As they reached the next woody ridge, Rebel cavalry, that had crossed the creek lower down, were seen coming up on their left; and to resist this new attack the line of battle was formed, fronting in that direction. For three quarters of an hour the brigade stood here. The cavalry, finding its purpose foiled, did not come within range. In front they were hard pressed, and the Rebels, who had followed Prentiss, began to come in on their right. Colonel Stuart had sent across to Brigadier-General W. H. L. Wallace, then not engaged, for support. Brigadier-General McArthur's Brigade was promptly started across, but mistaking the way, and bearing too much on the right, it speedily found itself in the midst of the Rebel forces, that had poured in after Prentiss. General McArthur could thus render Stuart's Brigade no assistance, but he vigorously engaged the Rebels to his front and flanks, fell back to a good position, and held these troops in bay till the rest of his division came up to his aid. General McArthur was himself disabled by a wound in the foot, but he rode into a hospital, had it dressed, and returned to the brigade, which meantime sturdily held its position. But this brought Stuart's isolated brigade little help. They were soon forced to fall back to another ridge, then to another, and finally, about 12 o'clock, badly shattered and disordered, they retreated to the right and rear, falling in behind General McArthur's Brigade to reorganize. Colonel Stuart was himself wounded by a ball through his right shoulder, and the loss of field and company-officers was sufficient to greatly discourage the troops. This clears our entire front line of divisions. The enemy has full possession of all Sherman's, Prentiss's, and McClernand's camps. By 10 o'clock our whole front, except Stuart's Brigade, had given way, and the burden of the fight was resting on Hurlbut and W. H. L. Wallace. Before 12 Stuart, too, had come back, and for the time absolutely only those two divisions stood between our army and destruction or surrender.
