Dupré, Marie-Jules

▪ French naval officer

born Nov. 25, 1813, Albi, Fr.

died Feb. 8, 1881, Paris

      French naval officer who served as governor of French Cochinchina (southern Vietnam) in 1871–74. Despite official policy opposing imperialistic expansion, Dupré attempted to establish French dominance in Tonkin (northern Vietnam) with the hope of promoting trade and of finding a commercial route into China.

      Dupré graduated from the naval school in 1831 as a midshipman; he attained the grade of lieutenant commander in 1847 and became a commander in 1854. He served in the Crimean War and took part in expeditions to Syria and Cochinchina in 1860. In 1864 he was named governor of Réunion. By 1867 he had attained the rank of rear admiral. In 1870 he commanded a naval blockade of ports in China and Japan, which the French were trying to keep closed to the Germans.

      Dupré became governor of Cochinchina in April 1871. When a French trader, Jean Dupuis (Dupuis, Jean), became involved in a dispute with Vietnamese authorities as the result of efforts to use the Red River as a commercial route in 1873, Dupré seized the opportunity to extend French influence, disregarding the reluctance of the government in Paris. Instead of sending a diplomatic mission to Hanoi, he exceeded his authority and sent a small force under the command of Lieutenant Commander Francis Garnier (Garnier, Francis) to Tonkin in response to Dupuis's appeal for help. After a brief period of success that included Garnier's capture of the Hanoi citadel, Dupré decided to seek some diplomatic agreement with the Vietnamese court rather than to rely on force. Before his envoy, Paul-Louis-Félix Philastre (Philastre, Paul-Louis-Félix), had reached Hanoi, Garnier was killed. Dupré then disavowed his subordinates' actions.

      After Garnier's death, Philastre negotiated a treaty by which the Vietnamese emperor, Tu Duc, agreed to recognize the French annexation, in 1867, of the three western provinces of Cochinchina and to open the northern centres of Hanoi, Haiphong, and Qui Nhon to foreign commerce. The treaty was ratified in 1874, but Tu Duc took advantage of continued antiexpansion feeling in France and ignored the treaty, and France failed to convey news of the treaty to China until the Chinese launched a bandit-suppression campaign in northwest Tonkin in 1877. When, by 1882, political attitudes in France had changed, the Vietnamese refusal to honour Philastre's treaty led to conflict, and in 1883–85 all of Vietnam passed under French rule.

      Dupré's role in the affair of 1873, however, had led to his recall from Cochinchina in 1874. Though chiefly remembered for his attempt to expand into Tonkin, he had been an energetic administrator of the internal affairs of his domain. He had sponsored a public-health program, planned realistic public-education policy, and presided over the establishment of the Collège de Stagiaires (College of Probationers) in Saigon for the legal training of French administrative personnel. He also had supported Philastre's efforts to preserve the Vietnamese legal code.

      After his return to France, Dupré was appointed a vice admiral and named maritime prefect of Rochefort, and later of Toulon, a position that he held until his retirement in 1878.
