Terry,
Glad the Springfield Prison info was of some interest. If this will be your first trip to NARA in DC, let me know when you are in the planning phase for your trip as I have some suggested do's and don't's for you that might help make your trip more efficient. Do you have a copy of the NARA book compiled by Bethel, "Preliminary Inventories of the War Department Collection of Confederate Records? My email address is: hughkeen@hotmail.com
