The remains from Ft. Pillow were removed in 1866 to the National Cemetary in Memphis. Individual gravesites are problematical due to the two previous burials/disenternments before the move. I've never found a already complete list of the casualties. You'll probably have to check the muster books for each unit and tabulate them yourself. The Books for the Tennessee units are held by the Tn State Museum. I'm not sure if they have the USCT books or not.
