The official chronicle of Emperor Kōmei (Kōmei Tennō-ki, published 1906 by Imperial Household Ministry), volume 187, opens with the attack on outlaws in Kyoto by Bakufu security forces on the fifth day of the Sixth Month of the Japanese calendrical year that corresponds to 1864. The obvious is not stated in the heading: i.e., no mention of the names Shinsengumi or Ikedaya.
