The United States Army's Center of Military History in June 2013 published a new concise monograph on the Gettysburg Campaign.
Authors Carol Reardon and Tom Vossler examine the operations that culminated in the pivotal and devastating three-day Battle of Gettysburg, pitting the Union Army of the Potomac under Major General George G. Meade against the Confederate Army of Northern Virginia under General Robert E. Lee.

Her publications include Pickett's Charge in History and Memory (1997) and With a Sword in One Hand and Jomini in the Other: The Problem of Military Thought in the Civil War North (2012). Tom Vossler is a retired U.S. Army colonel and former director of the U.S. Army Military History Institute. Since 1998, he has worked as a licensed battlefield guide at Gettysburg National Military Park where he conducts military staff rides, civilian corporate leadership seminars, and general interest tours of the battlefield.
