[Southern Association Dispatches]
from the West--Federates advancing — a battle imminent near Murfreesboro — Morgan Captures Glasgow. Murfreesboro', Dec. 28
--The enemy is still advancing slowly from several points, and his force is estimated at 33,000.
He left a garrison of 10,000 at Nashville on the 1st.
His columns, 8,000 strong, are now at Salem, five miles distant. A general engagement cannot be avoided longer than to-morrow, as the opposing lines of battle are in close proximity this evening in that vicinity.
General Morgan captured Glasgow, Ky, and the Federal garrison, on Christmas day, after which he proceeded to Gallatin and again blew up the railroad tunnel, and left the railroad entirely useless to the enemy.
