[Bates' service summaries are sometimes inaccurate. See, for example, special order 4, HQ 91st PA, 16 February 1864, which records transfers Bates missed. In some cases the transcriber may also have misread the handwriting; Frederick Henry, for example, seems to be Bates' Frederick Hentz.] - Catalogue
