Barboursville, Ky, January 8, 1863

Maj. Gen. Halleck
        Washington, D.C.

         Owing to his want of clothing, particularly shoes in Foster's command, it is impossible to move more than Sixty per cent of his men until they are supplied. Clothing is now on its way, and it is hoped will be in Knoxville within one week from this time. I have directed Foster then to attack and drive Longstreet at least beyond Bull's Gap and Red Bridge. In the meantime I have directed the 9th and 23rd Corps to be pushed on to Moss Creek — the 4th Corps to Strawberry Plains, and the Cavalry to Dandridge to scout and forage south of French Broad, and threaten Longstreet's flank.
