"While a political refugee in London, former Confederate general John G. Walker wrote a history of the Civil War west of the Mississippi River. Walker’s account, composed shortly after the war and unpublished until now, remains one of only two memoirs by high-ranking Confederate officials who fought in the Trans Mississippi theater. Edited and expertly annotated by Richard Lowe—author of the definitive history of Walker’s Texas division—the general’s insightful narrative describes firsthand his experience and many other military events west of the great river."Others directly Civil War-related:
