The French military mission of 1867-1868 was one of the first foreign military training missions to Japan, and the first sent by France. It was formed by emperor Napoléon III following a request from the Tokugawa shogunate through its emissary to Europe, Shibata Takenaka, with the goal of modernizing the Japanese military.
Shibata was already negotiating the final details of the French support for the construction of the Yokosuka Shipyard, and had additionally requested both the United Kingdom and France to send a military mission for training in Western warfare. The United Kingdom provided support to the Bakufu naval forces through the Tracey Mission. The French foreign minister Drouyn de Lhuys transmitted the agreement of the French government to provide training to the Shōgun's land based armed forces.
The mission left Marseille on November 19, 1866, and arrived in Yokohama on January 14, 1867. They were welcomed on their arrival by Léon Roches and the commander of the French Far East Squadron Admiral Pierre-Gustave Roze.
The military mission was able to train an elite corps of shōgun Tokugawa Yoshinobu, the Denshūtai, for a little more than one year, before the Tokugawa shogunate lost to the Imperial forces in 1868 in the Boshin War. The French military mission was then ordered to leave Japan by decree of the newly installed Meiji Emperor in October 1868.
In contravention of the agreement for all foreign powers to remain neutral in the conflict, Jules Brunet and four of his non-commissioned officers (Fortant, Marlin, Cazeneuve, Bouffier), chose to remain in Japan and continue supporting the Bakufu side. They resigned from the French army, and left for the north of Japan with the remains of the Shogunate's armies in the hope of staging a counter-attack.
The conflict continued until the rebels' defeat at the Battle of Hakodate in May 1869.
The mission consisted of 17 members, under the authority of the Minister of War General Jacques Louis Randon, covering a wide range of expertise: four officers (representing infantry, artillery and cavalry), ten non-commissioned officers and two soldiers. The original mission composed of 15 members, arriving in Japan in January 1867, and was later supplemented with non-commissioned officers Cazeneuve, Jourdan and Michel (February 1868). The mission was headed by staff captain Charles Sulpice Jules Chanoine, at that time an attaché to the military staff of Paris. The members were:
- Charles Chanoine, captain of the general staff
