徳川家達
During the Bakumatsu period, the Tokugawa shogunate belatedly attempted to modernize its military forces with the assistance of French military advisors. The attempt was ultimately unsuccessful, and following the Boshin War of the Meiji restoration, the Tokugawa clan, formerly masters of the country with revenues of over eight million "koku," were reduced to 700,000 "koku", spread across the provinces of Suruga, Tōtōmi and Mikawa, with the head of the clan, Tokugawa Iesato, moving to reside at Numazu. At this time, a group of "hatamoto," led by Ebara Soroku, Abe Kuninosuke and Yatabori Keizō returned from studies in the Netherlands, and decided to establish a military academy along western lines within the grounds of Numazu Castle in December 1868.
