This plaque marks a waypoint on that march from Wyoming to Teaoga, where on August 3 the army camped on the lowlands between here and the river. The relentless expedition burned Iroquois towns and crops, breaking the military power of the Six Nations in the region.

Why it matters

Sullivan's Expedition was a turning point on the Revolution's frontier, opening the way for postwar settlement while dealing a devastating blow to the Haudenosaunee homeland.

Sullivan's March

Tunkhannock, PA · est. 1947

In the summer of 1779, General John Sullivan led thousands of Continental soldiers up the Susquehanna Valley in a scorched-earth campaign ordered by George Washington against the Iroquois Confederacy, allies of the British. On August 3, that army made its third camp above Fort Wyoming here by the river as it pushed north toward Tioga. The march devastated Iroquois towns and croplands, breaking the power of the Six Nations on the New York–Pennsylvania frontier.

Wyoming County

Tunkhannock, PA · est. 1982

Formed in 1842 from Luzerne County, Wyoming County takes its name from an Indigenous word for extensive meadows, describing the broad Wyoming Valley. Tunkhannock, settled in 1790, became the county seat. Decades before the county existed, General Sullivan's army marched through this country in August 1779 during the Revolution's campaign against the Iroquois.
