One brigade of the Confederate army did not receive this order, and when Nelson's advance crossed the river this brigade was charging the line of cannon on the left. These cannon were entirely unprotected by infantry, and Grant himself placed Nelson's men in line as they arrived.
The Confederate brigade was advancing with triumphant shouts, when they were met with a withering volley and sent reeling back. Then, to his surprise, the commander found that of all of the Confederate army his brigade was the only one continuing the fight, and he hastily fell back. The battle for the day was over.
Alone and practically unaided the brave soldiers of the Army of the Tennessee had fought the battle of Sunday and saved themselves from capture. To them belongs the glory.
The battle of Monday was mainly the fight of the Army of the Ohio. Without its aid Grant could never have been able to turn defeat into victory, and send the Confederate hosts in headlong flight back to Corinth. There would have been no advance Monday morning if Buell had not been on the field. The whole energy of Grant would have been devoted to the saving of what remained of his army.
The terrible conflict of the day had left its impress on the Army of the Tennessee. There was but a remnant in line capable of battle when night came.
The generals of divisions were so disheartened that the coming of Buell failed to restore their spirits. Even the lion-hearted Sherman wavered and was downcast. Grant found him sitting in the darkness beside a tree, his head buried in his hands, and his heart full of fears. He had fought as generals seldom fight. Three horses had been shot under him, and he had received two wounds. When Grant told him there was to be an advance in the morning, he sadly shook his head and said: "No use, General, no use; the fight is all out of the men. I do not possibly see how we can assume the offensive."
"Look here, Sherman," replied Grant. "Remember how it was at Donelson. If we assume the offensive in the morning a glorious victory awaits us. Lew Wallace is here; Buell will have at least 20,000 fresh troops on the field. The Confederates, like ourselves, are exhausted and demoralized. If we become the aggressors, success is sure."
Sherman became convinced; his fears were gone, his hopes revived.
Why was it that the fiery and impetuous Nelson was so late in getting on the field? He was only nine miles away early in the morning, and had received orders from Grant to move his division opposite Pittsburg Landing. If there had been any roads there would have been no excuse for his delay. But a heavily timbered, swampy bottom lay between him and his destination. The river had been very high, overflowing the whole bottom, and when the water had receded it left a waste of mud, from which all vestige of a road had disappeared. To plunge into that waste of mud and wilderness without a guide would have been madness. A guide, though Grant said one could easily be found, could not be secured. So Nelson sent a staff officer to see if he could find a practicable route. This officer did not return until noon. All of this time the division lay listening to the booming of cannon and eager to be led to the fray. As for Nelson, he fretted and fumed, stormed and swore at the delay.
