Book excerpt: The battle of Gettysburg in July 1863 marked the turning point of the American Civil War. The apex of the Confederacy's final major invasion of the North, the devastating defeat also marked the end of the South's offensive strategy against the North. From this battle until the end of the war, the Confederate armies largely remained defensive. The Artillery of Gettysburg is a thoughtful look at the role of the artillery during the July 1?3, 1863 conflict. Bradley M. Gottfried provides insight into how the two armies employed their artillery, how the different kinds of weapons functioned in battle, and the strategies for using each of them. He shows how artillery affected the ebb and flow of battle for both armies and thus provides a unique way of understanding the strategies of the Federal and Union commanders.
