One of the earliest July 4th celebrations on the Banks of the Raritan:
From his headquarters, Washington ordered a celebration with a
feu de joie for the second anniversary of the signing of the
Declaration of Independence:
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. The Soldiers are to adorn their Hats with Green-Boughs and to make the best appearance possible. The disposition will be given in the orders of tomorrow. Double allowance of rum will be served out.
— George Washington, July 3, 1778
