"Then why ain't you killed, too, you d----d coward?" thundered Nelson. "Gather some of these stragglers and go back into the battle."

The man obeyed the order.

NELSON CROSSING THE TENNESSEE RIVER.

General Nelson reported to General Grant with his division, received his orders, and then dashed about the field, wherever his presence was needed. The division was only slightly engaged before night came on and suspended the battle.

At dawn on the second day the enemy lay in the position it held When darkness ended the fight. The gun-boats had shelled the woods during the night, and prevented the Rebels from reaching the river on our left. A creek and ravine prevented their reaching it on the right. None of the Rebels stood on the bank of the Tennessee River on that occasion, except as prisoners of war.

As they had commenced the attack on the 6th, it was our turn to begin it on the 7th. A little past daylight we opened fire, and the fresh troops on the left, under General Buell, were put in motion. The Rebels had driven us on the 6th, so we drove them on the 7th. By noon of that day we held the ground lost on the day previous.

The camps which the enemy occupied during the night were comparatively uninjured, so confident were the Rebels that our defeat was assured.

It was the arrival of General Buell's army that saved us. The history of that battle, as the Rebels have given it, shows that they expected to overpower General Grant before General Buell could come up. They would then cross the Tennessee, meet and defeat Buell, and recapture Nashville. The defeat of these two armies would have placed the Valley of the Ohio at the command of the Rebels. Louisville was to have been the next point of attack.

The dispute between the officers of the Army of the Tennessee and those of the Army of the Ohio is not likely to be terminated until this generation has passed away. The former contend that the Rebels were repulsed on the evening of the 6th of April, before the Army of the Ohio took part in the battle. The latter are equally earnest in declaring that the Army of the Tennessee would have been defeated had not the other army arrived. Both parties sustain their arguments by statements in proof, and by positive assertions. I believe it is the general opinion of impartial observers, that the salvation of General Grant's army is due to the arrival of the army of General Buell. With the last attack on the evening of the 6th, in which our batteries repulsed the Rebels, the enemy did not retreat. Night came as the fighting ceased. Beauregard's army slept where it had fought, and gave all possible indication of a readiness to renew the battle on the following day. So near was it to the river that our gun-boats threw shells during the night to prevent our left wing being flanked.
