Corliss was ready to attend Yale when the Civil War started. At his own expense, he raised a company of infantry, which became Company C of the 5th Connecticut Volunteer Infantry. Corliss was promoted to Captain and Commander of the company. He was captured and sent to Libby Prison but was released after a short time. He was wounded at Cedar Mountain. He served with the Mississippi Refugees and Freedmans Bureau until 1869 when he returned to New York City where he was an insurance broker.
