Around 125,000 troops from North Carolina served in the Confederate Army, and about 15,000 North Carolina troops served in Union Army regiments, with many other men leaving the state to join Union regiments elsewhere. Over 30,000 North Carolina troops died from disease, battlefield wounds, or starvation. Elected in 1862, Governor Zebulon Baird Vance tried to maintain state autonomy against Confederate President Jefferson Davis in Richmond. The state government was reluctant to support the demands of the national government in Richmond, and the state was the scene of only small battles. In 1865, Durham County saw the largest single surrender of Confederate soldiers when Joseph E. Johnston surrendered the Army of Tennessee and all remaining Confederate forces still active in North Carolina, South Carolina, Georgia, and Florida, totalling 89,270 soldiers.
