As a cousin in Kentucky said, they might find their way into the hills and hollows, but they won’t find their way out.
While the Confederacy did not mount a full-scale invasion of the Commonwealth after the fall of 1862 (the Heartland or Perryville Campaign), they did have a successful guerrilla campaign throughout the region. Hiding back in the "sticks", these rebels would pop out, hit a target, and disappear back into the hollows before any pursuit could be summoned. Louisville was the Union Army's primary supply depot and new recruit training facility for the Western Theater, yet a number of Confederates managed to hide less than thirty miles away in a large hollow just two miles from the L&N railroad, the Union's main supply artery to the forces campaigning in Tennessee and points south. Today that hollow is known as Guerrilla Hollow; it is located in the Bernheim Forest Nature Preserve and boasts a popular hiking trail.
