and Shimodate—on May 7 and May 8. However, as these domains were small and their daimyō had fled, they did not have much in terms of money or supplies, and Hijikata was unable to acquire what he had hoped for. Almost simultaneously, a peasant riot broke out in Utsunomiya, giving the former Shogunate forces the perfect opportunity to strike, which they seized without delay. Ōtori's forces launched their attack on the castle on the morning of May 10, 1868, facing off against the combined Imperial force made up of troops from

's unit Seiheitai, headed north to Mibu, where they intended to hide and lie in wait; however, upon their arrival they discovered that Satsuma forces had already taken the castle. The southerners, shocked at their sudden appearance, entered the castle and mounted a defense; and while the attackers had intended to set fire to the castle town, a torrential rain began, and made that impossible. Despite their best efforts, this combined unit was not able to take Mibu Castle, and withdrew to Utsunomiya after sustaining a total of 60 men killed and wounded, including eight officers. Subsequently, the Imperial army, with Satsuma and Ōgaki forces leading the way, swept up in a northeastward direction over the Mibu-kaidō road on May 14, launching a counterattack which resulted in their taking of the castle on the same day.
Faced with defeat, Ōtori's forces withdrew northward, by way of Nikkō, on to Aizu.
Aftermath
It is important to note that while the Aizu domain previously advocated surrender and peaceful negotiation first and resistance second, the entrance of massive number of loyalists to the former Shogunate, following their retreat from Utsunomiya, forced its hand firmly into the realm of armed resistance:
"...soldiers of the Shogunate, who supported continued war, began decamping en masse and leaving Edo for Aizu, which necessitated Aizu's stance to be changed to one that was pro-war. Men such as senior councilor Saigō Tanomo and agriculture magistrate Kawahara Zenzaemon continued to push for allegiance and submission, however, they were not heard, and the clouds of war spread over northeastern Japan..."
In later years, Ōtori would write an account of the battle, titled
Nanka Kikō (南柯紀行), which would appear in
Kyū Bakufu (舊幕府), a magazine devoted to documenting Bakumatsu history, which he helped edit.
