During the first three days in July, 1863, two armies, one dressed in blue and the other dressed gray, waged a series of battles that would claim over 50,000 casualties at the small town of Gettysburg, Pennsylvania. Today, over 1,100 statues and monuments tell the stories of these three days that determined the future course of America’s history. The late Civil War historian, Albert Castel, winner of the prestigious Lincoln Prize, described these Gettysburg photographs as, “stunningly beautiful. A remarkable achievement.”
