Philippe Regis Denis de Keredern de Trotariand
Philippe Regis Denis de Keredern de Trotariand was born near Tours, France, June 4, 1816, son of a baron who supported the Bourbons until 1830, when he resigned his general's commission and retired from the army. Young De Trobriand in a lifetime spanning eighty years pursued, on several continents, the varied occupations of lawyer, poet, author, soldier, and bon vivant. Splendidly at home in all these metiers, he was excelled by few civilians as a regiment, brigade, and division commander of the Army of the Potomac. When Civil War began, De Trobriand, who had married a New York heiress, took out American citizenship and on August 28, 1861, was mustered into Federal service as colonel of the 55th New York, which had been recruited as the "Lafayette Guard." He saw his first hard action on the Peninsula in a brigade of Couch's division of Keyes's IV Corps and his last at Appomattox Court House where he commanded the 3rd Division of the II Corps. In the interval he directed a brigade of the III Corps at Fredericksburg, Chancellorsville, and Gettysburg where he defended the center of Daniel Sickles' line in the celebrated peach orchard. Upon the consolidation of the III Corps he was assigned a brigade of the II Corps, which he led until his promotion to divisional command. He was commissioned brigadier general of volunteers to rank from January 5, 1864, and major general by brevet from April 9, 1865, the date of the surrender of the Army of Northern Virginia. The following year General De Trobriand accepted a colonel's commission in the regular service, although he was in France at the time, writing his Quatre Ans de Campagnes a I'Armee du Potomac, which was translated into English. From 1867 until his retirement he served intermittently with his regiment on the frontier between trips to Europe and in 1875 was a tactful representative of the Federal government in New Orleans during Reconstruction troubles. He remained in the Crescent City after his retirement, spending his summers with his daughter on Long Island. He died at Bayport, New York, on July 15, 1897, and was buried in St. Anne's Cemetery in nearby Sayville.
