‘Gettysburg's Most Hellish Battleground: The Devil's Den, July 2, 1863’ by Phillip Thomas Tucker is dense, historically-rich account of this pivotal and bloody battle of the American Civil War. Many historians have tackled the battle at Gettysburg (and often focused on more “famous” battles), but none of the books I have read are as detailed, and none cover the battle at Devil’s Den, located at the southern edge of Houck’s Ridge, as Tucker does. This book presents a much more holistic view of the important commanders, leaders, and what actually occurred during that fateful three-day period. Tucker outlines the mistakes made by both the Union and Confederate armies in a non-biased manner and offers enough background information to paint a stark picture of the choices and events that led up to this devastating battle.Initially, Tucker offers the reader insight into how the Confederate army used the Army of Northern Virginia and the Texans, commanded by Major General John Bell Hood. The strategic and tactical maneuvers and complexities of planning by the leaders, as well as the manipulations and politics of the times are fascinating and contribute to the backstory of what led to this devastating three-day battle. This behind-the-scenes account leaves one wondering – was it worth the thousands of deaths that resulted from the battle at Gettysburg?The treacherous landscape, strewn with boulders and alcoves, Confederate sharpshooters attempted to replicate their success. The Union Army made a valiant effort, resulting in numerous casualties for both sides. Seeing the visual images of the body-strewn battleground was disturbing.Today this location is a tourist attraction, but during the Civil War it was the site of a brutal massacre that led to many casualties for both the Union and Confederates armies. Tucker offers insight, photographs, and a level of research and depth that many historical books lack – yet, this book was easy to understand and was “light” enough to read in just one sitting. I literally could not put this book down, as I truly enjoy historical books, particularly about the Civil War. I highly recommend this book for anyone interested in the Civil War, who would like to learn more about an often-overlooked yet significant battle at Gettysburg. Tucker is an incredibly knowledgeable historian and writes with depth and detail.
