The rider returned from the west on the fifth day.
His name was Odun. He was the senior man among the ten riders Batu had sent to settle the Kipchak dispute.
Mid-thirties, steady, not the kind of officer who exaggerated details to prove his worth. Batu had chosen him because reliable information was more important than dramatic reports.
Odun delivered his report standing, dust still clinging to his clothes from the ride.
"The Burjin clan submitted on the second day," he said. "Their elder accepted your judgement on the pasture boundary and paid the first tribute in horses. Twelve heads, good animals."
"And the Tergesh?"
"They refused. Their headman said the Jochid sons had no authority over pasture his grandfather's grandfather had grazed."
Odun stopped for a moment, weighing what came next.
"He said it in front of all ten of us. Then he had us escorted to the clan outskirts and instructed us not to return."
Batu studied him.
"No threats?"
"No." Odun frowned slightly. "Like he wanted to make his point without giving us grounds to escalate it into a conflict."
Careful, then. The headman understood the rules of escalation. Open hostility triggered military action. So he had chosen a form of resistance that lived in the narrow space between submission and rebellion.
Submit or fight created simple decisions.
Polite refusal was harder. Respond too softly and authority weakened. Respond too hard and you looked unreasonable.
"How many fighting men does the Tergesh clan field?" Batu asked.
"My estimate is around four hundred riders. Maybe a hundred and fifty with real combat experience."
"Mount quality?"
"Strong," Odun answered immediately. "Three good foaling seasons, their horse lines are healthy and well-fed."
Batu nodded once. Good information. Numbers, mobility, supplies.
"Get some rest. I want you available tomorrow morning."
Odun bowed his head and left.
Batu remained where he was, looking toward the felt wall of the tent. He thought about a clan headman who understood exactly how much resistance he could afford.
Technically, the man wasn't wrong.
Ten riders represented authority. They did not represent force.
The proper response to ten riders was a polite escort to the border. The message worked both ways. We acknowledge your claim. We reject it. And we are not foolish enough to hand you a reason for escalation.
Batu had used variations of that tactic himself in another life, when direct confrontation with entrenched systems had been impossible.
Smart move.
That meant the response needed to be smart too.
He sent for Khulgen and for Torghul, commander of the largest western tumen.
Ten thousand men on paper.
Closer to eight thousand once paper strength met reality.
Torghul arrived roughly twenty minutes after Khulgen.
Large man, late forties. The kind of commander who judged a room before speaking in it.
He watched Batu's expression, took measure of the mood, and sat without waiting for permission.
A sheet of felt lay across the table. Batu had scratched a rough charcoal map onto it.
The western Kipchak pasture lands and approximate Tergesh territory. A simple cross marking the center.
"Tell me how you'd handle the Tergesh situation," Batu asked.
Torghul studied the map before answering. "I would take two thousand riders west to surround the clan camp. Seize the headman's horses and cattle as a penalty levy and then leave fifty men behind to collect tribute for the next three seasons." He tapped near the marked territory. "If he resists, raze the outskirts and take his sons as hostages."
Competent answer, direct and effective.
"How long to mobilize two thousand riders and move west?" Batu asked.
"Four days to gather them from this camp. Three days to reach Tergesh territory. About a week."
"And while those two thousand riders are moving west, who watches the northern roads?"
Torghul paused.
"The remaining garrison."
"Reduced by two thousand men."
"Temporarily."
Batu didn't respond. He let silence do the work and watched Torghul look back at the map.
A few seconds passed.
Then Torghul stated, "The Ulus clan."
"They still hold a grievance over the bridge toll dispute."
Batu informed him. "Now assume the Tergesh headman sent a rider east. What do the northern roads look like when those two thousand men are stretched across the Ural steppe?"
Torghul leaned back.
Good. He wasn't defending the original plan. He was working through the new problem.
"I'm not criticizing your answer," Batu stated. "It answers the question I asked."
He touched the map lightly.
"But there's a larger problem beneath it."
He needed to know his actual strength before committing any part of it to a conflict.
For the next two hours, he did something he should have done during his first week in this body.
He reviewed the tumen structure with both men, methodically, the way a commander inspected an inherited force.
Roster numbers against effective strength.
Equipment condition.
Horse-to-rider ratios.
Supply distances between the main camp and forward positions.
Three tumens across the western territories.
Thirty thousand men on record.
By the end of the first hour Batu had enough information to reject the official number.
Twenty-two thousand effective.
Maybe twenty-four on a strong cycle, with adequate fodder and no disease moving through the horse lines.
Those were the numbers that mattered. Paper armies did not fight battles.
What he found matched his expectations more than he liked.
Strong cavalry.
Brave soldiers.
Experienced riders with high individual skill.
And almost no doctrine below the commander tier.
Scouting was improvised.
Riders were sent out the morning of a movement and reported back to whoever happened to hold seniority at the time. There was no standard reporting structure, no layered watch system to catch what one scout missed.
Signals between units were primitive.
One fire meant danger.
Two fires meant retreat.
Anything more complex traveled by mounted messenger, which meant delays in hours once operations became fluid.
There was no field staff officers.
Torghul personally made every major decision.
Which meant ten thousand men depended on one man's judgment continuing to hold.
Batu didn't state any of that outright.
He asked questions.
The answers built the picture on their own.
Torghul was intelligent enough to notice where the questioning was leading.
By the end of the second hour he had shifted forward, engaged now in a way he hadn't been at the beginning.
"The scouting system comes first," Batu said at last.
"Before we move one man toward the Tergesh problem, I want a three-layer screen. Lead scouts two days ahead. A middle screen one day ahead. A rear watch screen covering flanks and back trail. Every layer reports on a schedule to a single collection point."
Torghul considered it.
"We've never operated that way."
"I know." Batu nodded. "That's exactly why we're going to test it somewhere that isn't a war."
He tapped the mark showing Tergesh territory.
"Four hundred riders with no clear wish to fight makes a good training."
Torghul nodded slowly. He could see the value now.
"I'm riding with you," Batu informed him.
Both men looked at him.
"To see it from the field."
His eyes settled on Torghul.
"You keep command. What I learn out there will mold what we build afterward."
Torghul accepted that with a nod that carried more than formal obedience.
Batu recognized the expression.
A veteran officer who had done his duty well for years, then suddenly glimpsed a wider version of the work.
Not humiliation.
Interest.
For the right commander, greater complexity was exciting.
Torghul was that kind of commander.
Good.
"One more adjustment," Batu informed.
"The two-thousand-rider figure. Cut it to five hundred."
One of Torghul's eyebrows rose.
"Five hundred riders with in a good position and disciplined scouting will achieve the same result. The headman is cautious, not suicidal. A competent force that moves as if it knows exactly where his flanks are will persuade him faster than a larger force moving blind."
He let Torghul think through the logic.
It didn't take long.
"We move in three days," Batu continued. "Tomorrow is for scout selection. I want sharp and fast men, not necessarily experienced ones. Experience can be trained, but speed and instinct are harder to build."
He rolled up the felt map and set it aside.
Outside, the camp continued through its evening rhythms.
Firelight.
Horses.
The low, layered noise of thousands of men ending a day.
The Tergesh headman believed he understood the Jochid faction.
Ten riders sent away.
Then the expected response.
Mass. Speed. Overwhelming numbers applied with blunt certainty.
He had not considered a different possibility.
The man riding toward him had spent a lifetime learning how to make five hundred men accomplish the work of two thousand.
In three days, the headman would learn what that truly meant.
