Its members were recruited in Mobile and the counties of Washington, Marengo, Baldwin, Montgomery, and Greene. In March, 1862, it moved to Corinth and, assigned to General Gladden's Brigade, was conspicuous in the Battle of Shiloh. On the return to Corinth, the regiment was reorganized, saw light action at Farmington, then was ordered back to Mobile. Here it was trained in heavy artillery and brigaded under Higgins, Page, and B.M. Thomas. The 21st participated in the battles of Forts Gaines and Morgan and Spanish Fort. Six companies were captured at Fort Gaines and two at Fort Morgan, but the two at Fort Powell blew up and evacuated that post. The men were captured at Fort Gaines were later exchanged, the others were not. It lost thirty-one percent fof the 650 engaged at Shiloh, had 10 killed and 25 wounded at Spanish Fort, and surrendered on May 6, 1865, about 250 strong. The field officers were Colonels Charles D. Anderson and James Crawford; Lieutenant Colonels S.W. Cayce, A.J. Ingersoll, C.S. Stewart, and James M. Williams; and Majors Charles B. Johnston, F.J. McCoy, and Frederick Stewart.
