Accordingly, all previous orders given during the day for movements on the 13th were annulled by new ones. McPherson was ordered at daylight to move on Clinton, ten miles from Jackson; Sherman was notified of my determination to capture Jackson and work from there westward. He was ordered to start at four in the morning and march to Raymond. McClernand was ordered to march with three divisions by Dillon's to Raymond. One was left to guard the crossing of the Big Black.

On the 10th I had received a letter from Banks, on the Red River, asking reinforcements. Porter had gone to his assistance with a part of his fleet on the 3d, and I now wrote to him describing my position and declining to send any troops. I looked upon side movements as long as the enemy held Port Hudson and Vicksburg as a waste of time and material.

General Joseph E. Johnston arrived at Jackson in the night of the 13th from Tennessee, and immediately assumed command of all the Confederate troops in Mississippi. I knew he was expecting reinforcements from the south and east. On the 6th I had written to General Halleck: "Information from the other side leaves me to believe the enemy are bringing forces from Tullahoma."
