Batu spent the morning doing exactly what the camp expected from him.
He inspected the horse lines. He listened to his quartermaster's supply report and noted nothing immediately wrong with it. He ate with two senior officers and contributed almost nothing to the conversation.
By midday the camp returned to the predictable rhythm of an ordinary day. Calm made people careless.
Khulgen found him near the eastern paddock.
"The rider Temur described," Batu noted, still checking the horse's legs. "Has he moved?"
"Not yet. He's still in the supply train. Calls himself Arslan while pretending to be a grain merchant's assistant."
"How long has he been there?"
"Eleven days."
Long enough to learn about the camp. Maybe long enough to pass information back out.
Batu returned the horse's lead to the groom.
"What's the supply train schedule?"
"It will leave in three days."
"Then he intends to leave with it."
He started toward the paddock fence, thinking through the timing. "I want him watched. Every man he talks to, every tent he enters, every time he steps away to piss. I want every contact identified."
Khulgen nodded.
"Don't use anyone from the normal guard. Use someone he's never seen near my tent."
"I have a man. Jebe's younger brother. He's sharp and outsiders don't know him."
"Agreed."
Batu looked out across the paddock. The horses moved in slow circles, heavy with rest and good feed.
He had strong horses. Reliable mounts were extremely important in the steppes.
"There is another problem," he noted.
Khulgen waited.
"About the night watch schedule, my tent layout, the vulnerability in the third rotation. A grain merchant's assistant doesn't get to know that by wandering around camp."
Khulgen's expression shifted as he worked through the implication.
"Someone inside the senior council gave it to him."
"And that man is still attending my morning meetings."
The paddock fence creaked as wind pressed against it. Beyond the fence, grass flattened, then recovered.
"How many men have access to the watch rotation schedule?" Batu asked.
"Under the current structure, eight. The watch commander. His two deputies. Five senior council members who receive the nightly security summary."
"Five council members," Batu said. "Small enough."
Khulgen studied him. "Then?"
"I'm going to give each of those five men a different piece of information today, enough to seem ordinary. One of them false in a specific way."
He paused, checking the thought one more time.
"When that false information starts moving, I'll know which direction it traveled from."
Khulgen went stiff for a heartbeat. "And if more than one of them is sending information east?"
"Then I gain two names instead of one."
Batu turned from the fence.
"But I don't think this comes from more than one man."
He walked back toward the center of camp. "I want the five names and their current assignments on my table before the afternoon meeting."
"It will be done."
"And."
He did not slow. "The new night watch. Every third guard in the overnight cycle goes to men who've served with me more than two years. No exceptions."
"Understood."
Khulgen peeled away toward the command tents. Batu continued toward the main camp, already sorting through priorities.
The afternoon meeting dealt with routine matters.
Fodder projections for the coming month. Bridge conditions along the western supply road.
Two minor tributaries complained about grazing rights on the northern pasture. Batu ended the dispute in under half a minute by drawing a line through the contested ground and declaring the eastern half a military fodder reserve. Neither man could protest without sounding opposed to army readiness.
He watched the five council members the entire time.
Where their eyes shifted when certain subjects surfaced. Which topics made them lean forward. Which made them hold unnaturally still.
Nothing conclusive.
But one man, a senior logistics officer named Borte-Qol, repeatedly glanced toward the tent entrance whenever supply movement came under discussion.
After the meeting Batu summoned the five men individually, spaced through the late afternoon and hidden beneath different excuses.
To each he delivered a small piece of information almost casually. A side note buried inside a larger conversation. Exactly the kind of thing a man might repeat to a contact because it seemed harmless.
To the first, he mentioned that the eastern scouting patrol had been delayed two days because the lead unit had a lame horse.
To the second, he mentioned a shipment of salted meat due from the northern camps on the fourth day of next week.
To the third, he mentioned that Temur, the merchant's runner currently in custody, had been released that morning after proving useless.
That version carried the sharpest danger.
If it moved, it would move quickly. Whoever heard it would assume Temur was loose and vulnerable. A free witness could be silenced.
The urgency would change behavior. That was the point.
To the fourth and fifth he gave two additional variants of Temur's hint. Both harmless enough if repeated. Both distinct enough to trace.
He did not tell Khulgen which man had received which version. He told no one.
That evening Batu sat alone inside the repaired tent and reviewed the watch commander's notes from the previous month.
He was putting together a picture of the camp itself. Which information traveled fast, which stalled. Who habitually spoke to whom.
Which officers maintained friendships that crossed formal boundaries.
He had spent twenty years in another life building mental pictures like these.
Organizations changed. Men did not.
Every structure developed weight, in a way information flowed downward toward the people who required it and sideways toward the people who simply wanted it.
The difference between those two was where weaknesses lived.
His camp was competently run. Competent was acceptable as a baseline.
But a baseline was not enough.
And someone had just cut a hole through it.
He marked three changes for the watch command, changes he would implement only after identifying the leak, because altering anything now would warn anyone observant enough to matter.
He folded the notes and set them aside.
A rider had arrived from the west that afternoon.
A trade dispute between two Kipchak clan leaders over winter pasture on the Ural steppe, presumably a small matter.
Both clans answered, at least nominally, to Jochid authority. Both were testing whether that authority actually carried weight.
In the old history, Batu's focus during this period had been eastward on court politics.
The western steppe had been handled loosely. Later, that neglect had required a full military campaign to break the Kipchaks.
He did not intend to repeat that mistake.
He pulled a piece of felt closer and scratched out a short instruction.
The dispute would be judged.
A Jochid officer would ride west within the week carrying Batu's ruling and the authority to enforce it.
Ten men would be enough. The goal was was presence.
The western steppe needed to understand that the hand holding the reins had changed.
He set the felt aside and watched the lamp flame.
Arslan remained inside the supply camp.
One of five council members was carrying false information and did not know it yet.
And somewhere to the west, two Kipchak leaders were about to discover that Jochid authority now answered quickly.
Small moves.
But the board had grown larger since last week.
He blew out the lamp and lowered himself onto the sleeping mat. It had a new cover now. The old one had been cut apart for bandages the previous night.
His ribs still hurt.
He slept anyway.
