From east Tennessee.
Bristol, Dec. 11.
--General Longstreet is slowly falling back from Morristown, presenting a bold front to the enemy, who, since the sharp skirmish at Morristown, have not pressed him. Our last advices represent him at Watanga river, near Kings port.
As Cumberland Gap is no longer in his rear no apprehensions are felt as to his safety.
All the hospitals along the railroad have been emptied to receive his wounded, numbering about six hundred.
Dalton, Dec. 11.
