If it doesn't glorify and romanticize the War Against Secession (the "civil war"), it doesn't fit the official narrative. But the bloodletting at Gettysburg 150 years ago this July was anything but glorious. Arguing that national memory often requires a walling off of the horrors and instead only seeing the alleged nobility of sacrifice, author of America Aflame, David Goldfield, is today's guest. He sheds a great deal of light on the realities and not the myth of history. Sobering.
