M35gibson,
Maps are not my forte, but I will give you a list of map sources.
-The American Civil War Homepage
sunsite.utk.edu/civil-war/warweb
After clicking onto this site, go to "Battles and Campaigns", this will bring you to "regional or general". The 3rd selection is "Civil War Battle Maps Locator" Click on this, which will take you to Search for Civil War Battles, by "MapMuse's Interactive Map and Directory Locator Service." Go to the green drawing of the U.S, click on the site of your choice. You are on your own from there.
-Civil War Maps - Related Resources
memory.loc.gov
Click on this site, it will take you to the Library of Congress American Memory. In the search box to the left, type in civil war maps. A listing of 2,109 maps pops up. The LOC is my favorite site!

My parents gave me the gargantuan book, The Official Military Atlas of the Civil War. It has 821 maps - which include topographical maps, 106 engravings and 209 drawings.
Hope this helps!
