Some time ago, I recall hearing that a number of Gettysburg civilians died of disease in the aftermath of the battle, but I don't remember where I saw or heard this. I'm looking for more information about this because I would like to use this in an article I'm writing. I'd like to know how many civilians got sick and how many died. If anyone has information (like from a book), I need to know which book so I can cite the reference. Thanks.
