Recently, I asked on Facebook about the salaries earned by Civil War soldiers, and those who responded pointed to this source: Albert A. Nofi’s book, A Civil War Treasury, Being a Miscellany of Arms & artillery, Facts & Figures, Legends & Lore, Muses & Minstrels, Personalities & People.
That’s quite a title, but it is a deliberate attempt to mirror the kind of 19th century books which contained an endless variety of facts and information. It really is a wonderful miscellany, and I have found countless gems of information about innumerable topics. For example, what the men ate, what is a vivandiere, how many immigrants served on each side and where they were from, etc. etc.
Originally published in 1992, it is available on amazon.com used for very little. But its value is very great — highly recommended.
