The first shots came down from the axis, spraying bits of the ceramic roadway up in front of the lead cart. Bull tried to bend his head back far enough to see whether the attack was coming from the transfer point itself or a barricade closer in.
“Juarez!” Verbinski shouted. “Cover us.”
“Yes, sir,” a voice called from one of the back carts. Bull swiveled the mech enough to look over his shoulder. On the third cart back, one of the Martian marines was lying on his back, a long scoped rifle pointing up. He looked like he was napping until the rifle fired once. Bull tried to look up again, but the mech prevented him. He took out his hand terminal and used its camera like a mirror. High above them, a body was floating in the null-g zone, a pink cloud of blood forming around its waist.
“One less,” Verbinski said.
The firing continued as they took the ramp at speed. The semi-adhesive ripping of the tires against the deck changed its tone as less and less weight pressed against them. Bull felt his body growing lighter in its brace. The edge of the ramp was a cliff now, looking down almost a third of a kilometer to the floor of the drum below. Ashford’s men were above them, but not so far now that Bull couldn’t see the metal barricades they’d welded to the walls and deck. He was painfully aware of being the highest target. His neck itched.
Two heads popped up from behind the barricades. The muzzle flashes were like sparks. The Martian’s rifle barked behind him, and one of the attackers slumped down, the other retreating.
“Okay,” Bull said. “This is as close as we get without cover.”
Corin spun the cart nose in to the wall and slipped out, taking cover with Verbinski behind it while the next cart came ahead mirroring her. They were in microgravity here. Maybe a tenth of a g. Maybe less. Bull had to turn the magnets on in his mech’s feet to keep from floating away. By the time he’d gotten off the cart, the fighting was already far ahead of him. He drove the mech forward, marching up past the improvised barricades of the carts. The closest of them was less than ten meters from the first of Ashford’s barricades, and Jim Holden, Corin, and one of the Earthers were already pressed against the enemy’s cover, ducking to the side, firing, and falling back. The smell of spent gunpowder soured the air.
“Where’s Naomi?” Bull shouted. He didn’t have a clear idea whether any of the technical staff in there besides Ruiz were still loyal to Pa, and if they got their only real engineer killed before they made it into engineering, he was going to be pissed. Something detonated behind the barrier and two bodies pinwheeled out into the empty air. The light was behind them, and he couldn’t tell if they were his people or Ashford’s. At the last of the carts, he stopped. The battle was well ahead of him now, almost at the transfer point itself. That was good. It meant they were winning.
A thin man was still at the cart’s wheel. At a guess, he was in his early twenties, brown skin and close-cropped hair. The hole in his chest had already stopped bleeding and his eyes were empty. Bull felt a moment’s regret and pushed it away. He’d known. They’d all known. Not just coming to this fight, but when they’d put their boots on the Behemoth and headed out past the farthest human habitation, they’d known they might not make it back. Maybe they’d even known that the thing that killed them might not be the Ring, but the people who’d gone out alongside them. People like Ashford. People like him.
“Sorry, ese,” Bull said, and drove the joysticks forward.
Ashford’s forces were pulling back. There was no question about it now. Verbinski and his team were laying down a withering and professional spray of gunfire. The sniper, Juarez, didn’t fire often, but when he did it was always a kill shot. The combination of constant automatic weapons fire and the occasional but lethal bark of Juarez’s rifle kept moving the enemy back in toward the transfer point like they were boxing in the queen on a chessboard. Even the most powerful of Ashford’s guns couldn’t find a safe angle on them, and Verbinski kept the pressure on, pushing back and back and back until Ashford’s people broke, running.
The transfer point itself was a short hallway with emergency decompression doors at each end. As Bull watched, the vast red-painted circular hatches groaned and began rolling into place. They wouldn’t be enough to stop Bull and his people, but they’d slow things down. Maybe too much.
“Charge!” Bull shouted, then fell into a fit of coughing that was hard to stop. When he could, he croaked, “Come on, you bastards! Get in there before they lock us out!”
They launched through the air, guns blazing. The noise was deafening, and Bull could only imagine what it would sound like from farther away. Distant thunder in a land that had never known rain. He pushed his mech forward, magnetic boots clamping and releasing, as the doors rolled their way nearer to closed. He was the last one into the corridor. At the far end, the air was a cloud of smoke and blood. The farther door was almost closed, but at the side, Naomi Nagata was elbow deep in an access panel, Holden at her back with assault rifle in hand. As Bull approached, the woman pulled something free. A stream of black droplets geysered out into the empty space of the corridor, and the sharp smell of hydraulic fluid cut through the air. The door stopped closing.
In the chaos it was hard to say, but at a guess, Bull thought he still had between fifteen and twenty people standing. It wasn’t great, but it could have been worse. Once they got into engineering, things would open up again. There would be cover. The few meters beyond the second door, though, would be a kill zone. It was the space all his people had to go through to get anyplace else. If Ashford’s people had any tactical sense at all, they’d be there, waiting for the first sign of movement.
It was a standoff, and he was going to have to be the one to break it. Verbinski skimmed by, as comfortable weightless as a fish in water. He turned, tapped his feet against the wall, and came to something close to a dead stop.
“Going to be a bear making it through there,” the Martian said.
“I was just thinking that,” Bull said.
Verbinski looked at the half-closed door like a carpenter sizing up a board.
“Be nice if we had some explosives,” he said. “Something to clear the area a little. Give us some breathing room.”
“You trying to tell me something, Sergeant?”
Verbinski shrugged and took a thin black cassette out of his pocket. Bull hoisted his eyebrows.
“Concussion?” he said.
