As to this man Grenfel, I confess I have no sympathy with him; no sympathy for the foreigner who lands in our country when this nation is engaged in the struggle for human right and human liberty, and who takes part in the quarrel against us, and arrays himself on the side of those who are trying to establish tyranny and slavery. I have no sympathy for the man whose sword is unsheathed for hire and not for principle; for whom slavery and despotism have more charms than freedom and liberty. The motive of such a one does not rise even to the dignity of vengeance. As has been said by his counsel, his sword has gleamed in every sun, and has been employed on the side of almost every nationality, and after this he engages in our struggle, and, as testified to by Colonel Moore, desires to raise the black flag against our prisoners; and after men have yielded as prisoners of war, he rides up to one, and stabs him, coward like, in the back. But he is not true to the cause he espouses. When in Washington he went to the Secretary of War and betrays the very people with whom he had been fighting; tells all he knows of the strength, position and designs of the Confederates. He said he proposed to leave immediately for England, but he breaks his faith, proceeds to Canada, and is found among the conspirators, and is now here, charged with these crimes to-day. There is no throb of my heart that beats in unison with such conduct as this. He was a fit instrument to be used in this enterprise. What to him would be the wail of women and little ones? What to him would be the pleadings of old men and unarmed citizens? The delivery of Judge Burnett's argument occupied three and a half hours, after which the Commission adjourned to meet at four o'clock P.M., to deliberate on the findings and sentence. They accordingly met at the hour appointed, and, after mature deliberation, finally recorded their verdict. General Hooker issued General Orders No. 30, April 22, in which he promulgates the finding of the military commission which, for three months past, has been engaged in the trial of the alleged Chicago conspirators. The commission have acquitted Buckner S. Morris and Vincent Marmaduke, and they are to be discharged upon their taking the oath of allegiance. They find Charles Walsh and Richard T. Semmes guilty of all the charges and specifications, and sentence the former to five years' imprisonment at hard labor from the 7th of November last, and the latter to three years' imprisonment at hard labor from the same date, at such place as the commanding general may direct. Gen. Hooker has named the State penitentiary at Columbus, Ohio.
