Earth had learned enough in the last few months to know her technology was better, but it was beginning to appear her advantage might not be great enough, for the Achuultani had surprises of their own.

Like those damned hyper drives. Achuultani ships were slow even in hyper, but their hyper drives did things Horus had always thought were impossible. They could operate twice as deep into a stellar gravity well as an Imperial hypership, and their missile launchers were incredible. Achuultani sublight missiles, though fast, weren’t too dangerous—Earth’s defenders had better computers, better counter-missiles, and more efficient shield generators—but their hyper missiles were another story. Somehow, and Horus would have given an arm to know how, the Achuultani generated external hyper fields around their missiles, without the massive on-board hyper drives human missiles required.

Their launchers’ rate of fire was lower, but they were small enough the Achuultani could pack them in in unbelievable numbers, and they tended to fire their salvos in shoals, scattered over the hyper bands. A shield could cover only so many bands at once, and with luck, they could pop a missile through one the shield wasn’t guarding—a trick which had cost Earth’s warships dearly.

Their energy weapons, on the other hand, relied upon quaint, short-ranged developments of laser technology, which left a gap in their defenses. It wasn’t very wide, but if Earth’s defenders could get into it, they were too close for really accurate Achuultani hyper missile-fire and beyond their effective energy weapon range. The trick was surviving to get there.

And they really did like kinetic weapons. So far, they’d managed to hit the planetary shield with scores of projectiles, the largest something over a billion tons, and virtually wiped out Earth’s orbital industry. They’d nailed two ODCs, as well, picking them off with missiles when the main shield was slammed back into atmosphere behind them by kinetic assault.

To date, Vassily had managed to hold that shield against everything they threw at him, but the big, blond Russian was growing increasingly grim-faced. The PDC shield generators had been designed to provide a fifty percent reserve—but that was before they knew about Achuultani hyper missiles. Covering the wide-band attacks coming at him took every generator he had, and at ruinous overload. Without the core tap, not even the PDCs could have held them.

Which was largely what this conference was about.

“I don’t see an option, Horus,” Hatcher said finally. “We’ve got to have that tap. If we shut down and they hit us before we power back up—”

“Gerald,” Chernikov said, “we never meant this tap to carry such loads so long. The control systems are collapsing. I am into the secondary governor ring in places; if it goes, there are only the tertiaries to hold it.”

“But even if we shut down, will it be any safer to power back up?”

“No,” Chernikov conceded unhappily. “Not without repairs.”

“Then, Vassily, it is a choice between a possibility of losing control and the probability of losing the planet,” Tsien said quietly.

“I know that. But it will do us no good to blow up Antarctica and lose the tap—permanently—into the bargain.”

“Agreed.” Horus’s quiet voice snapped all eyes back to him. “Are your replacement components ready for installation, Vassily?”

“They are. We will require two-point-six hours to change over, but I must shut down to do it.”

“Very well.” Horus felt responsibility crushing down upon him. “When the first secondary system goes down, we’ll shut down long enough for complete control replacement.”

Tsien and Hatcher looked as if they wanted to argue, but they were soldiers. They recognized an order when they heard it.

“Now.” Horus turned his attention to Admiral Hawter. “What can you tell us about your own situation, Isaiah?”

“It’s not good,” Hawter said heavily. “The biggest problem is the difference in our shield technologies. We generate a single bubble around a unit; they generate a series of plate-like shields, each covering one aspect of the target, with about a twenty percent overlap at the edges. They pay for it with a much less efficient power ratio, but it gives them redundancy we don’t have and lets them bring them in closer to the hull. That’s our problem.”

Heads nodded. Hyper missiles weren’t seeking weapons; they went straight to their pre-programmed coordinates, and the distance between shield and hull effectively made Earth’s ships bigger targets. All too often, a hyper missile close enough to penetrate a human warship’s shield detonated outside an Achuultani ship’s shields—which, coupled with the Achuultani’s greater ability to saturate the hyper bands, left Hawter’s ships at a grievous disadvantage.

“Our missiles out-range theirs, and we’ve refined our targeting systems to beat their jammers—which, by the way, are still losing ground to our own—but if we stay beyond their range, we can’t get our warheads in close enough, either. Not without bigger salvos than most of our ships can throw. As long as they stay far enough out to use their micro-jump advantage, as well, we can only fight them on their terms, and that’s bad business.”

“How bad?” General Ki asked.

“Bad. We started out with a hundred and twenty battleships, twice that many cruisers, and about four hundred destroyers. We’re down to thirty-one battleships, ninety-six cruisers, and one hundred and seven destroyers—that’s a loss of five hundred and thirty-six out of an initial strength of seven hundred and seventy. In return, we’ve knocked out about nine hundred of their ships. I’ve got confirmed kills on seven hundred eighty-two and probables on another hundred fifty or so. That’s one hell of a lot more tonnage than we’ve lost, and, by our original estimates, that should have been all of them; as it is, it looks like a bit less than fifty percent.

“What it boils down to is that they’ve ground us away. If they move against us in force, we no longer have the mobile units to meet them in deep space.”

“In short,” Horus interjected softly, “they’ve won control of the Solar System beyond the reach of Earth’s own weapons.”

“Exactly, Governor,” Hawter said grimly. “We’re holding so far, but by the skin of our teeth. And this is only the scouting force.”

They were still staring at one another in glum silence when the alarms shrieked.

Both of Brashieel’s stomachs tightened as Vindicator moved in-system. The Demon Sector was living up to its name, Tarhish take it! Almost half the scouts had died striving against this single wretched planet, and if the scouts were but a few pebbles in the avalanche of Great Lord Tharno’s fleet, there were many suns in this sector—including the ones which must have built those scanner arrays. It could not have been these nest-killers, for none of their ships were even hyper-capable. But if these nest-killers had such weapons, who knew what else awaited the Protectors?

Yet they were pushing the nest-killers back. Lord of Thought Mosharg had counted the nest-killers they had sent to Tarhish carefully, and few of their foes’ impossibly powerful warships could remain.

Still, it seemed rash to press an attack so deep into the inner system. The nest-killers were twice as fast as Vindicator when he could not flee into hyper. If this was an ambush, the Great Visit’s scouts could lose heavily.

But Brashieel was no lord. Perhaps the purpose was to evaluate the nest-killers’ close defenses before the Hoof of Tarhish was released upon them? That made sense, even to an assistant servant like him, especially in light of their orders to attack the sunward pole of the planet. Yet to risk a half-twelve of twelves of scouts in this fashion took courage. Which might be why Lords Chirdan and Mosharg were lords and Brashieel was an assistant servant.
