Passage: With the start of the Boshin War, Hayashi Tadataka was at Jozai, and though he was not able to participate in the Battle of TobaFushimi, he set himself apart from all other fudai lords in that he invoked his hereditary obligation to the Tokugawa clan in going to war. Taking part in the guerrilla warfare efforts of Hitomi Katsutaro, Tadataka departed his domain with his entire retainer force, and fought from Izu Province all the way north to Aizu and Sendai as part of the Ouetsu Reppan Domei, finally surrendering when he received news that the main Tokugawa family had been given a fief at Sunpu (modern-day Shizuoka), in Suruga Province. However, in punishment for Tadataka's actions, Jozai was taken over by the new government. Tadataka himself was placed in confinement at the Edo residence of the Ogasawara family of Karatsu, of which his family was a branch line. He was later released, and held several government positions before his retirement, and was also made a baron (danshaku) in the kazoku peerage. Hayashi Tadataka was the last of the former daimyos to die, in 1941.
