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.
