And here let us pause to consider one feature of the trial and of the summing up of Judge Bingham, which has not yet been noticed because it deserves special and prominent remark.
It appeared from the testimony on the part of the prosecution, unmistakably, that, during the fall of 1864 and the winter of 1864-5, Booth was brooding over a wild plot for the capture of the President (either on one of his drives, or in the theatre, where the lights were to be turned off), then hurrying off the captive to lower Maryland, thence across the Potomac, and thence to Richmond; thereby to force an exchange of prisoners, if not, possibly, a cessation of the war. It was a plot of the kind to emanate from the disordered brain of a young, spoiled, dissipated and disappointed actor. During this period, Booth made some trifling and miserably inadequate preparations, and endeavored to enlist some of his associates in its execution; and, by his personal ascendency over them, he did in fact entangle, in a more or less vague adhesion to the plot, Arnold, O’Laughlin, Atzerodt, Payne, Herold, John H. Surratt, Lloyd, and, possibly, Dr. Mudd and Weichman.
On the fall of Richmond, and the surrender of Lee, this any-how impracticable scheme was necessarily abandoned. Indeed, the proof showed that Arnold and O’Laughlin had deserted their leader some time before.
It further appeared in the testimony that it was not until after the forced abandonment of this plot and the desertion of most of his adherents, that Booth, plunged as he was into the depths of chagrin and despair because of the collapse of the rebellion, suddenly, as a mere after-thought, the offspring of a spirit of impotent revenge, seized upon the idea of murder, which was not in fact brought to the birth until the afternoon of the fourteenth, when he was first informed of the promised attendance of President Lincoln and General Grant at the theatre. Now, the existence of the plot to capture, although it looked forth from the evidence steadily into their faces, the Judge-Advocates bound themselves not to recognize. In the first place, such a concession would forever demolish the preconceived theory of the Secretary of War, Colonel Baker and the Bureau of Military Justice, that the conspiracy to murder emanated from the Confederate Government through its Canadian agents, by pointing directly to another plot than the one to kill as that in which these agents had been interested. The horrid monster of a widespread, treasonable conspiracy to overthrow the government, which had been conjured up in the imagination of the Secretary of War and then cherished in the secret recesses of the Bureau of Military Justice, would have immediately shrunk into the comparatively simple case of an assassination of the President and an attempted assassination of the Secretary of State, by two worthless villains suddenly seizing opportunity by the forelock to accomplish their murderous purpose. And, in the next place, the concession of such a plot as a fact would go far to establish the innocence of Mrs. Surratt, Arnold, O’Laughlin and Mudd, as well as that of John H. Surratt, by explaining such suspicious circumstances as the frequent rendezvous of Booth, Payne and others at Mrs. Surratt’s house, which practice, as it was proved, ceased altogether on the fall of Richmond and the immediate departure of the son to Canada. To the Judge-Advocates, if not to the Court, any evidence looking towards innocence was most distasteful and unwelcome. They were in no mood to reconcile what they considered the damning proofs of a conspiracy to kill their “beloved Commander-in-Chief” with the innocence of the fettered culprits before them, by admitting a plot to capture, into which nevertheless those same proofs fitted with surprising consistency. Besides, in the eyes of Bingham and Holt, complicity in a plot to capture, although unexecuted, was proof of complicity in the plot to murder, and also of itself deserved death. In this direction, therefore, the Judge-Advocates were mole-eyed. On the contrary, they hailed the slightest indication of guilt with a glow of triumph. In the direction of guilt, they were lynx-eyed.
Consequently, they bent every energy to identify the plot to capture with the plot to kill. They introduced anonymous letters, dropped letters; a letter mailed nearly a month after the assassination directed to J. W. B.; a letter in cipher, purporting to be dated the day after the assassination, addressed to John W. Wise, signed “No Five,” found floating in the water at Morehead City, North Carolina, as late as the first of May; this last, the most flagrant violation and cynical disregard of the law of evidence on record.
They did more. They labored to keep out all reference to the plot to capture. And it was for this reason, that the Judge-Advocates deliberately suppressed the diary found on the body of Booth. Its contents demonstrated the existence of the plot to capture.
Instead of allowing the officer who testified to the articles taken from the dead body of Booth to make a detailed statement in response to one general question as to what they were, the examining counsel shows him first the knife, then the pistols, then the belt and holster, then a file with a cork at one end, then a spur, then the carbine, then the bills of exchange, then the pocket-compass; following the exhibition of every article with the interrogatory, “Did you take this from the corpse of the actor?” But no diary was exhibited or even spoken of, although, as has been mentioned, it was carried by this same officer and Colonel Baker to Secretary Stanton on the night following the capture. That these Judge-Advocates had carefully searched through the diary for items they could use against the prisoners, is shown by their calling one of the proprietors of the “National Intelligencer,” as a witness, to contradict the statement that Booth had left a written article, setting forth the reasons for his crime, for publication in that paper—a statement found only in the diary whose very existence they kept secret.
Therefore, when Judge Bingham came to review the evidence, he utterly refused to recognize in the testimony any such thing as a plot to capture; he shut his eyes to it and obstinately ignored it; he scornfully swept it aside as an absurdity it would be waste of time to combat; and he twisted every circumstance which looked to a connection, however remote, with an abandoned plot to kidnap, into a proof, solid and substantial, of complicity in the plot to murder.
And, therefore, when this same thorough-going advocate, with his two emulous associates, proceeded in secret conclave with the members of the Commission to go over the testimony for the purpose of making up their verdict and sentence, he summarily stifled any hint as to the possibility of a plot to capture; he banished from the minds of the Court, if they ever entertained such a purpose, any attempt to reconcile the circumstantial evidence with the existence of such a plot; and, besides, he held it up to the condemnation of those military men as equally heinous and as deserving the same punishment as the actual assassination.
Thus, the presence of these prosecutors during the deliberations of the Court must have exerted a deadly influence (if any influence were necessary) against the prisoners, and benumbed any impartiality and freedom of judgment which might otherwise have lodged in the members of the Commission.
