Tuesday the five and twentieth of August, 1657. At the Council at Whitehall.  
HIs Highness and the Council, calling to mind the memorable Mercies which the Lord was pleased to vouchsafe to this Nation of England, in the admirable successes and Victories given to their Forces, on the third day of September, in the year 1650. at Dunbar, and on the same day in the year 1651. at Worcester, and being desirous that such eminent salvations wrought by the Lord, should not be forgotten, but continued in thankful remembrance, Have thought fit to appoint and set apart Thursday the third day of September next, to be a day of Public and Solemn Thanksgiving to the Lord, in the remembrance of the Mercies aforesaid, to be kept and observed in the Cities of London and Westminster, and all places within the late Lines of Communication, and Weekly Bills of Mortality, and all other places where the notice hereof shall come, not doubting but the Ministers and such as fear the Lord in this Nation, will with all readiness join in a Duty to which God hath engaged them by such signal and redoubled providences.  
Henry Scobell, Clerk of the Council.
