Wilson's Creek, Pea Ridge, and Prairie Grove were three of the most important battles fought west of the Mississippi River during the Civil War. They influenced the course of the first half of the war in that region by shaping Union military efforts while significantly contributing to Confederate defeat. "Wilson's Creek, Pea Ridge, and Prairie Grove", the first book to provide a detailed guide to these battlefields, takes the visitor step-by-step to the major sites of each engagement. With numerous maps and illustrations that enhance the authors' descriptions of what happened at each stop, the book also includes analytical accounts explaining tactical problems associated with each battle as well as vignettes evoking for readers the personal experience of those who fought there. An indispensable companion for the battlefield visitor, this guide offers not only touring information and driving tours of sites associated with the campaigns that led to the battles, but also a brief history of each battle and an overview of the larger strategy and tactics of the military action in which these battles figured.
