Torghul was already at the starting area when Batu arrived.

He was standing at the horse’s near side. The boy was together, holding the lead.

He looked up when Batu came through the crowd.

"He’s ready," Torghul said.

He said it about the horse, not the boy.

The boy was Torghul’s youngest, nine years old, and he had been sitting on horses since he could be held on one. He sat on this horse with the ease of a child who did not think about sitting on horses, his body finding the position without consultation with his mind.

He was small even for nine, which was the reason he was here, and he looked at Batu across the animal’s neck with the forced composed face a child makes in occasions like this.

The horse itself was a grey, standing several hands at the withers with the lean frame that the Pontic steppe built in animals that had done nothing but run their whole lives.

The neck was long, the back was level and the quarters behind were deep and clean, not the thick muscled hindquarters of the mountain horse or the heavier eastern breeds but the long-muscled that created the stride rather than the push.

It stood at the starting area and breathed at the rate of a horse that was not yet interested.

"The coat came in late this year," Torghul said. "I thought we’d have a problem with it through the passes. We didn’t."

Batu nodded.

The crowd along the course awaited excitedly for what was next.

The news of which string was ready had moved through the watchers moved in waves, before the event itself could happen, so that every man along the course was already looking toward the starting area before the horse was brought to the line.

"They know what they’re waiting for," Torghul said.

"As they should," Batu said.

The boy made one adjustment to his position on the horse’s neck, settling his grip in the mane where it was thickest. He did not ask for direction and none was given.

Torghul stood back from the near side and the horse felt the absence and moved its head once and then was still again.

The starter’s call came from the course official at the line.

The boy lay forward and the horse went.

Not from a standing start into a sprint, that was not what the course was for, and a horse that burnt itself out in the first five hundred meters was a horse that had failed its test before it reached the midpoint.

The opening of the Naadam distance race was a steady acceleration. The animal feeling the release of the lead and finding its own pace, the ground confirming what the animal knew, and then the extension as the terrain flattened ahead and the course asked for what the breeding had built.

The crowd along the sides of the course strained their necks to watch as the horse passed the first watchers.

"That’s a western animal."

"Look at the back end."

"That’s not a Mongolian horse."

"No. Different country entirely."

Batu watched the animal go east.

The grey covered the first section of the course at a pace that could be seen as self-controlled, the pace of an animal that had been given a long distance and was finding the rate that would last it.

The crowd noise moved east with the horse, the line of watching men contributing their fragment as the animal passed each position, the collective sound of the course building and then diminishing as the grey opened the distance between itself and the starting area.

Torghul stood beside Batu and watched it go.

"The Ferghana horses," Torghul said. "The Chagataid string. Did you see them at the midpoint?"

"I was there."

"How did they look at the midpoint?"

"It was what expected," Batu said.

Torghul nodded once. That was his own interpretation confirmed, from a distance and through second-hand accounts.

"The Ferghana horse is built for the burst and the sprint. When you give it a long flat course it looks magnificent for the first half. The second half tells you what the breeding actually is limited by."

He kept his eyes east on the diminishing shape of the grey.

"This one won’t fade that way," he said.

The crowd noise along the course had shifted further east.

Somewhere at the midpoint, specific voices were carrying back to the starting area in interest and recognition. Batu could not hear the words. The volume of the noise was enough.

A man standing three paces to his left at the grounds said something to the man beside him and the man beside him laughed, and then the man beyond him leaned over to ask what had been said.

"What do they look like at the turn?" the first man called out to someone further up the line who had a better angle.

"Like they’re only half spent," the answer came back.

"Half spent at the turn means-"

"I know what it means."

Torghul said, "My son has a good hand. He’s not fighting the animal."

"He’s not moving either."

"No. He’s learned not to move."

He turned his cup in his hands. He had brought one from somewhere, the cup had appeared without Batu noticing.

"The first time I put him on a distance horse he moved the whole race. We lost half the distance in unnecessary motion. I showed him once what the difference looked like from the ground. He hasn’t moved since."

The sound changed at the course’s midpoint.

The noise that had been moving east with the animal turned and started moving west.

The horse had rounded the far marker and was on the return leg, and the crowd along the course was receiving it again in the order the distance required.

The far watchers first, the sound of them carrying back, then the closer ones, and then the visual of the animal itself appearing at the end of Batu’s sight range from the starting area.

The grey came back at a pace that was not the same as the pace it had left at.

It was faster.

The speed of a horse that knew itself and was now closing on with reserve still available.

The hindquarters were driving with the same evenness they had shown in the first moments at the starting area, no twist in the coupling, nor compensating motion in the back.

The boy on its neck had not changed his position.

"There it is," Torghul said.

The crowd in the midpoint shouted with far more interest than the the prior groups.

"It’s still running."

"It ran this far and it’s still running."

"At the turn it had more in it-"

"I told you."

"I heard you. I didn’t believe you."

"That’s a western steppe horse. That’s what they are."

The grey came through the final section of the course at the pace had been building toward since the starting line, the boy flat on the neck, and then the grounds at the starting area was full of people catching up to what had just passed through them.

The demonstration of what the animal was and where it came from and what an army built on those animals could do.

Torghul stepped forward when the horse came to rest and put his hand on the animal’s neck at the shoulder and left it there, feeling what the distance had cost the animal and what it had kept.

He stood with his hand in that position for a few seconds.

"Good," he said.

To the horse, or to no one in particular, which was how Torghul often made his most accurate remarks.

The boy slid down from the horse’s back and stood with the lead in his hands and looked at his father.

Torghul looked at him.

"Your hands were steady."

"You told me to keep them steady."

"I tell you a lot of things."

"I kept my hands steady," the boy said.

Torghul said nothing.

He turned back to the horse and ran his hand along the flank and checked what the animal’s breathing told him.

He stood there watching it for a moment.

Batu turned and walked back through the crowd that had gathered at the course, the camp visible beyond it and the Orkhon beyond the camp and the mountains at the valley’s far edge against a sky that was carrying the afternoon’s first real heat.

The last piece of the games period was behind him.

He walked and did not think about what the grey had just demonstrated. Those who had to think about it were the other princes and their factions.

For him, the next problem was ahead.
