'I guess. So we can't touch them, and they know it.'
'Unless the lasers recover.' Didn't seem likely. 'We better get everybody under the dome. Us, too.'
He said a word whose vowel had changed over the centuries, but whose meaning was clear. 'No hurry. Let's see what they do.'
We waited for several hours. The temperature outside stabilized at 690 degrees – just under the melting point of zinc, I remembered to no purpose – and I tried the manual controls for the lasers, but they were still frozen.
'Here they come,' Charlie said. 'Eight again.'
I started for the display. 'Guess we'll–'
'Wait! They aren't drones.' The key identified all eight with the legend Troop Carrier.
'Guess they want to take the base,' he said. 'Intact.'
That, and maybe try out new weapons and techniques. 'It's not much of a risk for them. They can always retreat and drop a nova bomb in our laps.'
I called Brill and had her go get everybody who was in the stasis field, set them up with the remainder of her platoon as a defensive line circling around the northeast and northwest quadrants. I'd put the rest of the people in the other half-circle.
'I wonder,' Charlie said. 'Maybe we shouldn't put everyone topside at once. Until we know how many Taurans there are.'
That was a point. Keep a reserve, let the enemy under-estimate our strength. 'It's an idea… There might be just 64 of them in eight carriers.' Or 128 or 256. I wished our spy satellites had a finer sense of discrimination. But you can only cram so much into a machine the size of a grape.
I decided to let Brill's seventy people be our first line of defense and ordered them into a ring in the ditches we had made outside the base's perimeter. Everybody else would stay downstairs until needed.
If it turned out that the Taurans, either through numbers or new technology, could field an unstoppable force, I'd order everyone into the stasis field. There was a tunnel from the living quarters to the dome, so the people underground could go straight there in safety. The ones in the ditches would have to fall back under fire. If any of them were still alive when I gave the order.
I called in Hilleboe and had her and Charlie keep watch over the lasers. If they came unstuck, I'd call Brill and her people back. Turn on the automatic aiming system again, then sit back and watch the show. But even stuck, the lasers could be useful. Charlie marked the monitors to show where the rays would go; he and Hilleboe could fire them manually whenever something moved into a weapon's line-of-sight.
We had about twenty minutes. Brill was walking around the perimeter with her men and women, ordering them into the ditches a squad at a time, setting up overlapping fields of fire. I broke in and asked her to set up the heavy weapons so that they could be used to channel the enemy's advance into the path of the lasers.
There wasn't much else to do but wait. I asked Charlie to measure the enemy's progress and try to give us an accurate count-down, then sat at my desk and pulled out a pad, to diagram Brill's arrangement and see whether I could improve on it.
The cat jumped up on my lap, mewling piteously. He'd evidently been unable to tell one person from the other, suited up. But nobody else ever sat at this desk. I reached up to pet him and he jumped away.
The first line that I drew ripped through four sheets of paper. It had been some time since I'd done any delicate work in a suit. I remembered how in training, they'd made us practice controlling the strength-amplification circuits by passing eggs from person to person, messy business. I wondered if they still had eggs on Earth.
The diagram completed, I couldn't see any way to add to it. All those reams of theory crammed in my brain; there was plenty of tactical advice about envelopment and encirclement, but from the wrong point of view. If you were the one who was being encircled, you didn't have many options. Sit tight and fight. Respond quickly to enemy concentrations of force, but stay flexible so the enemy can't employ a diversionary force to divert strength from some predictable section of your perimeter. Make full use of air and space support, always good advice. Keep your head down and your chin up and pray for the cavalry. Hold your position and don't contemplate Dienbienphu, the Alamo, the Battle of Hastings.
'Eight more carriers out,' Charlie said. 'Five minutes. Until the first eight get here.'
So they were going to attack in two waves. At least two. What would I do, in the Tauran commander's position? That wasn't too far-fetched; the Taurans lacked imagination in tactics and tended to copy human patterns.
The first wave could be a throwaway, a kamikaze attack to soften us up and evaluate our defenses. Then the second would come in more methodically, and finish the job. Or vice versa: the first group would have twenty minutes to get entrenched; then the second could skip over their heads and hit us hard at one spot – breach the perimeter and over-run the base.
Or maybe they sent out two forces simply because two was a magic number. Or they could launch only eight troop carriers at a time (that would be bad, implying that the carriers were large; in different situations they had used carriers holding as few as 4 troops or as many as 128).
'Three minutes.' I stared at the cluster of monitors that showed various sectors of the mine field. If we were lucky, they'd land out there, out of caution. Or maybe pass over it low enough to detonate mines.
I was feeling vaguely guilty. I was safe in my hole, doodling, ready to start calling out orders. How did those seventy sacrificial lambs feel about their absentee commander?
Then I remembered how I had felt about Captain Stott that first mission, when he'd elected to stay safely in orbit while we fought on the ground. The rush of remembered hate was so strong I had to bite back nausea.
'Hilleboe, can you handle the lasers by yourself?'
'I don't see why not, sir.'
I tossed down the pen and stood up. 'Charlie, you take over the unit coordination; you can do it as well as I could. I'm going topside.'
'I wouldn't advise that, sir.'
'Hell no, William. Don't be an idiot.'
'I'm not taking orders, I'm giv–'
'You wouldn't last ten seconds up there,' Charlie said.
'I'll take the same chance as everybody else.'
'Don't you hear what I'm saying. They'll kill you!'
'The troops? Nonsense. I know they don't like me especially, but–'
'You haven't listened in on the squad frequencies?' No, they didn't speak my brand of English when they talked among themselves. 'They think you put them out on the line for punishment, for cowardice. After you'd told them anyone was free to go into the dome.'
'Didn't you, sir?' Hilleboe said.
'To punish them? No, of course not.' Not consciously. 'They were just up there when I needed… Hasn't Lieutenant Brill said anything to them?'
'Not that I've heard,' Charlie said. 'Maybe she's been too busy to tune in.
Or she agreed with them. 'I'd better get–'
'There!' Hilleboe shouted. The first empty ship was visible in one of the mine field monitors; the others appeared in the next second. They came in from random directions and weren't evenly distributed around the base. Five in the northeast quadrant and only one in the south-west. I relayed the information to Brill.
But we had predicted their logic pretty well; all of them were coming down in the ring of mines. One came close enough to one of the tachyon devices to set it off. The blast caught the rear end of the oddly streamlined craft, causing it to make a complete flip and crash nose-first. Side ports opened up and Taurans came crawling out. Twelve of them; probably four left inside. If all the others had sixteen as well, there were only slightly more of them than of us.
In the first wave.
The other seven had landed without incident, and yes; there were sixteen each. Brill shuffled a couple of squads to conform to the enemy's troop concentration, and she waited.
They moved fast across the mine field, striding in unison like bowlegged, top-heavy robots, not even breaking stride whe
n one of them was blown to bits by a mine, which happened eleven times.
When they came over the horizon, the reason for their apparently random distribution was obvious: they had analyzed beforehand which approaches would give them the most natural cover, from the rubble that the drones had kicked up. They would be able to get within a couple of kilometers of the base before we got any clear line-of-sight of them. And their suits had augmentation circuits similar to ours, so they could cover a kilometer in less than a minute.
Brill had her troops open fire immediately, probably more for morale than out of any hope of actually hitting the enemy. They probably were getting a few, though it was hard to tell. At least the tachyon rockets did an impressive job of turning boulders into gravel.
The Taurans returned fire with some weapon similar to the tachyon rocket, maybe exactly the same. They rarely found a mark, though; our people were at and below ground level, and if the rocket didn't hit something, it would keep going on forever, amen. They did score a hit on one of the gigawatt lasers, though, and the concussion that filtered down to us was strong enough to make me wish we had burrowed a little deeper than twenty meters.
The gigawatts weren't doing us any good. The Taurans must have figured out the lines of sight ahead of time, and gave them wide berth. That turned out to be fortunate, because it caused Charlie to let his attention wander from the laser monitors for a moment.
'What the hell?'
'What's that, Charlie?' I didn't take my eyes off the monitors. Waiting for something to happen.
'The ship, the cruiser – it's gone.' I looked at the holograph display. He was right; the only red lights were those that stood for the troop carriers.
'Where did it go?' I asked inanely.
'Let's play it back.' He programmed the display to go back a couple of minutes and cranked out the scale to where both planet and collapsar showed on the cube. The cruiser showed up, and with it, three green dots. Our 'coward,' attacking the cruiser with only two drones.
But he had a little help from the laws of physics.
Instead of going into collapsar insertion, he had skimmed around the collapsar field in a slingshot orbit. He had come out going nine-tenths of the speed of light; the drones were going .99 C, headed straight for the enemy cruiser. Our planet was about a thousand light seconds from the collapsar, so the Tauran ship had only ten seconds to detect and stop both drones. And at that speed, it didn't matter whether you'd been hit by a nova-bomb or a spitball.
The first drone disintegrated the cruiser, and the other one, .01 second behind, glided on down to impact on the planet. The fighter missed the planet by a couple of hundred kilometers and hurtled on into space, decelerating with the maximum twenty-five gees. He'd be back in a couple of months.
But the Taurans weren't going to wait. They were getting close enough to our lines for both sides to start using lasers, but they were also within easy grenade range. A good-size rock could shield them from laser fire, but the grenades and rockets were slaughtering them.
At first, Brill's troops had the overwhelming advantage; fighting from ditches, they could only be harmed by an occasional lucky shot or an extremely well-aimed grenade (which the Taurans threw by hand, with a range of several hundred meters). Brill had lost four, but it looked as if the Tauran force was down to less than half its original size.
Eventually, the landscape had been torn up enough so that the bulk of the Tauran force was able to fight from holes in the ground. The fighting slowed down to individual laser duels, punctuated occasionally by heavier weapons. But it wasn't smart to use up a tachyon rocket against a single Tauran, not with another force of unknown size only a few minutes away.
Something had been bothering me about that holographic replay. Now, with the battle's lull, I knew what it was.
When that second drone crashed at near-lightspeed, how much damage had it done to the planet? I stepped over to the computer and punched it up; found out how much energy had been released in the collision, and then compared it with geological information in the computer's memory.
Twenty times as much energy as the most powerful earthquake ever recorded. On a planet three-quarters the size of Earth.
On the general frequency: 'Everybody-topside! Right now!' I palmed the button that would cycle and open the airlock and tunnel that led from Administration to the surface.
'What the hell, Will–'
'Earthquake!' How long? 'Move!'
Hilleboe and Charlie were right behind me. The cat was sitting on my desk, licking himself unconcernedly. I had an irrational impulse to put him inside my suit, which was the way he'd been carried from the ship to the base, but knew he wouldn't tolerate more than a few minutes of it. Then I had the more reasonable impulse to simply vaporize him with my laser-finger, but by then the door was closed and we were swarming up the ladder. All the way up, and for some time afterward, I was haunted by the image of that helpless animal, trapped under tons of rubble, dying slowly as the air hissed away.
'Safer in the ditches?' Charlie said.
'I don't know,' I said. 'Never been in an earthquake.' Maybe the walls of the ditch would close up and crush us.
I was surprised at how dark it was on the surface. S Doradus had almost set; the monitors had compensated for the low light level.
An enemy laser raked across the clearing to our left, making a quick shower of sparks when it flicked by a gigawatt mounting. We hadn't been seen yet. We all decided yes, it would be safer in the ditches, and made it to the nearest one in three strides.
There were four men and women in the ditch, one of them badly wounded or dead. We scrambled down the ledge and I turned up my image amplifier to log two, to inspect our ditchmates. We were lucky; one was a grenadier and they also had a rocket launcher. I could just make out the names on their helmets. We were in Brill's ditch, but she hadn't noticed us yet. She was at the opposite end, cautiously peering over the edge, directing two squads in a flanking movement. When they were safely in position, she ducked back down. 'Is that you, Major?'
'That's right,' I said cautiously. I wondered whether any of the people in the ditch were among the ones after my scalp.
'What's this about an earthquake?'
She had been told about the cruiser being destroyed, but not about the other drone. I explained in as few words as possible.
'Nobody's come out of the airlock,' she said. 'Not yet. I guess they all went into the stasis field.'
'Yeah, they were just as close to one as the other.' Maybe some of them were still down below, hadn't taken my warning seriously. I chinned the general frequency to check, and then all hell broke loose.
The ground dropped away and then flexed back up; slammed us so hard that we were airborne, tumbling out of the ditch. We flew several meters, going high enough to see the pattern of bright orange and yellow ovals, the craters where nova bombs had been stopped. I landed on my feet but the ground was shifting and slithering so much that it was impossible to stay upright.
With a basso grinding I could feel through my suit, the cleared area above our base crumbled and fell in. Part of the stasis field's underside was exposed when the ground subsided; it settled to its new level with aloof grace.
Well, minus one cat. I hoped everybody else had time and sense enough to get under the dome.
A figure came staggering out of the ditch nearest to me and I realized with a start that it wasn't human. At that range, my laser burned a hole straight through his helmet; he took two steps and fell over backward. Another helmet peered over the edge of the ditch. I sheared the top of it off before he could raise his weapon.
I couldn't get my bearings. The only thing that hadn't changed was the stasis dome, and it looked the same from any angle. The gigawatt lasers were all buried, but one of them had switched on, a brilliant flickering searchlight that illuminated a swirling cloud of vaporized rock.
Obviously, though, I was in enemy territory. I started across the trembling ground toward the dome
.
I couldn't raise any platoon leaders. All of them but Brill were probably inside the dome. I did get Hilleboe and Charlie; told Hilleboe to go inside the dome and roust everybody out. If the next wave also had 128, we were going to need everybody.
The tremors died down and I found my way into a 'friendly' ditch – the cooks' ditch, in fact, since the only people there were Orban and Rudkoski.
'Looks like you'll have to start from scratch again, Private.'
'That's all right, sir. Liver needed a rest.'
I got a beep from Hilleboe and chinned her on. 'Sir … there were only ten people there. The rest didn't make it.'
'They stayed behind?' Seemed like they'd had plenty of time. 'I don't know, sir.'
'Never mind. Get me a count, how many people we have, all totalled.' I tried the platoon leaders' frequency again and it was still silent.
The three of us watched for enemy laser fire for a couple of minutes, but there was none. Probably waiting for reinforcements.
Hilleboe called back. 'I only get fifty-three, sir. Some may be unconscious.'
'All right. Have them sit tight until – ' Then the second wave showed up, the troop carriers roaring over the horizon with their jets pointed our way, decelerating. 'Get some rockets on those bastards!' Hilleboe yelled to everyone in particular. But nobody had managed to stay attached to a rocket launcher while he was being tossed around. No grenade launchers, either, and the range was too far for the hand lasers to do any damage.
These carriers were four or five times the size of the ones in the first wave. One of them grounded about a kilometer in front of us, barely stopping long enough to disgorge its troops. Of which there were over 50, probably 64 – times 8 made 512. No way we could hold them back.
'Everybody listen, this is Major Mandella.' I tried to keep my voice even and quiet. 'We're going to retreat back into the dome, quickly but in an orderly way. I know we're scattered all over hell. If you belong to the second or fourth platoon, stay put for a minute and give covering fire while the first and third platoons, and support, fall back.
'First and third and support, fall back to about half your present distance from the dome, then take cover and defend the second and fourth as they come back. They'll go to the edge of the dome and cover you while you come back the rest of the way.' I shouldn't have said 'retreat'; that word wasn't in the book. Retrograde action.
