Dispatches from Generalissimo Lee inform the Secretary that large expeditions are on foot in Alabama, Mississippi, etc., and that Thomas’s army is rapidly advancing upon Virginia from East Tennessee, while no general has yet been designated to command our troops.

Custis says letters still flow in asking authority to raise negro troops.
