December 07, 1863
Reliable information being received that the insurgent force is retreating from east Tennessee under circumstances rendering it probable that the Union forces can not hereafter be dislodged from that important position, and exteeming this to be of high national consequence, I recommend that all loyal people do, on receipt of this information, assemble at their places of worship and render special homage and gratitude to Almighty God for this great advancement of the national cause.
A. LINCOLN.
