Your welcome! I thought it was interesting since I've never seen a source provide a total figure of Confederate casualties in this battle, just estimations. While not 100% conclusive- it seems very possible that these figures (whether 207 killed and 904 wounded...or 904 killed and wounded) could very well be the official total given by the medical director of the Confederate army. It's in the same ballpark of the current estimations.

Also, the report by Dr. Stuckslager seems to be an excellent source describing the conditions encountered by Union medical personnel and the wounded while inside Confederate lines.
