I spend more time than any man probably should watching old Civil War documentaries on Youtube.  This four part documentary from 1958 focuses on the naval campaigns of the conflict.  What I find interesting in these films is not only the information contained in them but the look, feel, and sound of the documentaries themselves.  They are themselves primary artifacts in that they often tell us as much about their own era as they do the Civil War’s.  Of course some day they will say the same thing about us and the sesquicentennial.
