Colonel Crook, commanding brigade in Greenbrier County, has just returned from a successful dash upon the Central Railroad, 10 miles beyond Covington, at Jackson’s River Depot. Dispatches were discovered at the telegraph office in Covington from the provost-marshal of Alleghany County, asking General Jackson, at Staunton, for two or three regiments, and stating that he was efideavoring to raise the mnilitia of Greenbrier and Monroe. Answers were also found promising re-enforcements from Jackson by way of Staunton and from Floyd by way of Sweet.Springs. To prevent any immediate advance from Staunton Colonel Crook proceeded from Covington, destroyed the railroad bridge thence to Lewisburg, bringing with him the notorious Captain Sprigg and another guerrilla, captured after firing upon our troops. General Heth is reported to have effected a junction with General Floyd, and to be near Dublin, on the Tennessee Railroad. J. C. FREMONT, Major-General. Hon. E. M. Stanton, Secretary of War.
