The
Battle of Kỳ Hòa (Trận Đại đồn Chí Hòa) on 24 and 25 February 1861 was an important French victory in the
Cochinchina campaign (1858–62). This campaign, fought between the French and the Spanish on the one side and the Vietnamese on the other, began as a limited
punitive expedition and ended as a French war of conquest. The war concluded with the establishment of the French colony of
Cochinchina, a development that inaugurated nearly a century of French colonial dominance in Vietnam.
