Amos F. Corliss was born around 1843 in Vermont to Hiram and Prudence Corliss. His father was a farmer who owned $1,000 of real estate in 1850. A decade later, his father owned $1,500 of real estate and $190 of personal property. The family lived in Corinth, Vermont, and Corliss attended school there before beginning work as a farmer. Corliss enlisted in the Union army on September 15, 1862, and he mustered in as a private in Company D of the 15th Vermont Infantry on October 22, 1862. According to his enlistment records, he was 5 feet, 8 3/4ths inches tall, with black hair and hazel eyes. The regiment helped defend Washington, D.C., and the men mustered out when their 9-month term expired on August 5, 1863. Corliss returned to Vermont after leaving the army. He applied for a federal pension on November 8, 1866, and began receiving payments soon afterward. He died of consumption in Topsham, Vermont, on December 20, 1867.
