The voices of those who witnessed the Battle of Gettysburg and its aftermath with their own eyes - who saw the bloodshed, heard its din, trembled in its crash, struggled with its aftermath - are collected for the first time by Allen C. Guelzo, America's foremost Civil War scholar, in this moving and sobering oral history. This treasure trove of original documents - many never-before published - creates a uniquely personal, day-by-day eyewitness account of the monumental collision at Gettysburg, in the words of the commanders, soldiers, politicians, and civilians from both the North and the South who experienced firsthand the changing course of the Civil War.
