The water was cold. That was the first thing he noticed. Then the bullets. Then he was moving, or someone was pushing him, and the sand was in his mouth and his knees were bleeding and he thought, this is a shit way to die, and then he didn't think anything at all because the world had gone too loud.

Sergeant Tommy Brennan hit the water of Omaha Beach running. He was five-foot-eight and two hundred and thirty pounds and his knees had been bad since a lifting accident in 2038, and now he was running through chest-deep water under machine gun fire in Normandy in the year 1944, and his body was doing things it had not done in six years.

He reached the beach. He fell. He crawled. The sand was wet and cold and full of things he did not want to identify. Danny O'Brien was to his left, a young Irish kid who looked twelve and was probably nineteen, holding his rifle like it was going to bite him.

"Don't stand up," Tommy said. His voice was calm. It was always calm now. "Don't stand up. Stay low. Move when you see the smoke clear."

"Move where?" Danny asked. His hands were shaking so hard the rifle was rattling against his chest plate.

"Left. When the smoke clears, you move left. There's a depression about thirty yards out. It'll give you some cover."

"How do you know that?"

Tommy looked at him. The kid's eyes were wide and white in a face that was all dirt and sweat and terror. Tommy thought about telling him that he knew because he had studied the footage. He had seen this beach a hundred times on documentaries and reenactments and tactical analyses. He knew where the German positions were because he had read the after-action reports. He knew which patches of sand would kill you and which ones would let you live.

But you don't tell a nineteen-year-old kid that you've seen his death in a video. You don't tell him that you know exactly which shell will hit the emplacements ten minutes from now and which one will land three feet to the left and spray shrapnel across a section of beach that will be empty for exactly forty-seven seconds.

"I just know," Tommy said. "Trust me."

He didn't deserve trust. He was a fat ex-sergeant from Birmingham who had spent fifteen years in the Royal Engineers and another ten drinking himself into a slow decline and waking up on this beach with no idea how he'd gotten there. But Danny trusted him. Danny trusted everyone, really—the world was a big place and it was full of people who might help you if you asked nicely.

The smoke cleared. Tommy moved left. He pulled Danny with him by the back of his uniform. A bullet hit the sand where Danny had been sitting three seconds before. Danny did not notice. He was too busy breathing.

They reached the depression. It was a shell crater, maybe four feet deep, filled with seawater and debris. Tommy sat down in it. Danny sat down beside him. They were both breathing hard. Neither of them had been shot. Yet.

"Are we going to die here?" Danny asked.

Tommy looked at the beach. People were running and falling and running again. Some made it to the bluffs. Most didn't. The German machine guns were positioned on the cliff top, firing in a pattern that Tommy recognised from the tactical analyses—heavy, methodical, efficient. They weren't wasting ammunition. They were waiting for the Americans to present targets.

"No," Tommy said. "We're not going to die here."

It wasn't a promise. It was a calculation. He had calculated, in the first thirty seconds of hitting the beach, that the probability of any individual soldier surviving this landing was approximately forty percent. He had then calculated, using knowledge of German troop deployments and artillery schedules that would not be fully declassified for another seventy years, that Danny O'Brien's probability of survival was approximately sixty-five percent if he followed Tommy's instructions exactly.

Danny didn't need to know the numbers. He needed to know that someone smarter and more experienced was telling him where to move. That was enough. It had to be enough.

The morning passed. Tommy moved men through the beach the way a conductor moves notes—small adjustments, precise timing, nothing dramatic, nothing heroic. He told Hayes, the lieutenant, to stop standing in the open and get behind the landing craft hull. He told O'Malley to stop trying to be brave and start being useful. He told Marsh, the medic, to set up her station behind the second dune where the casualties would actually arrive instead of waiting on the beach where they would arrive dead.

He took two bullets himself. One in the left thigh. One in the abdomen, low, through the fat that was supposed to be his greatest liability and turned out to be, for exactly twenty minutes, his greatest asset. The bullet had been meant for his intestine. It had hit the layer of adipose tissue first and lost enough energy to stop just short of penetration. It hurt like hell. But it didn't kill him.

Danny didn't take a bullet. O'Brien didn't take a bullet. Hayes didn't take a bullet. Marsh didn't take a bullet.

Six men in Tommy's section took bullets instead.

By three in the afternoon, they had reached the bluff. Tommy climbed the last twenty feet on his elbows and knees, leaving a trail of blood and sand and things he refused to think about. He reached the top. He lay on the grass and stared at the sky and tried to remember what the sky looked like in Birmingham on a Sunday morning in summer.

He couldn't remember.

Danny sat down beside him. He was shaking. Not from fear now. From the aftermath. His face was grey. His hands wouldn't stop moving.

"I killed someone," he said.

"Yeah," Tommy said.

"How do you—"

"You don't. You just do it. And then you keep doing things. That's all there is."

Danny was quiet for a long time. Then: "Was it worth it? Coming here?"

Tommy thought about Margaret. He thought about their house in Erdington, the small garden with the rose bushes she had planted five years ago and never got to see bloom because he'd been too drunk to water them. He thought about the letter he'd received three months before the accident—Margaret's sister writing to say that Margaret had left, taken the cat, gone back to her mother in Wolverhampton. He thought about the fact that he had woken up in 1944 and the first thing he had felt was not confusion or wonder or awe but relief. Relief that he was somewhere else, somewhere where nobody knew his name, somewhere where he could be someone other than the man who had failed at everything for forty years.

"Yeah," he said. "I suppose it was."

It wasn't the truth. But it was close enough.

He survived the war. He survived the peace. He went back to Birmingham, which had not waited for his return to carry on without him—the factories were still running, the rain was still falling, the people were still living their lives in houses that looked the same and smelled the same and sounded the same.

Margaret didn't come back. Her sister didn't want him around. The city didn't care.

He kept his discharge papers in a drawer. He kept the medal they gave him in a box. He kept the memories of Danny O'Brien and the other five men who had died in his section on Omaha Beach in the back of his mind, where he could access them when he needed to remember why he couldn't sleep.

He died in 2061, at the age of eighty-one, in a hospital in Birmingham, surrounded by people who knew him as a quiet, somewhat sad man who never married and never had children and who used to sit in the park every Sunday and watch the pigeons and smile in a way that suggested he was seeing something they couldn't see.

He was seeing the beach. He was seeing the water. He was seeing Danny, nineteen years old, shaking, holding a rifle like it was going to bite him, trusting a fat sergeant from Birmingham to tell him where to move.

He was seeing the future he had tried to change and failed to change and changed in ways he would never understand.

And he was thinking, as he had thought on the beach and in the hospital and in every moment in between: this is not how it was supposed to go.

But it was how it went.
