In the beginning Mr. Chase was a very strong supporter of General McClellan and frequently called the attention of the latter to his obligations to him. "The country was indebted to me," he wrote McClellan, "in some considerable degree for the change of your commission from Ohio into a commission of major-general of the army of the Union;" and he wrote a friend the good news, "McClellan is Commander-in-Chief! let us thank God and take courage!" but this was his habit. He invariably worshipped the rising sun, and was usually one of the first to turn his back upon old friends when they met with misfortunes. He usually cultivated the closest relations with those generals who had grievances against the administration. His correspondence and his diary, as published by his chosen biographer, are full of caustic and unkind criticisms of his chief. He received many letters containing violent abuse of the President and his colleagues in the government, and neither defended them nor rebuked the writers. He records in his diary a conversation with an officer who, meeting him, the Secretary of the Treasury, for the first time, was rude enough to utter a gross insult directed at the President. In his comments Mr. Chase seems to approve the remarks, and describes the President's assailant as "well read and extremely intelligent." But Mr. Chase never defended his colleagues when they were attacked. In reply to a violent criticism from an enemy of the administration, he wrote, "I am not responsible for the management of the war and have no voice in it, except that I am not forbidden to make suggestions, and do so now and then when I can't help it."

He soon lost his confidence in and admiration for McClellan, however, and in his criticisms concerning his dilatory tactics was the most bitter of all the Cabinet. He once drew up a paper, which he induced several of his colleagues to sign, demanding McClellan's removal. He continually offered advice and suggestions, and when they were not accepted he usually took the trouble to record his resentment in his diary or to express it in vigorous terms in a letter to some friend.

Chase was in favor of the unconditional emancipation of the slaves, and when the President laid before the Cabinet the Emancipation Proclamation he writes in his diary, "I said that I should give to such a measure my cordial support, but I should prefer that no expression on the subject of compensation should be made, and I thought that the measure of emancipation could be better and more quickly accomplished by allowing generals to organize and arm the slaves and by directing the commanders of departments to proclaim emancipation within their districts as soon as practicable. But I regarded this as so much better than inaction on the subject that I could give it my entire support."

The President was not unaware of the disposition of Mr. Seward to criticise himself and the members of his Cabinet, but placed so high a value upon his ability and his importance to the government that he treated him with the same patience that he did Mr. Stanton and others who were critical and petulant concerning his deliberation and other peculiarities. The extent to which this forbearance was exercised may be illustrated by a note addressed to the President by his Secretary of the Treasury, April 25, 1861, in which the latter was guilty of such bad taste and impertinence that Lincoln would have been justified in asking his instant resignation. Mr. Chase held the President practically responsible for the demoralized condition of affairs in the country and for all that had happened before his inauguration as well as since, and said, "Let me beg of you to remember that the disunionists have anticipated us in everything, and that as yet we have accomplished nothing but the destruction of our own property. Let me beg of you to remember also that it has been a darling object with the disunionists to secure the passage of a secession ordinance by Maryland.... Save us from this new humiliation. You alone can give the word."

Mr. Chase was in consultation with the President daily, he had been consulted about every situation and movement, he was quite as familiar with what had been done and what was intended as the President himself, and the reasons which prompted him to address his chief in such a manner can only be conjectured. It is believed that he was prompted to do so by one of the many hostile critics of the administration, and wrote the letter without realizing its tone and impertinence. But Lincoln received it with his usual complacency, made no complaint to any one about it, and calmly filed it away among his other correspondence.

Like Mr. Seward, he went into the Cabinet with the opinion that the President was incapable and inexperienced, and that it was his duty to support and assist him in the management of the government; but, unlike Mr. Seward, he was never able to rid himself of a sense of his own superiority. He had an honest conviction that he was more competent and would make a much better President himself, and that if his advice were accepted and his suggestions carried out, the war would be brought to a close much sooner than otherwise. He lacked confidence in his colleagues also and never lost an opportunity to express it. He considered himself their superior in zeal, ability, and devotion to the general welfare. He imagined that every disaster which occurred in the field was due to the refusal of the President and the Secretary of War to carry out the plans he suggested, and that every victory could be directly attributed to his wise counsel. This was not known at the time. Had it been, the people of the country would have been less charitable towards Mr. Chase. His egotism, jealousy, contempt, and hostility towards Lincoln and his fellow-members of the Cabinet were not fully disclosed until the publication of his biography, which contained extracts from his diary and copies of his voluminous correspondence.

The President would not allow the conduct or the disposition of his Secretary of the Treasury to make the slightest difference in his treatment of that official or to affect the policy of his administration, for in his management of the finances, without previous experience or preparation, Mr. Chase had shown genius equal to that of Alexander Hamilton, unswerving integrity, and untiring industry. So highly did Lincoln esteem his public services in this respect that he would have forgiven him anything; and Mr. Chase not only had his constant support, but he was less interfered with in the administration of his department than any other member of the Cabinet.

Mr. Chase began a serious and systematic canvass for the Presidential nomination as early as the fall of 1863, and although he continued to delude himself and assure his friends that he was indifferent to advancement and anxious only for the public good, he found plenty of leisure in the midst of his arduous duties and immense responsibilities to write hundreds of letters to friends in different parts of the Union pointing out the mistakes of the President and leaving the irresistible conclusion that he was the only man capable of saving the country. Many of these letters are published in his biography, and it is inexplicable that he preserved the documentary evidence of his treachery, and even more remarkable that his family thus exposed him to public censure and contempt.

Although Lincoln had the full confidence of the loyal people of the North, many disappointed politicians and other citizens in different parts of the country were dissatisfied with his management of affairs. The critics naturally gravitated together and sought to organize a movement to prevent his renomination. They found it difficult to contend against the popularity of the President, and looked among the discordant elements for a standard-bearer. Neither in Congress nor in the army was there any one who was willing to undertake the hopeless task until some of the leaders consulted Mr. Chase and, to their surprise, found him so indiscreet and disloyal as to encourage their opposition to the administration of which he was a member, and so foolish as to believe that he was strong enough to lead them to victory.

Mr. Chase fell willingly into the trap, although he continued to protest his loyalty and attachment to Lincoln. His only excuse was that the President's intellect and capacity for government were inferior to his own, and in its great emergency his beloved country needed the strongest man. He wrote his son-in-law, Governor Sprague, of Rhode Island, "If I were controlled by merely personal sentiments I would prefer the re-election of Mr. Lincoln to that of any other man, but I think a man of different qualities from those the President has will be needed for the next four years."
