Fight in East Tennessee.
We have a report that a considerable battle took place at Big Creek Gap, in East Tennessee, on Friday last, between the forces of Gen. Buckner and the Federal General, Burnside, in which the enemy are said to have been repulsed twice with heavy loss. Burnside then commenced a flank movement and Gen. Buckner fell back to cover Knoxville. The point at which the latter took up position was Clinton, within 15 miles of the East Tennessee and Georgia railroad. Other reports state that the enemy had possession of the railroad at Lenoir, and that they were advancing in another body; and after having been defeated near Knoxville were retreating eastward. The telegraph wires between Bristol and Knoxville had been cut — supposed by the Union men of East Tennessee.
