Two known-identified 9th MS boys who fought at Franklin are buried at McGavock. The 9th MS also fought with the 7th, 10th, 41st and 44th MS Infantries, and the 9th Mississippi Sharpshooters Battalion.
Here is an early picture of the 9th Mississippi regiment, taken in 1861 at Pensacola.
Picture credit: Arms and Equipment of the Confederacy (p. 263 & 31).
Though this picture of the 9th MS is taken in 1861 at Pensacola, it does not take much to imagine that this scene was replayed again in Spring Hill, TN, on November 29, 1864, one day before the bloody Battle of Franklin.
