...and the map at http://www.civilwaralbum.com/atoka/map1.htm
is, I believe, from the Atlas of the ORs, right? I just noticed that Ft McCulloch, Carriage Point, and Preston are mislocated. Ft McCulloch is on the Blue and Texas Road near Nail's Bridge. Carriage Point, as I recall, is on Island Bayou. Preston is in Texas... the south side of the Red River!
I love to nit pick!!!
