General Rosecrans had previously had his headquarters at Iuka, where his command was spread out along the Memphis and Charleston railroad eastward. While there he had a most excellent map prepared showing all the roads and streams in the surrounding country. He was also personally familiar with the ground, so that I deferred very much to him in my plans for the approach. We had cars enough to transport all of General Ord's command, which was to go by rail to Burnsville, a point on the road about seven miles west of Iuka. From there his troops were to march by the north side of the railroad and attack Price from the north-west, while Rosecrans was to move eastward from his position south of Corinth by way of the Jacinto road. A small force was to hold the Jacinto road where it turns to the north-east, while the main force moved on the Fulton road which comes into Iuka further east. This plan was suggested by Rosecrans.

Bear Creek, a few miles to the east of the Fulton road, is a formidable obstacle to the movement of troops in the absence of bridges, all of which, in September, 1862, had been destroyed in that vicinity. The Tennessee, to the north-east, not many miles away, was also a formidable obstacle for an army followed by a pursuing force. Ord was on the north-west, and even if a rebel movement had been possible in that direction it could have brought only temporary relief, for it would have carried Price's army to the rear of the National forces and isolated it from all support. It looked to me that, if Price would remain in Iuka until we could get there, his annihilation was inevitable.
