Major-General Forney
Vicksburg
 
   Send a train of cars here {on the Southern (of Mississippi) RR}. The enemy's artillery has opened at the intrenchments at Big Black. Should they succeed in crossing at Bridgeport, it will be necessary to draw troops from Snyder's Mill. Subsistence must now be gotten into Vicksburg from that quarter as soon as possible, in the possible event of the evacuation of Snyder's. Ammunition must be destroyed, guns double charged and forced, unless they can be removed, and everything destroyed that cannot be removed.
J. C. Pemberton
