The Pictorial Field-Book of the Revolution…
“ A few weeks subsequently, while taking a circuit alone through the woods near the head waters of the Susquehanna, Harper met some Indians, who exchanged salutations with him. He recognized one of them as Peter, an Indian whom he had seen at Oghkwaga, but they did not know him. His great-coat covered his uniform, and he feigning to be a Tory, they told him they were on their way to cut off the Johnstone settlement on the east shore of the Susquehanna, near Unadilla. Colonel Harper hastened back to Harpersfield, collected fifteen stout and brave men, and with them gave chase to the marauders. ”
