During the months of January and February, the committee made repeated visits to the President for the purpose of urging the division of the Army of the Potomac and its organization into army corps. We insisted upon this on the strength of the earnest recommendations of our chief commanders, and with a view to greater military efficiency; but the President said General McClellan was opposed to it, and would, he believed, resign his command in the alternative of being required to do it. Mr. Lincoln said he dreaded "the moral effect of this"; but in the latter part of February, he began to lose his faith in the General, and finally, after nearly two months of perseverance by the committee, he gave his order early in March, which General McClellan obeyed with evident hesitation and very great reluctance. A few days later the long-tried patience of the President became perfectly exhausted. He surprised and delighted the committee by completely losing his temper, and on the 11th relieved General McClellan from the command of all our forces except the Army of the Potomac. The rebels, in the meantime, had evacuated their works at Centreville and Manassas, and retreated with their munitions in safety. A majority of the committee at this time strongly suspected that General McClellan was a traitor, and they felt strengthened in this suspicion by what they afterward saw for themselves at Centreville and Manassas, which they visited on the thirteenth of March. They were certain, at all events, that his heart was not in the work. He had disregarded the President's general order of the nineteenth of January, for a movement of all our armies, which resulted in the series of victories of Fort Henry, Fort Donelson, etc., which so electrified the country. He had protested against the President's order of the thirty-first of January, directing an expedition for the purpose of seizing a point upon the railroad southwest of Manassas Junction. He had opposed all forward movements of the Army of the Potomac, and resolutely set his face against the division of our forces into army corps, as urged by all our chief commanders. And he had again and again refused to co-operate with the navy in breaking up the blockade of the Potomac, while his order to move in the direction of the enemy at Centreville and Manassas was given after the evacuation of these points.
