蝦夷共和國
The Naval Battle of Miyako was a daring, but desperate attempt by the Republic of Ezo forces to neutralize the powerful "Kōtetsu". It was the first case of an "abordage" (boarding) maneuver on an ironclad steamship in Japan. Although the attempt ended in failure, the loss of the "Takao" was marginal. The Imperial Navy continued north unimpeded, and supported landing and combat operations of thousands of government troops in the Battle of Hakodate.
