With the rapid concentration of troops at Washington, the government again assumed the offensive. General George B. McClellan, having distinguished himself in West Virginia, was called to Washington, at the recommendation of the best military authorities, and intrusted with the command of the Army of the Potomac; and soon after, on the retirement of General Scott, now aged and infirm, and unable to mount a horse, McClellan took his place as commander of all the forces of the United States.

At the beginning of the rebellion McClellan was simply a captain, but was regarded as one of the most able and accomplished officers of the army. His promotion was rapid beyond precedent; but his head was turned by his elevation, and he became arrogant and opinionated, and before long even insulted the President, and assumed the airs of a national liberator on whose shoulders was laid the burden of the war. He consequently estranged Congress, offended Scott, became distrusted by the President, and provoked the jealousies of the other generals. But he was popular with the army and his subordinates, and if he offended his superiors his soldiers were devoted to him, and looked upon him as a second Napoleon.

The best thing that can be said of this general is that he was a great organizer, and admirably disciplined for their future encounters the raw troops which were placed under his command. And he was too prudent to risk the lives of his men until his preparations were made, although constantly urged to attempt, if not impossibilities, at least what was exceedingly hazardous.

It was expected by the President, the Secretary of War, and Congress, that he would hasten his preparations, and advance upon the enemy, as he had over one hundred thousand men; and he made grand promises and gave assurances that he would march speedily upon Richmond. But he did not march. Delay succeeded delay, under various pretences, to the disappointment of the country, and the indignation of the responsible government. It was not till April, 1862, after five months of inaction, that he was ready to move upon Richmond, and then not according to pre-arranged plans, but by a longer route, by the way of Fortress Monroe, up the Peninsula between the York and James rivers, and not directly across Virginia by Manassas Junction, which had been evacuated in view of his superior forces,--the largest army theretofore seen on this continent.

It is not for me, utterly ignorant of military matters, to make any criticism of the plan of operations, in which the President and McClellan were at issue, or to censure the general in command for the long delay, against the expostulations of the Executive and of Congress. He maintained that his army was not sufficiently drilled, or large enough for an immediate advance, that the Confederate forces were greater than his own, and were posted in impregnable positions. He was always calling for reinforcements, until his army comprised over two hundred thousand men, and when at last imperatively commanded to move, some-whither,--at any rate to move,--he left Washington not sufficiently defended, which necessitated the withdrawal of McDowell's corps from him to secure the safety of the capital. Without enumerating or describing the terrible battles on the Peninsula, and the "change of base," which practically was a retreat, and virtually the confession of failure, it may be said in defence or palliation of McClellan that it afterwards took Grant, with still greater forces, and when the Confederates were weakened and demoralized, a year to do what McClellan was expected to do in three months.

The war had now been going on for more than a year, without any decisive results so far as the Army of the Potomac was concerned, but on the contrary with great disasters and bitter humiliations. The most prodigious efforts had been made by the Union troops without success, and thus far the Confederates had the best of it, and were filled with triumph. As yet no Union generals could be compared with Lee, or Johnston, or Longstreet, or Stonewall Jackson, while the men under their command were quite equal to the Northern soldiers in bravery and discipline.

The times were dark and gloomy at the North, and especially so to the President, as commander-in-chief of the army and navy, after all the energies he put forth in the general direction of affairs. He was maligned and misrepresented and ridiculed; yet he opened not his mouth, and kept his soul in patience,--magnanimous, forbearing, and modest. In his manners and conduct, though intrusted with greater powers than any American before him had ever exercised, he showed no haughtiness, no resentments, no disdain, but was accessible to everybody who had any claim on his time, and was as simple and courteous as he had been in a private station. But what anxieties, what silent grief, what a burden, had he to bear! And here was his greatness, which endeared him to the American heart,--that he usurped no authority, offended no one, and claimed nothing, when most men, armed as he was with almost unlimited authority, would have been reserved, arrogant, and dictatorial. He did not even assume the cold dignity which Washington felt it necessary to put on, but shook hands, told stories, and uttered jokes, as if he were without office on the prairies of Illinois; yet all the while resolute in purpose and invincible in spirit,--an impersonation of logical intellect before which everybody succumbed, as firm, when he saw his way clear, as Bismarck himself.

His tact in managing men showed his native shrewdness and kindliness, as well as the value of all his early training in the arts of the politician. Always ready to listen, and to give men free chance to relieve their minds in talk, he never directly antagonized their opinions, but, deftly embodying an argument in an apt joke or story, would manage to switch them off from their track to his own without their exactly perceiving the process. His innate courtesy often made him seem uncertain of his ground, but he probably had his own way quite as frequently as Andrew Jackson, and without that irascible old fighter's friction.

But darker days were yet to come, and more perplexing duties had yet to be discharged. The President was obliged to retire McClellan from his command when, in August, 1862, that general's procrastination could no longer be endured. McClellan had made no fatal blunders, was endeared to his men, and when it was obvious that he could not take Richmond, although within four miles of it at one time, he had made a successful and masterly retreat to Harrison's Landing; yet the campaign against the Confederate capital had been a failure, as many believed, by reason of unnecessary delays on the part of the commander, and the President had to take the responsibility of sustaining or removing him. He chose the latter.

What general would Lincoln select to succeed McClellan? He chose General John Pope, but not with the powers which had been conferred on McClellan. Pope had been graduated at West Point in 1842, had served with distinction in the Mexican War, and had also done good service in the West. But it was his misfortune at this time to lose the second battle of Bull Run, or Manassas, when there was no necessity of lighting. He himself attributed his disaster to the inaction and disobedience of General Porter, who was cashiered for it,--a verdict which was reversed by a careful military inquiry after the war. Pope's defeat was followed, although against the advice of the cabinet, by the restoration of McClellan, since Washington was again in danger. After he had put the capital in safety, McClellan advanced slowly against Lee, who had crossed the Potomac into Maryland with designs on Pennsylvania. He made his usual complaint of inadequate forces, and exaggerated the forces of the enemy. He won, however, the battle of Antietam,--for, although the Confederates afterwards claimed that it was a drawn battle, they immediately retired,--but even then failed to pursue his advantage, and allowed Lee to recross the Potomac and escape, to the deep disgust of everybody and the grief of Lincoln. Encouraged by McClellan's continued inaction, Lee sent his cavalry under Stuart, who with two thousand men encircled the Federal army, and made a raid into Pennsylvania, gathering supplies, and retired again into Virginia, unhindered and unharmed. The President now deprived McClellan again of his command, and that general's military career ended. He retired to private life, emerging again only as an unsuccessful Democratic candidate for the presidency against Lincoln in 1864.
