looking for information on three soliders who were in the Mathewes Heavy Artillery. Info is hard to come by.

George W. Martin I have found who was in Co. B MAtthews South Carolina Artillery and Jefferson Keys.
W. G. Dooms is listed as private in the same Artillery and have not been able to locate any details

the most iimportant detail that I am looking for is to which battles they fought in and were wounded. These three are buried in High Point NC, having died in the General Hospital #3 in March or April 1865.

any information on these men is appreciated as working on where the 50 men who died in the hospital at High Point.as to where they came and what they died of.
