MAJOR GENL. MCCLERNAND.
COMMDG EXPEDITION ON VICKSBURG.
Unless absolutely necessary for the object of your expedition you will abstain from all moves not connected with it. I do not approve of your move on the "Post of Arkansas" whilst the other is in abeyance. It will lead to the loss of men without a result. So long as Arkansas cannot reinforce the enemy East of the river we have no present interest in troubling them. It might answer for some of the purposes you suggest but certainly not as a Military movement looking to the accomplishment of the one great result, the capture of Vicksburg.
Unless you are acting under authority not derived from me keep your command where it can soonest be assembled for the renewal of the attack on Vicksburg.
