Thomas Duncan

Thomas Duncan (April 14, 1819 – January 7, 1887) was a career officer in the U.S. Army, serving as a lieutenant colonel during the American Civil War. In 1867, he was nominated and confirmed for appointment as a brevet brigadier general in the regular army, to rank from March 13, 1865, for his service in the Civil War.

Biography Duncan was born in Kaskaskia, Illinois. He began his military career at age 13, serving as a private in the Illinois Mounted Volunteers in 1832 during the Black Hawk War.

After his command of the District of Nashville, Duncan was ordered to the Department of the Platte, was stationed successively at Fort McPherson and Fort D. A. Russell, and was afterward in charge of the construction of Sidney Barracks. Lingering complications from his wound compelled him to be medically retired from active service on January 15, 1873.

Thomas Duncan died in Washington, D.C., on January 7, 1887, and was buried in Arlington National Cemetery.
