The French installed a post at Tuyên Quang in June 1884, in the wake of their capture of Hưng Hóa and Thái Nguyên. Tuyên Quang, an isolated settlement on the Clear River, was the most westerly French outpost in Tonkin, and was more than 100 kilometres away from the French garrisons in Hưng Hóa and Thái Nguyên. During the summer and autumn of 1884 the post was garrisoned by two companies of the 1st Battalion, 1st Foreign Legion Regiment (Captains Chmitelin and Broussier), under the command of "chef de bataillon" Frauger.
