"It stands to reason," Shaaldaar said in his deliberate way. "We are all agreed that this is-or was-one of their important systems. So it must be linked to other Bug systems by various warp points. As soon as they became aware of our presence here, they must have summoned reinforcements from those systems by courier drone. The five standard days it took us to bring their mobile forces to bay and then fight the battle must have given those reinforcements time to arrive."

"Yes," Zhaarnak muttered. Prescott had no difficulty recognizing the emotions raging behind that alien face. It was a characteristic of Orions-and Zhaarnak, more than most-that a successful kill only whetted their appetite for more.

"They have no idea of our strength, or even of exactly where we are. We could go back into cloak, ambush them. . . ."

Zhaarnak let his voice trail off as he met Prescott's eyes. He could read his vilkshatha brother as readily as the human could read him.

"We must face facts," Prescott said into the silence. "We've taken losses ourselves-nine superdreadnoughts, seven battlecruisers, over seven hundred fighters. . . . And our stores of missiles of all kinds have been depleted. More importantly, the recon fighters' reports make it pretty clear that these Bugs are behaving normally. Whatever affected the Bugs in this system evidently doesn't have interstellar range. We had an opportunity, and we were justified in seizing it. But boldness is one thing, and recklessness is another."

Shaaldaar gave a smile that was as disconcertingly humanlike as everything else about his face.

"I believe it was your Human philosopher Clausewitz who observed that a plan which succeeds is bold and that one which fails is reckless."

Prescott smiled back at him.

"That's precisely the distinction. And to take on unshaken monitor battlegroups, even if we did manage to obtain tactical surprise, would be to risk a judgment of recklessness when history got around to considering us."

Zhaarnak's features reflected his inner conflict so well as to remind Prescott that the Orion face, like that of humans but unlike that of Terran cats, had evolved as an instrument of communication. Finally, his ears tilted forward and he gave the fluttering purr that was his race's sigh.

"You are correct. We have accomplished our objectives, and more. We will return to Zephrain in accordance with our original plan."

Sixth Fleet fell back toward the warp point, covered by its weary fighter pilots as the strikegroups fought a series of bickering actions at extreme range against the fresh Bug gunboats.

The last Enemy units were gone, escaped from this system that they had rendered uninhabitable.

The Fleet had failed to protect the Worlds Which Must Be Defended, or to arrive in time to prevent the destruction of the Fleet component which had been assigned originally to that task. The repercussions of the destruction of the Worlds Which Must Be Defended would have grave consequences for the war effort, and the loss of so many ships in such futile combat was . . . annoying.

Yet the affair hadn't been a total loss. The gunboats had been ordered to track the withdrawing Enemy starships to their warp point of exit, regardless of casualties-and they'd succeeded.

A handful of them had even survived long enough to report that warp point's location.

TFNS Dnepr transited before KONS Celmithyr'theaarnouw. So Raymond Prescott had a few moments to appreciate the sight of Zephrain A's yellow glow, and the distant orange spark of Zephrain B, before turning to his com screen and speaking formally.

"Fang Zhaarnak, I relieve you."

"I stand relieved, Fang Pressssscott."

The little ceremony had been agreed to in advance. Now they were back in the Zephrain system, which was part of the Terran Federation, duly ceded by the Khan, and where the massive Terran orbital fortresses made the TFN the predominant service in terms of both tonnage and personnel. So Prescott was now in command of Sixth Fleet, and they exchanged closed-lipped grins at the formality.

Those grins faded for a moment as they looked into one another's eyes and recalled those who would not be returning to Zephrain. The count was in now: 22,605 personnel of all races. There were also 5,017 wounded aboard the remaining ships.

But then the grins were back.

"Did your staff intelligence officer ever complete that estimate of the system's total population, Raaymmonnd?"

"Yes. Commander Chung did an extensive analysis of the sensor returns from Planets I and II. Based on the Bug population density the energy outputs imply, he estimates a total of-"

"-at least twenty billion Bugs!" Lieutenant Commander Togliatti looked around the ready room, where VF-94's surviving pilots sprawled, exhausted. "The spooks figure that there were eight to ten billion of them on the planet we waxed, and another twelve to fourteen billion on the other one."

They stared at him, punch-drunk. They'd gone sleepless for days, sustained by drugs, and completed their recovery aboard Wyvern just before warp transit. They no longer had any response in them.

But then Irma Sanchez gave him a look of disappointment.

"Twenty billion? Come on, Skipper! Is that all we killed?"

CHAPTER FOUR: "Surely that can't be right!"

Zephrain was a distant binary system. The orange K8v secondary component, with its small retinue of what were by courtesy referred to as planets, followed an orbit of over fifty percent eccentricity. Even at periastron, it barely swung within three light-hours of Component A. Currently, it was headed out to the Stygian regions where it spent most of its year and was barely visible from Xanadu, the second of that privileged coterie of inner planets that basked in Zephrain A's warm yellow G5v light. Gazing out the window of his office, Raymond Prescott could almost imagine himself on Old Terra.

Not quite, of course. It was always "not quite." The tree whose branches almost brushed against the window was a featherleaf, product of a well-developed local ecosystem which showed little sign of yielding to Terran imports. And practiced senses told him that the gravity was a shade on the low side-0.93 G, to be exact. Still, Zephrain A II was a singularly hospitable world for the humans who'd dubbed it Xanadu.

It was equally comfortable for Orions-and they had discovered it first. Reactionaries like Zhaarnak's father, and even relatively enlightened old-timers like Kthaara'zarthan, had never recovered from the Khan's precedent-shattering act of ceding the system to the Terran Federation.

The move had made sense, though. Indeed, it had become unavoidable the moment the teeming Bug system was found on the far side of one of Zephrain's four warp points. On the far side of another of those warp points lay Rehfrak, a sector capital of the Orions, with billions of the Khan's subjects, squarely in the path of any Bug counterattack an offensive might provoke. Only the Terran Federation, with its prodigious industrial capacity, could fortify Zephrain so heavily as to make any offensive use of the system thinkable.

A project on that scale had required a workforce of millions, and millions more to service the workforce. They'd come from every corner of the Federation. In the streets of Xanadu's instant prefab "cities" could be seen every variety of human being that Old Terra had spawned, and quite a few it hadn't. That was unusual in today's Federation. The Heart Worlds' once-polyglot populations had long since blended into "planetary ethnicities," while the young Fringe Worlds had been settled by people seeking to preserve various traditional ethnicities from disappearance by giving each its own planet.
