The Penns Creek Massacre on October 16, 1755 was the first of a series of deadly raids on Pennsylvania settlements by Native Americans allied with the French in the French and Indian War. A marker on the bank of Penns Creek north of Selinsgrove commemorates the massacre of 14 settlers and the capture of 11 more. In response to this and other Indian actions that day, Fort Augusta, Sunbury, Pennsylvania, the largest of Pennsylvania's frontier forts, was built in 1756 as a result of this conflict.
