Forbes Expedition

The site is now located in Pittsburgh's Golden Triangle in the downtown area (Or The Point) Forbes commanded about 6,000 men, including a contingent of Virginians led by George Washington.

Working for most of the summer on the construction of the road and on periodic fortified supply depots, the expedition did not come within striking distance of Fort Duquesne until September 1758.

The Treaty of Easton concluded on October 26, 1758, caused the remnants[b] of the Lenape (Delaware), Mingo, and Shawnee tribes in the Ohio Valley to abandon the French and set up the conditions that ultimately forced them to move westward once again.

Three units of scouts led by Captain Hugh Waddell entered the smoking remnants of the fort under the orders of Colonel George Washington on November 24.

The collapse of Indian support and subsequent withdrawal of the French from the Ohio Country helped contribute to the "year of wonders" the string of British "miraculous" victories also known by the Latin phrase Annus Mirabilis.
