Confederate Military History is a 12-volume series of books written and/or edited by former Confederate general Clement A. Evans that deals with specific topics related to the military personalities, places, battles, and campaigns in various Southern United States, including those of the Confederacy. Written with a heavy Southern slant, the articles that comprise the compendium deal with the famous events of the war. This account is of Stonewall Jackson's famous 1862 campaign in the Shenandoah Valley, where Jackson's "foot cavalry" marched 650 miles in less than 50 days while keeping 3 Union armies bottled up in the Shenandoah Valley. Jackson's success kept the Lincoln Administration nervous enough to keep 50,000 men near Washington D.C. instead of allowing them to join McClellan's Army of the Potomac during the Peninsula Campaign. Jackson then rejoined the Army of Northern Virginia and its new commander, Robert E. Lee, in time to participate in the Seven Days Battles that pushed McClellan's army back.
