So in my continuing efforts at visiting the rare spots of the war I went to Smithland to see what I could see. There is not much. Smithland is a small town. I think there was just a warning light in town, not a traffic light, just a flashing yellow light. But on the hill south of town are the remains of the Union Fort Smith. They are pretty well preserved, I've heard that they are the best preserved entrenchments in Kentucky but I'm not sure I'd go that far.
I doubt I'll ever visit Smithland again but it was nice to see it once.
