Shiva Option s-3

  And that was what made it so frustrating, for the heavy Fleet units that should have defended this system were gone-called away to intercept this very Enemy force on its way home!

  Naturally, courier drones had gone out as soon as the System Which Must Be Defended had come under attack, summoning those heavy units to return. But now, quite clearly, there would be nothing here to defend by the time they could return.

  So new courier drones must be sent out, to meet the returning units at some point along the warp chain and order them to return post-haste to where they had originally been sent. There, they could at least still cut off this Enemy force as it retired.

  It was still difficult to do things rapidly-the aftereffects of the deaths of the first and third planets lingered stubbornly. But it must be done. Otherwise, those units might miss the Enemy both here and at the system where the survey flotilla had been ambushed.

  That would be . . . intensely frustrating.

  Irma Sanchez activated her F-4's internal hetlasers. Her eyesight was saved by the fighter's computer, which automatically dimmed her visual display as the Bug shuttle vanished with the unique violence of matter/antimatter annihilation.

  As she pulled away, she allowed herself to feel a sense of satisfaction.

  This had been, she had reason to believe, the last of the kamikaze shuttles. Not one of them had reached TF 71's capital ships. And the orbital fortresses that had sent them out on their forlorn-hope mission were no more, buried under an avalanche of long-range bombardment.

  Shortly, the Gorm gunboats would be launched. They would spearhead the destruction of the now-naked planet that showed as a pale-blue disc up ahead. But the Terran and Ophiuchi and Orion fighters would also play a part.

  She'd never really caught up on her sleep after the desperate fight with the gunboats. But the thought of what was to come filled her with an exhilaration that banished exhaustion.

  The task force was headed outward towards the warp point, with the three now-lifeless planets receding astern, when Raymond Prescott's staff met once again in Riva y Silva's flag briefing room. This time, Shaaldaar, Kolchak, Raathaarn, and Cole were in attendance via com screens, and Prescott wasted no time in coming to the point.

  "I realize that some of you are surprised that I've ordered an immediate departure, without pausing to finish off the warp point defenses."

  They were all taken back by the bluntness-the more so because what he'd said was absolutely true. Long-range sensor probes had confirmed SF 62's conclusions concerning the Bug forces defending each of Home Hive One's five open warp points: thirty-five orbital fortresses of monitor-like size, plus forty-two of the purpose-built warp point defense heavy cruisers. The Bugs had sensibly declined to send those cruisers in-system to the aid of the habitable planets. Nowadays, nothing lighter than a battlecruiser had any business in a fleet engagement-and especially not when it was as slow as they were. Still, that was a lot of tonnage . . . and a lot of Bugs. . . .

  Prescott smiled into their unspoken curiosity.

  "Rest assured that I would have preferred to make a clean sweep. Nevertheless, we've achieved our primary objective by sterilizing the inhabited planets, and there are sound reasons not to linger here.

  "First of all, we must assume that the Bugs sent out courier drones as soon as they became aware of our presence. We have no way of knowing how long their reinforcements are going to take to get here, but when they do . . . Well, we've taken significant losses, especially among our fighters."

  Prescott turned to Landrum as though inviting confirmation.

  "That's true, Sir," the farshathkhanaak acknowledged. "We started with almost two thousand fighters. We're down to eight hundred and forty-eight."

  "And our depletable munitions are getting lower than I'd like to see, Sir," Commander Sandra Ruiz, the logistics officer, piped up. "In particular, our SBMHAWKs are down to three hundred and twenty Mark Threes and only forty Mark Fours. Granted, we still have three hundred and sixty SRHAWKs of all marks, and nine hundred and fifty-six RD2s that we can deploy. But-"

  "I'm aware of the problem, Commander." Prescott ran his eyes around the table, and also across the row of com screens. "Given what Commodore Landrum and Commander Ruiz have just said, it should be clear why I have no desire to face fresh Bug forces in this system, here at the end of a long warp chain which, for all we know, may already have been cut behind us."

  They were all silent, although Prescott's last seven words weren't really a shock. Intellectually, they all knew the danger. But Prescott decided it ought to be put into words, and he knew just the man for the job.

  He turned to Mukerji-there'd been no way to avoid inviting him, after all, so he might as well make himself useful.

  "Admiral Mukerji, you have a comment or questions?"

  "Ah . . . I assume, Admiral, that you're referring to the closed warp point in AP-5."

  "Of course. As it happens, I have reason to believe that Bug forces have in fact been dispatched there. Furthermore, I have a pretty fair idea of those forces' strength."

  That got everyone's attention, especially Amos Chung's. Despite the gravity of the situation, Prescott was actually tempted to smile as every eye stared at him with emotions which varied from simple surprise to the sort of wariness only to be expected from someone who'd suddenly found himself trapped in a small room with a lunatic. He suppressed the temptation, however, and proceeded to outline the conclusions he'd reached shortly after entering Home Hive One. When he was done, they sat open-mouthed.

  Mukerji surprised him by being the first to find his voice.

  "Admiral, this warp chain you're postulating, running from one of Home Hive One's warp points back to AP-5 parallel to the Prescott Chain . . . You realize, of course, that it's sheer speculation."

  "True, in the sense that I have no direct evidence of its existence. But the theory accounts for the absence of the system's heavy mobile units-accounts for it too well for coincidence. For now, I see no reason to stop using it as a working assumption, at any rate."

  Prescott waited for Mukerji to say something about the possible political consequences if the assumption was mistaken. But the latter had learned better. Without letting the pause stretch too far, Prescott resumed.

  "So, as you can all see, we can't afford to waste any of our remaining combat strength against warp point fortresses that no longer have anything to guard. Not when we'll need everything we have left to fight our way through that force, if it's in AP-5 when we get there. But there's also another aspect to consider."

  "Sir?" Mandagalla inquired, and Prescott leaned forward and let his smile grow predatory.

  "Remember what I said earlier about the courier drones that must have gone out from the system when our attack commenced. Well, if I'm right about where those mobile forces went, maybe one of those drones went to AP-5 to recall them. In that case, they're on their way back here now. So, if we head back without delay, we may make it through AP-5 while they're in transit!"

  Actually, it was an incident in Old Terra's military history-specifically, the opening phases of World War I, four and a half centuries ago-that had made him think of it. Just before the First Battle of the Marne, the Germans, jittery about the Russian threat, had diverted four divisions to the East. Those divisions had ended up missing the decisive battles on both fronts, which had very possibly lost Germany the war. He considered mentioning it, but decided it would take too much time to convey all the background information the nonhumans would need. Instead, he watched as his staffers savored the possibility of a free run home.

  Shaaldaar spoke slowly from his com screen.

  "I want as much as anyone to believe in this possibility, Admiral. But if the Bug command here in Home Hive One did, in fact, recall its battle-line from AP-5 when our attack began, it must also have sent orders to that battle-line to return there when it became clear that the system was doomed, so that even if we couldn't be
stopped here, we could at least be intercepted on our return."

  "You're probably right, Force Leader. And if you are, it's all the more reason for us to depart without delay." Prescott became very brisk. "Commodore Mandagalla, send out orders for the task force to retire on the warp point. Commodore Landrum, it will be necessary for the fighters and gunboats to cover our withdrawal and insure that no Bug scouts are in a position to observe our warp transit. The location of that warp point is a secret I mean to see kept."

  "Aye, aye, Sir," the chief of staff and the farshathkhanaak responded in unison.

  A dispatch boat was waiting in El Dorado.

  For security reasons, GFGHQ, with Prescott's and Zhaarnak's strong support, had decided against deploying the sort of interstellar communications network which would have permitted light-speed message transmission across the star systems of the Prescott Chain. The ICN was the backbone of the command and control systems of major star nations like the Federation and Khanate and had already been of enormous strategic advantage to the Alliance, since the Bugs, with no equivalent of it, were forced to accept far greater delays in communication. The Bugs' offsetting advantage, however, was that by never emplacing the long chains of deep-space relay satellites which sent messages across star systems, or the crewed com stations hovering at each intervening warp point to shuttle courier drones back and forth, or even the navigation buoys which courier drones required to reorient for transit without such com stations, they left no "bread crumbs" behind. There was no trail of installations which might draw a survey force's attention to a warp point, or lead an invasion force along the critical warp lines of their domain.

  If Seventh Fleet had been operating through space the Alliance knew the Bugs had already surveyed, that wouldn't have been a factor. But in this case, the Allies had no idea how much or how little of the Prescott Chain the Bugs might have explored, and so the Strategy Board had decided to take a page from the enemy's book and put up no signposts to help them out. Which was just fine from many perspectives, but meant that Seventh Fleet's communications were far slower and more roundabout than Allied commanders were accustomed to.

  Prescott had detached small, cloaked picket forces in each of the star systems through which he'd passed, both as a security measure to watch his back and also to serve as communications nodes. But such pickets had to have freedom of maneuver to do their jobs, so courier drones couldn't be programmed with known coordinates to reach them. And, for obvious reasons, sending out drones with omnidirectional radio beacons the pickets might have homed in on was . . . contraindicated.

  The only practical solution was to use dispatch boats-actual starships, all large enough to mount cloaking ECM, who played postman between the picket forces. Like the one which had just delivered TF 71's most recent mail.

  Prescott, Mandagalla, Bichet, and Chung studied the data as Riva y Silva's computer downloaded it to the flag bridge's display. Finally, the spook looked up.

  "You were right, Sir."

  Prescott nodded absently. It was conclusive. The AP-5 pickets had observed the arrival of a Bug force there shortly before the standard date of February 2, 2367, when TF 71 had entered Home Hive One. That force matched the "missing" part of the units Andrew had observed in Home Hive One too precisely for coincidence.

  But Prescott was more interested in the second message from the picket commander. One of the picket ships had gotten close enough to observe the Bugs make transit and pinpoint the coordinates of the warp point through which they'd entered. Beside the excitement of that news, the confirmation of his theory was of little moment.

  "They copied everything they included in our dispatches up the Prescott Chain to GFGHQ, as well," Bichet observed, and Prescott nodded.

  "So no matter what happens to us, the Federation will know the locations of the Bugs' closed warp point in AP-5," he agreed with profound satisfaction.

  Mandagalla admired the boss's selflessness, but found herself unable to share it.

  "Uh, Sir, we've got confirmation of where they came from, but there's nothing to suggest that the Bug force from Home Hive One was recalled from AP-5."

  "No, there isn't. But . . ." Prescott did some mental arithmetic. "There wouldn't be. The dispatch boat hasn't been here long, so any later messages, reporting the Bugs' withdrawal, would still be on the way. We should encounter them somewhere between here and AP-5. For now, we'll continue to regard it is a possibility, and act accordingly. That is, we'll proceed at the maximum speed the task force can manage. I want our seriously damaged units taken in tow by Admiral Cole's Wolf 424-class tugs, so they won't slow us down."

  The arrangements were made, and TF 71 fared onward.

  * * *

  Passing through AP-7, two transits from AP-5, they encountered a second dispatch boat. The news it delivered couldn't be suppressed, and the euphoria that spread through Riva y Silva was palpable.

  The staff was no more immune than anyone else. Mandagalla's dark face was alight with joy as she looked up from the readouts on the flag bridge.

  "You were right again, Sir! They've withdrawn from AP-5! They're on their way back to Home Hive One, and-"

  "Unfortunately, Anna, Force Leader Shaaldaar was almost certainly right, too. At some point before the destruction of the last Home Hive One planet, they must've been ordered to resume station in AP-5." Prescott smiled grimly. "A human commander in the same position might have let them continue back to Home Hive One in the hope of a miracle, but I don't think the Bugs believe in miracles. And even if they did, whoever was left in command of their warp point fortifications certainly would have turned them around after we finished off Planet II. If you'll observe the date of this message, it's within the realm of possibility that they've already returned to AP-5."

  "Do you really think they have, Sir?" Bichet asked.

  "No . . . not yet." Prescott produced a very thin smile. "But it's going to be a horse race to see whether we get there first or they get back before we do, I think."

  Bichet looked another question at him, and Prescott shrugged.

  "If we assume that the picket force we destroyed on our way through AP-5 immediately requested reinforcements, and that the Home Hive One mobile forces were sent off as soon as the picket force's courier drone was received there, then we can make a fairly good estimate of the transit time for my hypothetical warp chain by noting when the reinforcements actually arrived in AP-5. Of course, we don't know how many star systems are actually involved, since there's no way for us to predict the distance between warp points in any given system along the way. But what matters for our purposes is how long it would take a courier drone from Home Hive One to reach AP-5."

  He leaned back in his bridge chair and rubbed his eyes wearily.

  "I ran the numbers a second time, assuming that Home Hive One sent the drone recalling their mobile forces at the moment that we first were detected in Home Hive One, and the time required for the drone to make the same trip matches almost exactly. So I think we've got a pretty good idea for the length of the communication loop between Home Hive One and AP-5. And, frankly, it's not as long as I'd hoped it would be."

  His smile, not much of a smile in the first place, died altogether.

  "It's unfortunate that this message has become general knowledge. Anna, I want you to go have a quiet talk with the captain immediately. It's important that we prevent its content from spreading beyond the flagship."

  She gave him an old-fashioned look, and he waved a half-apologetic hand.

  "I recognize the limits of my control over the workings of Rumor Central," he told her wryly. "And I don't expect you or anyone else to perform miracles. But we-and I mean everyone on the staff-has to do everything possible to put a damper on the general excitement. No one will be happier than me if we do manage to get through AP-5 without a fight, but in my opinion it's almost certain that we won't, and I don't want an unrealistic euphoria to bite our morale in the ass when our people find out
it was unjustified."

  "Aye, aye, Sir," a visibly deflated Mandagalla said.

  "In fact," Prescott continued thoughtfully, "given the general giddiness, we should probably keep a lid on the good news everyone seems to have overlooked so far in the excitement, too."

  "Sir?" several staffers queried at once, and Prescott's smile was back.

  "I refer to the message from Fang Zhaarnak which Rear Admiral Heath forwarded with the second dispatch boat. If he holds to his estimated time of arrival, and we do the same, he should enter AP-5 with TF 72 three standard days after we do. So that, ladies and gentlemen, is how long we're going to have to survive in that system unaided."

  After being recalled to protect its System Which Must Be Defended, the Mobile Force had only completed three warp transits before receiving the word that there would shortly be nothing left to protect. So it had reversed course with all possible dispatch, and was now back in Franos, only two transits away from the system where the Enemy survey flotilla had been ambushed . . . and where the destroyers of the System Which Must Be Defended might also be caught, for they must pass through it, and all calculations indicated that they and the Fleet would arrive there at about the same time.

  The Mobile Force would take the picket force here in Franos with it, so a hundred and forty-one ships would be available to close the escape hatch of an Enemy force which had, to a considerable extent, spent itself.
