MAJ. GEN. J. A. MCCLERNAND
COMD. G EXPEDITION ON VICKSBURG,
Since Gen. Sherman left here I have been unable to learn anything official from the expedition which you now command. 1 Your wants and requirements all have to be guessed at. I am prepared to reinforce you immediately with one Division from my old command one brigade from Gen. Curtis' and one brigade coming from Gen. Wright's Dept. I can also further reinforce you with one more Division from my old command besides sending all other troops that come to me from elswhere.
This expedition must not fail. If there is force enough within the limits of my controll to secure a certain victory at Vicksburg they will be sent there. But I want to be advised of what has been done; what there is to contend against, and an estimate of of what is required. —I take it for granted that Ordnance stores, rations &c. will be required for the command now with you in addition to what they now have and to a full supply for all reinforcements.
I would like to have a full report immediately for my guidance as to what is to be done.
Troops are assembling here, and all transports coming into port or being detained. If you have any not required for the troops with you release them to come here. 2
I am Gen. very respectfully
your obt. svt.
