Rock Fort Camp, Braddock's tenth camp, began at the woods opposite where the Washington-Braddock Road emerged from Chestnut Ridge Mountain and extended northward beyond the Half King's Rock and Washington's Spring. Braddock camped here on June 28, 1755, before moving on to his next camp at Gist's plantation. De Villiers, who commanded the French army at Fort Necessity on July 3, 1754, camped here on July 4, 1754, en route to Fort Duquesne. Washington's first battlefield lies two miles to the north.
