When he enlisted, he was 5 feet 4 inches tall, and had a fair complexion, light eyes, and light hair (4).
He enlisted and was mustered into service on 3 October 1861 (1, 4). He was enlisted for three years, by Lieutenant Pierce, at Philadelphia, Pennsylvania (4). He was a private in company F (1, 5).
He was discharged at Philadelphia, Pennsylvania, on writ of habeas corpus, because he was under age (1, 3, 4). (I assume his inclusion in the company F Register of Deserters (2) is a mistake.) He was a private, in company F (5).
