David Aspen was the first white settler to live within the borders of what is now Wolf Township. He was scalped during the Revolutionary War, when his and other settlements throughout the Susquehanna valley were attacked by Loyalists and Native Americans allied with the British. After the Wyoming Valley battle and massacre in the summer of 1778 (near what is now Wilkes-Barre) and smaller local attacks, the "Big Runaway" occurred throughout the West Branch Susquehanna Valley. Settlers fled feared and actual attacks by the British and their allies. Homes and fields were abandoned, with livestock driven along and a few possessions floated on rafts on the river east to Muncy, then further south to Sunbury. The abandoned property was burnt by the attackers. Some settlers soon returned, only to flee again in the summer of 1779 in the "Little Runaway". Sullivan's Expedition helped stabilize the area and encouraged resettlement, which continued after the war. Abraham Webster was another of the early settlers to be attacked, only he survived and returned to Wolf Township twelve years after the Big Runaway. His entire family had been killed, but he returned with a new wife and re-established his home.
