After returning to the Great Meadows in northwestern Virginia, and what is now Fayette County, Pennsylvania, George Washington decided it prudent to reinforce his position.
The crude palisade they erected was built more to defend supplies in the fort's storehouse from Washington's own men, whom he described as "loose and idle", than as a planned defense against a hostile enemy.
Washington spent the remainder of June 1754 extending the wilderness road further west and down the western slopes of the Allegheny range into the valley of the Monongahela River.
The area eventually became the site of Nemacolin Castle and Brownsville, Pennsylvania—an important western jumping-off point for travelers crossing the Alleghenies in the late 18th and early 19th centuries.
He preferred this to following the ridge-hopping, high-altitude path traversed by the western part of the route that was later chosen for Braddock's Road.
It jogged to the north near the fort and passed over another notch near Confluence, Pennsylvania, into the valley and drainage basin of the Youghiogheny River.
Washington did not speak French, and stated later that if he had known that he was confessing to the "assassination" of Joseph Coulon de Jumonville, he would not have signed the surrender document.
On a hillside adjacent to the battlefield and within the boundaries of the park is Mount Washington Tavern, a classic example of the many inns once lining the National Road, the United States' first federally funded highway.
It was operated by his family until the railroad construction boom caused the National Road to decline in popularity, rendering the inn unprofitable.
In a separate unit of the park, lying about one mile (1.6 km) northwest of the battlefield, is the grave of General Edward Braddock.
