松平容保
After a month under siege, in November 6, 1868, Aizu officials agreed to surrender, through the mediation of their neighbor, the Yonezawa Domain. Soon after, Matsudaira Katamori, his son Nobunori, and the senior retainers came before the imperial commanders in person, and offered their unconditional surrender. The samurai population was sent away to prisoner of war camps in the Tsugaru Peninsula, and the Aizu domain, as it had been since the mid-17th century, ceased to exist.
