Tuyên Quang ( listen) is a town in Vietnam, the capital of Tuyen Quang province.
The French post at Tuyen Quang was defended for four months against 12,000 troops of the Yunnan Army and the Black Flag Army by two companies of the French Foreign Legion during the Sino-French War (August 1884 to April 1885). The Siege of Tuyen Quang is still remembered as one of the Legion's most celebrated feats of arms, and is commemorated in the first verse of Le Boudin, its principal marching song.
As a town in French Indochina, Tuyen Quang served as a garrison. During the First Indochina War (1946-1954), the Viet Minh made the Legionnaires surrender at the memorial to the Battle of Tuyen Quang.
