Folly Island was used as the base for taking Charleston. It is just south
of Morris Island where the fighting occurred. The sources by Legg and Smith
deal mostly with African American troops, especially the 55th Mass. My
book deals with all the union forces on Folly and has some good information
on the blacks. I have not yet gotten Steve's book, but I suspect it is an
excellent source. I live on Folly Island. I consider the film to be quite
good. There were a few scenes where I could tell they had used Civil War photog
raphs as their starting point.
