Hi Jack -
I live 5 minutes from Crown Hill Cemetery and the Confederate Burial Mound here in Indy.
There are several large metal plaques on the burial mound listing all (most?) of the POWs buried there. When I get the chance I will swing by and look for Pvt Wm B Daniel and if there, will take some digital photos for you.
What was his unit once again?
y.v.o.s.,
Kenneth Byrd
