Jack Campbell: Leviathan

“Those wouldn’t stand a chance even if they could see the dark ships,” Geary said. “We may not be able to catch the dark ships, but we can stay on their tails.” He tapped a comm control. “All units in Task Force Dancer, immediate execute accelerate to point two five light speed, come port two five degrees, down zero three degrees.”

“Are we going to chase them through the hypernet gate?” Desjani asked.

“If we have to,” Geary said. “We have to find their base, wherever it is.” He checked the fuel cell status on his ships and let out an angry breath. “I’ll have to leave our destroyers here if we do that. Their fuel supplies are getting too low. Now, let’s get the word out to everyone here,” Geary added, his mood and his voice grim. He could see the many defenses at Varandal, the numerous warships and installations, all at standby readiness because the war with the Syndics had at last ended. “Why aren’t they reporting peacetime readiness instead of standby?” Geary grumbled.

“Because nobody but you remembers what peacetime readiness is,” Desjani reminded him. “And if the attack on Indras by those dark ships causes the Syndics to retaliate, this peace business may already be over with before the rest of us can figure out what it means.”

“I hope you’re wrong about that. At least if the Syndics attack our defenses, we will be able to see them .” Even after experiencing on these ships how secret software modifications had left Alliance sensors unable to see the dark ships, it was still hard to grasp that everything else in this star system would be totally unaware of the dark ships that were passing through. Many of those defenses were too far off to have seen the dark ships yet regardless, of course, let alone the more recent arrival of Geary’s ships. Light only moved at about eighteen million kilometers a minute, so with distances inside a star system measured in hundreds of millions or billions of kilometers, even light took a while to get places.

But other defenses, other ships closer to this edge of the star system, should have seen the dark ships by now. If their own software were not blinding them to the presence of the hostile forces.

“What you are about to do will raise hell,” Desjani commented.

“I know that,” he replied. “Are you advising me not to do it?”

“No.” Her grin was fierce. “I’m looking forward to it.”

Geary couldn’t help a tense, humorless smile in return, then composed himself, touched the transmit command, and began sending the message he had been rehearsing during the long days in jump space since leaving Atalia. “All units in the First Fleet, there are hostile forces in this star system that your software is blocking all sight of. These are not, repeat not, enigma warships. Our best estimate is that these are fully automated combatants that have slipped whatever controls were supposed to limit their actions.”

He paused a moment to let that sink in before continuing. “We have engaged in combat with those forces at Atalia, where they, without provocation or warning, attacked Alliance as well as civilian shipping and caused extensive destruction and loss of life. These hostile warships have already attacked Alliance warships and killed Alliance personnel. My task force is in pursuit of these ships, which are currently en route to Varandal’s hypernet gate. Based on their actions at Indras and Atalia, it must be assumed that any Alliance or civilian ships they encounter will be attacked and destroyed.

“Attached is a set of software patches you are to install on your ships. Disable automatic updates and permit no other updates until I personally authorize it. Your combat, maneuvering, sensor, database, and other systems contain hidden subroutines that mask the presence of the hostile warships. Once you have implemented the software patches we are sending, we will forward identifying information on the hostile warships. If we sent that information now, your own communications systems would strip out all traces of anything related to the hostile warships. These software patches are personally authorized by me as commander of the First Fleet. Geary, out.”

He tapped in another command, this one aimed at the two destroyers on picket duty at the hypernet gate. “ Mortar , Serpentine , this is Admiral Geary. There are hostile warships in overwhelming force approaching your orbit. You cannot detect those warships until the attached software patches are fully applied to all of your systems. Immediate execute, accelerate to point two light speed and proceed on a vector toward Ambaru Station while applying the patches. Geary, out.”

“That should have them nowhere nearby when the dark ships reach the gate,” Geary told Desjani.

“If they follow that order,” she said. “And if they don’t head back to the gate as soon as they apply the patches. If they do. Those two destroyers are not part of the First Fleet. They belong to the Varandal local self-defense forces.”

“I know that.”

“You told them that enemy forces were approaching,” Desjani added implacably. “They’re not going to run.”

“I didn’t tell them to run,” Geary insisted. “I told them to head for another orbital location while fixing their system software.”

“Same difference, Admiral,” she said. “You’d better get Admiral Timbale to send them those orders if you want any chance of their being obeyed. Ambaru Station is currently three and a half light-hours from us, and the destroyers are about five light-hours from Ambaru, so if Timbale sends maneuvering orders to the two destroyers within a few hours after we warn him, there is enough time”

“I’m calling Timbale now,” Geary replied. Another command entered, then he spoke with quiet intensity. “Admiral Timbale, this is Admiral Geary. Be advised that there are hostile forces operating within Alliance space, and that hidden subroutines in our own software are preventing us from seeing those forces. A mixed force of hostile battle cruisers, heavy cruisers, and destroyers inflicted catastrophic damage at Indras Star System, damage which the Syndicate Worlds’ authorities at Indras blame on the Alliance. Courier ships must be sent as soon as possible to alert fleet headquarters and border star systems that the attack at Indras may trigger direct retaliatory attacks on Alliance star systems by the Syndicate Worlds. The same hostile warships caused extensive loss of life and property at Atalia and conducted a deliberate and unprovoked attack on the Alliance picket ship watching Atalia, destroying it without warning. They also attacked my ships, destroying one battle cruiser, a light cruiser, and two destroyers, and inflicting serious damage on other Alliance warships. I have reason to believe that these hostile warships are completely automated, with no human crews. They are very heavily armed, very maneuverable, and a force of them is currently traversing Varandal en route to the hypernet gate. I am in pursuit of them and will engage them again if possible. I have ordered the two destroyers on duty near the gate to reposition, but do not know if they will comply with orders from me. Attached is a set of software patches that will allow you to see the hostile warships and retain information about them in your databases. Geary, out.”

He sat back, feeling Dauntless accelerate as her main propulsion drove her in pursuit of the dark ships, the other warships of the task force arrayed around Dauntless and matching her movements. There was nothing else to do now. Space was too big for anything else to be done. All he could do was wait, and react when he finally received replies to his messages, which would take hours to reach the ships and places to which they had been sent, and hours more for replies to cross the same immense distances.
