The general arrangement of the campaign seems to have been settled between Halleck and McClellan on the 5th of September. General Sumner with the Second and Twelfth corps moved up the Potomac by way of Tenallytown, Burnside with the First and Ninth corps moved to Leesboro with a view to covering Baltimore, the front was explored by the cavalry under Pleasonton, and the Sixth Corps, under Franklin, constituted a reserve. [Footnote: Confusion in the numbers of the First and Twelfth corps is found in the records and dispatches, owing to the fact that in the Army of Virginia the corps numbers were not those given them by the War Department. Sigel's, properly the Eleventh Corps, had been called First of that army. Banks's, properly Twelfth, had been called Second, and McDowell's, properly First, had been called Third. In the Maryland campaign Hooker was assigned to McDowell's, and it sometimes figures as First, sometimes as Third; Mansfield was assigned to Banks's. The proper designations after the consolidation were First and Twelfth. Reno had been assigned to the First, but McClellan got authority to change it, and gave it to Hooker, sending Reno back to the Ninth. Official Records, vol. xix. pt. ii. pp. 197, 198, 279, 349.] The preliminary movements occupied the 5th and 6th, but on the 7th the positions were as I have stated them. The principal bodies were designated, respectively, as right and left wings instead of armies. The two corps from the Army of Virginia were separated, one being assigned to the right wing under Burnside, and the other to the left under Sumner.

Late in the night of the 5th I received orders from McClellan's headquarters to march from my position on Upton's Hill through Washington toward Leesboro, [Footnote: Leesboro, a village of Maryland eight or ten miles north of Washington, must be distinguished from Leesburg in Virginia.] as soon as my pickets could be relieved by troops of McDowell's corps. [Footnote: Official Records, vol. xix. pt. ii. p. 183; vol. li. pt. i. p. 789.] My route was designated as by the road which was a continuation northward of Seventh Street, and I was directed to report to General Ambrose E. Burnside, commanding right wing, whose headquarters were in the suburbs of the city on that road. This was in accordance with my wish, expressed to McClellan that I might have active field work. For two or three days we were not attached to a corps, but as the organization of the army became settled we were temporarily assigned to the Ninth, which had been Burnside's, and had been with him in North Carolina. During this campaign it was commanded by Major-General Jesse L. Reno, who had long had a division in it, and had led the corps in the recent battle. We marched from Upton's Hill at daybreak of the 6th, taking the road to Georgetown by Ball's Cross-Roads. In Georgetown we turned eastward through Washington to Seventh Street, and thence northward to the Leesboro road. As we passed General Burnside's quarters, I sent a staff officer to report our progress. It was about ten o'clock, and Burnside had gone to the White House to meet the President and cabinet by invitation. His chief of staff, General J. G. Parke, sent a polite note, saying we had not been expected so soon, and directed us to halt and bivouac for the present in some fields by the roadside, near where the Howard University now is. In the afternoon I met Burnside for the first time, and was warmly attracted by him, as everybody was. He was pre-eminently a manly man, as I expressed it in writing home. His large, fine eyes, his winning smile and cordial manners, bespoke a frank, sincere, and honorable character, and these indications were never belied by more intimate acquaintance. The friendship then begun lasted as long as he lived. I learned to understand the limitations of his powers and the points in which he fell short of being a great commander; but as I knew him better I estimated more and more highly his sincerity and truthfulness, his unselfish generosity, and his devoted patriotism. In everything which makes up an honorable and lovable personal character he had no superior. I shall have occasion to speak frequently of his peculiarities and his special traits, but shall never have need to say a word in derogation of the solid virtues I have attributed to him. His chief-of-staff, General Parke, was an officer of the Engineers, and one of the best instructed of that corps. He had served with distinction under Burnside in North Carolina, in command of a brigade and division. I always thought that he preferred staff duty, especially with Burnside, whose confidence in him was complete, and who would leave to him almost untrammelled control of the administrative work of the command.
On September 7th I was ordered to take the advance of the Ninth Corps in the march to Leesboro, following Hooker's corps. It was my first march with troops of this army, and I was shocked at the straggling I witnessed. The "roadside brigade," as we called it, was often as numerous, by careful estimate, as our own column moving in the middle of the road. I could say of the men of the Kanawha division, as Richard Taylor said of his Louisiana brigade with Stonewall Jackson, that they had not yet learned to straggle. [Footnote: See Taylor's "Destruction and Reconstruction," p. 50, for a curious interview with Jackson.] I tried to prevent their learning it. We had a roll-call immediately upon halting after the march, and another half an hour later, with prompt reports of the result. I also assigned a field officer and medical officer to duty at the rear of the column, with ambulances for those who became ill and with punishments for the rest. The result was that, in spite of the example of others, the division had no stragglers, the first roll-call rarely showing more than twenty or thirty not answering to their names, and the second often proving every man to be present. [Footnote: See letters of General R. B. Hayes and General George Crook, Appendix B.] In both the Army of the Potomac and the Army of Northern Virginia the evil had become a most serious one. After the battle of Antietam, for the express purpose of remedying it, McClellan appointed General Patrick Provost-Marshal with a strong provost-guard, giving him very extended powers, and permitting nobody, of whatever rank, to interfere with him. Patrick was a man of vigor, of conscience, and of system, and though he was greatly desirous of keeping a field command, proved so useful, indeed so necessary a part of the organization, that he was retained in it against his wishes, to the end of the war, each commander of the Army of the Potomac in turn finding that he was indispensable. [Footnote: I have discussed this subject also in a review of Henderson's Stonewall Jackson, "The Nation," Nov. 24, 1898, p. 396.]
The Confederate army suffered from straggling quite as much, perhaps, as ours, but in a somewhat different way. At the close of the Antietam campaign General Lee made bitter complaints in regard to it, and asked the Confederate government for legislation which would authorize him to apply the severest punishments. As the Confederate stragglers were generally in the midst of friends, where they could sleep under shelter and get food of better quality than the army ration, this grew to be the regular mode of life with many even of those who would join their comrades in an engagement. They were not reported in the return of "effectives" made by their officers, but that they often made part of the killed, wounded, and captured I have little doubt. In this way a rational explanation may be found of the larger discrepancies between the Confederate reports of casualties and ours of their dead buried and prisoners taken.
The weather during this brief campaign was as lovely as possible, and the contrast between the rich farming country in which we now were, and the forest-covered mountains of West Virginia to which we had been accustomed, was very striking. An evening march, under a brilliant moon, over a park-like landscape with alternations of groves and meadows which could not have been more beautifully composed by a master artist, remains in my memory as a page out of a lovely romance. On the day that we marched to Leesboro, Lee's army was concentrated near Frederick, behind the Monocacy River, having begun the crossing of the Potomac on the 4th. There was a singular dearth of trustworthy information on the subject at our army headquarters. We moved forward by very short marches of six or eight miles, feeling our way so cautiously that Lee's reports speak of it as an unexpectedly slow approach. The Comte de Paris excuses it on the ground of the disorganized condition of McClellan's army after the recent battle. It must be remembered, however, that Sumner's corps and Franklin's had not been at the second Bull Run, and were veterans of the Potomac Army. The Twelfth Corps had been Banks's, and it too had not been engaged at the second Bull Run, its work having been to cover the trains of Pope's army on the retrograde movement from Warrenton Junction. Although new regiments had been added to these corps, it is hardly proper to say that the army as a whole was not one which could be rapidly manoeuvred. I see no good reason why it might not have advanced at once to the left bank of the Monocacy, covering thus both Washington and Baltimore, and hastening by some days Lee's movement across the Blue Ridge. We should at least have known where the enemy was by being in contact with him, instead of being the sport of all sorts of vague rumors and wild reports. [Footnote: McClellan was not wholly responsible for this tardiness, for Halleck was very timid about uncovering Washington, and his dispatches tended to increase McClellan's natural indecision. Official Records, vol. xix. pt. ii. p. 280.]
The Kanawha division took the advance of the right wing when we left Leesboro on the 8th, and marched to Brookville. On the 9th it reached Goshen, where it lay on the 10th, and on the 11th reached Ridgeville on the railroad. The rest of the Ninth Corps was an easy march behind us. Hooker had been ordered further to the right on the strength of rumors that Lee was making a circuit towards Baltimore, and his corps reached Cooksville and the railroad some ten miles east of my position. The extreme left of the army was at Poolesville, near the Potomac, making a spread of thirty miles across the whole front. The cavalry did not succeed in getting far in advance of the infantry, and very little valuable information was obtained. At Ridgeville, however, we got reliable evidence that Lee had evacuated Frederick the day before, and that only cavalry was east of the Catoctin Mountains. Hooker got similar information at about the same time. It was now determined to move more rapidly, and early in the morning of the 12th I was ordered to march to New Market and thence to Frederick. At New Market I was overtaken by General Reno, with several officers of rank from the other divisions of the corps, and they dismounted at a little tavern by the roadside to see the Kanawha division go by. Up to this time they had seen nothing of us whatever. The men had been so long in the West Virginia mountains at hard service, involving long and rapid marches, that they had much the same strength of legs and ease in marching which was afterward so much talked of when seen in Sherman's army at the review in Washington at the close of the war. I stood a little behind Reno and the rest, and had the pleasure of hearing their involuntary exclamations of admiration at the marching of the men. The easy swinging step, the graceful poise of the musket on the shoulder, as if it were a toy and not a burden, and the compactness of the column were all noticed and praised with a heartiness which was very grateful to my ears. I no longer felt any doubt that the division stood well in the opinion of my associates.
