Background
French missionaries had been active in Vietnam since the seventeenth century, and by the middle of the nineteenth century there were perhaps 300,000 Catholic converts in Annam and Tonkin. Most of their bishops and priests were either French or Spanish. Most Vietnamese disliked and suspected this sizeable Christian community and its foreign leaders. The French, conversely, began to feel responsible for their safety. During the reigns of the Vietnamese emperorsBombardment
The 1845 intervention was ordered by Admiral Cécille, the senior French naval officer on station. In 1847, Dominique Lefèbvre secretly re-entered Vietnam. He and another missionary, Duclos, were imprisoned. The arrest of the two missionaries provoked a further confrontation between the Vietnamese rulers and the ships of the French Navy charged with protecting the interests of Roman Catholic missionaries in Vietnam. In March 1847, Cécille sent the 54-gun frigate ''Gloire'' (''capitaine de vaisseau'' Augustin de Lapierre) and the 24-gun corvette ''Victorieuse'' (''capitaine de frégate'' Charles Rigault de Genouilly) to Tourane, with instructions to negotiate for the liberation of the two imprisoned French missionaries and to seek a commitment from the Vietnamese authorities to allow freedom of worship for Roman Catholics in Vietnam.Tucker, 28 Probably because the Vietnamese considered Lefèbvre's return to Vietnam a deliberate provocation by the French, the negotiations failed. Discussions dragged on without result, and on 15 April 1847 six Vietnamese corvettes attacked the two French ships in the Bay of Tourane. In the brief action that followed, the French sank four Vietnamese corvettes and disabled a fifth, and inflicted nearly 1,200 casualties on the outclassed Vietnamese sailors.Thomazi, ''Conquête'', 23. According to the French, the Vietnamese spun out the negotiations to win time to assemble a fleet, and then treacherously attacked the two French warships without warning. Colonel Alfred Thomazi, the historian of the French conquest of Indochina, also claimed that the Vietnamese first attempted to lure the French officers to their deaths: Thomazi gave the following description of the battle in Tourane Bay: Lefèbvre was released by the Vietnamese authorities either before or shortly after the battle (the sources differ).Significance
The Vietnamese naval defeat at Tourane dramatically demonstrated the technological superiority of the French warships over the antiquated vessels of the Vietnamese fleet. In the eyes of many thoughtful Vietnamese, it demonstrated that the kingdom's blind adherence to the values and traditions of the past had left it painfully vulnerable to European coercion, and spurred calls for modernization. Harassment of the Christians eventually provided France with a pretext for attacking Vietnam. The tension built up gradually. During the 1840s, the persecution of Roman Catholic missionaries in Vietnam evoked only sporadic and unofficial French reprisals, such as that taken by de Lapierre and Rigault de Genouilly in 1847. In 1857, however, the execution of two Spanish Catholic missionaries by the emperor Tự Đức led directly to French intervention in Vietnam. In September 1858, a joint French and Spanish naval expedition landed at Da Nang. Its commander was Admiral Charles Rigault de Genouilly, one of the two French naval captains involved in the 1847 incident. The resultant Cochinchina campaign inaugurated the era of French colonial rule in Vietnam.Notes
