 Relatively free from Union occupation until the very end of the war, South Carolina hosted a number of prisoner of war camps.South Carolina also was the only Confederate state not to harbor pockets of anti-secessionist fervor strong enough to send large numbers of white men to fight for the Union, as every other state in the Confederacy did.Among the leading generals from the Palmetto State were Wade Hampton III, one of the Confederacy's foremost cavalry commanders, Maxcy Gregg, killed in action at Fredericksburg, Joseph B. Kershaw, whose South Carolina infantry brigade saw some of the hardest fighting of the Army of Northern Virginia and James Longstreet, the senior lieutenant general in the army, and Stephen D. Lee, the youngest lieutenant general.
