Gen. Wheeler's operations.
--The Marietta Rebel, of Saturday evening last, contains a special telegram giving a connected account of Gen. Wheeler's operations in Middle Tennessee. He crossed the river at Cotton Port, above Chattanooga, on the 30th day of September, under a heavy fire, but routed the enemy and entered the Sequatchie Valley. He met a wagon train, one thousand in number, well guarded, and attacked them. A hand fight ensued, but he captured everything, including several thousand prisoners. He killed the mules and burnt the wagons and stores. He next sent Gen. Wharton to McMinnville to invest the place, and then followed with his entire command. He captured the garrison, including two regiments of Yankee infantry and thirty days rations for Rosecrans's army, which he destroyed.--He paroled all the prisoners, and exchanged his worn-down horses for good ones. He next dashed on and destroyed the bridges over Stone and Duck rivers, while Wharton threatened Murfreesboro'. Wharton then joined Wheeler at Shelbyville. The enemy were here reinforced and fought and drove Gen. Wheeler back. He retreated across the Tennessee near Courtland, Ala. The Confederate loss was heavy, but the whole affair was a brilliant exploit. Roddy is reported to have blown up the tunnel at Cowans.
