court under the superintendence of a marshal of
France, who prepared him for admission to St.
Cyr military academy. The revolution of 1830
changed his course and when his father resigned
from the army he entered the college at Orleans
and was graduated B. es L. in 1834 and at Poitiers
in 1838. His father
died in 1840 and he
became Baron de
Trobriand. In 1841
he visited America,
there he met Mary
Mason, daughter of
Isaac Jones, president
of the Chemical bank
of New York city,
and they were mar-
ried in Paris, France,
in January, 1843, and
at once joined the
court of Henry V.,
the Bourbon heir to
the throne of France,
then an exile in Italy. In 1848 or 1849, at the
request of his father-in-law, the couple took
up their residence in America and Baron de
Trobriand established the JBerwe du Nouveau
Monde in New York. In 1851 he was obliged to
return to France and the review was discontinued.
The death of Mr. Jones, his father-in-law, in 1854,
determined his permanent settlement in New
York and he became connected with the Courier
des Etats Unis. He became an American citizen
in 1861 and commanded the 55th New York vol-
unteers (Gardes Lafayette) in the army of the
Potomac. He was transferred, Dec. 21, 1862, to
the command of the 38th N.Y. volunteers and
commanded a brigade in the 3d corps. He en-
gaged in all the battles from Yorktown to and
after Gettysburg and on the second day held the
peach orchard, the central post of General
Sickles's line. He was honorably mustered out
of the service, Oct. 15, 1863. In January, 1864,
he was appointed to the rank of brigadier-general
of volunteers and accepted the commission, May
2, 1864. In May and June, 1864, he commanded
the defences of New York city. He then re-
turned to Virginia and was a brigade conimander
in the 3d corps, engaging in the battles at Deep
Bottom, Petersbm-g, Hatcher's Run and Five
Forks. He commanded the 3d division of the 2d
corps in the final campaign ending in the sur-
render of Lee's army at Appomattox. He was
brevetted major-general of volunteers, April 9,
1865, for " highly meritorious services during the
campaign terminating with the surrender of the
insurgent army under Gen. R. E. Lee," and was
the only Frenchman except Lafayette to hold
that rank in the United States army. When the
volunteer annj' was disbanded he returned to
France. While there he wrote "Four Years
with the Army of the Potomac " in the French
language and it was published in Paris and trans-
lated into English. Returning to America in 1866
he was commissioned colonel of the 31st U.S.
infantry, July 28, 1866, accepting the commission
Oct. 31, 1866. and on March 2, 1867, was brevetted
brigadier -general in the regular army " for gal-
lant and meritorious services during the war."
He commanded the district of Dakota in 1867;
was transferred to the command of the 13th
infantry, March 15, 1869, and commanded the
district of Montana and subsequently the district
of Green River, Wyoming. He conquered a
peace with the Piegan Indians in 1870 and pre-
vented a threatened outbreak of the Mormons
the same year. In 1874 he was ordered to New
Orleans to suppress election troubles. In Janu-
ary, 1875, he dispersed the McEnery legislature
under orders from Washington, but the duty was
performed with tact and firmness and he won the
respect of the opponents to the measure. He
remained in command in New Orleans until
March 20, 1879, when having reached the age
limit, he was retired on his own apjilication. He
inherited the title of count in 1874, and became
head of his family, but he never carried his title
in the United States. General de Trobriand was
a second cousin of Simon Bolivar, the " Wash-
ington of South America," their grancbnothers
having been sisters. He resided in New Orleans,
spending his summers alternately in France and
with his daughter, Mrs. Charles A. Post, at Bay-
port, N.Y., where he died, July 15, 1897.
DETWILLER, Henry, pioneer homoeopathist, was born at Langeubruck, Basle, Switzerland, Dec. 18, 1795. In 1808 he entered L'Institute fran^ais de Ste. Im- mier, and in the spring of 1814 became a student at the medical school of the University of Frei- burg, Baden, where he remained three years. In 1817 he re- solved to visit Amer- ica, expecting to devote four years to the collecting of geo- logical, mineralogical and botanical speci- mens, and he em- barked at Rotterdam
on the ship John of Baltimore, having professional charge of 400 passengers. While visiting Phila- delphia he was persuaded by Bonaparte, Van- damme, Meneges and other companions of the
. Jb-i^JuSdliAy.
