Fort Moultrie was evacuated to-night. Previous to the evacuation, the guns were spiked and the carriages destroyed by fire. The troops have all been conveyed to Fort Sumter. Major Anderson states that he evacuated the fort in order to allay time discussion about that post, and at the same time strengthen his own position.--(Doc. 7.) The evacuation of the fort commenced a little after sundown. The men were ordered to hold themselves in readiness, with knapsacks packed, at a moment's notice; but up to the moment of their leaving lad no idea of abandoning tlme post. They were reviewed on parade, and were then ordered to two schooners lying in the vicinity, where they embarked, taking with them all the necessaries, stores, &c., requisite in their evacuation. Several trips were made during the night, and a great part of the provisions and camp furniture were transported under cover of night. The brightness of the moon, however, afforded but slight concealment to their movements, and in one of the trips, Lieutenant Davis in command, a schooner full of soldiers and baggage passed directly under the bow of the guard-boat Nina. The officer who made the statement expressed himself to be ignorant whether the watch on board the Nina discovered the movement or not; at all events, he said, they did not signify any cognizance of the fact.--(Doc. 8.)--Charleston Mercury, Dec. 28;
