Enomoto Takeaki
Jules Brunet would become a leader of the military effort of the shogunate, reorganizing its defensive efforts and accompanying it to Hokkaido until the ultimate defeat. After the fall of Edo, Jules Brunet fled north with Enomoto Takeaki, the leader of the shogunate's navy, and helped set up the Ezo Republic, with Enomoto Takeaki as the President, Japan's only Republic ever. He also helped organize the defense of Hokkaidō in the Battle of Hakodate. Troops were structured under a hybrid Franco-Japanese leadership, with Otori Keisuke as Commander-in-chief, and Jules Brunet as second in command. Each of the four brigades were commanded by a French officer (Fortant, Marlin, Cazeneuve, Bouffier), with eight Japanese commanders as second in command of each half-brigade.
