Assassination of Lincoln: a History of the Great Conspiracy / Trial of the Conspirators by a Military Commission, and a Review of the Trial of John H. Surratt

by T. M. Harris

An existing rebellion is alleged and not denied. It is charged that in aid of this existing rebellion a conspiracy was entered into by the accused, incited and instigated thereto by the chiefs of this rebellion, to kill and murder the executive officers of the government and the commander of the armies of the United States, and that this conspiracy was partly executed by the murder of Abraham Lincoln, and by a murderous assault upon the Secretary of State; and counsel reply, by elaborate argument, that although the facts be as charged, though the conspirators be numerous and at large, able and eager to complete the horrid work of assassination already begun within your military encampment, yet the successor of your murdered President is a usurper if he attempts by military force and martial law, as Commander-in-Chief, to prevent the consummation of this traitorous conspiracy in aid of this treasonable rebellion. The civil courts, say the counsel, are open in the District. I answer, they are closed throughout half the republic, and were only open in this District on the day of this confederation and conspiracy, on the day of the traitorous assassination of your President, and are only open at this hour by force of the bayonet. Does any man suppose that if the military forces which garrison the intrenchments of your capital, fifty thousand strong, were all withdrawn, the rebel bands who this day infest the mountain passes in your vicinity would allow this court, or any court, to remain open in this District for the trial of these their confederates, or would permit your executive officers to discharge the trust committed to them, for twenty-four hours?

At the time this conspiracy was entered into, and when this court was convened and entered upon this trial, the country was in a state of civil war. An army of insurrectionists have, since this trial begun, shed the blood of Union soldiers in battle. The conspirator, by whose hand his co-conspirators, whether present or absent, jointly murdered the President on the 14th of last April, could not be and was not arrested upon civil process, but was pursued by the military power of the government, captured, and slain. Was this an act of usurpation?—a violation of the right guaranteed to that fleeing assassin by the very Constitution against which and for the subversion of which he had conspired and murdered the President? Who in all this land is bold enough or base enough to assert it?

I would be glad to know by what law the President, by a military force, acting only upon his military orders, is justified in pursuing, arresting, and killing one of these conspirators, and is condemned for arresting in like manner, and by his order subjecting to trial, according to the laws of war, any or all of the other parties to this same damnable conspiracy and crime, by a military tribunal of justice—a tribunal, I may be pardoned for saying, whose integrity and impartiality are above suspicion, and pass unchallenged even by the accused themselves.

The argument against the jurisdiction of this court rests upon the assumption that even in time of insurrection and civil war no crimes are cognizable and punishable by military commission or court-martial, save crimes committed in the military or naval service of the United States, or in the militia of the several states when called into the actual service of the United States. But that is not all the argument: it affirms that under this plea to the jurisdiction the accused have the right to demand that this court shall decide that it is not a judicial tribunal and has no legal existence.

This is a most extraordinary proposition—that the President, under the Constitution and laws of the United States, was not only not authorized, but absolutely forbidden, to constitute this court for the trial of the accused, and, therefore, the act of the President is void, and the gentlemen who compose the tribunal without judicial authority or power, and are not in fact or in law a court.

That I do not misstate what is claimed and attempted to be established on behalf of the accused, I ask the attention of the court to the following as the gentleman's (Mr. Johnson's) propositions:—

That Congress has not authorized, and, under the Constitution, cannot authorize the appointment of this commission.

That this commission has, "as a court, no legal existence or authority," because the President, who alone appointed the commission, has no such power.

That his act "is a mere nullity—the usurpation of a power not vested in the Executive, and conferring no authority upon you."

We have had no common exhibition of law learning in this defence, prepared by a Senator of the United States; but with all his experience, and all his learning and acknowledged ability, he has failed, utterly failed, to show how a tribunal constituted and sworn, as this has been, to duly try and determine the charge and specification against the accused, and by its commission not authorized to hear or determine any other issues whatever, can rightfully entertain, or can by any possibility pass upon, the proposition presented by this argument of the gentleman for its consideration.
