Hi George -
only idea I have is to methodically peruse the CSR microfilms for all of the men in Moorman's Battalion. That way you can see who was wounded/killed/missing, etc.
Does MDAH have the Moorman's CSR microfilm there in Jackson??? If not, I think you might be able to borrow it via interlibrary loan or buy it from the NARA business office in DC..????
