LOUISVILLE, September 19. — At the surrender of Mumfordsville, on Wednesday morning, the rebels took about 45 prisoners, who are reported to have been subsequently paroled, comprising the 6th, 67th and 39th Indiana; one company of the 1st Wisconsin; one company of the Louisville provost guards, 70 recruits for the 33d Kentucky, the 4th Ohio battery of six guns, with four other guns in position.

The loss at Mumfordsville, previously stated, was in Sunday's fight.

There were two or three hours of skirmishing on Tuesday between sharpshooters of both parties.

The rebels did not attack us in force in Sunday's fight.

Gen. Chalmers made an attack on our forces with eleven regiments. On Tuesday night Buckner's division was added to this force. The rebel firing on Tuesday was a rebel feint, to enable them to secure the north bank of the river. In that affair we lost one killed and four or five wounded; eleven of the enemy were killed.

Very many reports are circulating from down the river, the transmission whereof is forbidden by the military authorities, who now entertain the hope and belief that the preparations now actively consummating will not only insure the safety of Louisville, but speedily clear Kentucky of her rebel invaders.

HARRISBURG, September 19. — A gentleman from Chambersburg this evening, says all the troops stationed there have been sent to Hagerstown and Boonsboro. A company from Philadelphia refused to go over the line. General Reynolds said they might go home and be damned, and disgrace would forever rest on their shoulders. After the general's reprimand, they finally went over the borders.

Governor Curtin is still at Hagerstown.

A feeling of perfect security is now felt in official circles.

Quite a number of wounded have arrived here and at other points on the Cumberland Valley Road.

The news of McClellan's great victory, as received to-day, was welcomed with great rejoicing.

The troops here are urging to be sent forward, that they may yet assist in the great work.

Travel to Chambersburg and Hagerstown was returned to-day, and the telegraph is now open to Boonsboro.
