Gettysburg is America's most famous battle. Fought on the first three days of July 1863, it was one of the largest and by far the bloodiest of the Civil War. Yet the importance of this great conflagration cannot be measured in numbers alone, for Gettysburg also represented a pivotal moment in the war. The battle ended General Robert E. Lee's second invasion of Union soil, and never again did a Confederate army reach that far north. Join historian John Hoptak as he narrates the fierce action between the Confederate Army of Northern Virginia and the Union Army of the Potomac at such places as McPherson's Ridge, the Railroad Cut, the Wheatfield, the Peach Orchard, Devil's Den, Little Round Top and on Culp's and Cemetery Hills.
