Colonel John Butler recruited a regiment of Loyalists, Seneca chiefs Sayenqueraghta and Cornplanter recruited primarily Seneca warriors, and Joseph Brant recruited mostly Mohawks, for a guerrilla war against the American frontier settlers. By April 1778, the Senecas were raiding settlements along the Allegheny and Susquehanna rivers, and the three groups met at the Indian village of Tioga, New York, in early June. Butler and the Senecas decided to attack the Wyoming Valley, while Brant and the Mohawks targeted settlements farther north.
