Thái Nguyên
One of the most effective uprisings during this period was in the northern Vietnamese province of Thái Nguyên. Some 300 Vietnamese soldiers revolted and released 200 political prisoners, whom, in addition to several hundred local people, they armed. The rebels held the town of Thái Nguyên for several days, hoping for help from Chinese nationalists. None arrived, however, and the French retook the town and hunted down most of the rebels.
