蝦夷共和國
On the fourth week of May 1869, Hijikata led 230 Republic of Ezo forces and the surviving Shinsengumi against the 600 strong Imperial forces during the Battle of Futamata for sixteen hours and were forced to retreat. The Imperial forces attacked again on the next day, only to retreat. On the following night, Hijikata led a successful raid on the Imperial forces' camp, forcing them to flee. Hijikata and his forces would later retreat to Hakodate on June 10.
