The Twenty-first Mississippi Infantry Regiment, the final component of the future Barksdale’s Mississippi Brigade (the 13th, 17th, 18th and 21st), arrived Nov. 12 and joined Evans’s Seventh Brigade.

The Twenty-first was composed of eleven companies which had all, according to Howell, “tendered themselves independently to President Davis for service to the close of the war and on being accepted went to Virginia as rapidly as possible.”

The Twenty-first was commanded by Col. Benjamin Grubb Humphreys, a Delta planter and slave-holder, who would become Mississippi’s first post-war governor.
