”I do not know why.”
Nakaoka said so.
But，reason may have been present there.

Next day of he said so.
King of Tokugawa had arrived in Kyoto.
Of course，as commander in chief of Choshu Subjugation Army.
　
"End the mayhem by this."
This was intended to show the determination of Tokugawa.　
　
And therefore，Saigo maybe had to proceeding to the capital in a hurry.
Political move of Kyoto had been anticipated by the arrival of the king.　
　
Last time, Saigo was the chief of the General Staff.
Idea of destroy Choshu，Satsuma abandoned it already.
They wanted to avoid political blank of the presence of Satsuma.　

Of course they would had known the arrival to Kyoto of the king from the beginning.
Maybe they were also starting to kyoto accordingly.
(They might had not talk to Nakaoka about this as state secrets.)
 　
・・・・・・・・・　
　
Face.
　
"If visit the Choshu from us，seems to ask the alliance to Choshu from Satsuma.
First is very essential，we don't want subordinate to them."　
Simply it may have been just that.
Because this is like an idiot，but this feeling continues until the concluded of the alliance.　
　
"Saigo did not come to Choshu certainly.
But they want the alliance with Choshu certainly."
Nakaoka said so.
　
This 10 days ago，mastermind of the coup did harakiri at tosa he was a close friend of Sakamoto and master of Nakaoka.
That fact might have been reached to Choshu.
Many comrade were killed with him.　
　
Nakaoka and Sakamoto had continued to negotiate of alliance.
