After the unsuccessful assault of the 22d the work of the regular siege began. Sherman occupied the right starting from the river above Vicksburg, McPherson the centre (McArthur's division now with him) and McClernand the left, holding the road south to Warrenton. Lauman's division arrived at this time and was placed on the extreme left of the line. In the interval between the assaults of the 19th and 22d, roads had been completed from the Yazoo River and Chickasaw Bayou, around the rear of the army, to enable us to bring up supplies of food and ammunition; ground had been selected and cleared on which the troops were to be encamped, and tents and cooking utensils were brought up. The troops had been without these from the time of crossing the Mississippi up to this time. All was now ready for the pick and spade. Prentiss and Hurlbut were ordered to send forward every man that could be spared. Cavalry especially was wanted to watch the fords along the Big Black, and to observe Johnston. I knew that Johnston was receiving reinforcements from Bragg, who was confronting Rosecrans in Tennessee. Vicksburg was so important to the enemy that I believed he would make the most strenuous efforts to raise the siege, even at the risk of losing ground elsewhere. My line was more than fifteen miles long, extending from Haines' Bluff to Vicksburg, thence to Warrenton. The line of the enemy was about seven. In addition to this, having an enemy at Canton and Jackson, in our rear, who was being constantly reinforced, we required a second line of defence facing the other way. I had not troops enough under my command to man these. General Halleck appreciated the situation and, without being asked, forwarded reinforcements with all possible dispatch.
