William Marvel wrote a book called "Andersonville, The Last Depot" he used extracts from my great grandfather's dairy that were sent to the park by an aunt many years ago. My brother saw the bibliography when he read the book. My understanding from the information they sent me about my great grandfather is that there are copies of some of these diaries on sale at the park. Perhaps if you wrote them they could verify and tell you how to get them. The address I have is: Friends of the Park Box 186 Andersonville, Georgia 31711 Maureen
