During the Indian Wars of the late 18th century, many armies transited Rockhold, most notably General Josiah Harmar en route to his defeat at Kekionga. General Anthony Wayne built Fort Adams in the area of Rockford in the early August 1794, as a temporary relay station and supply depot. Fort Adams was initially garrisoned with 100 soldiers under the command of Lieutenant Underhill. Fort Adams was abandoned in 1796, and is now an archaeological preserve operated by The Archaeological Conservancy. There are no physical remains of the fort.
