To meet this greatest danger, Wood's division of the Fourth Corps was crossed to the north side to support the cavalry in holding the fords above, if that should become necessary; while Wagner's division, which had acted as rear-guard from Spring Hill, was ordered to remain far enough in front of the line to compel Hood to disclose his intention to attack in front or to turn the position, and was to retire and take its position in reserve at the proper time, if the enemy formed for attack. Only one of those three brigades—Opdycke's—came in at the proper time and took its appropriate place; and that, it was asserted, and no doubt truly, was by the brigade commander's own volition, he having been a soldier enough to know his duty in such a case, without the necessity for any orders. The other two brigades remained in their advanced position until they were run over by the enemy. Much idle controversy was indulged in among officers of the Fourth Corps and others in respect to the action of those two brigades. The only proper way to settle such a question was by a court-martial. As the corps passed from my command the next morning, and had been under by orders only a few days, I have never made any effort to fix, even in my own mind, the responsibility for that blunder.

By great exertion on the part of the engineers, the means of crossing the river were at length provided. The supports of the burned wagon-bridge were still standing at a level with the surface of the water. They were timbered and planked over, and the railroad bridge was also covered with planking, thus giving us two passable bridges. The trains had all been crossed over, and a part of the artillery. Orders had been issued for the troops to begin crossing at dark, when Hood disclosed his purpose to attack. The artillery was ordered back to its position in line, and General Stanley and I, who were then together on the north side of the river, rode rapidly to our posts, he to his corps on the south side, and I to the high redoubt on the north bank, overlooking the entire field.

There I witnessed the grandest display possible in war. Every battalion and battery of the Union army in line was distinctly seen. The corps of the Confederate army which were advancing or forming for the attack could also be seen, though less clearly on account of their greater distance, while the Confederate cavalry could be dimly discerned moving to the fords of the river above Franklin. Only a momentary view was permitted of this scene of indescribable grandeur when it was changed into one of most tragic interest and anxiety. The guns of the redoubt on the parapet of which I stood with two or three staff officers had fired only a few shots over the heads of our troops at the advancing enemy when his heavy line overwhelmed Wagner's two brigades and rapidly followed their fragments in a confused mass over our light intrenchments. The charging ranks of the enemy, the flying remnants of our broken troops, and the double ranks of our first line of defense, coming back from the trenches together, produced the momentary impression of an overwhelming mass of the enemy passing over our parapets.

HOOD'S FORMIDABLE ATTACK

It is hardly necessary to say that for a moment my "heart sank within me." But instantly Opdycke's brigade and the 12th and 16th Kentucky sprang forward, and steadily advanced to the breach. Up to this moment there had been but little firing at that point, because of our own troops and the enemy coming in pell-mell; hence there was not much smoke, and the whole could be seen. But now all became enveloped in a dense mass of smoke, and not a man was visible except the fragments of the broken brigades and others, afterward known to be prisoners, flocking to the rear. A few seconds of suspense and intense anxiety followed, then the space in the rear of our line became clear of fugitives, and the steady roar of musketry and artillery and the dense volume of smoke rising along the entire line told me that "the breach is restored, the victory won"! That scene, and the emotion of that one moment, were worth all the losses and dangers of a soldier's lifetime.

It would hardly be possible to frame language that would do more than justice to the magnificent conduct of Emerson Opdycke's brigade and Laurence H. Rousseau's 12th Kentucky and John S. White's 16th Kentucky, which were also in reserve, and their commanders, in that battle. Their action was beyond all praise, and nothing that can justly be said in respect to the battle can detract one iota from their proud fame. Yet the light in which the part acted by Opdycke's brigade (the others not being mentioned) is presented by some "historians," to the prejudice, relatively, of other portions of the army and of their commanders, is essentially false. It is represented as something purely spontaneous, out of the ordinary course, not contemplated in the dispositions made for battle, unforseen and unexpected; in short, something more—yes, vastly more—than the reasonable duty of the brigade; or, "beyond all power of generalship to mold the battle or control its issue, the simple charge of Opdycke's brigade stands in boldest relief." The same might be said with equal truth of the action of any brigade upon which devolves the assault of defense of the key of a military position. The success or failure of "generalship to mold the battle or control its issue" depends absolutely upon the action of such brigades, their doing, or failure to do, the duty belonging to the position to which they are assigned. Every soldier in the army knew what his duty was in such a case—knew for what he had been placed in that position. It would have been strange indeed if the gallant commander of that brigade had waited for orders from some higher officer to move "forward to the lines." As well might the commander of a brigade in line wait for orders from the general-in- chief before commencing to fire on the advancing enemy.

The highest tribute that can be paid to Opdycke's brigade is the just and true one, that it did exactly the duty assigned it in the plan of battle, and did that duty nobly and with complete success. That other brigades did the same is sufficiently shown by the fact that twenty battle-flags were captured by a single brigade of the Twenty-third Corps on the same part of the line, and that the 12th and 16th Kentucky regiments relatively suffered equally heavy losses in killed and wounded with those of Opdycke.( 2)

SERIOUS ERROR OF TWO BRIGADES

As before stated, the dispositions for defense contemplated the whole of Wagner's division as the reserve to support the center, that being the only part of the line upon which the enemy would have time to make a heavy assault that day. This provision for an ample reserve had been made after full consideration and before Wood's division was ordered to the north side of the river, which was after the day was well advanced and the enemy's cavalry had begun to threaten the crossing above. The blunder respecting the two brigades of Wagner's division came near being disastrous, and the repulse of the assault in spite of that blunder makes it highly probable that if the dispositions ordered had been properly made, the repulse of the enemy would have been easy beyond reasonable doubt. Yet it would be difficult to find a fairer chance of success in a direct assault upon troops in position. Our intrenchments were of the slightest kind, and without any considerable obstructions in front to interfere seriously with the assault. The attack, no less than the defense, was characterized by incomparable valor, and the secret of its failure is to be found in one of the principles taught by all military experience—the great superiority in strength of a fresh body of troops in perfect order over another in the state of disorder which necessarily results from even the most successful assault. There was really no comparison, in effective strength, between Opdycke's orderly and compact brigade and the confused mass of Confederates that were crossing over our parapet. The result was nothing extraordinary or at all unprecedented. It was but one of the numerous proofs afforded by military history of the value of that prudent maxim in the art of war which dictates the placing of a suitable reserve in close support of that portion of a defensive line which is liable to heavy assault.

The surprising conduct of the commanders of the two brigades of Wagner's division which were run over by the enemy, and of the division commander himself, whatever may be true as to the conflicting statements published in respect to their action, is one of the strongest possible illustrations of the necessity of the higher military education, and of the folly of intrusting high commands to men without such education, which, fortunately for the country and the army, is rarely learned by experience, but must be acquired by laborious study of the rules and principles laid down by standard authors as derived from the practice and teachings of the great masters of the art of war in all ages. A well-educated officer, either as brigade or division commander, would not have needed orders from any source to tell him what to do in that emergency. He would have known so surely what his duty was that he would have retired at the proper time behind the main line, without ever thinking whether or not he had orders to do so. As well might I have waited for orders from General Thomas to retire across the Harpeth after my duty on the south side of that river had been accomplished. The cases are closely parallel. Any unofficial discussion of the question of responsibility for the sacrifice of those two brigades is idle. According to the established rules of war, those three commanders ought to have been tried by court- martial, and, if found guilty, shot or cashiered, for sacrificing their own men and endangering the army. One example of such punishment would do much to deter ignorant and incompetent men from seeking high commands in the field. But the discipline of the volunteer army of a republic must, it appears, inevitably be, especially in respect to officers of high rank, quite imperfect, although it may become in respect to the great mass of the troops, as ours certainly did, exceedingly efficient.
