On July 3, 1778, Loyalist commander Colonel Butler led his Rangers accompanied by a force of Senecas and Cayugas (led by Sayenqueraghta) in an attack on Pennsylvania's Wyoming Valley (a rebel granary and settlement along the Susquehanna River near Wilkes-Barre), practically annihilating 360 armed Patriot defenders lured out of their defenses at Forty Fort.
