Ian-Greenbrier Bridge,Huntersville,White Sulphur Springs,
and Meadow Bluff are all in present day W.Wa. I do know there is a Confederate mass grave in Lewisburg,Greenbrier Co.,W.Va. I think I recall reading somewhere that there are some Confederate graves at the Greenbrier resort in White Sulphur Springs. You may wish to check their website. Bath Alum and Millboro are in Bath Co.,Va. Dublin is in SW Va.
Unsure of location of Cold Sulphur Springs and Alum Springs.
Also,the Greenbrier resort was used as a hospital.
