Naval students were sent to study in Western naval schools for several years, starting a tradition of foreign-educated future leaders, such as Admiral Enomoto. The French naval engineer Léonce Verny was hired to build naval arsenals, such as Yokosuka and Nagasaki. By the end of the Tokugawa shogunate in 1868, the Japanese navy of the "shōgun" already possessed eight western-style steam warships around the flagship "Kaiyō Maru", which were used against pro-imperial forces during the Boshin War, under the command of Admiral Enomoto. A French Military Mission to Japan (1867) was established to help modernize the armies of the Bakufu. Japan sent a delegation to and participated in the 1867 World Fair in Paris.
