WAR DEPARTMENT,

Washington, November 27, 1863-12 m.

Major-General MEADE, Army of the Potomac:

General Grant's operations to-day will probably cut Longstreet's line of communication with Bragg. If Burnside holds his position at Knoxville a few days longer, Longstreet will be obliged to retire up the line of the Virginia and Tennessee Railroad, to rejoin Lee. If the Army of the Potomac does not act soon, it may find Lee re-enforced by Longstreet's army.

H. W. HALLECK,

General-in-Chief.
