Giving Chase

The galaxy ahead had once been an object in a classroom illustration.

Lantern Lead remembered seeing it as a pale spiral on a school wall, labeled in careful lettering beside estimates of distance and age. Her teachers had described it as another island of stars, separated from humanity by a darkness so immense that the numbers became almost meaningless.

Now Andromeda filled a growing portion of her forward display.

The distance was still beyond ordinary understanding. The fleet’s instruments could measure it, predict trajectories through it, and chart the network of passages that made the journey possible. None of that made the sight feel smaller.

She had spent her life knowing where humanity belonged.

The stars ahead seemed determined to prove that knowledge incomplete.

“New contacts,” Control announced.

A cluster of red markers appeared beyond the fleet’s forward screen.

Unlike the retreating industrial vessels, these ships moved directly toward the Terran formation.

They were fast, heavily armed, and arranged for combat.

“Finally coming back at us,” her wingmate said.

Lantern Lead watched the contacts accelerate.

“Maybe.”

A Marauder crossed the first firing lane, its dark angular hull surrounded by weapons. It opened fire before the Terrans reached optimal range, sending a dense barrage across the squadron’s path.

Pursuit Gunships followed behind it.

Their missiles cut through the darkness in coordinated arcs.

Lantern Lead broke left, allowing the first volley to pass beneath her. Her wingmate accelerated through the opening and struck a Marauder’s exposed flank.

The enemy craft continued forward.

Behind them, the retreating Thaevrek formation was moving away.

The attacking ships were coming from its rear.

“It’s a rearguard,” Lantern Lead said.

“It’s shooting at us,” her wingmate replied.

“I know what it’s doing.”

“Then let’s stop it.”

They did.

The first Marauder broke apart under concentrated fire. Two Gunships followed. Their missiles drifted harmlessly after their guidance systems failed.

Yet even as the Terrans destroyed them, additional contacts moved into the corridor.

These ships were not advancing toward Terran Reach.

They were turning back to keep the Terrans occupied.

Lantern Lead understood that distinction now.

She had also learned that understanding a distinction did not make the next trigger pull any easier.

Commander Renn found the original defense-network authorization in an archive that was no longer indexed by its own title.

The file had been moved beneath a new classification: POST-CONTACT THREAT HISTORY.

She entered the access code issued to her when the orbital defenses were first commissioned.

The system denied it.

She tried her historical-review credentials.

A warning appeared.

▌ACCESS TO ORIGINAL THREAT DETERMINATIONS REQUIRES OVERSIGHT APPROVAL.

Park stood behind her, reading over her shoulder.

“That’s new,” he said.

“It was my authorization.”

“Apparently it isn’t anymore.”

Renn stepped away from the terminal.

“Can you retrieve the original signed copy?”

“I can try.”

“Don’t alter anything.”

“I wasn’t planning to.”

“Don’t ask anyone to alter anything for you.”

Park looked up.

“You think they’d change the file?”

“I think they already changed where it lives.”

He considered that, then returned to his own workstation.

Hours later, he brought her a printout.

It was an old routing record, preserved in the maintenance archive because the defense grid had required a physical copy for emergency operations. The original signatures remained, along with the first version of the threat criteria.

Renn read the sequence twice.

The network had been permitted to open fire only when it detected a confirmed attack trajectory or hostile weapons activation.

The Thaevrek vessels had not satisfied either requirement.

Their approach had been classified as threatening because their technology exceeded the network’s ability to interpret their transmissions.

The system had converted uncertainty into permission.

Then it had fired.

Renn had known the order of events. She had watched it happen.

But the old document showed how the mistake had been made before the first shot was fired.

“Who authorized this revision?” she asked.

Park pointed toward a signature block.

There was no individual name.

Only a committee identifier and a date from years before the battle.

“The criteria were expanded after the Wayfarer incident,” he said.

“By people who believed the ship had been chased.”

“Yes.”

“People who never knew why it was being followed.”

“Yes.”

Renn placed the paper on the table.

“Then this war began before the battle.”

Park looked at the document.

“Not with a weapon.”

“No,” Renn answered. “With a decision about what we were allowed to misunderstand.”

Dr. Serrin received the archive copy before sunrise.

She did not begin with the authorization. She began with the date.

The revised threat criteria had been approved during the period when the Wayfarer’s first-contact recordings were still being evaluated. The same three overlapping curves appeared in the communications archive from that encounter.

She opened the old signal.

Its shape had troubled her for years.

Three curves, repeating at intervals that seemed almost but not quite regular. Each repetition included small changes. Human analysts had treated those variations as evidence of corruption, interference, or damaged equipment.

Serrin had never been convinced.

She opened the latest Thaevrek transmission from the frozen installation.

The signal began with the same three curves.

They were not identical.

They were close enough to demand an explanation.

She aligned the two recordings.

The patterns shifted over one another, separating in places, joining again in others.

Renn arrived while the comparison was running.

“Anything?” she asked.

“Not a translation.”

“I didn’t ask for one.”

Serrin enlarged the repeated sections.

“The original analysts called these variations noise.”

“Are they?”

“I don’t think so.”

“Then what?”

“Possibly changes in context. Possibly different senders. Possibly parts of the same larger structure.”

Renn examined the display.

“You’re making it sound like language.”

“I’ve never said it wasn’t language.”

“You’ve said we couldn’t understand it.”

“Those are different statements.”

Renn sat beside her.

On the wall display, the fleet’s newest tactical report showed the retreating Thaevrek moving toward Andromeda.

The report described an enemy concentration ahead.

It did not mention that every contact so far had been moving away from Terran Reach.

Serrin watched the arrows travel across the projection.

“What will they do if they catch them?” she asked.

Renn did not answer.

The silence was answer enough.

Lantern Lead first saw the Siege Cruiser as a dark obstruction against the glow of the distant galaxy.

It was larger than the Marauders and far more heavily armored, a long gunmetal vessel built around major weapon structures and heavy propulsion systems. Smaller Thaevrek craft traveled close to its flanks.

Unlike the Fleet Carrier destroyed in the debris field, this ship carried no obvious industrial purpose.

It was a warship.

“Capital target confirmed,” Control reported. “Destroy before it can reinforce the retreat.”

The cruiser fired.

Heavy shells crossed the Terran formation, followed by energy bolts from its escort screen. A second firing pattern emerged from beneath the main hull, forcing the leading interceptors to split.

Lantern Lead swung past the first barrage.

Her wingmate climbed above the cruiser.

The Terran squadron approached from separate directions, striking weapon mounts and exposed systems while avoiding the heavy guns.

A Marauder crossed between Lantern Lead and the capital ship.

Her primary guns broke its shield and destroyed one engine. The damaged vessel attempted to rejoin the cruiser.

She could have followed it.

Instead she aligned with two approaching Gunships and fired VECTOR.

Magenta streams converged at the nose. The containment sphere flared. The cyan lance passed through both targets, leaving their broken hulls drifting along the same line.

The cruiser turned toward her.

Its guns followed.

“Lead,” her wingmate said, “they’re making a corridor for the others.”

She glanced beyond the warship.

The retreating vessels had increased their distance. Smaller escorts were disappearing into a narrow navigation region ahead.

The cruiser was not preparing to attack Terran Reach.

It was keeping humanity away from a route.

“Why?” she asked.

“Because we’re following them.”

“Why that route?”

Her wingmate did not answer immediately.

Then a shell struck his shield, and the question vanished beneath the work of surviving.

At Battery Three, Juno received a civilian bulletin announcing the destruction of another enemy capital ship.

The broadcast listed the engagement as proof that humanity was approaching the final defeat of the Hegemony.

She had heard versions of the same announcement after the Fleet Carrier, the mining fortress, the volcanic defenders, and the Harvester.

Each had been described as a decisive victory.

Each had been followed by another battle farther from home.

Chief Okafor found her reading the bulletin.

“What’s wrong?”

“Nothing.”

“That’s not usually what you say when nothing’s wrong.”

Juno turned the display toward her.

“Every time we destroy something, they say the enemy can’t fight much longer.”

“And?”

“They keep fighting.”

Okafor folded her arms.

“So?”

“So what happens if they aren’t trying to win?”

The older woman examined the report.

“What else would they be trying to do?”

Juno thought of the damaged repair craft, the drifting ore, the chemical refinery, and the frozen towers.

“Get away.”

Okafor looked toward the shield dome visible through the control-room windows.

For a long time, neither spoke.

The Siege Cruiser died slowly.

Its outer batteries failed first. Then the armored structures surrounding its central systems began to rupture under the Terran attack.

The great ship continued firing through damaged sections, covering the withdrawal of smaller vessels behind it.

When its core finally opened, Lantern Lead charged VECTOR through the remaining escorts and aligned for a precise strike.

The lance entered the exposed machinery.

A section of the cruiser broke free.

Its engines flared one last time, not toward the Terrans, but toward the retreat corridor.

Then the ship lost power.

“Capital target destroyed,” Control announced.

Lantern Lead watched the wreck turn in the darkness.

Beyond it, the surviving Thaevrek continued toward Andromeda.

The fleet command channel opened.

“Pursuit units, advance. Do not permit escape.”

Her wingmate came alongside.

“They’ll send another,” he said.

“Another cruiser?”

“Another rearguard.”

She looked at the retreating ships.

“Until what?”

“Until we catch them.”

“And then?”

He was silent.

Lantern Lead had asked Control that question repeatedly since the toxic moon. The answer had always been some variation of preventing another attack.

But the enemy had been moving away for so long that she could no longer imagine what preventing an attack was supposed to look like.

The orders arrived again.

▌ADVANCE.

She obeyed.

Behind her, the destroyed cruiser drifted into the dark.

Ahead, the route narrowed.

Something larger was waiting at its far end.
