Background and detail

Background. In early spring 1868, former Tokugawa retainers left Edo and gathered at Kōnodai. As these troops retreated north towards Nikkō and Aizu, they moved quickly from castle to castle. Hijikata Toshizō took domains in Hitachi Province on May 7 and 8, setting the stage for the engagement at Utsunomiya Castle.

Engagement. A peasant riot in Utsunomiya provided an opportunity for former Shogunate forces. Ōtori Keisuke launched an attack on May 10, facing a combined imperial force from various domains. The imperial army later swept northeastward on May 14, launching a counterattack that resulted in the recapture of Utsunomiya Castle.

Aftermath. Ōtori's men linked up with Hijikata's force, including Seiheitai, and headed north to Mibu. However, they discovered Satsuma forces had already taken the castle. The entrance of massive numbers of loyalists following their retreat from Utsunomiya forced the Aizu domain into armed resistance.
