The "Articles of transfer of Arkansas Volunteers to the Confederate States" was signed on July 15, 1861, by Brig. Gen. William J. Hardee, on behalf of the Confederate States, and Gov. Henry M. Rector, Benjamin C. Totten, and Samuel W. Williams, on behalf of the Military Board of the State of Arkansas. Under the terms of the Articles, the Arkansas State Troops would be mustered into Confederate service for a period of twelve months, less the time already served in State service.
The 6th Arkansas Infantry was mustered into Confederate service on July 26, 1861, at Camp Hardee, near Pocahontas, Arkansas. Lieutenant Fulton was due pay from the Confederate States from that date.
David C. Fulton was mustered into State service with his company on June 3, 1861, at Little Rock, and was elected second lieutenant on June 8, 1861. He was mustered into Confederate service with his company on July 26, 1861, at Camp Hardee. He was promoted to first lieutenant on October 15, 1861. He resigned his commission on April 28, 1862. No reason is stated, but, given his age (47) and the rigors of camp life, he probably resigned on a surgeon's certificate of disability. There is no record of any subsequent service in the Confederate army.
