Sergeant William Barnes Junior was a member of Company F of the 7th Mississippi Infantry. Company F appears to have been from Marion County, Mississippi. He was wounded in the thigh at 6:30 pm on April 6, 1862 at the Battle of Shiloh and taken prisoner.

Usually men like this were taken to Union field hospitals. Thanks to a newspaper from the Cincinnati Gazette dated April 18, 1862 I see him aboard the "Magnolia" which was a steamer rented by the United States Sanitary Commission for the purposes of bringing back both wounded Union and Confederate prisoners of war to various towns along the Ohio and Mississippi Rivers. In this case it was Camp Dennison in Cincinnati, Ohio.

He was admitted to the Post Hospital at Camp Dennison for his wound and after recovery was transferred to Camp Chase where he was held prisoner until the Dix-Hill Cartel agreement in September 1862. He was taken by steamer on the "John H. Done" to Vicksburg, Mississippi and paroled and exchanged.

He later requested a transfer to the cavalry because of his wound but was denied.
