Ross Hall was a historic colonial farmhouse located on River Road in Piscataway, New Jersey.

In early July 1778, it was the headquarters for General George Washington when he ordered a feu de joie for the second anniversary of the signing of the Declaration of Independence.

[1][2] The other daughter of Morris married Anthony White, who built the nearby Buccleuch Mansion, across the Raritan River, c. 1739.

After the battle, General George Washington and the Continental Army marched north to the Raritan River by New Brunswick for cool, fresh water.

[17][18][19] From his headquarters, Washington ordered a celebration with a feu de joie for the second anniversary of the signing of the Declaration of Independence:[18] Tomorrow, the Anniversary of the Declaration of Independence will be celebrated by the firing thirteen Pieces of Cannon and a feu de joie of the whole line; the Army will be formed on the Brunswick side of the Rariton at five o'Clock in the afternoon on the ground pointed out by the Quarter Master General.

"[21] A gentleman at camp reported on this celebration: My situation being high and at a convenient distance in front, afforded me a complete view of the whole, and presented by far the grandest sight I ever beheld.

The running fire of musketry is grand of itself, but the cannon throwing out their columns of smoke, and adding their sounds at proper distances, made it magnificent beyond description.

An interior, parlor wall of Ross Hall has been preserved and will be displayed in an educational wing at the nearby Metlar-Bodine House Museum.
