Gettysburg map, can be scaled to KS size

Here is a 1:12000 map, which can be scaled to 1:8000 for Kriegsspiel.

I am looking for a 1:8000 map of anyplace in the United States which can be reasonably used for a Civil War Kriegsspiel, but i simply can't find anything. I can find plenty of maps at 1:25000 scale, but I need something that looks good at 1:8000 when blown up to approximately 50"x50".

Does anyone have anything that comes close?

God forbid I am forced to run a Napoleonic scenario...

Neal there are 2 places that you at. USGS has them and also National Geographic does too. I think you can adjust the scale to what you need on the USGS site.

Hoe that helps.
