Late from Louisiana--Banks, the commissary.
Gen. Banks, the old commissary in Virginia of the lamented Stonewall Jackson, appears to be doing good service in his Louisiana Department to Gen. Kirby Smith. It appears that the advance of Banks's army from Alexdria met with no obstruction in getting across the country to the Mississippi river, and were then crossed to Bayon Sara on gunboats and transports. The remnant, consisting of a large Yankee force and four thousand negroes, were in the rear with about fifty wagons loaded with supplies. The Natchez (Miss.) Courier says:‘ We are informed by a soldier, who was in the neighborhood of Cheneyville, in the lower part of Rapids parish, that quite a skirmish occurred there last week with this portion of Gen. Banks's force. He was a witness to one portion of the fight. He says Gen. Mouton, with 1500 or 2000 cavalry, made a spirited attack upon the force accompanying the train, and, after several charges, routed the Yankees, broke up their organization, took a large number of them prisoners, and captured the whole train of wagons, horses, mules, and provisions. Gen. Monton's cavalry also secured the whole four thousand negroes that the enemy had taken from the parishes through which the army had passed.
’ When our informant left the vicinity of Cheneyville General Mouton's cavalry were hourly bringing in prisoners, who had been routed and scattered by the fight. Gen. Banks proved an excellent commissary to the Confederates in the Shenandoah Valley, and he is now sustaining his good reputation in the Gulf Department. This is the second heavy train Gen. Mouton's cavalry has captured from Banks this spring.
