The military commission before which he was tried was convened by an order of President Johnson, of August 19th, directing the officers detailed for that purpose to meet as a special military commission on August 20th, for the trial of such prisoners as might be brought before it. The commission convened, and Wirz was arraigned on the charges above mentioned, and pleaded not guilty. At the suggestion of the Judge Advocate, Joseph Holt, he was remanded to prison and the court adjourned. The so-called trial afterward came on, and lasted for three months, but no evidence whatsoever was produced showing the existence of such a conspiracy as had been charged. Wirz was, however, pronounced guilty, and, in accordance with the sentence of the commission, he was executed on November 10, 1865.

On April 4, 1867, Mr. Louis Schade, of Washington, and the attorney for Wirz on the trial, in compliance with the request of Wirz so to do, as soon as the times should be propitious, published a vindication of his character. The following is an extract from this publication:

"On the night previous to the execution of the prisoner, some parties came to the confessor of Wirz (Rev. Father Boyle) and also to me. One of them informed me that a high Cabinet officer wished to assure Wirz that, if he would implicate Jefferson Davis with the atrocities committed at Andersonville, his sentence should be commuted. He (the messenger, whoever he was) requested me to inform Wirz of this. In presence of Father Boyle, I told him next morning what had happened. The Captain simply and quietly replied: 'Mr. Schade, you know that I have always told you that I do not know anything about Jefferson Davis. He had no connection with me as to what was done at Andersonville. If I knew anything of him, I would not become a traitor against him or anybody else to save my life.' Thus ended the attempt to suborn Captain Wirz against Jefferson Davis."

The following is an extract from a letter of Captain C. B. Winder to
Mrs. Davis, dated Eastern Shore of Virginia, January 9, 1867:

"The door of the room which I occupied while in confinement at the Old Capitol Prison, Washington, was immediately opposite Captain Wirz's door—both of which were occasionally open. About two days before Captain Wirz's execution, I saw three or four men pass into his room, and, upon their coming out, Captain Wirz told me that they had given him assurances that his life would be spared and his liberty given to him if he (Wirz) could give any testimony that would reflect upon Mr. Davis or implicate him directly or indirectly with the condition and treatment of prisoners of war, as charged by the United States authorities; that he indignantly spurned these propositions, and assured them that, never having been acquainted with Mr. Davis, either officially, personally, or socially, it was utterly impossible that he should know anything against him, and that the offer of his life, dear as the boon might be, could not purchase him to treason and treachery to the South and his friend."

The following letter is from the Rev. Father F. E. Boyle, of
Washington:

"WASHINGTON, D. C., October 10, 1880.

"Hon. JEFFERSON DAVIS.

"DEAR SIR: . . . I know that, on the evening before the day of the execution of Major Wirz, a man visited me, on the part of a Cabinet officer, to inform me that Major Wirz would be pardoned if he would implicate Jefferson Davis in the cruelties of Andersonville. No names were given by this messenger, and, upon my refusal to take any action in the matter, he went to Mr. Louis Schade, counsel for Major Wirz, with the same purpose and with a like result.

"When I visited Major Wirz the next morning, he told me that the same proposal had been made to him, and had been rejected with scorn. The Major was very indignant, and said that, while he was innocent of the cruel charges for which he was about to suffer death, he would not purchase his liberty by perjury and a crime, such as was made the condition of his freedom. I attended the Major to the scaffold, and he died in the peace of God, and praying for his enemies. I know he was indeed innocent of all the cruel charges on which his life was sworn away, and I was edified by the Christian spirit in which he submitted to his persecutors. Yours very truly,
