[3] The Vietnamese defenders of Vĩnh Long fell back to a fortified earthwork at My Cui, 20 kilometres (12 mi) west of Mỹ Tho.

Admiral Bonard sent two columns under the respective command of capitaine de vaisseau Desvaux and Colonel Carlos Palanca Gutiérrez to capture My Cui.

Palanca Gutiérrez's column, which consisted of 200 Spanish troops, a company of Turcos and a section of artillery, marched directly on My Cui from Vĩnh Long.

Lieutenant de vaisseau Vergnes, who was watching the arroyos around Mỹ Tho with a detachment of fusiliers-marins, intercepted and inflicted a further defeat on the retreating Vietnamese.
