Shenandoah 1862: Stonewall Jackson's Valley Campaign is a 2008 book written by Peter Cozzens and published by the University of North Carolina Press. The book studies Jackson's Valley campaign, an 1862 operation during the American Civil War. "Shenandoah 1862" is sourced to both primary and secondary sources, including previously unpublished primary source material. While previous works on the campaign generally focused on the Confederate perspective of the campaign, Cozzens's work also incorporates Union material. It also challenges the traditional interpretation of inept Union leadership and an outstanding performance by Confederate commander Thomas J. "Stonewall" Jackson, although one reviewer viewed Cozzens's criticism of Jackson as too harsh. While a reviewer for the "Virginia Magazine of History and Biography" noted several minor errors in the work, most reviewers praised the work for its objectivity and use of primary sources, with some predicting that "Shenandoah 1862" would become the go-to work about Jackson's Valley campaign. The book was also described as demonstrating revisionist tendencies.
