Bradford's Company, Mississippi Artillery (Confederate Guards Artillery)
Confederate Guards Light Artillery was organized at Pontotoc and Chickasaw counties. More than 150 officers and men were mustered into Confederate service, and they were soon ordered north. It served in the Department of North Carolina, the Department of Richmond, and later the Department of North Carolina and Southern Virginia. Assigned to J.C. Coit's Battalion of Artillery, the company fought at Swift Creek and Drewry's Bluff and shared in the defense of Petersburg on June 16 and 17, 1864. For a time, one section was stationed at Hicksford, Virginia, then the entire command saw action south of the James River and in the Appomattox Campaign. When the Army of Northern Virginia surrendered in April, 1865, no members of the battery were present. Captains William D. Bradford and John C. Grisham were in command. 
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.
