The Ninth Article of the Impeachment was based upon alleged military changes in the City of Washington whereby the number of troops on duty there was rumored to have been largely increased, with a view to their use in the controversy between the President and Congress, and more especially for the expulsion of Mr. Stanton from the War Office in case of his resistance to the order of the President for his retirement. The wildest rumors of that character prevailed--that Mr. Johnson proposed to throw off all disguise and assume direct military control and the establishment of practically a military dictatorship. Congress had some months previously enacted that all military orders from the President should be issued through the General of the Army--the Congress thereby assuming to practically abrogate a constitutional function of the Chief Executive. There was considerable confidence among the supporters of the impeachment that they would be able to prove these allegations by General Emory, then in local command of the troops and Department of Washington. General Emory was called by the prosecution, and the following was his testimony. Examined by Mr. Butler: Question: Will you have the kindness to state, as nearly as you can what took place then? (Referring to an interview with the President at the Executive Mansion.) Answer: I will try and state the substance of it, but the words I can not undertake to state exactly. The President asked me if I recollected a conversation he had had with me when I first took command of the department. I told him that I recollected the facts of the conversation distinctly.

The President said: "I do not refer to those changes." I replied that if he would state what changes he referred to, or who made the report of the changes, perhaps I could be more, explicit. He said, "I refer to recent changes within a day or two," or something to that effect. I told him I thought I could assure him that no changes had been made; that under a recent order issued for the government of the armies of the United States, founded upon a law of Congress, all orders had to
