In a conversation with me shortly after this Mr. Lincoln said, "Well, I suppose our victory at Antietam will condone my offence in reappointing McClellan. If the battle had gone against us poor McClellan (and I too) would be in a bad row of stumps." Had not the tide of success and victory turned in our favor about this time, there is little doubt that Mr. Lincoln would have been deposed and a military dictatorship erected upon the ruins of his administration. The victory at Antietam was, without doubt, the turning point for fame or for downfall in the career of Mr. Lincoln. Between Francis P. Blair and Mr. Lincoln there existed from first to last a confidential relationship as close as that maintained by Mr. Lincoln with any other man. To Mr. Blair he almost habitually revealed himself upon delicate and grave subjects more fully than to any other. When he had conceived an important but difficult plan, he was almost certain, before giving it practical form, to try it by the touchstone of Mr. Blair's fertile and acute mind. Mr. Blair understood Mr. Lincoln's conception of the importance of McClellan to the President and to the country, and, like the President himself, he realized that McClellan's usefulness, unless destroyed by some disaster in the field, could be abridged only by some needless misunderstanding between the two. He knew the stubborn spirit of the Democratic party from long experience in it and with it; and he early foresaw the tremendous influence which would inevitably be brought to bear on McClellan to separate him from Lincoln. It was because he foresaw this that he desired to place nearest to General McClellan in the field some one who, having the complete confidence of both, would form a connecting link which could not be broken. To this end, about the time General Pleasanton was appointed brigadier-general, and assigned to report to General McClellan, Mr. Blair sought a conference with him and said: "You are going to McClellan. You will have confidential relations with him. I like him, and I want him to succeed; but no general can succeed without proper relations with the Administration. Say to him from me that Frank P. Blair, Jr., can be of great service to him. I shall have access to the Administration, and can do much to keep McClellan right. Say to him that he ought to ask for the assignment of Blair to him, and to make him his chief of staff. Now, Pleasanton, when you get down in Virginia, say this to Mac, and telegraph me the result." It was then agreed that the communication should be in cipher. If favorable, "The weather is fair;" if otherwise, "The weather is fair, but portends a storm." Mr. Blair's message was given to McClellan, and General Pleasanton saw that it made an impression; but General McClellan faltered, subject, no doubt, to some of the influences that Mr. Blair had foreseen. After three days' deliberation, the "bad weather" was indicated to Mr. Blair.
