Battle of Aizu
Hoshina's descendants would rule the Aizu Domain for the next 200 years, adopting the Matsudaira name until the ninth generation Daimyō, Matsudaira Katamori, backed the bakufu in the Boshin War. Aizuwakamatsu Castle would fall during the Battle of Aizu and the domain forfeit. 22 loyal retainers and their families managed to escape to California and lend the name of their home to establish the first Japanese colony in America, the ill fated Wakamatsu Tea and Silk Farm Colony in 1869.
