I asked, further, how many men were engaged, and learned with additional astonishment that the detachment from our own regiment—only eight men—was all. This force seemed totally inadequate to the greatness of the work, but I understood that the risk of detection would multiply with the increase of numbers. The very smallest number that could serve was, therefore, selected. If they succeeded, few were better than many.

After a long conversation, Mitchel and I returned to the working-party down the river. The burnt remnants of the old railroad bridge and the rapidly rising timbers of the new had now a deeper interest than ever. The completion of this bridge and the burning of some others far in the South were the two events for which that whole division, whose tents dotted the meadows behind us, was unconsciously waiting. My head was full of conjectures and plans as I walked back through the twilight to join my messmates in the tent. I could talk to no one of what I had heard, but as I lay awake that night a most important resolution took shape. I was weary of the slow movement of the army, and of the monotony of a private soldier's service. While trying carefully to do all my duty, and winning a fair degree of approval from my officers, I yet had no taste for military affairs. If by a little extra hazard I could do more for the country, while getting rid of distasteful routine and entering into a new sphere of work, I was more than willing to accept all the hazard involved. It was too late to take part in the present attempt, but I resolved to be prepared for any opportunity of the kind that might again offer.

Accordingly, in the forenoon of the next day I went up to regimental headquarters and told Colonel L. A. Harris, of the Second Ohio, that I had a favor to ask of him. Major (since General) Anson G. McCook, in whose company I had served during the first three months of the war, was also present. I told them I had ascertained that some of our men had been sent out on secret service lately, and that if any similar details should be made in the future, I wanted the opportunity of being included. Major McCook, while saying some kind things about me, intimated a doubt whether my defective vision—I was very near-sighted—might not be a hindrance on any perilous service. Colonel Harris, however, took a different view of the matter, saying he thought that if I dressed in citizen's clothes, and wore my spectacles (as I was accustomed to do even in the ranks), no person in the South would suspect me of being a soldier, and I was thus only the better fitted for any secret service. McCook did not press his objection, and after learning the reason for my request and trying in vain to find the source of my information, Colonel Harris said,—

"Pittenger, I don't know that we will ever send any more men out of camp in this manner, but I will give my promise that if we do, you shall be the first man called upon."

This was perfectly satisfactory. I returned to my duty, and in the routine of camp-life waited for several days in impatient anxiety. I dreamed at night of burning bridges and startling adventures. Duty on picket and in the camp lines, however, with other excitements, began to weaken the impression, as day after day rolled by with no recurrence of the subject. But one day it was told me by a friend that one of the missing men, a member of Company C, was back again in his usual place in line. For some time attempts to get him to say where he had been, and whether alone or in company, were in vain. He would speak no word by which any one could divine the nature of his errand while away from us, or the degree of success he had met with. I was much disquieted by his return alone, but having no special acquaintance, I did not like to try to get any information directly from him. But I soon learned that he had gone as far as Chattanooga and had turned back,—some of his comrades afterwards thought because he became so sensible of the difficulties of his attempt that he resolved to go no further in it,—a determination which he had a perfect right to make, and which in no way impugned his character as a soldier. His own explanation, afterwards given, which I saw no reason to doubt, was more dramatic. He said that he had gone in disguise as far as Chattanooga, but had there been recognized by a rebel soldier, who was an old acquaintance, and who knew that he belonged to the Union army. This man heard him telling his false story in a public place without contradicting him, but as soon as he could do so unobserved, drew him aside and declared that he remembered him, and knew he was down there disguised for some bad purpose; but that if he would pledge himself to return immediately to the Union lines, he would, for the sake of their former friendship, refrain from denouncing him, otherwise his own sense of duty would require him to report all he knew to the commander of the post. Under such circumstances our comrade judged it most prudent to give and keep the pledge required.

At length the bridge over Stone River was completed, and there was great rejoicing as the first train, laden with army supplies, passed over it from Nashville. Next morning the order was given to the whole division to prepare three days' rations. This was invariably the signal for a decided movement. Our lost comrades were still away, and no word had reached the rank and file of the army of any unusual occurrence southward. The uneasiness of General Mitchel and the regimental officers of the Second Ohio, and especially of Captain Sarratt, who commanded the company to which I belonged, and my friend, Captain Mitchel, was apparent to any careful observer.

Just before the march began, while we were standing in line early the next morning, with the camp all broken up, our knapsacks swung, and our haversacks filled with rations, waiting only for the word "forward," Captain Mitchel came over to me and uttered a sentence, in a half whisper, that went through me like an electric shock. His message was simply this: "Mills is back, and has gone up to headquarters to report." While standing in my place in the ranks I could give no answer, nor could I ask any question, but my mind was full of surmises. Had the adventurers succeeded, and were we now on our way to do our part in the great plan,—to strike swift and far into the South, while the enemy's communications were broken? That would involve hard fighting and stirring scenes not far ahead. Had they failed? If so, there would probably be other attempts,—that is, if the secret had been kept,—and then I would have a part in the risk and the adventure. At any rate, I was exceeding glad of Mills's return, and I knew that I would find out all about it as soon as I could get to talk with him alone. As Company K—Mitchel's—was next my own in the line, that opportunity, even on the march, would not be long delayed.

Soon the command to march was given, and the column moved southward towards Shelbyville, about twenty-five miles distant. Before noon I dropped out of my place, sought and found Mills, and as we plodded along, in the loose order allowed on long marches, we had no difficulty in remaining together, and yet far enough from other soldiers to talk in perfect security. The whole history of my relative's adventures was fully laid open before me. I found that all Mitchel had narrated was perfectly accurate, but the enormous obstacles to be encountered by such an expedition were now brought much more plainly into view. Mills said that he and his companions had first of all exchanged their uniforms for citizen's clothes, and made provision for the safety of their arms and personal effects in the camp. Then, under the direction of Andrews, they had scattered in the mountains, to the eastward of our camp, representing themselves as refugees from the oppressions of the Union troops in Kentucky, and had journeyed thus to Chattanooga. That town had been reached in about four days. My friend pictured in lively colors the manner in which he had been compelled to verbally abuse the Union cause, and join in praise of the leaders and principles of Secession. The squad to which he belonged had no particular difficulty in passing themselves as good rebels. The man who first returned had been less fortunate. At Chattanooga they took passage on the cars for Atlanta, and in due time reached that place, where they scattered themselves among the several hotels and lived plentifully (they had an abundant supply of money) for three days longer. Each hour Andrews anticipated the arrival of that Confederate engineer of whom Mitchel had spoken to me. But he did not come. All possible inquiries were guardedly made concerning him, for it was not safe to appear too inquisitive.

"How did you feel while thus waiting in suspense?" I asked.

"I felt as if I wanted to be back in camp, and had no business to be in that town any longer," replied Frank. "To hear the curses and threats made against everything that belonged to the Union, and to be obliged to keep perfectly quiet, or to agree with them, was more than I could easily endure. And the folks about the hotel were more anxious every day to know who I was, and I had to tell them lies without number. I resolved not to stand it much longer."
