Kōga Gengo
Gengo endured the inferiority and was fiercely commanding on the deck while being shot through the left foot and right arm by bullets, but as he charged at the sailors, he was shot through the head by a rifle bullet. He was 31 years old.  The ship was taken command by Arai and retreated back to Hakodate on the 26th, and Gengo;s body was buried the next day. The place of his burial was a certain temple, but it is said that it was later reburied behind the Hekketsu-hi Monument. In 1931, his nephew and adopted child, Nobumasa Kōga, built a monument in the precincts of the Daikannon Light Source Temple in Komagome, Tokyo, near the former Kakegawa clan's residence.
