On September 13, 1779, at this site, Lieut. Thomas Boyd's scouting party of Gen. Sullivan's army was overwhelmed after a desperate and heroic struggle in an ambuscade by British and Indians under Butler and Brant. Boyd and Sergt. Michael Parker were captured and afterward tortured and killed. Also killed here were Oneida Indian Lt. Han Yost, Thaosagwat, who was acting as a guide for Boyd's scouting party, Sergt. Nicholas Hungerman, Privates Benjamin Curtin, William Faughey, James McElroy, William Harvey, John Putnam, John Conrey, John Miller, seven others whose names are unknown, and Benjamin Wheeler. The name Hanyerry, identified there as a loyal Oneida chief, was mistakenly placed on the monument instead of Han Yost's brother's correct name.
