"We shall prove to your entire satisfaction, by competent and credible witnesses, that at that time the prisoner at the bar was then present, aiding and abetting that murder; and that at ten minutes past ten o'clock that night he was in front of that theatre in company with Booth. You shall hear what he then said and did. You shall know that his cool and calculating malice was the director of the bullet that pierced the brain of the President and the knife that fell upon the venerable Secretary of State. You shall know that the prisoner at the bar was the contriver of that villainy, and that from the presence of the prisoner, Booth, drunk with theatric passion and traitorous hate, rushed directly to the execution of their mutual will. We shall further prove to you that their companionship upon that occasion was not an accidental or unexpected one, but that the butchery that ensued was the ripe result of a long premeditated plot, in which the prisoner was the chief conspirator. It will be proved to you that he is a traitor to the government that protected him; a spy in the employ of the enemies of his country in the years 1864 and 1865; passed repeatedly from Richmond to Washington, from Washington to Canada, weaving the web of his nefarious scheme, plotting the overthrow of this government, the defeat of its armies, and the slaughter of his countrymen; and as showing the venom of his intent,--as showing a mind insensible to every moral obligation and fatally bent on mischief,--we shall prove his gleeful boasts that during these journeys he had shot down in cold blood, weak and unarmed Union soldiers, fleeing from rebel prisons. It will be proved to you that he made his home in this city the rendezvous for the tools and agents in what he called his "bloody work," and that his hand deposited at Surrattsville, in a convenient place, the very weapons obtained by Booth while escaping, one of which fell or was wrenched from Booth's death grip, at the moment of his capture. "While in Montreal, Canada, where he had gone from Richmond, on the 10th of April, on the Monday before the assassination, Surratt received a summons from his co-conspirator, Booth, requiring his immediate presence in this city. In obedience to that pre-concerted signal, he at once left Canada, and arrived here on the 14th. By numerous, I had almost said a multitude, of witnesses, we shall make the proof to be as clear as the noonday sun, and as convincing as the axioms of truth, that he was here during the day of that fatal Friday, as well as present at the theatre at night, as I have before stated. We shall show him to you on Pennsylvania Avenue, booted and spurred, awaiting the arrival of the fatal moment. "We shall show him in conference with Herold in the evening; we shall show him purchasing a contrivance for disguise an hour or two before the murder.
