Charles R. Pomeroy, Jr. (1842-1864) was the son of C. R. and Elizabeth Pomeroy of Pomeroy, Ohio. He enlisted as a private in Company F, Ohio 18th Regiment, on 22 April 1861, mustered out of that unit in August, and enlisted as a private in Company I, 33rd Regiment, Ohio Volunteer Infantry, on 11 October 1861. He was promoted to first sergeant on 31 October 1861, to second lieutenant on 1 January 1862, and to first lieutenant on 15 March 1864. Pomeroy was captured at the Battle of Chickamauga in 1863 and was interned at Libby Prison for several months. Because he was assisting a wounded Union officer at the time of his capture, he was mistaken for a physician. When his captors exchanged him as a doctor, he surrendered to Union authorities in Washington, D. C., for "impersonating an officer." Rather than punishing Pomeroy, he was commended by the Secretary of War for securing his early release and returning to his unit. Pomeroy was leading his unit, Company A, in a charge on Confederate breastworks near Atlanta when he was killed on August 13, 1864.
