“The Confederacy was not just a separatist movement, it was an existential threat to the very idea of freedom, liberty, the pursuit of happiness—it could not be abided, and that conflict left so many dead that the streets of Gettysburg were once littered with so many corpses that it was weeks getting them into the mass graves. The town was covered in the rotting dead and the stench of them, all lying underneath the Pennsylvania sun. . . . a town where, once the armies moved on to fight again elsewhere, there weren’t enough people left alive to wash the blood from the streets and the gore from the walls—that’s what civil war means.” – Noah Caldwell-Gervais, The Lincoln Highway: Across America on the First Transcontinental Motor Route (emphasis in original)
