DE TROBRIAND, Philippe Regis, soldier, born in the Chateau des Rochettes, near Tours, France, 4 June 1816. His full name and title were Philippe Regis Denis de Keredern, Baron de Trobriand ; but, on becoming an American citizen, he modified the name and dropped the title. His early education was for a military career. He studied at the College Saint Louis in Paris, the College of Rouen, where his father was in command, and the College of Tours; but the revolution of 1830 changed his prospects, and he was graduated at the University of Orleans as bachelieres lettres in 1834, and at Poitiers as licenci6endroit in 1838. He came to the United States in 1841, edited and published the " Revue de nouveau monde" in New York in 1849'50, and was joint editor of the "Courrier des EtatsUnis" in 1854'61. On 28 August of the last-named year he entered the National army as colonel of the 55th New York regiment. He was engaged at Yorktown and Williamsburg, commanded a brigade of the 3d army corps in 1862'3, and was at Fredericksburg, Chancellorsville, and Gettysburg. He was made brigadier general of volunteers in January 1864, and commanded the defenses of New York City from May till June of that year. As commander of a brigade in the 2d army corps he was at Deep Bottom, Petersburg, Hatcher's Run, and Five Forks, and was at the head of a division in the operations that ended in Lee's surrender. For his services in this campaign he was brevetted major general of volunteers on 9 April 1865. He entered the regular army as colonel of the 31st infantry on 28 July 1866, was brevetted brigadier general, U. S. army, 2 March 1867, and commanded the district of Dakota in August of that year. He was transferred to the 13th infantry on 15 March 1869, and commanded the district of Montana, and afterward that of Green River. He was retired at his own request, on account of age, on 20 March 1879, and is now (1887) a resident of New Orleans, La. He has published "Les gentils hommes de l'ouest," a novel (Paris, 1841), and "Quatre ans de campagnes a l'armee du Potomac" (2 vols., Paris et Bruxelles, 1867).
