While a destructive and bloody war raged across Virginia in the aftermath of Gettysburg, free black families sent husbands and sons to fight with the U.S. Colored Troops. In letters home, even as Lincoln commemorated the dead at Gettysburg, they spoke of a war for emancipation. In The Thin Line of Freedom, acclaimed historian Edward L. Ayers, discusses the end of slavery, Reconstruction, the Freedmen’s Bureau, and new society struggling to emerge. A book signing will follow the program.
