enemy wrecks along his course, clear evidence of how desperately the Militia opposed the invaders’ advance even as the Bolo abandoned Morville, fleeing north into the Badlands where the Enemy’s less capable vehicles could not pursue, and I know who left those Humans to die. Unit XXV/D-0103-LNC of the Line, C Company’s command Bolo, my creche mate and battle companion and my most trusted company commander. I have fought beside him many times, known his utter reliability in the face of the Enemy, but I know him no longer, for what he has done is unforgivable. He is the first, the only, Bolo ever to desert in the face of the Enemy, abandoning those we are bound to protect to the death and beyond.

  For the first time in the history of the Dinochrome Brigade, we know shame. And fear. As LNC, I am a Mark XXV, Model D, the first production model Bolo to be allowed complete, permanent self-awareness, and LNC’s actions attack the very foundation of the decision which made us fully self-realized personalities. We have repeatedly demonstrated how much more effective our awareness makes us in battle, yet our freedom of action makes us unlike any previous units of the Brigade. We are truly autonomous… and if one of us can choose to flee-if one of us can succumb to cowardice-perhaps all of us can.

  I complete my survey of the site in 4.307 minutes. There are no survivors, Enemy, Human, or Bolo, in Morville, and I report my grim confirmation to my Brigade Commander and to my surviving brothers and sisters. The Enemy’s surprise attack, coupled with our subsequent losses in combat, have reduced Sixth Brigade to only fourteen units, and our acting Brigade Commander is Lieutenant Kestrel, the most junior-and sole surviving-Human of our command staff. The Commander is only twenty-four Standard Years of age, on her first posting to an active duty brigade, and the exhaustion in her voice is terrible to hear. Yet she has done her duty superbly, and I feel only shame and bitter, bitter guilt that I must impose this additional decision upon her. I taste the matching shame and guilt of the surviving handful of my brothers and sisters over the TSDS, but none of them can assist me. The Enemy is in full retreat to his spaceheads, yet the fighting continues at a furious pace. No other Bolos can be diverted from it until victory is assured, and so I alone have come to investigate and confirm the unbelievable events here, for I am the commander of LNC’s battalion. It is up to me to do what must be done.

  “All right, Arthur,” Lieutenant Kestrel says finally. “We’ve got the situation in hand here, and Admiral Shigematsu’s last subspace flash puts Ninth Fleet just thirty-five hours out. We can hold the bastards without you. Go do what you have to.”

  “Yes, Commander,” I reply softly, and pivot on my tracks, turning my prow to the north, and follow LNC’s trail into the lava fields.

  * * *

  Unit XXV/D-0103-LNC of the Line churned across the merciless terrain. Both outboard port tracks had been blown away, and bare road wheels groaned in protest as they chewed through rock and gritty soil. His armored hull was gouged and torn, his starboard infinite repeaters and anti-personnel clusters a tangled mass of ruin, but his builders had designed him well. His core war hull had been breached in three places, wreaking havoc among many of his internal systems, yet his main armament remained intact… and he knew he was pursued.<

  LNC paused, checking his position against his INS and the maps in Main Memory. It was a sign of his brutal damage that he required almost twenty full seconds to determine his location, and then he altered course. The depression was more a crevasse than a valley-a sunken trough, barely half again the width of his hull, that plunged deep below the level of the fissured lava fields. It would offer LNC cover as he made his painful way towards the distant Avalon Mountains, and a cloud of dust wisped away on the icy winter wind as he vanished into the shadowed cleft.

  I try to deduce LNC’s objective, assuming that he has one beyond simple flight, but the task is beyond me. I can extrapolate the decisions of a rational foe, yet the process requires some understanding of his motives, and I no longer understand LNC’s motives. I replay the final TSDS transmission from XXV/D-1162-HNR and experience once more the sensation a Human might define as a chill of horror as LNC suddenly withdraws from the data net. I share HNR’s attempt to reestablish the net, feel LNC’s savage rejection of all communication. And then I watch through HNR’s sensors as LNC abandons his position, wheeling back towards Morville while Enemy fire bellows and thunders about him… and I experience HNR’s final shock as his own company commander responds to his repeated queries by pouring Hellbore fire into his unprotected rear.

  LNC’s actions are impossible, yet the data are irrefutable. He has not only fled the Enemy but killed his own brigade mate, and his refusal even to acknowledge communication attempts is absolute. That, too, is impossible. Any Bolo must respond to the priority com frequencies, yet LNC does not. He has not only committed mutiny and treason but refused to hear any message from Lieutenant Kestrel, as he might reject an Enemy communications seizure attempt. How any Bolo could ignore his own Brigade Commander is beyond my comprehension, yet he has, and because there is no longer any communication interface at all, Lieutenant Kestrel cannot even access the Total Systems Override Program to shut him down.

  None of my models or extrapolations can suggest a decision matrix which could generate such actions on LNC’s part. But perhaps that is the point. Perhaps there is no decision matrix, only panic. Yet if that is true, what will he do when the panic passes-if it passes? Surely he must realize his own fate is sealed, whatever the outcome of the Enemy’s attack. How can I anticipate rational decisions from him under such circumstances?

  I grind up another slope in his tracks. He has altered course once more, swinging west, and I consult my internal maps. His base course has been towards the Avalon Mountains, and I note the low ground to the west. He is no longer on a least-time heading for the mountains, but the long, deep valley will take him there eventually. It will also afford him excellent cover and numerous ambush positions, and I am tempted to cut cross-country and head him off. But if I do that and he is not, in fact, headed for the mountains, I may lose him. He cannot hide indefinitely, yet my shame and grief-and sense of betrayal-will not tolerate delay, and I know from HNR’s last transmission that LNC’s damage is much worse than my own.

  I consider options and alternatives for.0089 seconds, and then head down the slope in his wake.

  Unit LNC slowed as the seismic sensors he’d deployed along his back trail reported the ground shocks of a pursuing vehicle in the thirteen-thousand-ton range. He’d known pursuit would come, yet he’d hoped for a greater head start, for he had hundreds of kilometers still to go, and his damaged suspension reduced his best sustained speed to barely forty-six kilometers per hour. He must reach the Avalons. No Enemy could be permitted to stop him, yet the remote sensors made it clear the Enemy which now pursued him was faster than he.

  But there were ways to slow his hunter, and he deployed another pair of seismic sensors while his optical heads and sonar considered the fissured rock strata around him.

  I am gaining on LNC. His track damage must be worse than I had believed, and the faint emissions of his power plants come to me from ahead. I know it is hopeless, yet even now I cannot truly believe he is totally lost to all he once was, and so I activate the TSDS once more and broadcast strongly on C Company’s frequencies, begging him to respond.

  Unit LNC picked up the powerful transmissions and felt contempt for the one who sent them. Could his pursuer truly believe he would fall for such an obvious ploy? That he would respond, give away his position, possibly even accept communication and allow access to his core programming? LNC recognized the communications protocols, but that meant nothing. LNC no longer had allies, friends, war brothers or sisters. There was only the Enemy… and the Avalon Mountains which drew so slowly, agonizingly closer.

  But even as LNC ignored the communications attempt, he was monitoring the seismic sensors he’d deployed. He matched the position those sensors reported against his own terrain maps and sent the execution code.

  Demolition charges roar, the powerful explosions like thunder in the restricted cleft. I understand their purpose instantly, yet there is no time to evade as the cliffs about me shudder. It is a trap. The passage has narrowed to little more than the width of my own combat chassis, and LNC has mined the sheer walls on either hand.

  I throw maximum power to my tracks, fighting to speed clear, but hundreds of thousands of tons of rock are in motion, cascading down upon me. My kinetic battle screen could never resist such massive weights, and I deactivate it to prevent its burnout as the artificial avalanche crashes over me. Pain sensors flare as boulders batter my flanks. Power train components scream in protest as many times my own weight in crushed rock and shifting earth sweep over me, and I am forced to shut them down, as well. I can only ride out the cataclysm, and I take grim note that LNC has lost none of his cunning in his cowardice.

  It takes 4.761 minutes for the avalanche to complete my immobilization and another 6.992 minutes before the last boulder slams to rest. I have lost 14.37% percent more of my sensors, and most of those which remain are buried under meters of debris. But a quick diagnostic check reveals that no core systems have suffered damage, and sonar pulses probe the tons of broken rock which overlay me, generating a chart of my overburden.

  All is not lost. LNC’s trap has immobilized me, but only temporarily. I calculate that I can work clear of the debris in not more than 71.650 minutes, and jammed boulders shift as I begin to rock back and forth on my tracks.

  LNC’s remote sensors reported the seismic echoes of his pursuer’s efforts to dig free. For a long moment-almost.3037 seconds-he considered turning to engage his immobilized foe, but only for a moment. LNC’s Hellbore remained operational, but he’d expended ninety-six percent of his depletable munitions, his starboard infinite repeaters were completely inoperable, and his command and control systems’ efficiency was badly degraded. Even his Battle Reflex functioned only erratically, and he knew his reactions were slow, without the flashing certainty which had always been his. His seismic sensors could give no detailed information on his hunter, yet his Enemy was almost certainly more combat worthy than he, and his trap was unlikely to have inflicted decisive damage.

  No. It was the mountains which mattered, the green, fertile mountains, and LNC dared not risk his destruction before he reached them. And so he resisted the temptation to turn at bay and ground steadily onward through the frozen, waterless Badlands on tracks and naked road wheels.

  I work my way free at last. Dirt and broken rock shower from my flanks as my tracks heave me up out of the rubble-clogged slot. More dirt and boulders crown my war hull and block Number Three and Number Fourteen Optical Heads, yet I remain operational at 89.051% of base capacity, and I have learned. The detonation of his demolition charges was LNC’s response to my effort to communicate. The brother who fought at my side for twenty-one Standard Years truly is no more. All that remains is the coward, the deserter, the betrayer of trust who will stop at nothing to preserve himself. I will not forget again-and I can no longer deceive myself into believing he can be convinced to give himself up. The only gift I can offer him now is his destruction, and I throw additional power to my tracks as I g
o in pursuit to give it to him.

  * * *

  LNC’s inboard forward port suspension screamed in protest as the damaged track block parted at last. The fleeing Bolo shuddered as he ran forward off the track, leaving it twisted and trampled in his wake. The fresh damage slowed him still further, and he staggered drunkenly as his unbalanced suspension sought to betray him. Yet he forced himself back onto his original heading, and his deployed remotes told him the Enemy was gaining once more. His turret swiveled, training his Hellbore directly astern, and he poured still more power to his remaining tracks. Drive components heated dangerously under his abuse, but the mountains were closer.

  I begin picking up LNC’s emissions once more, despite the twisting confines of the valley. They remain too faint to provide an accurate position fix, but they give me a general bearing, and an armored hatch opens as I deploy one of my few remaining reconnaissance drones.
