Monterey May 6th 1862
If the regiment you spoke of this morning are already at Pittsburg Landing, leave them there. If the last have not gone however you need not send it as Genl. Halleck only contemplated leaving three regiments from the Reserve back.
The regiments stationed near Genl. Halleck's old Hd Quarters was all the support of Col. Woods. Capt Hawkins is Telegraphed to come up and make the necessary arrangements for fresh beef.
Copy, Register of Letters, McClernand Papers, IHi. On May 6, 1862, Maj. Gen John A. McClernand endorsed this letter. "Having brought the subject of the foregoing communication Genl. Grant with the request that he would bring it to the attention of Genl. Halleck he was pleased to do so, and with the result here shown. If the regiment ordered by me to be detached for service at the Purdy Bridge, near your late camp has been sent back, and the one called for by Col Wood's has not; then return the latter, and vice verse."
