The installation was partly protected from enemy fire by an efficient ablative layer that covered everything except the human operator. But then, they were dead-man switches. One man above guarding eighty inside. The army's good at that kind of arithmetic.

Once the bunker was finished, half of us stayed inside at all times feeling very much like targets taking turns operating the laser, while the other half went on maneuvers.

About four klicks from the base was a large 'lake' of frozen hydrogen; one of our most important maneuvers was to learn how to get around on the treacherous stuff.

It wasn't too difficult. You couldn't stand up on it, so you had to belly down and sled.

If you had somebody to push you from the edge, getting started was no problem. Otherwise, you had to scrabble with your hands and feet, pushing down as hard as was practical, until you started moving, in a series of little jumps. Once started, you'd keep going until you ran out of ice. You could steer a little bit by digging in, hand and foot, on the appropriate side, but you couldn't slow to a stop that way. So it was a good idea not to go too fast and wind up positioned in such a way that your helmet didn't absorb the shock of stopping.

We went through all the things we'd done on the Miami side: weapons practice, demolition, attack patterns. We also launched drones at irregular intervals, toward the bunker. Thus, ten or fifteen times a day, the operators got to demonstrate their skill in letting go of the handles as soon as the proximity light went on.

I had four hours of that, like everybody else. I was nervous until the first 'attack,' when I saw how little there was to it. The light went on, I let go, the gun aimed, and when the drone peeped over the horizon zzt! Nice touch of color, the molten metal spraying through space. Otherwise not too exciting.

So none of us were worried about the upcoming 'graduation exercise,' thinking it would be just more of the same.

Miami Base attacked on the thirteenth day with two simultaneous missiles streaking over opposite sides of the horizon at some forty kilometers per second. The laser vaporized the first one with no trouble, but the second got within eight klicks of the bunker before it was hit.

We were coming back from maneuvers, about a klick away from the bunker. I wouldn't have seen it happen if I hadn't been looking directly at the bunker the moment of the attack.

The second missile sent a shower of molten debris straight toward the bunker. Eleven pieces hit, and, as we later reconstructed it, this is what happened: The first casualty was Maejima, so well-loved Maejima, inside the bunker, who was hit in the back and the head and died instantly. With the drop in pressure, the LSU went into high gear. Friedman was standing in front of the main airco outlet and was blown into the opposite wall hard enough to knock him unconscious; he died of decompression before the others could get him to his suit.

Everybody else managed to stagger through the gale and get into their suits, but Garcia's suit had been holed and didn't do him any good.

By the time we got there, they had turned off the LSU and were welding up the holes in the wall. One man was trying to scrape up the unrecognizable mess that had been Maejima. I could hear him sobbing and retching. They had already taken Garcia and Friedman outside for burial. The captain took over the repair detail from Potter. Sergeant Cortez led the sobbing man over to a corner and came back to work on cleaning up Maejima's remains, alone. He didn't order anybody to help and nobody volunteered.

10.

As a graduation exercise, we were unceremoniously stuffed into a ship Earth's Hope, the same one we rode to Charon and bundled off to Stargate at a little more than one gee.

The trip seemed endless, about six months subjective time, and boring, but not as hard on the carcass as going to Charon had been. Captain Stott made us review our training orally, day by day, and we did exercises every day until we were worn to a collective frazzle.

Stargate 1 was like Charon's darkside, only more so. The base on Stargate 1 was smaller than Miami Base only a little bigger than the one we constructed on darkside and we were due to lay over a week to help expand the facilities. The crew there was very glad to see us, especially the two females, who looked a little worn around the edges.

We all crowded into the small dining hall, where Sub-major Williamson, the man in charge of Stargate 1, gave us some disconcerting news: 'Everybody get comfortable. Get off the tables, though, there's plenty of floor.

'I have some idea of what you just went through, training on Charon. I won't say it's all been wasted. But where you're headed, things will be quite different. Warmer.'

He paused to let that soak in.

'Aleph Aurigae, the first collapsar ever detected, revolves around the normal star Epsilon Aurigae in a twenty-seven year orbit. The enemy has a base of operations, not on a regular portal planet of Aleph, but on a planet in orbit around Epsilon. We don't know much about the - planet, just that it goes around Epsilon once every 745 days, is about three-fourths the size of Earth, and has an albedo of 0.8, meaning it's probably covered with clouds. We can't say precisely how hot it will be, but judging from its distance from Epsilon, it's probably rather hotter than Earth. Of course, we don't know whether you'll be working ... fighting on lightside or darkside, equator or poles. It's highly unlikely that the atmosphere will be breathable at any rate, you'll stay inside your suits.

Now you know exactly as much about where you're going as I do. Questions?'

'Sir,' Stein drawled, 'now we know where we're goin' ... anybody know what we're goin' to do when we get there?'

Williamson shrugged. 'That's up to your captain and your sergeant, and the captain of Earth's Hope, and Hope's logistic computer. We just don't have enough data yet to project a course of action for you. It may be a long and bloody battle; it may be just a case of walking in to pick up the pieces. Conceivably, the Taurans might want to make a peace offer,' Cortez snorted 'in which case you would simply be part of our muscle, our bargaining power.' He looked at Cortez mildly. 'No one can say for sure.'

The orgy that night was amusing, but it was like trying to sleep in the middle of a raucous beach party. The only area big enough to sleep all of us was the dining hall; they draped a few bedsheets here and there for privacy, then unleashed Stargate's eighteen sex-starved men on our women, compliant and promiscuous by military custom (and law), but desiring nothing so much as sleep on solid ground.

The eighteen men acted as if they were compelled to try as many permutations as possible, and their performance was impressive (in a strictly quantitative sense, that is). Those of us who were keeping count led a cheering section for some of the more gifted members. I think that's the right word.

The next morning and every other morning we were on Stargate 1 we staggered out of bed and into our suits, to go outside and work on the 'new wing.' Eventually, Stargate would be tactical and logistic headquarters for the war, with thousands of permanent personnel, guarded by half-a-dozen heavy cruisers in Hope's class. When we started, it was two shacks and twenty people; when we left, it was four shacks and twenty people. The work was hardly work at all, compared to darkside, since we had plenty of light and got sixteen hours inside for every eight hours' work. And no drone attack for a final exam.

When we shuttled back up to the Hope, nobody was too happy about leaving (though some of the more popular females declared it'd be good to get some rest). Stargate was the last easy, safe assignment we'd have before taking up arms against the Taurans. And as Williamson had pointed out the first day, there was no way of predicting what that would be like.

Most of us didn't feel too enthusiastic about making a collapsar jump, either. We'd been assured that we wouldn't even feel it happen, just free fall all the way.

I wasn't convinced. As a physics student, I'd had the usual courses in general relativity and theories of gravitation. We only had a little direct data at that time Stargate was discovered when I was in grade school but the mathematical model seemed clear enough.

The collapsar Stargate was a perfect sphere about three kilometers in radius. It was suspended forever in a state of gravitational collapse that should have meant its surface was dropping toward its center at nearly the speed of light. Relativity propped it up, at least gave it the illusion of being there ... the way all reality becomes illusory and observer-oriented when you study general relativity. Or Buddhism. Or get drafted.

At any rate, there would be a theoretical point in space-time when one end of our ship was just above the surface of the collapsar, and the other end was a kilometer away (in our frame of reference). In any sane universe, this would set up tidal stresses and tear the ship apart, and we would be just another million kilograms of degenerate matter on the theoretical surface, rushing headlong to nowhere for the rest of eternity or dropping to the center in the next trillionth of a second. You pays your money and you takes your frame of reference.

But they were right. We blasted away from Stargate 1, made a few course corrections and then just dropped, for about an hour.

Then a bell rang and we sank into our cushions under a steady two gravities of deceleration. We were in enemy territory.

11.

We'd been decelerating at two gravities for almost nine days when the battle began. Lying on our couches being miserable, all we felt were two soft bumps, missiles being released. Some eight hours later, the squawk-box crackled: 'Attention, all crew. This is the captain.' Quinsana, the pilot, was only a lieutenant, but was allowed to call himself captain aboard the vessel, where he outranked all of us, even Captain Stott. 'You grunts in the cargo hold can listen, too.

'We just engaged the enemy with two fifty-gigaton tachyon missiles and have destroyed both the enemy vessel and another object which it had launched approximately three microseconds before.

'The enemy has been trying to overtake us for the past 179 hours, ship time. At the time of the engagement, the enemy was moving at a little over half the speed of light, relative to Aleph, and was only about thirty AUs from Earth's Hope. It was moving at .47c relative to us, and thus we would have been coincident in space-time' rammed! 'in a little more than nine hours. The missiles were launched at 0719 ship's time, and destroyed the enemy at 1540, both tachyon bombs detonating within a thousand klicks of the enemy objects.'

The two missiles were a type whose propulsion system was itself only a barely-controlled tachyon bomb. They accelerated at a constant rate of 100 gees, and were traveling at a relativistic speed by the time the nearby mass of the enemy ship detonated them.

'We expect no further interference from enemy vessels. Our velocity with respect to Aleph will be zero in another five hours; we will then begin the journey back. The return will take twenty-seven days.' General moans and dejected cussing. Everybody knew all that already, of course; but we didn't care to be reminded of it.

So after another month of logy calisthenics and drill, at a constant two gravities, we got our first look at the planet we were going to attack. Invaders from outer space, yes sir.

It was a blinding white crescent waiting for us two AUs out from Epsilon. The captain had pinned down the location of the enemy base from fifty AUs out, and we had jockeyed in on a wide arc, keeping the bulk of the planet between them and us. That didn't mean we were sneaking up on them quite the contrary; they launched three abortive attacks but it put us in a stronger defensive position. Until we had to go to the surface, that is. Then only the ship and its Star Fleet crew would be reasonably safe.

Since the planet rotated rather slowly once every ten and one-half days a 'stationary' orbit for the ship had to be 150,000 klicks out. This made the people in the ship feel quite secure, with 6,000 miles of rock and 90,000 miles of space between them and the enemy. But it meant a whole second's time lag in communication between us on the ground and the ship's battle computer. A person could get awful dead while that neutrino pulse crawled up and back.

Our vague orders were to attack the base and gain control, while damaging a minimum of enemy equipment. We were to take at least one enemy alive. We were under no circumstances to allow ourselves to be taken alive, however. And the decision wasn't up to us; one special pulse from the battle computer, and that speck of plutonium in your power plant would fiss with all of .01% efficiency, and you'd be nothing but a rapidly expanding, very hot plasma.

They strapped us into six scoutships one platoon of twelve people in each and we blasted away from Earth's Hope at eight gees. Each scoutship was supposed to follow its own carefully random path to our rendezvous point, 108 klicks from the base. Fourteen drone ships were launched at the same time, to confound the enemy's anti-spacecraft system.

The landing went off almost perfectly. One ship suffered minor damage, a near miss,boiling away some of the ablative material on one side of the hull, but it'd still be able to make it and return, keeping its speed down while in the atmosphere.

We zigged and zagged and wound up first ship at the rendezvous point. There was only one trouble. It was under four kilometers of water.

I could almost hear that machine, 90,000 miles away, grinding its mental gears, adding this new bit of data. We proceeded just as if we were landing on solid ground: braking rockets, falling, skids out, hit the water, skip, hit the water, skip, hit the water, sink.

It would have made sense to go ahead and land on the bottom we were streamlined, after all, and water just another fluid but the hull wasn't strong enough to hold up a four kilometer column of water. Sergeant Cortez was in the scoutship with us.

'Sarge, tell that computer to do something! We're gonna get'

'Oh, shut up, Mandella. Trust in th' lord.' 'Lord' was definitely lower-case when Cortez said it.

There was a loud bubbly sigh, then another, and a slight increase in pressure on my back that meant the ship was rising. 'Flotation bags?' Cortez didn't deign to answer, or didn't know.

That was it. We rose to within ten or fifteen meters of the surface and stopped, suspended there. Through the port I could see the surface above, shimmering like a mirror of hammered silver. I wondered what it would be like to be a fish.and have a definite roof over your world.

I watched another ship splash in. It made a great cloud of bubbles and turbulence, then fell slightly tail-first for a short distance before large bags popped out under each delta wing. Then it bobbed up to about our level and stayed.

'This is Captain Stott. Now listen carefully. There is a beach some twenty-eight klicks from your present position, in the direction of the enemy. You will be proceeding to this beach by scoutship and from there will mount your assault on the Tauran position.' That was some improvement; we'd only have to walk eighty klicks.

We deflated the bags, blasted to the surface and flew in a slow, spread-out formation to the beach. It took several minutes. As the ship scraped to a halt, I could hear pumps humming, making the cabin pressure equal to the air pressure outside. Before it had quite stopped moving, the escape slot beside my couch slid open. I rolled out onto the wing of the craft and jumped to the ground. Ten seconds to find cover I sprinted across loose gravel to the 'treeline,' a twisty bramble of tall sparse bluish-green shrubs. I dove into the briar patch and turned to watch the ships leave. The drones that were left rose slowly to about a hundred meters, then took off in all directions with a bone-jarring roar. The real scoutships slid slowly back into the water. Maybe that was a good idea.

It wasn't a terribly attractive world but certainly would be easier to get around in than the cryogenic nightmare we were trained for. The sky was a uniform dull silver brightness that merged with the mist over the ocean so completely it was impossible to tell where water ended and air began. Small wavelets licked at the black gravel shore, much too slow and graceful in the three-quarters Earth-normal gravity. Even from fifty meters away, the rattle of billions of pebbles rolling with the tide was loud in my ears.

The air temperature was 79 degrees Centigrade, not quite hot enough for the sea to boil, even though the air pressure was low compared to Earth's. Wisps of steam drifted quickly upward from the line where water met land. I wondered how a lone man would survive exposed here without a suit. Would the heat or the low oxygen (partial pressure one-eighth Earth normal) kill him first? Or was there some deadly microorganism that would beat them both...?

'This is Cortez. Everybody come over and assemble on me.' He was standing on the beach a little to the left of me, waving his hand in a circle over his head. I walked toward him through the shrubs. They were brittle, unsubstantial, seemed paradoxically dried-out in the steamy air. They wouldn't offer much in the way of cover.

'We'll be advancing on a heading .05 radians east of north. I want Platoon One to take point. Two and Three follow about twenty meters behind, to the left and right. Seven, command platoon, is in the middle, twenty meters behind Two and Three. Five and Six, bring up the rear, in a semicircular closed flank. Everybody straight?' Sure, we could do that 'arrowhead' maneuver in our sleep. 'OK, let's move out.'

I was in Platoon Seven, the 'command group.' Captain Stott put me there not because I was expected to give any commands, but because of my training in physics.

The command group was supposedly the safest place, buffered by six platoons: people were assigned to it because there was some tactical reason for them to survive at least a little longer than the rest. Cortez was there to give orders. Chavez was there to correct suit malfunctions. The senior medic, Doc Wilson (the only medic who actually had an M.D.), was there, and so was Theodopolis, the radio engineer, our link with the captain, who had elected to stay in orbit.

The rest of us were assigned to the command group by dint of special training or aptitude that wouldn't' normally be considered of a 'tactical' nature. Facing a totally unknown enemy, there was no way of telling what might prove important. Thus I was there because I was the closest the company had to a physicist. Rogers was biology. Tate was chemistry. Ho could crank out a perfect score on the Rhine extrasensory perception test, every time. Bohrs was a polyglot, able to speak twenty-one languages fluently, idiomatically. Petrov's talent was that he had tested out to have not one molecule of xenophobia in his psyche. Keating was a skilled acrobat. Debby Hollister 'Lucky' Hollister showed a remarkable aptitude for making money, and also had a consistently high Rhine potential.

12.

When we first set out, we were using the 'jungle' camouflage combination on our suits. But what passed for jungle in these anemic tropics was too sparse; we looked like a band of conspicuous harlequins trooping through the woods. Cortez had us switch to black, but that was just as bad, as the light of Epsilon came evenly from all parts of the sky, and there were no shadows except ours. We finally settled on the dun-colored desert camouflage.

The nature of the countryside changed slowly as we walked north, away from the sea. The thorned stalks I guess you could call them trees came in fewer numbers but were bigger around and less brittle; at the base of each was a tangled mass of vine with the same bluegreen color, which spread out in a flattened cone some ten meters in diameter. There was a delicate green flower the size of a man's head near the top of each tree.

Grass began to grow some five klicks from the sea. It seemed to respect the trees' 'property rights,' leaving a strip of bare earth around each cone of vine. At the edge of such a clearing, it would grow as timid bluegreen stubble, then, moving away from the tree, would get thicker and taller until it reached shoulderhigh in some places, where the separation between two trees was unusually large. The grass was a lighter, greener shade than the trees and vines. We changed the color of our suits to the bright green we had used for maximum visibility on Charon. Keeping to the thickest part of the grass, we were fairly inconspicuous.

We covered over twenty klicks each day, buoyant after months under two gees. Until the second day, the only form of animal life we saw was a kind of black worm, finger-sized, with hundreds of cilium legs like the bristles of a brush. Rogers said that there obviously had to be some larger creature around, or there would be no reason for the trees to have thorns. So we were doubly on guard, expecting trouble both from the Taurans and the unidentified 'large creature.'

Potter's second platoon was on point; the general freak was reserved for her, since her platoon would likely be the first to spot any trouble. 'Sarge, this is Potter,' we all heard. 'Movement ahead.'

'Get down, then!'

'We are. Don't think they see us.'

'First platoon, go up to the right of point. Keep down. Fourth, get up to the left. Tell me when you get in position. Sixth platoon, stay back and guard the rear. Fifth and third, close with the command group.'

Two dozen people whispered out of the grass to join us. Cortez must have heard from the fourth platoon.

'Good. How about you, first?... OK, fine. How many are there?'

'Eight we can see.' Potter's voice.

'Good. When I give the word, open fire. Shoot to kill.'

'Sarge... they're just animals.'

'Potter if you've known all this time what a Tauran looks like,- you should've told us. Shoot to kill.'

'But we need...'

'We need a prisoner, but we don't need to escort him forty klicks to his home base and keep an eye on him while we fight. Clear?'

'Yes. Sergeant.'

'OK. Seventh, all you brains and weirds, we're going up and watch. Fifth and third, come along to guard.'

We crawled through the meter-high grass to where the second platoon had stretched out in a firing line.

'I don't see anything,' Cortez said.

'Ahead and just to the left. Dark green.'

They were only a shade darker than the grass. But after you saw the first one, you could see them all, moving slowly around some thirty meters ahead.

'Fire!' Cortez fired first; then twelve streaks of crimson leaped out and the grass wilted black, disappeared, and the creatures convulsed and died trying to scatter.

'Hold fire, hold it!' Cortez stood up. 'We want to have something left second platoon, follow me.' He strode out toward the smoldering corpses, laser-finger pointed out front, obscene divining rod pulling him toward the carnage... I felt my gorge rising and knew that all the lurid training tapes, all the horrible deaths in training accidents, hadn't prepared me for this sudden reality ... that I had a magic wand that I could point at a life and make it a smoking piece of half-raw meat; I wasn't a soldier nor ever wanted to be one nor ever would want 'OK, seventh, come on up.' While we were walking toward them, one of the creatures moved, a tiny shudder, and Cortez flicked the beam of his laser over it with an almost negligent gesture. It made a hand-deep gash across the creature's middle. It died, like the others, without emitting a sound.
