Strategic Narrative Overview
Four Continental Army brigades under General John Sullivan, coordinating with forces under General James Clinton, advanced through present-day central New York from June to October 1779. The army systematically destroyed Iroquois towns, burned crops, and demolished food stores across the territory of the Seneca, Cayuga, Onondaga, and Mohawk nations. Resistance was met at the Battle of Newtown in August 1779, where Sullivan's forces dispersed a combined Iroquois and Loyalist force, after which destruction of villages continued largely unopposed.
01 / The Origins
In 1778, British-allied Iroquois nations and Loyalist raiders devastated American frontier settlements at Wyoming Valley, Pennsylvania, and Cherry Valley, New York, killing settlers and burning farms. In response, General George Washington ordered a large-scale punitive campaign with the explicit aim of the total destruction and devastation of Iroquois settlements, intending to permanently remove the Iroquois threat to the American frontier and neutralize British influence among the Haudenosaunee Confederacy.
03 / The Outcome
The campaign succeeded in its stated objectives, forcing more than 5,000 Iroquois to abandon their homelands and seek refuge at Fort Niagara under British protection. The region was effectively depopulated, opening central New York to post-Revolutionary American settlement. The Iroquois Confederacy never recovered its former strength in the region. Debate persists among scholars over whether the campaign constitutes genocide, though the term remains contested.
