I can't give you specifics, but southern Ohio was very active in assembling and training Union troops that were sent south and also down the Ohio River to defend the Kanawha River valley and ended up at the Battle of Gauley Bridge in West Virginia. There is a multitude of websites about the history that cover the areas and Google will get you about anything you want to know.
If you run across things like letters home from the soldiers, a lot of times you can find better descriptions of actual locations than the history books provide.
