Born near
Indianapolis,
Indiana, to father Jacob Pile and mother Comfort Williams, Pile completed preparatory studies, studied theology, became a minister in the
Methodist Episcopal Church, and was a member of the
Missouri conference. At the outbreak of the Civil War, he entered the Union Army as
chaplain of the
1st Missouri Light Artillery Regiment in 1861, serving under
Colonel Clinton B. Fisk. He was made
captain, Battery I, 1st Missouri Light Artillery, on March 1, 1862, and promoted to
lieutenant colonel of the
33rd Missouri Volunteer Infantry on September 5, 1862. He was promoted to the rank of
colonel on December 23, 1862, then to
brigadier general of volunteers in 1863. He commanded the Post of Port Hudson, District of Baton Rouge and Port Hudson, Department of the Gulf from December 26, 1864, to February 13, 1865; and commanded the 1st Brigade, 1st Division, United States Colored Troops, District of West Florida, Department of the Gulf from February 19 to April 25, 1865. He was promoted to
brevet major general in 1865. Details in records are unclear. Three of the regiment's batteries were at Fort Donelson, and apparently Pile was too. Made a battery commander, it is stated that he was at Shiloh; however, the records indicate that it was under the command of Lieutenant Charles H. Thurber. He was, however, in the Corinth, Mississippi, operations which followed. As an infantry commander, he fought at Devall's Bluff and took part in the Yazoo River expedition. Named a brigadier general, he took up recruiting duties in St. Louis and was not particularly concerned to whom–unionist or secessionist–the slaves he inducted belonged. After serving in a post command, he led a black brigade at Mobile. For the attack on Fort Blakely, he was brevetted major general, and he was mustered out on August 24, 1865. Pile was elected as a
Republican to the
United States House of Representatives from Missouri in 1866, serving from 1867 to 1869, being unsuccessful for reelection in 1868. There, he served as chairman of the
Committee on Expenditures in the Post Office Department from 1867 to 1869. Afterward, he was nominated to be
Ambassador to Venezuela and
Brazil by
President Ulysses S. Grant in 1869, but his nomination was withdrawn and he was instead appointed
Territorial Governor of New Mexico; he served from 1869 to 1871. Pile was successfully appointed Ambassador to Venezuela by President Grant in 1871, a post he held until 1874. ==Gallery==
