Tôn Thất
On 4 July 1885, a nationwide insurrection against the French broke out under the leadership of the two regents Nguyễn Văn Tường and Tôn Thất Thuyết. The French stormed the palace and Tôn Thất Thuyết took Emperor Hàm Nghi and three empresses into hiding. Hàm Nghi went to the hills and jungles around Laos along with Tôn Thất Thuyết's force. While they waged guerrilla warfare against the French occupation forces, the French replaced Hàm Nghi with his brother, Đồng Khánh, who was enthroned as the Son of Heaven. In October 1888, after a series of setbacks, Hàm Nghi was hiding in an isolated house near the spring of the Nai river, with Tôn Thất Thiệp, the second son of Tôn Thất Thuyết, and only a few attendants. There, he was betrayed by the head of his Muong guards, Trương Quang Ngọc, and captured on 1 November, while Thiệp was killed. He was then turned over to French officers on 2 November.
