From this I judged that the existing conditions of the battle would probably require a sacrifice of my command, so I informed Roberts and Schaefer that we must be prepared to meet the demand on us by withstanding the assault of the enemy, no matter what the outcome.

Every energy was therefore bent to the simple holding of our ground, and as ammunition was getting scarce, instructions were given throughout the command to have it reserve its fire till the most effective moment.

In a little while came a second and a third assault, and although they were as daring and furious as the first, yet in each case the Confederates were repulsed, driven back in confusion, but not without deadly loss to us, for the noble Roberts was killed, and Colonel Harrington, of the Twenty-Seventh Illinois, who succeeded to his brigade, was mortally wounded a few minutes later.

I had now on the death-roll three brigade commanders, and the loss of subordinate officers and men was appalling, but their sacrifice had accomplished the desired result; they had not fallen in vain.

Indeed, the bravery and tenacity of my division gave to Rosecrans the time required to make new dispositions, and exacted from our foes the highest commendations.
A lull followed the third fierce assault, and an investigation showed that, with the exception of a few rounds in my brigade, our ammunition was entirely exhausted; and while it was apparent that the enemy was reluctant to renew the conflict in my front, yet I was satisfied I could not hold on much longer without the danger of ultimate capture, so I prepared to withdraw as soon as the troops of Rousseau's division, which had been ordered to take up a line on my right, came into position.
