Dominique Lefèbvre, who had repeatedly come to Vietnam illegally multiple times. The French task force reached
Tourane on 23 March 1847, and demanded that the safety of French nationals be assured and for Thiệu Trị to cease the persecution of missionaries.
The imperial
mandarins put off delivering the emperor's reply and fighting broke out. Thiệu Trị had fortified the coast, but the French forces easily defeated the Vietnamese due to the Nguyễn dynasty's inferior equipment. All of the Vietnamese coastal forts were destroyed and three Nguyễn
junks were sunk before the French squadron sailed away. Thiệu Trị called all missionaries enemy spies and demanded that all Christians should be executed on the spot. The mandarins did not put this order into effect and Emperor Thiệu Trị died shortly afterwards; no missionaries were actually ever executed during his reign.
