Apr 30, 1862 Wrote Gen. Wallace, “Advance tomorrow with two Brigades of your Division on the Corinth Road beyond the creek where Gen. McClernand is now encamped, closing up on Gen. Davies’ forces. You will keep to the right of Gen. Buell’s Corps-de-Armée, and avoid mixing in with them.
“As soon as encamped, make roads and bridge the ravines in front and rear of your position to the Corinth road and repair the latter thro’ your limits.
“Take all your Camp and Garrison Equipage. Make immediate requisition for ammunition sufficient for 200 rounds per man including that already on hand, and get it to your camp as soon as possible. Leave Col. M. L. Smith’s Brigade and instruct him that he is to guard the two Purdy roads establishing pickets about where they have been stationed heretofore. All your Cavalry will be left with Col. Smith and one Battery.”
