7th Battalion, Mississippi Infantry
7th Infantry Battalion was organized during the early spring of 1862 near Quitman, Mississippi. The unit was assigned to Hebert's Brigade, Department of Mississippi and East Louisiana, and was captured when Vicksburg fell. After the exchange the battalion then served in Mackall's and Sears' Brigade. Few were included in the surrender in May, 1865. The field officers were Lieutenant Colonels L. B. Pardue and James S. Terral, and Major Joel E. Welborn. 
The 7th Battalion Mississippi Infantry (Terral’s) Internet site has a longer history taken from Dunbar Rowland's Military History of Mississippi, 1803-1898.
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.
Company A - (Jasper County Company) - raised in Jasper County
Company C - (Jones County Rebels) - raised in Jones County
Company D - (Mississippi Rangers) - raised in Clarke County
Company E - (Mississippi Sharpshooters) - raised in Clarke County
Company F - (Renovators) - raised in Jones County
Company G - (Covington Sharpshooters) - raised in Covington County
