Vĩnh Long
Ten days later, Bonard anchored off Vĩnh Long with a flotilla of gunboats and eleven transport vessels and disembarked a Franco-Spanish landing force of 1,000 troops. In the afternoon and evening of 22 March, the French and Spanish assaulted the Vietnamese batteries entrenched before Vĩnh Long and captured them. On 23 March they entered the citadel of Vĩnh Long. Its defenders retreated to a fortified earthwork at My Cui to the west of Mỹ Tho, but were soon overrun and forced to flee. Vietnamese casualties at Vĩnh Long and My Cui were heavy.
