Crittenden and McCook advanced a little later. They came upon the enemy, which had quiet possession of McClernand's and Sherman's camps. Beauregard's head-quarters were there. The Rebels, finding themselves assailed, made a desperate effort to drive back the advancing columns. Rousseau advanced across the open field, over the ground so hotly contested by McClernand the day before. This movement made a gap between McCook and Crittenden. Beauregard saw it, threw Cheatham and Withers into the open space. They swung round square against Rousseau's left, pouring in a volley which staggered the advancing regiments. The Thirty-second Indiana regiment, Colonel Willich commanding, was on the extreme right of McCook's division. They had been in battle before, and were ordered across to meet the enemy. You see them fly through the woods in rear of Rousseau's brigade. They are upon the run. They halt, dress their ranks as if upon parade, and charge upon the Rebels. Colonel Stambough's Seventy-seventh Pennsylvania follows. Then all of Kirk's brigade. It is a change of position and a change of front, admirably executed, just at the right time, for Rousseau is out of ammunition, and is obliged to fall back. McCook's third brigade, General Gibson, comes up. Rousseau is ready again, and at eleven o'clock you see every available man of that division contending for the ground around the church. Meanwhile Wallace is moving over the ground on the extreme right, where Sherman fought so bravely. Sherman, Hurlburt, and the shattered regiments of W. H. L. Wallace's division, now commanded by McArthur, follow in reserve. Driven back by Nelson, the Rebel forces concentrate once more around the church for a final struggle. Wallace watches his opportunities. He gains a ridge. His men drop upon the ground, deliver volley after volley, rise, rush nearer to the enemy, drop once more, while the grape and canister sweep over them. Thus they come to close quarters, and then regiment after regiment rises, and delivers its fire. It is like the broadsides of a man-of-war. The time had come for a general advance. Nelson, Crittenden, McCook, Wallace, almost simultaneously charged upon the enemy. It was too powerful to be resisted. The Rebels gave way, retreated from the camps which they had occupied a single night, fled past the church, across the brook, up through the old cotton-field on the south side, to the shelter of the forest on the top of the ridge beyond. The battle was lost to them. Exultant cheers rang through the forest for the victory won.
