The town dates back to the late eighteenth century, when, according to local legend, it was founded by two brothers of Daniel Boone. Unsurprisingly, given its proximity to Antietam, it saw major fighting during the Civil War, and housed numerous soldiers following Antietam. In recent history, Boonsboro is primarily an agricultural center, but it's also just a nice historic town for a leisurely lunch or dinner, and perhaps a stop at one of the museums, while exploring the area.
