Do you know if that book contains all of Guerrant's wartime diary entries? I recall there was another book published some years ago with Guerrant's writings as a source (I don't remember the name of it now), but it did not include every entry that Guerrant made. I remember this because he said some interesting things about arms and/or flags in his original writings, that didn't make it into the published book, as told to me by someone who had done research in the diary manuscripts.
Thanks,
