One did, and it was my luck to see it win. I had been sent by my chief, General Hazen, to order up some artillery ammunition and rode away to the right and rear in search of it. Finding an ordnance train I obtained from the officer in charge a few wagons loaded with what I wanted, but he seemed in doubt as to our occupancy of the region across which I proposed to guide them. Although assured that I had just traversed it, and that it lay immediately behind Wood's division, he insisted on riding to the top of the ridge behind which his train lay and overlooking the ground. We did so, when to my astonishment I saw the entire country in front swarming with Confederates; the very earth seemed to be moving toward us! They came on in thousands, and so rapidly that we had barely time to turn tail and gallop down the hill and away, leaving them in possession of the train, many of the wagons being upset by frantic efforts to put them about. By what miracle that officer had sensed the situation I did not learn, for we parted company then and there and I never again saw him. By a misunderstanding Wood's division had been withdrawn from our line of battle just as the enemy was making an assault. Through the gap of half a mile the Confederates charged without opposition, cutting our army clean in two. The right divisions were broken up and with General Rosecrans in their midst fled how they could across the country, eventually bringing up in Chattanooga, whence Rosecrans telegraphed to Washington the destruction of the rest of his army. The rest of his army was standing its ground. A good deal of nonsense used to be talked about the heroism of General Garfield, who, caught in the rout of the right, nevertheless went back and joined the undefeated left under General Thomas. There was no great heroism in it; that is what every man should have done, including the commander of the army. We could hear Thomas's guns going--those of us who had ears for them--and all that was needful was to make a sufficiently wide detour and then move toward the sound. I did so myself, and have never felt that it ought to make me President. Moreover, on my way I met General Negley, and my duties as topographical engineer having given me some knowledge of the lay of the land offered to pilot him back to glory or the grave. I am sorry to say my good offices were rejected a little uncivilly, which I charitably attributed to the general's obvious absence of mind. His mind, I think, was in Nashville, behind a breastwork.
