Rumored removal of Rosecrans to Virginia.
--The Chattanooga Rebel, of the 6th, is informed by a brother of Lieut Col. Wm. Ewing, who has just returned from Middle Tennessee, that Rosecrans no longer commands the Army of Tennessee, and that he has gone to Virginia. It is not known who will be his successor, but it is guaranteed that Grant will be immediately called to that position. The correspondent of the Memphis Appeal mentions the transfer of Rosecrans from Tennessee to Virginia as a rumor.
