Edith,    In my opinion the best bbok by far concerning Antietam/ Sharpsburg is "Landscape Turned Red" by Stephen W. Sears, ISBN0-89919-172-X.    There are also hundreds of websites on the subject, my suggestion is use "Google" search engine. Below are a few of the site links.                            Marc F.
