Vĩnh Long Province
Admiral Bonard's forces proceeded by capturing Vĩnh Long on 22 March 1862 in a brief punitive operation of Vietnamese guerrilla attacks on French troops around Mỹ Tho. On 10 March 1862 a French gunboat leaving Mỹ Tho with a company of infantry aboard suddenly exploded. Casualties were heavy (52 men killed or wounded) and the French suspected Vietnamese sabotage by insurgents directed by the governors of Vĩnh Long Province.
