And then Rousseau's Brigade is drawn off in splendid style, as if coming in from parade, conscious of some grand master of reviews watching their movements. So there was--the Rebel general. As he saw the brigade filing back, he pushed his forces forward again. Kirk's Brigade advanced to meet them, coming out of the woods into an open field to do so. They were met by a tremendous fire, which threw a battalion of regulars in front of them (under Major Oliver, I think,) into some confusion. They retire to reform, and meanwhile down drops the brigade, flat on the ground. Then, as the front is clear, they spring up, charge across the open field--never mind the falling--straight on, on to the woods--under cover, with the enemy driven back by the impetuous advance. And now he rallies. Fierce musketry firing sweeps the woods. They advance--thirty rods, perhaps--when the Twenty-ninth Indiana gets into a marsh, and falls partially to the rear. Heavier comes the leaden hail. Twenty-ninth and Thirtieth both fall back fifteen or twenty rods; they rally and advance; again they are hurled back; again they start forward; and this time they come in on the vulnerable points. The enemy flees. Colonel Waggoner's Fifteenth Indiana comes up to the support; the enemy disappear; fresh troops take their places, and for them the fight is ended. I might describe similar deeds of Willich's and Harrison's regiments, but "from one learn all." Farther to the right, McClernand and Hurlbut were gallantly coming on with their jaded men. The soldiers would fight--that was the great lesson of the battle. If surprised, and driven off in consequence of surprise, that can hardly be wholly charged on them. Four times McClernand regained and lost again the ground to the front of his division. Similar were Hurlbut's fortunes. But I must abandon these details. Beginning at the left we have followed the wave of successes that swept us forward again, from spot to spot, over the hard-lost fields of Sunday--our paeans of victory, the wild cheers of our successful soldiers, sounding the requiem of the fallen Rebels, who have atoned for their treason by the brave man's death. Nelson, Crittenden, McCook, Hurlbut, McClernand have borne their divisions through the fray. It lasted longer on the right, and was as rarely interesting as the chess-game of a master. Let us trace it through.
