I have "Frank O'Reilly's" 1998-2001 colorful, regimental detail maps on: Fredericksburg, Chancellorsville, Wilderness and Spotsylvania. I picked them up a few years ago at the Fredericksburg gift shop. They are very helpful.
Very regimental detailed, if you need any info on those four battles, with who was where and next to who and left and right etc. Just let me know!
Have a good morning!
