There were already at that time more or less telling indications that the withdrawal of the rebels from Corinth had been but the first act in a new strategic programme aiming at a complete shifting of the scene of active operations and the resumption of the offensive by them. It gradually became clear that this programme comprised the transfer of the rebel army from middle Mississippi to Chattanooga, and a flanking movement thence against Buell under the leadership of General Bragg, who had superseded Beauregard.
