Luke pointed at him. “Don’t say it. Just get ready to fight.”

“I’m always ready to fight,” Martinez said.

The shooting started moments later.

* * *

Martinez was screaming.

“They’re coming through on all sides!”

His eyes were wide. His guns were gone. He had taken an AK-47 from a Taliban, and was bayoneting everyone who came over the wall. Luke watched him in horror. Martinez was an island, a small boat in a sea of Taliban fighters.

And he was going under. Then he was gone, under a pile.

They were just trying to live until daybreak, but the sun refused to rise. The ammunition had run out. It was cold, and Luke’s shirt was off. He had ripped it off in the heat of combat.

Turbaned, bearded Taliban fighters poured over the walls of the outpost. Men screamed all around him.

A man came over the wall with a metal hatchet.

Luke shot him in the face. The man lay dead against the sandbags. Now Luke had the hatchet. He waded into the fighters surrounding Martinez, swinging wildly. Blood spattered. He chopped at them, sliced them.

Martinez reappeared, back on his feet, stabbing with the bayonet.

Luke buried the hatchet in a man’s skull. It was deep. He couldn’t pull it out. Even with the adrenaline raging through his system, he didn’t have the strength left. He looked at Martinez.

“You okay?”

Martinez shrugged. He gestured at the bodies all around them. “I been better than this before. I’ll tell you that.”

There was an AK-47 at Luke’s feet. He picked it up and checked the magazine. Empty. Luke tossed it away and pulled his handgun. He fired down the trench—it was overrun with enemies. A line of them were running this way. More came sliding, falling, jumping over the wall.

Where were his guys? Was anyone else still alive?

He killed the closest man with a shot to the face. The head exploded like a cherry tomato. He grabbed the man by his tunic and held him up as a shield. The headless man was light—it was if the corpse was an empty suit of clothes.

He killed four men with four shots. He kept firing.

Then he was out of bullets. Again.

A Taliban charged with an AK-47, bayonet attached. Luke pushed the corpse at him, then threw his gun like a tomahawk. It bounced off the man’s head, distracting him for a second. Luke used that time. He stepped into the attack, sliding along the edge of the bayonet. He plunged two fingers deep into the man’s eyes, and pulled.

The man screamed. His hands went to his face. Now Luke had the AK. He bayoneted his enemy in the chest, two, three, four times. He pushed it in deep.

The man breathed his last right into Luke’s face.
