certainly was never a part of my instructions, but these brigades had orders from General Wagner not to retire to the main line until forced to do so by the fighting of the enemy. The consequence was that the brigades stood their ground until the charging rebels were almost crossing bayonets with them, but the line them broke-Conrad's brigade first, then Lane's-and men and officers made the quickest time they could to our main lines. The old soldiers all escaped, but the conscripts being afraid to run under fire, many of them were captured. Conrad's brigade entered the main line near the Columbia pike, Colonel Lane's several hundred yards to the right of the pike. A large proportion of Lanes' men came back with loaded muskets, and turning at the breast-works, they fired a volley into the pressing rebels now not ten steps form them. The part of the Twenty-third Corps stationed in the works for a distance of about three [hundred] or four [hundred] yards to the right of the Columbia pike, and which space took in the First Kentucky and Sixth Ohio Batteries, broke and ran to the rear with the fugitives from Conrad's brigade. To add to the disorder the caissons of the two batteries galloped rapidly to the rear, and the enemy appeared on the breast-works and in possession of the two batteries, which they commenced to turn upon us. It was at this moment I arrived at the scene of disorder, coming from the town on the Columbia pike; the moment was critical beyond any I have known in any battle-could the enemy hold that part of the line, he was nearer to our two bridges than the extremities of our line. Colonel Opdycke's brigade was lying down about 100 yards in rear of the works. I rode quickly to the left regiment and called to them to charge; at the same time I saw Colonel Opdycke near the center of his line urging his men forward. I have the colonel no order, as I saw him engaged in doing the very thing to save us, viz, to get possession of our line again. The retreating men of Colonel Conrad's brigade, and, I believe, the men of the Twenty-third Corps, seeing the line of Opdycke's brigade start for the works, commenced to rally. I heard the old soldiers call out, "Come on, men, we can go wherever the general can," and making a rush, our men immediately retook all the line, excepting a small portion just in front of the brick house on the pike. A force of the rebels held out at this point, and for fifteen or twenty minutes, supported by a rebel line fifty yards to the rear, poured in a severe fire upon our men. So deadly was this fire that it was only be the most s trueness exertions of the officers that our men could be kept to the line; our exertions, however, succeed, and in twenty minutes our front was comparatively clear of rebels, who fell back to the position formerly held by the two brigades of the Second Division in the commencement of the fight, from whence they kept up a fire until midnight, when we withdrew. Just after the retaking of the line by our troops, as I was passing toward the left to General Cox's position, my horse was killed, and no sooner had I regained my feet than I received a musket-ball through the back of my neck. My wound, however, did not prevent my keeping the field, and General Cox kindly furnished me a remount. The rapidity of the firing made it very difficult to keep up the ammunition, the train being some two miles distant on the road to Nashville when the battle commenced, and our greatest danger at one period of the battle was that we would exhaust our ammunition. One hundred wagon-loads of ammunition, artillery and musket cartridges, were expended in this short battle, belonging to the ordnance train of the Fourth Army Corps; this train, however, supplied in great part the wants of the Twenty-third Corps.
