The index contains names not only of signers of the letters but also of persons mentioned in the letters. The index card gives the name of the person, sometimes his rank in the army, and the file numbers where the letters may be found. For a variety of reasons, many of the letters indexed are no longer in the series of letters received, some are in other collections, or were lost or destroyed.
