Unfortunately, however, the honors which were showered upon McClellan turned his head, and the young commander not only failed to comprehend the situation and his relations to the President and General Scott, but very soon developed signs of vanity and insubordination which caused the President great concern. He saw himself followed and flattered by statesmen, politicians, and soldiers of twice his age and experience. The members of the Cabinet and even the President himself came to his residence to ask his advice, and the venerable hero of the Mexican War deferred to his judgment and accepted his suggestions without hesitation. McClellan was the idol of the army and a magnet that attracted all the interest, influence, and ambition that were centred at Washington at that period of the war. His state of mind and weakness of character were exhibited in letters he wrote to his family at this time, which, by a lamentable error of judgment, were afterwards printed in his biography.

On July 27 he wrote his wife, "I find myself in a new and strange position here, President, Cabinet, General Scott and all deferring to me. By some strange operation of magic I seem to have become the power of the land."

A little later he wrote, "They give me my way in everything, full swing and unbounded confidence. Who would have thought when we were married that I should so soon be called upon to save my country?" Ten days after his appointment he declared, "I would cheerfully take the dictatorship and agree to lay down my life when the country is saved."

Very soon, however, the tone of his letters began to change. The President, General Scott, and the Cabinet had evidently begun to detect his weakness and egotism and no longer accepted his own estimate of his ability and importance. To the President's profound disappointment, he realized within a few days that McClellan was not a staff that could be leaned upon, while General Scott's admiration and confidence in his young lieutenant were shaken at their first interview.

With the air of an emperor McClellan began to issue extraordinary demands upon the President, the War Department, and the Treasury. It soon became apparent that he desired and expected to be placed in command of the greatest army of history; that he intended to organize and equip it according to the most advanced scientific theories; and when the President, the Secretary of War, and General Scott objected to the magnitude of his plans, pointed out their impracticability, and urged him to do something to check the alarming movements of the Confederates, he was seized with a delusion which remained with him to the end, that they were endeavoring to thwart and embarrass him. The tone of his letters to his wife was radically changed.

"I am here in a terrible place," he said; "the enemy have from three to four times my force; the President and the old General will not see the true state of affairs."

"I am weary of all this," he said a week later, "and disgusted with this administration,—perfectly sick of it;" and he declared that he remained at the head of affairs only because he had become convinced that he was alone the salvation of the country. He expressed especial contempt for the President, and said, "There are some of the greatest geese in the Cabinet I have ever seen,—enough to tax the patience of Job." The incompetence and stupidity of the President, he wrote, was "sickening in the extreme, and makes me feel heavy at heart when I see the weakness and unfitness of the poor beings who control the destinies of this country."

He wrote other friends that his wisdom alone must save the country, that he spent his time "trying to get the government to do its duty, and was thwarted and deceived by these incapables at every turn." He demanded that all recruits be sent to his army and that all supplies be issued to him, as if the armies in the Mississippi Valley could take care of themselves. He demanded that "the whole of the regular army, old and new, be at once ordered to report here," and that the trained officers be assigned to him. "It is the task of the Army of the Potomac to decide the question at issue," he declared. When advice and suggestions were offered him he rejected them contemptuously, and announced that whenever orders were issued to him he exercised his own judgment as to obedience.

General McClellan's vanity and presumption might have been overlooked by General Scott, but his insulting remarks could not be excused. Their relations reached an acute stage in August, 1861, notwithstanding the President's efforts at reconciliation. Again and again he apologized for and explained away the rudeness of the younger officer towards his superior; and General Scott, realizing the President's embarrassment, begged to be relieved from active command because of his age and infirmities. Perhaps it would have been wiser if the wishes of the aged general had been complied with, for he was now practically helpless, fretful, and forgetful, and his sensitiveness made it necessary to consult him upon every proposition and admit him to every conference. Finally, McClellan's contemptuous indifference, persistent disrespect, and continual disobedience provoked General Scott beyond endurance, and on the last day of October he asked that his name be placed on the list of army officers retired from active service.

"For more than three years," he wrote, "I have been unable from a hurt to mount a horse or to walk more than a few paces at a time and that with much pain. Other and new infirmities, dropsy, and vertigo, admonish me that repose of mind and body are necessary to add a little more to a life already protracted much beyond the usual span of man."
