A book published in 1958, written by A.A. Hoehling gives several references to letters, diaries and journals written by women and one little girl (Carrie Berry) who lived in Atlanta during the Civil War. It's called "Last Train From Atlanta". I don't know if it's been reprinted or not. I read our library's copy.

It seems as if I've read some of Carrie Berry's diary online, but don't recall the website.
