dividing colonial and Native American lands was disputed. The colonists claimed this was Pine Creek, the Iroquois and other tribes Lycoming Creek. The area between Pine and Lycoming creeks was disputed territory. The illegal settlers there were part of the "Fair Play Men" system of self-government, with their own Declaration of Independence from Britain on July 4, 1776. In the American Revolutionary War, settlements throughout the Susquehanna valley were attacked by Loyalists and Native Americans allied with the British. After the Wyoming Valley battle and massacre in the summer of 1778 (near what is now Wilkes-Barre) and smaller local attacks, the "Big Runaway" occurred throughout the West Branch Susquehanna valley. Settlers fled feared and actual attacks by the British and their allies. Homes and fields were abandoned, with livestock driven along and a few possessions floated on rafts on the river east to Muncy, then further south to Sunbury. The abandoned property was burnt by the attackers. Some settlers soon returned, only to flee again in the summer of 1779 in the "Little Runaway". The Sullivan Expedition helped stabilize the area and encouraged resettlement, which continued after the war. In 1790, Timothy Matlack, Samuel Maclay and John Adlum were commissioned by the Supreme Executive Council of the Commonwealth of Pennsylvania to survey the headwaters of the Susquehanna and explore a route for a passageway to connect the West Branch with the waters of the Allegheny River. The Fair Play Men were illegal settlers (squatters) who established their own system of self-rule from 1773 to 1785 in the West Branch Susquehanna River Valley of Pennsylvania. Because they settled in territory claimed by Native Americans, they had no recourse to the Pennsylvania colonial government. Accordingly, they established what was known as the Fair Play System, with three elected commissioners who ruled on land claims and other issues for the group. In a remarkable coincidence, the Fair Play Men made their own declaration of independence from Britain on July 4, 1776, beneath the "Tiadaghton Elm" on the banks of Pine Creek. Fort Antes was a stockade surrounding the home of Colonel John Henry Antes, built circa 1778 in Revolutionary Pennsylvania in the United States. The fort was built under the direction of Colonel Antes, who was a member of the Pennsylvania militia. It was on the east side of Antes Creek, overlooking and on the left bank of the West Branch Susquehanna River
