Would you post that available record?
Here is the relevant correspondence regarding the plan, if that is what you were looking for:
*****As noted previously, Grant sent the following message to Halleck at 8:00 A.M. on September 16th:
"For ten days or more the enemy have been hovering in our front in reported large force. I have watched their moves closely until I could concentrate my forces. All are now in good shape. Hurlbut's division has come from Memphis to Bolivar and about 6,000 troops from Bolivar brought here. General Orice is southeast from us, near Bay Springs, moving northeast. It is reported that Van Dorn and Breckinridge are to join and attack. Form the best information they cannot reach here under four days. My view is they are covering a move to get General Price into East Tennessee.
If I can I will attack Price before he crosses Bear Creek. If he can be beaten there, it will prevent either the design to go north or to unite forces and attack here."
-17 OR 2:220
Of course, the results of Mower's reconnaissance were not known to Grant yet at the time in which this message was sent.
Rosecrans to Grant on the 17th (not timestamped):
"Hamilton has sent out Mizner with a regiment of infantry and all our cavalry, under Mizner, toward Barnett's, on the Jacinto and Iuka road.
The only thing we can do to prevent Price passing through the defiles of Bear Creek east is to push that division on him and follow it with all of Stanley's force while Ross makes a strong demonstration on his front. This is safe for a day or two if we can keep spies from running to Breckinridge and Van Dorn and Price and you can hold your hand against them. I can pursue with my entire force, which, including Du Bois and Danville, will be about 13,000 men of all arms."
-17 OR 2: 222
Also on September 17th Rosecrans, concerned that they may have already missed their opportunity, wrote the following to Grant:
"Mizner's dispatch just in reports that the cannonading of our reconnoitering party ceased at 4.40 last evening, and that about 8 o'clock last evening a very large fire was seen in the direction of Iuka; the distance is 20 miles. Mizner has gone to feel of them since 4 a.m.
My suspicions are that some houses and stores have been burned in Iuka, the place abandoned, and that Price has crossed the defiles of Bear Creek, and will pass the Tennessee before it rises- at the Shoals, if possible; if not, will proceed at once to above Decatur, near Whitesburg."
-17 OR 2: 222-223
After this message had been sent, Rosecrans messaged from Jacinto later on the 17th (not timestamped) stating that Hamilton was sure that Price was still at Iuka.
17 OR 2: 223
He then forwarded the message from Hamilton to Grant at 9:30 P.M.
-17 OR 2: 224
In yet another message, sent on the 17th, Rosecrans expressed his concern regarding a move from Price, stating that had he not been pursued via their reconnoitering force, he would have probably left Iuka destined for the Tennessee Valley.
-17 OR 2: 223-224
In another message to Grant on the 17th (also not timestamped), probably sent after the above message, but certainly after hearing from Hamilton, returned to the concern expressed above, albeit expressing his hope that Grant was covering against a move directly towards Eastport on his front, stating:
"As Price is an old woodpecker it would be well to have a watch set to see if he might not take a course down the Tennessee, toward Eastport, in hopes to find the means of crossing. Have you any lookout toward Hamburg Landing?
-17 OR 2: 224
Of course, as noted above, it was imperative to prevent a move across Bear Creek to the east for the same reason.
Finally, from the Reports section of the
Official Records, as it was reprinted in Grant's first report of the operation dated September 20th. The original copy is not contained in the correspondence, as is the case with many messages and orders, of course.
It was also not timestamped and is dated September 18th from Rosecrans to Grant. It read:
"One of my spies, in from Reardon's, on the Bay Springs Road, tells of a continuous movement since last Friday of forces eastward. They say Van Dorn is to defend Vicksburg, Breckinridge to make his way to Kentucky, and Price to attack Iuka or to go to Tennessee. If Price's forces are at Iuka the plan I propose is to move up as close as we can to-night and conceal our movements; Ord to advance from Burnsville, commence the attack, and draw their attention that way, while I move in on the Jacinto and Fulton roads,
massing heavily on the Fulton road, and crushing in their left and cutting off their retreat eastward. I propose to leave in ten minutes for Jacinto, from whence I will dispatch you, by line of vedettes, to Burnsville. Will await a few minutes to hear from you before I start. What news from Burnsville?"
-17 OR 1: 66
As can be seen, the Fulton road was just
one way out. It was just
one way out. Rosecrans and Grant has been in communication regarding the situation quite steadily and continuously, to that point.*****
