Hoa Lư is a city in the Red River Delta of northern Vietnam.
Hoa Lư Ancient Capital is located in Trường Yên Commune (vi).
[1] During the Nguyen dynasty, in August 1884 in the Tonkin campaign, the allegiance of Ninh Bình was of considerable importance to the French, as artillery mounted in its lofty citadel controlled river traffic to the Gulf of Tonkin.
Although the Vietnamese authorities in Ninh Bình made no attempt to hinder the passage of an expedition launched by Henri Rivière in March 1883 to capture Nam Định, they were known to be hostile towards the French.
In November 1883, on the eve of the Sơn Tây campaign, the French occupied the citadel of Ninh Bình without resistance and installed a garrison.
