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 go 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.

LNC detected the drone as it came sweeping up the valley. His anti-air defenses, badly damaged at Morville, were unable to engage, but his massive ninety-centimeter Hellbore rose like a striking serpent, and a bolt of plasma fit to destroy even another Bolo howled from its muzzle.

My drone has been destroyed, but the manner of its destruction tells me much. LNC would not have engaged it with his main battery if his anti-air systems remained effective, and that means there is a chink in his defenses. I have expended my supply of fusion warheads against the invaders, but I retain 37.961% of my conventional warhead missile load, and if his air defenses have been seriously degraded, a saturation bombardment may overwhelm his battle screen. Even without battle screen, chemical explosives would be unlikely to significantly injure an undamaged Bolo, of course, but LNC is not undamaged.

I consider the point at which my drone was destroyed and generate a new search pattern. I lock the pattern in, and the drone hatches open once more. Twenty-four fresh drones-82.75% of my remaining total-streak upward, and I open my VLS missile cell hatches, as well.

The drones came screaming north. They didn’t come in slowly this time, for they were no longer simply searching for LNC. This time they already knew his approximate location, and their sole task was to confirm it for the Enemy’s fire control.

But LNC had known they would be coming. He had already pivoted sharply on his remaining tracks and halted, angled across the valley to clear his intact port infinite repeaters’ field of fire, and heavy ion bolts shrieked to meet the drones. His surviving slug-throwers and laser clusters added their fury, and the drones blew apart as if they’d run headlong into a wall. Yet effective as his fire was, it was less effective than his crippled air defense systems would have been, and one drone-just one-survived long enough to report his exact position.

I am surprised by the efficiency of LNC’s fire, but my drones have accomplished their mission. More, they have provided my first visual observation of his damages, and I am shocked by their severity. It seems impossible that he can still be capable of movement, far less accurately directed fire, and despite his cowardice and treason, I feel a stab of sympathy for the agony which must be lashing him from his pain receptors. Yet he clearly remains combat capable, despite his hideous wounds, and I feed his coordinates to my missiles. I take.00037 seconds to confirm my targeting solution, and then I fire.

Flame fountained from the shadowed recesses of the deep valley as the missile salvos rose and howled north, homing on their target. Most of ART’s birds came in on conventional, high-trajectory courses, but a third of them came in low, relying on terrain avoidance radar to navigate straight up the slot of the valley. The hurricane of his fire slashed in on widely separated bearings, and LNC’s crippled active defenses were insufficient to intercept it all.

ART emptied his VLS cells, throwing every remaining warhead at his treasonous brigade mate. Just under four hundred missiles launched in less than ninety seconds, and LNC writhed as scores of them got through his interception envelope. They pounded his battle screen, ripped and tore at lacerated armor, and pain receptors shrieked as fresh damage bit into his wounded war hull. Half his remaining infinite repeaters were blown away, still more sensor capability was blotted out, and his thirteen-thousand-ton bulk shuddered and shook under the merciless bombardment.

Yet he survived. The last warhead detonated, and his tracks clashed back into motion. He turned ponderously to the north once more, grinding out of the smoke and dust and the roaring brush fires his Enemy’s missiles had ignited in the valley’s sparse vegetation.

That bombardment had exhausted the Enemy’s ammunition, and with it his indirect fire capability. If it hadn’t, he would still be firing upon LNC. He wasn’t, which meant that if he meant to destroy LNC now, he must do so with direct fire… and come within reach of LNC’s Hellbore, as well.

My missile fire has failed to halt LNC. I am certain it has inflicted additional damage, but I doubt that it has crippled his Hellbore, and if his main battery remains operational, he retains the capability to destroy me just as he did HNR at Morville. He appears to have slowed still further, however, which may indicate my attack has further damaged his suspension.

I project his current speed of advance and heading on the maps from Main Memory. Given my speed advantage, I will overtake him within 2.03 hours, well short of his evident goal. I still do not know why he is so intent upon reaching the Avalon Mountains. Unlike Humans, Bolos require neither water nor food, and surely the rocky, barren, crevasse-riddled Badlands would provide LNC with better cover than the tree-grown mountains. I try once more to extrapolate his objective, to gain some insight into what now motivates him, and, once more, I fail.

But it does not matter. I will overtake him over seventy kilometers from the mountains, and when I do, one or both of us will die.

LNC ran the projections once more. It was difficult, for damaged core computer sections fluctuated, dropping in and out of his net. Yet even his crippled capabilities sufficed to confirm his fears; the Enemy would overtake him within little more than a hundred minutes, and desperation filled him. It was not an emotion earlier marks of Bolos had been equipped to feel-or, at least, to recognize when they did-but LNC had come to know it well. He’d felt it from the moment he realized his company couldn’t save Morville, that the Enemy would break through them and crush the Humans they fought to protect. But it was different now, darker and more bitter, stark with how close he’d come to reaching the mountains after all.
