- Fighting at the various skirmishes in the 1860s, he most notably fought alongside Shinsengumi against Maki Izumi's force at Tennozan.
- Commanding Aizu artillery forces at the Battle of Toba–Fushimi, Gonsuke fought against overwhelming odds, coming under heavy fire while inadequately supported by spearmen instead of rifle infantry.
- Grabbing a long spear, he charged the enemy infantry but was shot repeatedly.
- Evacuated from the battlefield, he was placed on a Shogunate warship, and died at sea, en route to Edo.
- His age at death was 63. Gonsuke's ancestor Matazaburo was famous for having served under Torii Mototada and died at the Battle of Fushimi Castle.
