One of the most well-known controversies associated with the Battle of Gettysburg was that of Major General Winfield Scott Hancock and Brig. Gen. Henry Jackson Hunt, two of the most able and famous officers who served with the Army of the Potomac. Known today as the Hunt- Hancock controversy, it centered around the use of Union artillery on July 3, 1863 during both the great cannonade and the repulse of Pickett's Charge. This book will explore the history of the controversy (from the events of July 3 through its continuation into the post-war years), and offer a critical analysis of the generals respective arguments and how their actions impacted the July 3 battle.
