On August 4, 1862, the 13th enlisted thirty-eight replacements for their dead and wounded. The new men, most of them in the late teens and early twenties, enlisted for the war at Brookhaven, Mississippi, south of Jackson. A few of them enlisted as conscripts under the new conscript law.

Seventeen of them went to the Wayne Rifles. Fourteen joined the Secessionists, five went to the Spartan Band, two to the Pettus Guards and one transferred from the Second Mississippi Battalion to the Minutemen of Attala.

Two of the Pettus Guards’ new acquisitions were unusual: a father and son named Moore from Water Valley, southwest of Oxford. They were farmers and they enlisted for the war as privates and remained privates.

The son, William R. Moore, was age 20 and single. His father, identified only as E. Moore, was married and 50 years old.
