15th Regiment, Mississippi Infantry
15th Infantry Regiment, organized at Choctaw, Mississippi, in May, 1861, contained men from Holmes, Choctaw, Quitman, Montgomery, Yalobusha, and Grenada counties. The regiment was active at Fishing Creek, Shiloh, Baton Rouge, and Corinth, then was placed in Rust's, Tilghman's, and J.Adams' Brigade. After serving in the Vicksburg area, it joined the Army of Tennessee and participated in the Atlanta Campaign, Hood's winter operations, and the Battle of Bentonville. This unit had 34 officers and 820 men on January 7, 1862, and lost 44 killed, 153 wounded, and 29 missing at Fishing Creek. Many were disabled at Peach Tree Creek and Franklin, and only a remnant surrendered in April 1865. The field officers were Colonels Michael Farrell and Winfield S. Statham; Lieutenant Colonels James R. Binford, J.W. Hemphill, and Edward C. Walthall; and Majors William F. Brantly, James B. Dennis, Russell G. Prewitt, and Lamkin S. Terry.

Regiment Companies with the County of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
A list of companies was not available.
