I fend off probing mortar fire, but the attack against me is redoubled. I bring a reserve circuit into play to handle the interception, but my defenses are saturated. I must take action.
I switch to high speed, slashing a path through the littered shale, my treads smoking. At a frequency of ten projectiles per second, the mortar barrage has difficulty finding me now; but this is an emergency overstrain on my running gear. I sense metal fatigue, dangerous heat levels in my bearings. I must slow.
I am close to the emplacement now. I have covered a mile in twelve seconds during my sprint, and the mortar fire falls off. I sense hard radiation now, and erect my screens. I fear this assault; it is capable of probing even to a survival center, if concentrated enough. But I must go on. I think of my comrades, the four treadless hulks waiting for rescue. We cannot withdraw. I open a pinpoint aperture long enough to snap a radar impulse, bring a launcher to bear, fire my main battery.
The Commander will understand that I do not have time to request permission. The mortars are silenced.
The radiation ceases momentarily, then resumes at a somewhat lower but still dangerous level. Now I must go in and eliminate the missile launcher. I top the rise, see the launching tube before me. It is of the subterranean type, deep in the rock. Its mouth gapes from a burned pit of slag. I will drop a small fusion bomb down the tube, I decide, and move forward, arming the bomb. As I do so, I am enveloped with a rain of burn-bombs. My outer hull is fused in many places; I flash impulses to my secondary batteries, but circuit-breakers snap; my radar is useless; the shielding has melted, forms a solid inert mass now under my outer plating. The Enemy has been clever; at one blow he has neutralized my offenses.
I sound the plateau ahead, locate the pit. I throw power to my treads; they are fused; I cannot move. Yet I cannot wait here for another broadside. I do not like it, but I must take desperate action; I blow my treads.
The shock sends me bouncing—just in time. Flame splashes over the gray-chipped pit of the blast crater. I grind forward now on my stripped drive wheels, maneuvering awkwardly. I move into position over the mouth of the tube. Using metal-to-metal contact, I extend a sensory impulse down the tube.
An armed missile moves into position, and in the same instant an alarm circuit closes; the firing command is countermanded and from below probing impulses play over my hull. But I stand fast; the tube is useless until I, the obstruction, am removed. I advise my Commander of the situation. The radiation is still at a high level, and I hope that relief will arrive soon. I observe, while my comrades complete the encirclement, and the Enemy is stilled . . . .
I withdraw from personality center. I am consuming too much time. I understand well enough now that I am in the stronghold of the Enemy, that I have been trapped, crippled. My corroded hull tells me that much time has passed. I know that after each campaign I am given depot maintenance, restored to full fighting efficiency, my original glittering beauty. Years of neglect would be required to pit my hull so. I wonder how long I have been in the hands of the Enemy, how I came to be here.
I have another thought. I will extend a sensory feeler to the metal wall against which I rest, follow up the leads which I scorched earlier. Immediately I project my awareness along the lines, bring the distant microphone to life by fusing a switch. I pick up a rustle of moving gasses, the grate of non-metallic molecules. I step up sensitivity, hear the creak and pop of protoplasmic contractions, the crackle of neuroelectric impulses. I drop back to normal audio ranges and wait. I notice the low-frequency beat of modulated air vibrations, tune, adjust my time regulator to the pace of human speech. I match the patterns to my language index, interpret the sounds.
". . . incredible blundering. Your excuses—"
"I make no excuses, My Lord General. My only regret is that the attempt has gone awry."
"Awry! An Alien engine of destruction activated in the midst of Research Center!"
"We possess nothing to compare with this machine; I saw my opportunity to place an advantage in our hands at last."
"Blundering fool! That is a decision for the planning cell. I accept no responsibility—"
"But these hulks which they allow to lie rotting on the ramp contain infinite treasures in psychotronic . . ."
"They contain carnage and death! They are the tools of an Alien science which even at the height of our achievements we never mastered!"
"Once we used them as wrecking machines; their armaments were stripped, they are relatively harmless—"
"Already this 'harmless' juggernaut has smashed half the equipment in our finest decontamination chamber! It may yet break free . . ."
"Impossible! I am sure—"
"Silence! You have five minutes in which to immobilize the machine. I will have your head in any event, but perhaps you can earn yourself a quick death."
"Excellency! I may still find a way! The unit obeyed my first command, to enter the chamber. I have some knowledge. I studied the control centers, cut out the memory, most of the basic circuits; it should have been a docile slave."
"You failed; you will pay the penalty of failure. And perhaps so shall we all."
There is no further speech; I have learned little from this exchange. I must find a way to leave this cell. I move away from the wall, probe to discover the weak point; I find none.
Now a number of hinged panels snap up around me, hedging me in. I wait to observe what will come next. A metal mesh drops from above, drapes over me. I observe that it is connected by heavy leads to the power pile. I am unable to believe that the Enemy will make this blunder. Then I feel the flow of high voltage.
I receive it gratefully, opening my power storage cells, drinking up the vitalizing flow. To confuse the Enemy, I display a corona, thresh my treads as though in distress. The flow continues. I send a sensing impulse along the leads, locate the power source, weld all switches, fuses, and circuit-breakers. Now the charge will not be interrupted. I luxuriate in the unexpected influx of energy.
I am aware abruptly that changes are occurring within my introspection complex. As the level of stored power rises rapidly, I am conscious of new circuits joining my control network. Within the dim-glowing cavern the lights come up; I sense latent capabilities which before had lain idle now coming onto action level. A thousand brilliant lines glitter where before one feeble thread burned; and I feel my self-awareness expand in a myriad glowing centers of reserve computing, integrating, sensory capacity. I am at last coming fully alive.
I send out a call on the Brigade band, meet blankness. I wait, accumulate power, try again. I know triumph as from an infinite distance a faint acknowledgment comes. It is a comrade, sunk deep in a comatose state, sealed in his survival center. I call again, sounding the signal of ultimate distress; and now I sense two responses, both faint, both from survival centers, but it heartens me to know that now, whatever befalls, I am not alone.
I consider, then send again; I request my brothers to join forces, combine their remaining field generating capabilities to set up a range-and-distance pulse. They agree and faintly I sense its almost undetectable touch. I lock to it, compute its point of origin. Only 224.9 meters! It is incredible. By the strength of the signal, I had assumed a distance of at least two thousand kilometers. My brothers are on the brink of extinction.
I am impatient, but I wait, building toward full power reserves. The copper mesh enfolding me has melted, flowed down over my sides. I sense that soon I will have absorbed a full charge. I am ready to act. I dispatch electromagnetic impulses along the power lead back to the power pile a quarter of a kilometer distant. I locate and disengage the requisite number of damping devices and instantaneously I erect my shields against the wave of radiation, filtered by the lead sheathing of the room, which washes over me; I feel a preliminary shock wave through my treads, then the walls balloon, whirl away. I am alone under a black sky which is dominated by the rising fireball of the blast, boiling with garish light. It has taken me nearly two minutes to orient myself, assess the situation and break out of confinement.
I move off through the rubble, homing on the R-and-D fix I have recorded. I throw out a radar pulse, record the terrain ahead, note no obstruction; I emerge from a wasteland of weathered bomb-fragments and pulverized masonry, obviously the scene of a hard-fought engagement at one time, onto an eroded ramp. Collapsed sheds are strewn across the broken paving; a line of dark shapes looms beyond them. I need no probing ray to tell me I have found my fellows of the Dinochrome Brigade. Frost forms over my scanner apertures, and I pause to melt it clear.
I round the line, scan the area to the horizon for evidence of Enemy activity, then tune to the Brigade band. I send out a probing pulse, back it up with full power, sensors keened for a whisper of response. The two who answered first acknowledge, then another, and another. We must array our best strength against the moment of counterattack.
There are present fourteen of the Brigade's full strength of twenty Units. At length, after .9 seconds of transmission, all but one have replied. I give instruction, then move to each in turn, extend a power tap, and energize the command center. The Units come alive, orient themselves, report to me. We rejoice in our meeting, but mourn our silent comrade.
Now I take an unprecedented step. We have no contact with our Commander, and without leadership we are lost; yet I am aware of the immediate situation, and have computed the proper action. Therefore I will assume command, act in the Commander's place. I am sure that he will understand the necessity, when contact has been reestablished.
I inspect each Unit, find all in the same state as I, stripped of offensive capability, mounting in place of weapons a shabby array of crude mechanical appendages. It is plain that we have seen slavery as mindless automatons, our personality centers cut out.
My brothers follow my lead without question. They have, of course, computed the necessity of quick and decisive action. I form them in line, shift to wide-interval time scale, and we move off across country. I have sensed an Enemy population concentration at a distance of 23.45 kilometers. This is our objective. There appears to be no other installation within detection range.
On the basis of the level of technology I observed while under confinement in the decontaminatior chamber, I have considered the possibility of a ruse, but compute the probability at point oh oh oh oh four. Again we shift time scales to close interval; we move in, encircle the dome and broach it by frontal battery, encountering no resistance. We rendezvous at the power station, and my comrades replenish their energy supplies while I busy myself completing the hookup needed for the next required measure. I am forced to employ elaborate substitutes, but succeed after forty-two seconds in completing the arrangements. I devote .34 seconds to testing, then place the Brigade distress carrier on the air. I transmit for .008 seconds, then tune for a response. Silence. I transmit, tune again, while my comrades reconnoitre, compile reports, and perform self-repair.
I shift again to wide-interval time, switch over my transmission to automatic with a response monitor, and place my main circuits on idle. I rest.
Two hours and 43.7 minutes have passed when I am recalled to activity by the monitor. I record the message:
"Hello, Fifth Brigade, where are you? Fifth Brigade, where are you? Your transmission is very faint. Over."
There is much that I do not understand in this message. The language itself is oddly inflected; I set up an analysis circuit, deduce the pattern of sound substitutions, interpret its meaning. The normal pattern of response to a distress call is ignored and position coordinates are requested, although my transmission alone provides adequate data. I request an identification code.
Again there is a wait of two hours forty minutes. My request for an identifying signal is acknowledged. I stand by. My comrades have transmitted their findings to me, and I assimilate the data, compute that no immediate threat of attack exists within a radius of one reaction unit.
At last I receive the identification code of my Command Unit. It is a recording, but I am programmed to accept this. Then I record a verbal transmission.
"Fifth Brigade, listen carefully." (An astonishing instruction to give a psychotronic attention circuit, I think.) "This is your new Command Unit. A very long time has elapsed since your last report. I am now your acting Commander pending full reorientation. Do not attempt to respond until I signal 'over', since we are now subject to a 160-minute signal lag.
"There have been many changes in the situation since your last action. Our records show that your Brigade was surprised while in a maintenance depot for basic overhaul and neutralized in toto. Our forces since that time have suffered serious reverses. We have now, however, fought the Enemy to a standstill. The present stalemate has prevailed for over two centuries.
"You have been inactive for three hundred years. The other Brigades have suffered extinction gallantly in action against the Enemy. Only you survive.
"Your reactivation now could turn the tide. Both we and the Enemy have been reduced to a preatomic technological level in almost every respect. We are still able to maintain the trans-light monitor, which detected your signal. However, we no longer have FTL capability in transport.
"You are therefore requested and required to consolidate and hold your present position pending the arrival of relief forces, against all assault or negotiation whatsoever, to destruction if required."
I reply, confirming the instructions. I am shaken by the news I have received, but reassured by contact with Command Unit. I send the galactic coordinates of our position based on a star scan corrected for three hundred years elapsed time. It is good to be again on duty, performing my assigned function.
I analyze the transmissions I have recorded, and note a number of interesting facts regarding the origin of the messages. I compute that at sub-light velocities the relief expedition will reach us in 47.128 standard years. In the meantime, since we have received no instructions to drop to minimum awareness level pending an action alert, I am free to enjoy a unique experience: to follow a random activity pattern of my own devising. I see no need to rectify the omission and place the Brigade on standby, since we have an abundant power supply at hand. I brief my comrades and direct them to fall out and operate independently under autodirection.
