The floor remained open and the minor princes began to speak.

Chaga son of Toquchar rose first from the Ogedeid section’s inner ring. He was perhaps thirty, well-dressed in the way of who understood that presentation in formal was its own argument, and he addressed the session floor with the ease of who had been preparing this for longer than the three days of the games period.

"The empire has conducted every campaign of consequence under command that answers to the ancestral land," he said. "From the first campaigns of the Great Ancestor to the reduction of the Jin territories, the army answers to the Great Khan and to the commanders the Great Khan designates."

He let that be clear, and then continued, "The western campaign is not a local operation. It crosses a distance that makes it the largest undertaking this assembly has ever authorized. A campaign of that scale requires the clearest possible line of authority. The Ogedeid line stands for that principle."

He sat.

Yeke Noyan’s younger son rose from the eastern side of the same cluster. He was younger than Chaga and held himself differently, the forward lean of someone with something specific he wanted to say.

"The Ogedeid line has built the eastern campaign structures," he said. "The relay networks, the supply depots, the systems that sustained the Jin campaign across four seasons. That knowledge belongs with the command authority for the next effort."

He sat.

Two more voices from the Ogedeid fringe contributed brief endorsements of the principle, neither adding argument, both adding numbers. The session registrar acknowledged each declaration as it came and the accumulated record of the morning was visible to everyone present in the running count of who had said what.

Batu read the Ogedeid cluster’s faces as each speaker finished.

The arguments were technically correct in their own way. Unified command had run every major campaign. The Ogedeid experience was real. Neither point was wrong.

What they both avoided was the question he had put to Chagatai and Chagatai had not answered, name the man who could command the western campaign from a different base and still win it.

An unnamed prince from the northern territories spoke next, positioning himself with a brief statement of support for the administrative competence argument. Then another, from the Kipchak fringe, who spoke to the supply line’s importance and left the conclusion for the assembly to draw.

Batu tracked the declarations without expression.

Nachugu had not risen. Koden had not risen. Both men sat in their respective positions, present and without the urge to be one of the first to speak.

Their silence was not nothing. Every man on the session floor could read a man who chose not to speak the same way they could read a man who did, and what Nachugu and Koden’s silence said was different from what Chaga’s voice had said, and different from each other.

Then the floor moved the other direction.

A voice from the western outer ring, a minor prince who had ridden the southern routes and knew the Jochid tribute network through the Ayas caravanserai contracts, stated that the administrative infrastructure already in place represented a campaign asset the empire could not afford to discard.

He was specific and named the Bukhara paper contracts and the relay network by function without naming any authority behind them. The assembly received it as what it was.

Two more voices followed the same line, each one shorter than the last, the accumulation doing the work that individual argument couldn’t do as efficiently.

Batu looked at Arghun’s position. Arghun had not moved. His camp’s riders were behind him in the precise configuration of men waiting for a signal from their lord.

Arghun was watching the session floor in an attentive, unreadable way.

Then Mongke rose from the Toluid section.

The session floor recognized the shift in speaker in the difference between minor voices and a senior Chinggisid line. The sound of the assembly settling down a different volume of attention, slightly below the surface of the open-air noise, a collective reorientation that was felt before it was seen.

Mongke stood with his hands at his sides and looked at the floor for a moment before he spoke.

"This assembly has heard two arguments this morning," he said. "One argument names the principle of unified command and asks this floor to endorse it."

He let the silence do its work before continuing, "The other names the reality of a campaign that must sustain itself months from its nearest base and asks this floor to recognize what that requirement actually demands."

He paused.

"The principle of unified command is valid. Every campaign the empire has run succeeded in part because the command structure was clear."

The words brought the entire attention from the floor, "The question is not whether to maintain unified command. The question is whether the man designated as campaign authority has the infrastructure already in place to exercise it, or whether he will spend the campaign’s first season building what should have been there before the advance began."

He looked toward the Chagataid section briefly and then back at the full floor.

"The reason is that a khanate which has already proven its capacity is suspect because of who built it, rather than what it can do. This assembly should name that reason for what it is and set it to the side."

Several men in the minor princes’ outer ring moved in their positions in a way that was not quite standing but was not quite sitting either, the particular motion of people receiving something that required a response they were not ready to make aloud.

"Batu Khan has built the khanate that the western campaign requires," Mongke said. "The supply relay from the Volga, the survey of the river crossing networks, the tributary system that has the supply routes. This assembly is choosing which outcome it will create."

He sat.

The session floor caught what he had put into it for a few seconds without filling it with new sound. Then the smaller noise of the assembly reconstituting itself after something had landed came back in from the crowd.

Batu observed the faces across the arc from his position.

Two of the minor princes who had delivered brief endorsements of the unified command principle were looking at the floor in front of them rather than at each other.

Chaga’s posture had gone slightly more forward than it had been before Mongke spoke.

Koden’s position had not changed in any visible way. Arghun was still watching.

Then Guyuk rose from the Ogedeid section.

He came to standing with ease, of who had been deciding when to speak for the last several minutes and had reached his answer.

He looked across the session floor, the Jochid section on the left, the Toluid section beyond it, the minor princes in their arc, the declarations that the morning had accumulated from both directions.

Batu caught it.

The picture Guyuk had been working from had a western tumen weakened and strained, a campaign authority struggling through winter, a Jochid position that the Ogedeid faction could define on its own terms before the assembly convened.

That picture was eighteen months old and calibrated. What the morning had told was something different in its place, and Guyuk, standing with the session floor in front of him and the declarations of the morning behind him, had just finished accepting the reality.

He composed himself and looked toward the Great Khan’s direction and began to speak.
