Wish I had a direct answer for you, but I can only offer some geographic clues that may, or may not, be of some help. Of course, you will want to pull up one of those Google maps to get the lay of the land around Corinth.

I retrieved much of this information from the compiled service records available through subscription to "Footnote."

4/18 Camp Rives–Rienzi, Ms-HQ 1st bgde 1st Div Army of The West-Gen Henry Little writes to Col Jordan that in compliance with the General's wishes, he and Major Peters & Mr. Williams, scouted south & west of here for a place suitable for camping 25,000 men.
About 5 miles from here by RR, and to the right of it. I found a considerable extent of country forming a low ridge, well ……ed[?] and with spring branches convenient, which I am informed never fail. I think that at least 25,000 men could be camped here, and no camp further than 2-300 yards from water.
I also examined the country around Booneville, some 3 miles further south & on the east side of the road, quite a large body of troops could be camped, should there not be space enough at the other.
I am informed that south and west of the road in a circuitry of 10-15 miles, the country is well supplied with forage.
The troops with their baggage can be loaded from the railroad cars within ½ mile of Booneville or the first mention place.
I also rode about a series of ridges covered with pine timber about 2 miles east of this station & on the other side of Tuscumbia Creek. There is good water at the base of these ridges and they would be a healthy site for our encampment, but there is no forage in the vicinity.
…..I herewith enclose a map of the country we went over hastily drawn by Mr. Williams.
H Little, acting B Gen
PS: Major Peters will explain the accompanying map
