The French and American armies marched through Philadelphia from September 2 to 4, where the American soldiers announced they would not leave Maryland until they received one month's pay in coin, rather than in the worthless Continental paper currency. General Rochambeau generously loaned Washington half of his supply of gold Spanish coins. This would be the last time the men would be paid. This strengthened French and American relations. On September 5, Washington learned of the arrival of de Grasse's fleet off the Virginia Capes. De Grasse debarked his French troops to join Lafayette, and then sent his empty transports to pick up the American troops. Washington made a visit to his home, Mount Vernon, on his way to Yorktown.
