Washington also had numerous visitors while at the Dey Mansion, those of which include the Marquis de Lafayette, General Anthony Wayne, Major General Lord Stirling, Benedict Arnold, General William Howe and the Marquis de Chastellux.


During Washington's time away from the Dey Mansion Major, General Benedict Arnold's treason became evident and his accomplice Major John Andre was hanged in Tappan, New York on October 2.
