On May 28, 1752, the British held a council at Logstown with representatives of the Six Nations, and the Lenape and Shawnee who had been tributary to them. Colonel Joshua Fry and two other commissioners represented the colony of Virginia, and Christopher Gist represented the Ohio Company. The Iroquois half-King or sachem, Tanacharison, declared that his people did not consider that the 1744 Anglo-Iroquois Treaty of Lancaster had ceded the colonists any land beyond the Allegheny Mountains, but he promised the Iroquois would not molest any British settlements southeast of the Ohio River. He also formally requested that a British fort be built at the mouth of the Monongahela River, the site of present-day Pittsburgh. This fort, Fort Prince George, was still in construction in January 1754 when it was razed by a much larger French force, which then built Fort Duquesne in the same spot.
