General Johnston sent two brigades from Polk's corps, Colonel Russell's and General B.R. Johnson's, to reinforce his extreme left. General Beauregard, who had taken immediate command on the Confederate left, sent them farther to his right, and they went into position on the left of Wood's brigade. Two regiments of Russell's brigade formed on the left of Wood; the rest were marched by General Clark, the division commander, still farther to the right. Three of General Johnson's regiments formed on the right of Russell's two, while General Bragg moved Johnson's remaining two regiments off to his right, to another attack. The assault on Colonel Marsh was made with great fury. In five minutes most of the field officers in the brigade were killed or wounded. The enemy's fire seemed especially directed at Burrow's battery, posted in the centre of Marsh's brigade, all the horses of which were killed or disabled. The colonel and lieutenant-colonel of the Forty-eighth Illinois being wounded and taken off the field, the regiment finally became disorganized and retired in disorder. The other regiments fell back. The battery was lost. The first brigade, which had not been severely engaged, next retired in some disorder. The Third Brigade, being now enfiladed and turned on its left flank, Colonel Raith refused his left regiment, and was himself soon mortally wounded. Wood's brigade then wheeling to its left and advancing, the Third Brigade fell back, leaving Waterhouse's battery on the flank of Sherman's division exposed. The division formed again, its right connected with Sherman's left on the Purdy road. When Sherman fell back from the Purdy road, McClernand adjusted his right to connect again with Sherman's left. While his right connected still with Sherman, his left for a while almost joined W.H.L. Wallace in the position which he had assumed, and, when pushed back still farther, his left was yet to some extent protected by the character of the ground, rough, intersected by ravines, and dotted with impenetrable thickets that intervened between it and W.H.L. Wallace. McAllister's battery, and Schwartz's battery commanded by Lieutenant Nispel, were reinforced by Taylor's battery, commanded by Captain Barrett, brought over from Sherman, and by Dresser's battery, commanded by Captain Timony.
