Sanjo Seisatsu Incident
On 1866/8/28, the seisatsu was pulled down and trashed on the side of Kamo River. On 9/2, the seisatsu was replaced, however it was gone again in three days.
The Shinsengumi sent 34 members in three groups:
At midnight of 9/12, eight Tosa han samurai showed up and pulled the seisatsu down. Arai's unit and Harada's unit killed or captured three of them, but they missed five others.
Ôishi's unit was late because Asano, who was supposed to let them know if anyone showed up, was scared of the Chôshû samurai and took the long way to the place where Ôishi's unit was located.
