Braddock Expedition Supply Depot

In seventeen fifty-five, this site served as a key supply depot for General Edward Braddock's ill-fated campaign against the French at Fort Duquesne. Supplies are said to have been stored in the strong stone house belonging to Edward Shippen, known locally as the house at the Back Run. James Burd, Shippen's son-in-law, cut a road westward to carry those provisions toward the frontier.

Braddock's army, marching through dense Pennsylvania woodland, was ambushed and routed near present-day Pittsburgh in July seventeen fifty-five. Braddock himself was mortally wounded. Remaining supplies are said to have been distributed to settlers who had suffered Indian raids in the wake of the disaster, as the frontier collapsed into violence.
