why

katsura arrived to Kyoto and they went into the discussion of the alliance.
After a while，Sakamoto also came to Kyoto.
　
By the way，you may seem Sakamoto came to kyoto easily.　
But after this he was almost caught by Tokugawa.　
Maybe he was being monitored from the beginning.
Their actions were risk of life always.　
(Katsura had a strict guard of Satsuma at this time.)　
　
When Sakamoto visited Katsura in Satsuma mansion，he was about to just go back to Choshu.

”What was the content of the alliance?”
Sakamoto asked.

”We did not have until the end any discussion about the alliance."
"What?"

"We did not have any discussion until the end.
I came to Kyoto from me for meet to Satsuma.
Certainly they gave me welcome.
But they did not have any suggestion from them about the alliance until the end.
Nothing.
　
First，Choshu came to kyoto.　
I think should speak from Satsuma.
Otherwise there is no face of Choshu.
I had better go back to choshu than still here.”
　
”Do you still have said such a thing.”
Sakamoto said angrily.
　
"We made an effort certainly for the alliance between the two countries.
But it's not for the two countries.
It's only for the future of Japan.

We believe Satsuma-Choshu Alliance is required surely to Japan.
Nevertheless，the two countries has been only care about their own pride.
　
Why you guys do think only of own country?
Why you guys do not think the future of Japan?”
