Vĩnh Long
The Vietnamese defenders of Vĩnh Long fell back to a fortified earthwork at My Cui, west of Mỹ Tho. Admiral Bonard sent two columns under the respective command of "capitaine de vaisseau" Desvaux and Colonel Carlos Palanca y Guttierez to capture My Cui. Desvaux's column, which consisted of two companies of Turcos and a detachment drawn from the garrison of Vĩnh Long, set off from Vĩnh Long and approached My Cui via Cai Lay.
