• A Field Guide to Gettysburg, Second Edition: Experiencing the Battlefield through Its History, Places, and People by Carol Reardon & Tom Vossler (UNC Press, 2017).
Although it doesn't feel like it has been that long, it's already been four years since the first edition of A Field Guide to Gettysburg was published. Since then, authors Reardon and Vossler have put out A Field Guide to Gettysburg, Second Edition Expanded Ebook: Experiencing the Battlefield through Its History, Places, and People that I haven't seen, as well as an Antietam guide of great merit that has been reviewed here on the site. The new print version of the Second Edition "will lead visitors to every important site across the battlefield and also give them ways to envision the action and empathize with the soldiers involved and the local people into whose lives and lands the battle intruded."
More from the description: "Divided into three day-long tours, this newly improved and expanded edition offers important historical background and context for the reader while providing answers to six key questions: What happened here? Who fought here? Who commanded here? Who fell here? Who lived here? And what did the participants have to say about it later? With new stops, maps, and illustrations, the second edition of A Field Guide to Gettysburg remains the most comprehensive guide to the events and history of this pivotal battle of the Civil War." I hold these Reardon and Vossler guides in very high regard.
