On the next day (Thursday, May 11th), Mr. Thomas Ewing, Jr. and Mr. Frederick Stone appeared as counsel for Dr. Mudd, and Mr. Frederick A. Aiken and Mr. John W. Clampitt for Mrs. Surratt; and on the succeeding day (12th), Mr. Frederick Stone appeared for Herold "at the earnest request of his widowed mother and estimable sisters;" General Ewing for Arnold (and on Monday, the 15th, for Spangler); Mr. Walter S. Cox for O'Laughlin, and Mr. William E. Doster for Payne and Atzerodt. By the rules of the Commission no counsel could appear for the prisoners unless he took the "iron-clad oath" or filed evidence of having taken it. So supersensitive was the loyalty of the Court that it could not brook the presence of a "sympathizer with the South," even in such a confidential relation as counsel for accused conspirators in aid of the Rebellion. The demeanor of the Court towards the counsel for the defense, reflecting as in a mirror the humor of the Judge-Advocates, was highly characteristic. Sometimes they were treated with haughty indifference, sometimes with ironical condescension, often with contumely, generally with contempt. Their objections were invariably overruled, unless acceded to by the Judge-Advocate. The Commission could not conceal its secret opinion that they were engaged in a disreputable and disloyal employment. This statement must be somewhat qualified, however, so far as it relates to General Ewing. He was, or had been recently, of equal rank in the army of the Union with the members of the Court. He was a brother-in-law of General Sherman, and he had acquired a high reputation for gallantry and skill, as well as loyalty, during the war. That such a distinguished fellow-soldier should appear to defend the fiendish murderers of their beloved Commander-in-Chief--outlaws they were detailed as a Court to hang--evidently perplexed and disconcerted these military Judges and tended in some degree to curb the over-bearing insolence of the Special Judge-Advocate. Thus, this able lawyer and gallant officer and noble man was enabled to be "the leading spirit of the defense;" and, as we shall see, he wrought the miracle of plucking from the deadly clutches of the Judge-Advocates the lives of every one of the men he defended. But this instance was a most notable exception. As a rule, even the silent presence of the counsel for the accused jarred upon the feelings of the Court, and their vocal interference provoked, at intervals, its outspoken animadversion. A trifling incident will serve to illustrate.
