Fort Fetter, created circa 1777 by fortifying Michael Fetter's barn, served throughout the American Revolutionary War as a fortified structure defending local settlers in this part of Bedford County against Indian incursions between 1777 and 1782. On the morning of 03 June 1781, a detachment of Bedford and Cumberland County militia left its garrison and headed north in response to reports of recent Indian attacks on a number of settlers. About a mile from the fort, the militia were ambushed by a party of Indians led by British Lieutenant Robert Neiles. In the Engagement of Frankstown, the militia suffered eleven killed and five wounded, and ten militia were taken prisoner, while the British and Indian party suffered no casualties.
