Heller’s Tavern near Wind Gap marked the end of the first day’s march for Major General John Sullivan’s Continental army after it left Easton on June 18, 1779. The army had spent weeks gathering men, animals, artillery, boats, food, and equipment for an expedition into Haudenosaunee country. At four o’clock the following morning, the troops stirred again and began crossing the mountain through Wind Gap, turning a familiar travel corridor into a military supply route.

Washington ordered the Sullivan–Clinton campaign after devastating frontier warfare, including Loyalist and Haudenosaunee attacks at Wyoming and Cherry Valley. Its stated goal went far beyond defeating an opposing field force. Sullivan was directed to destroy the settlements and food resources of nations allied with Britain, especially the Seneca and Cayuga, so they could no longer support raids. Thousands of Continental soldiers ultimately participated, joined by a column under James Clinton.

The halt at Heller’s Tavern illustrates the expedition’s logistical scale. A large army required camps, water, grazing, firewood, repair work, guards, and carefully sequenced movement through constricted terrain. Packhorses carried supplies where wagons could not pass. Easton’s population and resources had already been strained by the long preparation. Wind Gap posed the next obstacle, and an early departure allowed the column to negotiate the ascent before heat, congestion, and fatigue worsened.

Farther north and west, the campaign fought its principal battle at Newtown and systematically burned towns, houses, cornfields, orchards, and stored food. Many Haudenosaunee residents evacuated before the army arrived, but the destruction drove thousands toward Fort Niagara. Exposure, hunger, and disease followed during the winter. The expedition damaged the ability to support British operations but did not end Indigenous resistance, and retaliatory frontier violence continued.

Modern interpretation must include those consequences. Older markers often present the route as an uncomplicated feat of American arms, while Haudenosaunee communities remember invasion, displacement, and destruction of homelands. Both the frontier attacks that prompted Washington’s order and the campaign’s deliberate devastation belong in the history. The army’s efficient movement through Wind Gap helped make possible a scorched-earth operation whose civilian effects far exceeded casualties in its few set battles.

The marker identifies Heller’s Tavern as a camp and route point, not a battlefield. The tavern supplied a recognizable stopping place at the base of the mountain; the surrounding roads and gap explain why the army passed here. Following the march from this location reveals the connection between ordinary infrastructure and continental violence. A single night’s encampment formed the opening step in one of the Revolution’s largest and most consequential campaigns against Native communities.
