"Aye, sir," Ensign Lovell said. "Answering engines all stop. Coming about. Brace yourselves." ThePillar of Autumn 's engines sputtered and died.

"Fire missiles at will, Lieutenant."

Rapid-fire thumps echoed though thePillar of Autumn 's hull and a swarm of Archer missiles sped toward the incoming carrier. "MAC gun is hot," Hikowa said. "Booster capacitors ready. Firing in eight seconds, sir." "I must make one small adjustment to your trajectory, Lieutenant," Cortana said.

"Granted," Keyes said. "Firing solution recalculated," Cortana said. "Hang on." Cortana fired thrusters and thePillar of Autumn rotated belly up-brought the majority of her 50mm rotated belly up-brought the majority of her 50mm cannons to bear on the Covenant Seraph fighters underneath her. Overlapping fields of fire wore down their shields-punctured their armored hulls with a thousand rounds, tore through the pilots with a hail of projectiles, and peppered their reactors. Nine puffs of fire dropped behind thePillar of Autumn and vanished into the darkness. "Enemy single ships destroyed," Cortana said. "Approaching firing position." "Cortana, give me a countdown. Lieutenant Hikowa, fire on my mark." Captain Keyes said. "Ready to fire, aye," Lieutenant Hikowa said. Cortana nodded; her trim figure projected in miniature inside the bridge holotank. As she nodded, a time and vanished into the darkness. "Enemy single ships destroyed," Cortana said. "Approaching firing position." "Cortana, give me a countdown. Lieutenant Hikowa, fire on my mark."

As she nodded, a time display appeared, the numbers counting down rapidly. Keyes gripped the edge of the command chair, his eyes glued to the countdown. Three seconds, two, one . . . "Mark."

"Firing!" Hikowa answered.

A triple flash of lightning saturated the forward view screen and bled in from the viewport; three white-hot projectiles crossed the black distance between thePillar of Autumn and the Covenant carrier. Along the side of the carrier, motes of light collected as they rebuilt the charges of their plasma weapons. Archer missiles were pinpoints of exhaust in the distance; the carrier's pulse lasers fired and melted a and the Covenant carrier.

Captain Keyes floated in free fall for a heartbeat, then landed awkwardly on the deck. The crenellated rolled to starboard and dove. Captain Keyes floated in free fall for a heartbeat, then landed awkwardly on the deck. The crenellated surface of an asteroid appeared on their port camera-meters away-then vanished.

Captain Keyes was grateful that he never had time to initialize thePillar of Autumn 's AI. Cortana performed superbly. The trio of blazing MAC rounds struck the carrier. The shield flashed once, twice. The third round got 's AI. Cortana performed superbly. The trio of blazing MAC rounds struck the carrier. The shield flashed once, twice. The third round got through-gutting the ship from stem to stern.

The carrier spun sideways. Her shields stuttered once, trying to reestablish a protective screen. A hundred Archer missiles struck, cratered the hull, blossomed into fire and sparks and smoldering metal. The alien carrier listed and crashed into the asteroid thePillar of Autumn had just narrowly avoided. It had just narrowly avoided. It stuck there, hull broken and cracked. Columns of fire blossomed from the shattered vessel. Captain Keyes sighed. A victory. The Spartans, however, would not be taking that ship into Covenant s.p.a.ce. It wasn't going anywhere. "Cortana, mark the location of the destroyed ship and the asteroid. We may have a chance to salvage her later." "Yes, Captain." "Ensign Lovell," Captain Keyes said, "turn us around and give me best speed to rally point Zulu." Lovell tapped the thrusters and rotated thePillar of Autumn to relative s.p.a.ce normal with Reach. The to relative s.p.a.ce normal with Reach. The rumble of the engines shook the decks as the ship accelerated in-system.

"ETA twenty minutes at best speed, sir." The battle for Reach could be over by the time he got there. Captain Keyes wished he could move through Slips.p.a.ce for short, precision jumps like the Covenant. That carrier had materialized a kilometer behind thePillar of Autumn . If he had that kind of accuracy, he could be at the rally point now-and be of some use. Any attempt to jump in-system, however, would be foolish at best. At worst, it would be a . If he had that kind of accuracy, he could be at the rally point now-and be of some use. Any attempt to jump in-system, however, would be foolish at best. At worst, it would be a fatal move. Jump targets varied by hundreds of thousands of kilometers. Theoretically, they could reenter normal s.p.a.ceinside Reach's sun. "Cortana, give me maximum magnification on the fore cameras." "Aye sir," she said. The view on the forward screen zoomed in-jumped and refocused on planet Reach. Twenty thousand kilometers from the planet, a cl.u.s.ter of a hundred UNSC ships collected at rally point Reach's sun. "Cortana, give me maximum magnification on the fore cameras." "Aye sir," she said. The view on the forward screen zoomed in-jumped and refocused on planet Reach. Twenty thousand kilometers from the planet, a cl.u.s.ter of a hundred UNSC ships collected at rally point Zulu: destroyers, frigates, three cruisers, two carriers-and three refit and repair stations hovering over them . . . waiting to be used as sacrificial shields. "Fifty-two additional UNSC warships inbound to rally point Zulu," Cortana reported.

"Shift focus to section four by four on-screen, Cortana. Show me those Covenant forces." The scene blinked and transferred to the approaching Covenant fleet. There were so many ships Captain Keyes couldn't estimate their numbers.

"How many?" he asked. "I count three hundred fourteen Covenant ships, Captain," Cortana replied. Captain Keyes couldn't tear his gaze away from the ships. The UNSC only won battles with the Covenant when they outnumbered the enemy forces three to one . . . not the other way around.

They had one advantage: the MAC orbital guns around Reach-the UNSC's most powerful nonnuclear weapon. Some called them "Super" MAC guns or the "big stick." Their linear accelerator coils were larger than a UNSC cruiser. They propelled a three-thousand-ton projectile at tremendous speed, and could reload within five seconds. They drew power directly from the fusion reactor complex planetside. "Pull back the camera angle, Cortana. Let me see the entire battle area."

The Covenant ships accelerated toward Reach. The fleet at rally point Zulu fired their MAC guns and missiles. The orbital Super MAC guns opened fire as well-twenty streaks of white hot metal burned across the night.

The Covenant answered by launching a salvo of plasma torpedoes at the orbital guns-so much fire in s.p.a.ce that it looked like a solar flare.

Deadly arcs of flame and metal raced through s.p.a.ce and crossed paths.

The engines of the three refit stations flared to life and the platelike ships moved toward the path of the flaming vapor.

A plasma bolt caught the edge of the leading station-fire splashed over its flat surface. More bolts. .h.i.t, and the station melted, sagged, and boiled. The metal glowed red, then white-hot, tinged with blue.

The other two stations maneuvered into position and shielded the orbital guns from the fiery a.s.sault. Plasma torpedoes collided with them and sprayed plumes of molten metal into s.p.a.ce. After a dozen hits, clouds of ionizing metal enveloped the place where the three stations had been.

They had been vaporized.

The last of the Covenant plasma hit the haze-scattered, absorbed, and made the cloud glow a h.e.l.lish orange.

Meanwhile, the fleet's opening salvo and the Super MAC rounds. .h.i.t the Covenant fleet.

The smaller ship-based MAC rounds bounced off the Covenant shields-it took three or more to wear them down.

The Super MAC rounds, however, were another story. The first Super MAC sh.e.l.l hit a Covenant destroyer. The ship's shield flashed and vanished-the remaining impact momentum transferred to the ship-the hull rippled and shattered into a million fragments.

Four nuclear mines detonated in the center of the Covenant fleet. Dozens of ships with downed shields flared white and dissolved.

The other ships however, shrugged off the damage; their shields burned brilliant silver, then cooled.

The surviving Covenant vessels advanced in-system-a third of their number were left behind . . . burning radioactive hulks or utterly destroyed by the Super MAC rounds.

Plasma charges collected on the lateral lines of the Covenant ships. They fired. Fingers of deadly energy reached across s.p.a.ce . . . toward the UNSC fleet.

One Covenant ship sat in the center of the pack, a gigantic vessel, larger than three UNSC cruisers. White-blue beams flashed from its prow-a split second later five UNSC vessels detonated.

"Cortana . . . what the h.e.l.l was that?" Keyes asked. "Lovell, push those engine superchargers as hot as you can make them."

"Running at three hundred ten percent, sir," Lovell reported. "ETA fourteen minutes."

"Replaying and digitally enhancing video record," Cortana said.

She split the screen and zoomed in on the huge Covenant ship, replaying the video as the large ship fired. The Covenant energy beams looked like pulse lasers . . . but tinged silver white, the same scintillation effect that they'd seen when their shields were hit.

Cortana switched back to view the doomed UNSC destroyerMinotaur . The lance of energy was needle-thin. It struck the vessel on A deck, aft, near the reactor. Cortana pulled the view back and slowed the record frame by frame-the beam punctured through the entire ship, emanating below H deck by the engines. . The lance of energy was needle-thin. It struck the vessel on A deck, aft, near the reactor. Cortana pulled the view back and slowed the record frame by frame-the beam punctured through the entire ship, emanating below H deck by the engines.

"It drilled through every deck and both sets of battleplate," Captain Keyes murmured.

The beam moved through theMinotaur , slicing a ten-meter-wide swath. , slicing a ten-meter-wide swath.

"Projected beam path cut through theMinotaur 's reactors," Cortana said. 's reactors," Cortana said.

"A new weapon," Captain Keyes said. "Faster than their plasma. Deadlier, too."

The large Covenant ship veered off course and accelerated away from the battle. Perhaps it didn't want to risk getting too close to their orbital MAC guns. Whatever the reason, Keyes was grateful to see it withdraw.

The UNSC forces slowly scattered. Some launched missiles to intercept the plasma torpedoes, but the high-energy explosives did nothing to the stop the superheated bolts. Fifty UNSC ships went up like flares, burning, exploding, falling toward the planet.

The orbital Super MAC guns fired-sixteen hits and sixteen Covenant ships were blasted into flame and glittering fragments.

The Covenant fleet split into two groups: half accelerated to engage the dispersing UNSC fleet; the remainder of their ships arced upward relative to the plane of the system. That group maneuvered to get a clear shot around the cloud of vaporized t.i.tanium from the refit stations. They were going to target the orbital guns.

Plasma charges collected along their sides. The orbital guns fired. The super-heavy rounds tore through the clouds of ionized metal vapor, leaving whorls and spirals in the haze. They impacted eighteen incoming Covenant ships-ripped through them like tinfoil, with enough momentum to pulverize their hulls. Six Covenant ships cleared the interfering cloud of vapor. They had a clear shot. The Super MAC guns fired again. Plasma erupted from the sides of the nearby Convent ships. The Super MAC rounds. .h.i.t the vessels and obliterated the enemy. The streams of plasma, however, had already launched. They streaked toward the orbital guns- impacted and turned the installations into showers of sparks and molten metal.

When the haze cleared, fifteen of the Super MAC orbital installations remained intact . . . five had been vaporized. The Covenant ships engaging the fleet turned and fled on an out-system vector. The remaining UNSC ships did not pursue. "Incoming orders, sir," Lieutenant Dominique called out. "We're being ordered to fall back and regroup." Keyes nodded. "Cortana," he said, "can you give me damage and casualty estimates for the fleet?" Her tiny holo image coalesced in the display tank. "Yes, Captain," she said. She c.o.c.ked an eyebrow at him. "Are you sure you want the bad news?" Damage estimates scrolled across his personal screen. They had taken heavy losses-an estimated twenty ships remained. Nearly one hundred shattered and burning UNSC vessels floated, lifeless, in the combat area.

Captain Keyes realized that he was holding his breath. He exhaled. "That was too close," he murmured. "It could have been closer, Captain," Cortana whispered. He watched the retreating Covenant. Once again-it was too easy. No . . . it had been anything but "easy" for the UNSC forces, but the Covenant were certainly giving up far earlier than in any previous battle. The aliens had never stopped once they engaged an enemy. Except at Sigma Octa.n.u.s, he thought.

"Cortana," Captain Keyes said. "Scan the poles of planet Reach and filter out the magnetic interference." The view screen snapped to the Reach's northern pole. Hundreds of Covenant dropships streamed toward the planet's surface.

"Get FLEETCOM HQ online," he ordered Lieutenant Dominique. "Copy this message to the Fleet Commander, as well." "Aye, sir," Lieutenant Dominique said. "Channel connected."

"Tell them they're being invaded. Dropships inbound at both poles." Dominique sent the message, listened a moment, then reported, "Message received and acknowledged, sir."

The Super MAC guns pivoted and fired-shattering dozens of the Covenant dropships in the sh.e.l.ls'

supersonic wake. The remains of the UNSC fleet split into two groups, moving toward either pole. Missiles and MAC guns fired and blasted the dropships to bits. The poles were punctuated with thousands of meteoroids as the bits of hull burned up in the atmosphere.

Hundreds must have gotten through, Keyes thought. Reach had been invaded.

"Incoming distress signal from FLEETCOM HQ planetside, sir," Lieutenant Dominique said, his voice breaking. "On speakers," Captain Keyes said. "There are thousands of them. Grunts, Jackals, and their warrior Elites." "There are thousands of them. Grunts, Jackals, and their warrior Elites."The transmission broke into static."They have tanks and fliers. Christ, they've breached the perimeter. Fall back! Fall back! If anyone can hear this: the Covenant is groundside. Ma.s.sing near the armory . . . they're-" White noise filled the speakers. Captain Keyes winced as he heard screams, bones snapping, an explosion. The transmission went dead. White noise filled the speakers. Captain Keyes winced as he heard screams, bones snapping, an explosion. The transmission went dead.

"Sir!" Lieutenant Hall said. "The Covenant fleet has altered their outbound trajectory. . . . they're turning." She rotated to face the Captain. "They're coming in for another attack."

Captain Keyes stood straighter and smoothed his uniform. "Good." He addressed the crew in the calmest voice he could muster. "Looks like we're not too late after all."

Ensign Lovell nodded. "Sir, ETA to rally point Zulu in five minutes."

"Remove all missile safety locks," Captain Keyes ordered. "Get our remote-piloted Longsword into the launch tube. And make sure our MAC gun capacitors and boosters are hot."

Captain Keyes pulled out his pipe. He lit it and puffed.

The Covenant were, of course, after the orbital guns. Their suicidal frontal charge-while almost effective enough-had been just another diversion. The real danger was on the ground; if their troops took out the fusion generators, the Super MAC guns would be so much floating junk in orbit.

"This is bad," he muttered to himself.

Cortana appeared on the AI pedestal near the NAV station. "Captain Keyes, I'm picking up another distress signal. It's from the Reach s.p.a.ce dock AI. And if you think this-" she gestured at the incoming Covenant fleet on screen "-is bad, wait until you hear this. It gets worse."

CHAPTER THIRTY-FOUR.

0558 Hours, August 30, 2552 (Military Calendar) / UNSCPillar of Autumn , Epsilon Eridani System , Epsilon Eridani System The mission had just encountered another snag.

It never entered the Master Chief's mind that he would fail to achieve his objectives. He had to succeed. Failure meant death for not only himself, but for all the Spartans . . . every human.

He stood at the view screen in the cargo bay and reread the priority Alpha transmission Captain Keyes had sent down: Alpha priority channel: To Fleet Admiralty from REACH s.p.a.ce Dock Quartermaster AI8575 (a.

k.a. Doppler) / /triple-encryption time-stamped public key: red rover red rover/ /start file/ IMMEDIATE ACTION REQUIRED.

/end file/ He replayed the distress call from Reach's groundside FLEETCOM HQ.

" . . . They've breached the perimeter. Fall back! Fall back! If anyone can hear this: the Covenant is groundside. Ma.s.sing near the armory . . . they're-"

The Master Chief copied these files and sent them over his squad's COM channel. They had a right to know everything, too.

There was only one reason the Covenant would launch a ground invasion: to take out the planetary defense generators. If they succeeded, Reach would fall.

And there was only one reason why the Covenant wanted the shipCirc.u.mference -to plunder its NAV database-and find every human world, including Earth. -to plunder its NAV database-and find every human world, including Earth.

Captain Keyes appeared on the view screen. He held his pipe in one hand, squeezing it so tight his knuckles were white. "Master Chief, I believe the Covenant will use a pinpoint Slips.p.a.ce jump to a position just off the s.p.a.ce dock. They may try to get their troops on the station before the Super MAC guns can take out their ships. This will be a difficult mission, Chief. I'm . . . open to suggestions."

"We can take care of it," the Master Chief replied.

Captain Keyes' eyes widened and he leaned forward in his command chair. "How exactly, Master Chief?"

"With all due respect, sir, Spartans are trained to handle difficult missions. I'll split my squad. Three will board the s.p.a.ce dock and make sure that NAV data does not fall into the Covenant's hands. The remainder of the Spartans will go groundside and repel the invasion forces."

Captain Keyes considered this. "No, Master Chief, it's too risky. We've got to make sure the Covenant doesn't get that NAV data. We'll use a nuclear mine, set it close to the docking ring, and detonate it."

"Sir, the EMP will burn out the superconductive coils of the orbital guns. And if you use thePillar of Autumn 's conventional weapons, the NAV database may still survive. If the Covenant search the wreckage-they may obtain the data." 's conventional weapons, the NAV database may still survive. If the Covenant search the wreckage-they may obtain the data."

"True," Keyes said, and tapped his pipe thoughtfully on his chin. "Very well, Master Chief. We'll go with your suggestion. I'll plot a course over the docking station. Ready your Spartans and prep two dropships. We'll launch you-" he consulted with Cortana "-in five minutes."

"Aye, Captain. We'll be ready."

"Good luck," Captain Keyes said, and snapped off the view screen. Luck. The Master Chief always had been lucky. He'd need luck more than ever this time. He turned to face the Spartans . . . his Spartans. They stood at attention. Kelly stepped forward. "Master Chief sir, permission to lead the s.p.a.ce op, sir." "Denied," he said. "I'll be leading that one." He appreciated her gesture. The s.p.a.ce operation would be ten times more dangerous than the ground op. The Covenant would outnumber them ten to one-or more-but the Spartans were used to taking the fight against numerically superior enemies. They had always won on the ground. The extraction of theCirc.u.mference database, however, would be in vacuum and zero gravity-and they database, however, would be in vacuum and zero gravity-and they might have to fight their way past a Covenant warship to reach the objective. Not exactly ideal conditions. "Linda and James," he said. "You're with me. Fred, you're Red Team Leader. You'll have tactical command of the ground operation." "Sir!" Fred shouted. "Yes, sir." "Now make ready," he said. "We don't have much time left." The Master Chief regretted his unfortunate choice of words. The Spartans stood a moment. Kelly called out, "Attention!" They snapped to and gave the Master Chief a crisp salute. He stood straighter and returned their salute. He was intensely proud of them all. The Spartans scattered and gathered their gear, racing for the dropship bay. The Master Chief watched them go. This was the mission the Spartans had been tempered for in mission after mission. It would be their finest moment . . . but he knew that it might also be their last moment. Chief Mendez had said that a leader would be required to spend the lives of those under his command.

The Master Chief knew he would lose comrades today-but would their deaths serve a necessary purpose . . . or would they be wasted?

Either way, they were ready.

John tapped the thrusters and rotated the Pelican dropship 180 degrees. He pushed the engines to full power to brake their forward momentum. ThePillar of Autumn had dropped them while she had been cruising at one-third full speed. had dropped them while she had been cruising at one-third full speed.

They'd need every millimeter of the ten thousand kilometers between them and the docking station to slow down.

The Master Chief had taken the Spartan's modified Pelican, rigged with explosives. The station would be locked down-every airlock sealed. They'd have to blast their way in.

He glanced aft. Linda checked one of the three sniper rifle variants she had brought. James inspected his thruster pack.

He had picked Linda because no other single Spartan was as efficient at long-range combat. And that's what the Master Chief wanted:long -range combat. If it came to hand-to-hand combat in zero gee with hordes of Covenant troopers . . . even his luck wouldn't hold out too long. -range combat. If it came to hand-to-hand combat in zero gee with hordes of Covenant troopers . . . even his luck wouldn't hold out too long.

He had picked James because James had never quit. Even when his hand had been burned off, he had shrugged off the shock-at least for a while-and helped them dispatch the Covenant behemoths on Sigma Octa.n.u.s IV. The Master Chief would need that kind of determination on this mission.

He took a long look out the front of the Pelican. Their sister dropship initiated a burn and hurtled toward Reach.

Kelly, Fred, Joshua . . . all of them. Part of him longed to join them in the ground action.

The radar panel blinked a proximity warning; the Pelican was one thousand kilometers from the docking ring.

The Master Chief tapped the thrusters to align the dropship. He squelched the proximity alert.

The alert immediately re-sounded. Strange. He reached for the squelch again-then stopped as he saw the s.p.a.ce around the Pelican change. Motes of green light appeared, pinpoints at first, which swelled like bruises on velvet black s.p.a.ce. The green smears lengthened, compressed, and distorted the stars.

-a Slipstream entry point. The Master Chief cut the Pelican's engines, slowing them for impact. A Covenant frigate materialized a kilometer from the dropship's nose. Its prow filled their view screen.
