 A legion historically consisted of a single integrated command, with individual components including infantry, cavalry, and artillery.The concept of a multiple-branch unit was never a practical application for Civil War armies and, early in the war, the individual elements were assigned to other organizations.Organized by Wade Hampton in early 1861, Hampton's Legion initially boasted a large number of South Carolina's leading citizens, including future generals J. Johnston Pettigrew, Stephen Dill Lee, Martin W. Gary, and Matthew C. Butler.
