At or near this point on July 8, 1755, Major General Edward Braddock and his army camped during his military expedition against Fort Duquesne. Here also George Washington, who had taken ill at Bear Camp, now Oakton Maryland, on June 19, 1755, rejoined the army. About one mile distant, near the mouth of Crooked Run, Braddock crossed the Monongahela River on the morning of July 9, 1755, and in the evening retreated by the same route.
