In 1864 July 8th, Ikedaya case happened. Shinsengumi beat Sonno Joi ha (supporters of the doctrine of restoring the emperor and expelling the barbarians). When he heard that Isami Kondo’s army had found Sonno Joi ha, he immediately joined forces. But he didn’t storm Ikedaya immediately and ambushed around there. The achievements of the Shinsengumi in the Ikedaya case were very great. So the prize was exceptional.
