 In 1867, the first French Military Mission to Japan arrived in Yokohama, among them Captain Jules Brunet.The military mission would engage into a training program to modernize the armies of the shogunate, until the Boshin war broke out a year later leading to a full-scale civil war between the shogunate and the pro-Imperial forces.By the end of 1867, the French mission had trained a total of 10,000 men, voluntaries and recruits, organized into seven infantry regiments, one cavalry battalion, and four artillery battalions.
