We learn by flag of truce, from the rebels at Kinston, that their (the rebels) loss is between eight and nine hundred, and that the two South Carolina regiments that charged Morrison's battery, lost in that charge about three hundred and fifty men; their color bearer was shot three times.


BRILLIANT CONDUCT OF THE UNION TROOPS.

Kinston, N. C., Dec. 15, 1862.

An important movement has long been on foot looking towards the capture of Goldsboro and Weldon, and the severance of one rebel railroad line of communication connecting the cotton states with the capital of the so-called confederacy; Preparations have for some time been carried to enable the force which was to engage in the attempt to push it to a successful issue. The time has now come when the object and the means of execution of this movement may be safely revealed. The object of the expedition was to capture Kinston, and then to take Goldsboro, thereby cutting the Wilmington and Weldon railroad, which would isolate Wilmington and effectually cut off its supplies and reinforcements. That, I believe, was the object of the expedition. The first portion of the work has been accomplished—the capture of Kinston; and the other portion is in a fair way of being carried successfully out to the letter.

The forces under General Foster left New Berne on Thursday, the 11th, and moved up the Trent road, along the Trent River, about ten miles, when the division halted for the night. On Friday the march was resumed at sunrise, the Ninth New Jersey having the extreme advance, followed by Wessell's brigade, one of General Peck's brigade, recently sent from Suffolk, with Company B, Third New York Artillery, Captain Morrison. Then followed the brigade of Acting Brigadier-General Amory consisting of four Massachusetts regiments.

Acting Brigadier-General Lee's brigade of Massachusetts regiments came next, Colonel Stevenson's brigade, also of Massachusetts regiments, brought up the rear with four regiments. Acting Brigadier-General Ledlie, of the Third New York Artillery, had command of the artillery, consisting of the Third New York Artillery and Belger's battery, First Rhode Island Artillery. Colonel Mix's Third New York Cavalry, Lieutenant-Colonel Mix in command, were employed as scouts on the advance and on the sides of the line of march, and as provost-guards to protect houses along the road.

On Friday night the column halted within eleven miles of Kinston, and encamped in line of battle, no fires being allowed and all unusual noises prohibited. The troops did not get into camp until 9 o'clock. Skirmishing continued all day between cavalry of the rebels and Mix's cavalry, in which we lost two men prisoners and one wounded. We captured fifteen or sixteen of the rebel cavalry, and killed and wounded several.

On Saturday morning at 7 o'clock the line of march was resumed towards Kinston at a slow pace, as the enemy were beginning to appear in some force in front, to a point where the Whitehall, and main Kinston roads unite, about seven miles from Kinston. This point was reached at about 11 o'clock on Saturday morning, and then it was that it was expected that the rebels would offer battle, as it was a strong position. Our troops were formed in line of battle in an open field on the left of the road which ran to Whitehall, in front of a wood, which it was supposed covered the enemy's main force. A small creek ran across the road 500 yards to the right and in front of our line of battle, over which was a bridge, which the rebels had destroyed, and out of the debris of which they had erected a breast-work and planted two six-pounders, rifled, sweeping the road. Morrison's battery was put forward to the right of the road, and taking a position on a small hill 250 yards from the rebel battery, opened fire. The enemy hotly replied with grape and canister, sweeping the road, but doing no damage. Morrison continued to shell the battery and the woods on either side for nearly an hour, when the enemy began to retire. Just as the enemy were about retiring, the Ninth New Jersey were deployed as skirmishers to the left of the road, and advancing under fire, they crossed the creek on a mill dam, flanked the rebel battery, and, taking it by storm, captured a rifled six-pounder and several prisoners. The rebels retreated hastily and succeeded in saving the other six-pounder, but left six killed and wounded. Three hours were consumed in the reconstruction of the bridge. When completed the infantry and artillery crossed and marched towards Kinston, about three and a half miles, and halted for the night, in line of battle, with strong pickets out. The enemy made but feeble resistance to the advance of our forces, Mix's cavalry driving them like chaff before them. The night passed quietly, a little affair between pickets, without result, breaking the monotony of the night.
