The plan of General McClellan’s new campaign, commencing on the 26th of October, may best be stated in his own language:

“The plan of campaign I adopted during this advantage was to move the army, well in hand, parallel to the Blue Ridge, taking Warrenton as the point of direction for the main army; seizing each pass on the Blue Ridge by detachments, as we approached it, and guarding them after we had passed as long as they would enable the enemy to trouble our communications with the Potomac. It was expected that we would unite with the Eleventh corps and Sickles’s division near Thoroughfare Gap. We depended upon Harper’s Ferry and Berlin for supplies until the Manassas Gap Railway was reached; when that occurred, the passes in the rear were to be abandoned, and the army massed ready for action or movement in any direction.

“It was my intention if upon reaching Ashby’s or any other pass, I found that the enemy were in force between it and the Potomac in the valley of the Shenandoah, to move into the valley and endeavor to gain their rear.

“I hardly hoped to accomplish this, but did expect that by striking in between Culpeper Court-House and Little Washington I could either separate their army and beat them in detail, or else force them to concentrate as far back as Gordonsville, and thus place the army of the Potomac in position either to adopt the Fredericksburgh line of advance upon Richmond, or to be removed to the Peninsula, if, as I apprehended, it were found impossible to supply it by the Orange and Alexandria Railroad beyond Culpeper.”

On the night of November 7th, General McClellan received an order from Washington, relieving him from the command of the Army of the Potomac, and appointing General Burnside to be his successor. This change was immediately consummated. The army, at this time, was in fine condition and spirits, and was strongly posted near Warrenton, its right wing being across the Rappahannock, and its left resting on Manassas Junction, the front extending along the line of the Orange and Alexandria Railroad. The rebels, under Longstreet, were massed near Culpeper, and it was apparent that a great battle could not long be deferred. Such was the posture of affairs, when General Burnside assumed command of the Army of the Potomac.

The impressive and affecting words of General McClellan, in reference to this passage in our national history, ought here to find a place. They render a merited tribute to the noble army of patriots, which he had led through so many perils.

“I am devoutly grateful to God that my last campaign with this brave army was crowned with a victory which saved the nation from the greatest peril it had then undergone. I have not accomplished my purpose if, by this report, the army of the Potomac is not placed high on the roll of the historic armies of the world. Its deeds ennoble the nation to which it belongs. Always ready for battle, always firm, steadfast and trustworthy, I never called on it in vain; nor will the nation ever have cause to attribute its want of success, under myself, or under other commanders, to any failure of patriotism or bravery in that noble body of American soldiers.

“No man can justly charge upon any portion of that army, from the Commanding General to the private, any lack of devotion to the service of the United States’ Government, and to the cause of the Constitution and the Union. They have proved their fealty in much sorrow, suffering, danger, and through the very shadow of death. Their comrades dead on all the fields where we fought, have scarcely more claim to the honor of a nation’s reverence than their survivors to the justice of a nation’s gratitude.”

The situation of the respective forces was then as follows: The Federal army, reinforced by the divisions of Generals Sigel and Sickles, who had advanced from Washington, occupied all the region east of the Blue Ridge, with the right resting on Harper’s Ferry, and the left extending nearly to Paris, on the road from Aldie to Winchester. The centre was at Snickersville; with Snicker’s Gap in its possession. The Confederate line was on the south side of the Blue Ridge, with the Shenandoah river immediately in its front, extending from Front Royal down to Charlestown, with the great body of their troops massed between Berryville and Winchester. On November 4th Ashby’s Gap was occupied without opposition by the Federal troops. The cavalry corps, under Colonel Pleasanton, pushed on from Piedmont, and occupied Marguette, holding the approaches to Manassas and Chester Gap, on the left side of the Blue Ridge. The condition and spirit of the army at this time were unequalled by that of any force before organized. On the 6th General McClellan’s headquarters were at Rectortown near Front Royal. The army was steadily advancing and the Confederate force falling back, with some skirmishing. Warrenton was occupied by the Federal troops on the same day. On the 7th a severe snow storm commenced, and continued throughout the day. On the 8th the bridge at Rappahannock Station was taken and held by General Bayard.

The next day was devoted by General McClellan to the transfer of his command to General Burnside. The most cordial feelings existed between the two officers, the latter of whom accepted a promotion which he had before twice declined, only upon the peremptory order of the War Department. On Sunday evening his officers assembled at his tent, for a final parting of commander and officers. It was such a scene of deep feeling as could occur only where officers reposed the highest confidence in their commander, who had led them successfully through some of the most fearful battles of modern wars. Monday was occupied in passing among the various camps, reviewing the troops, and taking a final leave of both officers and men. A spectator of these scenes has summed them up in these words:
