For instance, if you look at Grant's first report, dated September 20th, you will see that he reported to the government, with no disapprobation whatever, that Rosecrans force "attacked Price, south of this village, about two hours before dark yesterday."
-17 OR 1: 64
Or just read the correspondence from the 19th which can be readily seen at 17 OR 1: 69 and elsewhere. Or read
all of the available reports. It is clear that the Army of the Mississippi was pushing on to Iuka on the 19th.
Being that we know that the conception of the plan factored in the ability of the Army of the West to pull back across Bear Creek as a fundamental consideration (one only need to read the correspondence on that), especially as Rosecrans detailed the plan to Grant, regardless of whether that assessment was accurate or not, the question then becomes how do you operate as the situation transpired on the 19th? What was the most likely way to accomplish those objectives by the time in which the Army of the Mississippi reached Barnett's Crossroads? That is really the central relevant question as far as the plan as it was conceived was concerned, unless, of course, that assessment was inaccurate. I would pass that question on to you?
I
do agree with you that there
had been heavy rain over several days leading up the 19th. I would quote S.A. Hurlbut, for instance, from Bolivar, to U.S. Grant on September 18th making the point that the roads in his area had been impacted by the rainfall.
-17 OR 2: 226-227
Now, it is certainly possible that maybe the plan as Rosecrans had conceived it should have been modified on the basis of the recent rains, but we can't controvert how the plan was actually described, nor the fact that it was being described as such the same day on the 17th and 18th in messages to Grant from Rosecrans.
So, again, my question would be what would seem to be the relevant question, which is how best could that be done?
