Granger and Sheridan reached Louisville before Buell got there, and on the night of their arrival Sheridan with his command threw up works around the railroad station for the defence of troops as they came from the front.
Advance of Van Dorn and price—price enters Iuka—battle of Iuka.
At this time, September 4th, I had two divisions of the Army of the Mississippi stationed at Corinth, Rienzi, Jacinto and Danville. There were at Corinth also Davies’ division and two brigades of McArthur’s, besides cavalry and artillery. This force constituted my left wing, of which Rosecrans was in command. General Ord commanded the centre, from Bethel to Humboldt on the Mobile and Ohio railroad and from Jackson to Bolivar where the Mississippi Central is crossed by the Hatchie River. General Sherman commanded on the right at Memphis with two of his brigades back at Brownsville, at the crossing of the Hatchie River by the Memphis and Ohio railroad. This made the most convenient arrangement I could devise for concentrating all my spare forces upon any threatened point. All the troops of the command were within telegraphic communication of each other, except those under Sherman. By bringing a portion of his command to Brownsville, from which point there was a railroad and telegraph back to Memphis, communication could be had with that part of my command within a few hours by the use of couriers. In case it became necessary to reinforce Corinth, by this arrangement all the troops at Bolivar, except a small guard, could be sent by rail by the way of Jackson in less than twenty-four hours; while the troops from Brownsville could march up to Bolivar to take their place.
On the 7th of September I learned of the advance of Van Dorn and Price, apparently upon Corinth. One division was brought from Memphis to Bolivar to meet any emergency that might arise from this move of the enemy. I was much concerned because my first duty, after holding the territory acquired within my command, was to prevent further reinforcing of Bragg in Middle Tennessee. Already the Army of Northern Virginia had defeated the army under General Pope and was invading Maryland. In the Centre General Buell was on his way to Louisville and Bragg marching parallel to him with a large Confederate force for the Ohio River.
I had been constantly called upon to reinforce Buell until at this time my entire force numbered less than 50,000 men, of all arms. This included everything from Cairo south within my jurisdiction. If I too should be driven back, the Ohio River would become the line dividing the belligerents west of the Alleghanies, while at the East the line was already farther north than when hostilities commenced at the opening of the war. It is true Nashville was never given
