When Booth made his escape, it is testified by Colonel Stewart, who pursued him across the stage and out through the same door, that as he approached it some one slammed it shut. Ritterspaugh, who was standing behind the scenes when Booth fired the pistol and fled, saw Booth run down the passage toward the back door, and pursued him; but Booth drew his knife upon him and passed out, slamming the door after him. Ritterspaugh opened it and went through, leaving it open behind him, leaving Spangler inside, and in a position from which he readily could have reached the door. Ritterspaugh also states that very quickly after he had passed through this door he was followed by a large man, the first who followed him, and who was, doubtless, Colonel Stewart. Stewart is very positive that he saw this door slammed; that he himself was constrained to open it, and had some difficulty in opening it. He also testifies that as he approached the door a man stood near enough to have thrown it to with his hand, and this man, the witness believes, was the prisoner Spangler. Ritterspaugh has sworn that he left the door open behind him when he went out, and that he was first followed by the large man, Colonel Stewart. Who slammed that door behind Ritterspaugh? It was not Ritterspaugh; it could not have been Booth, for Ritterspaugh swears that Booth was mounting his horse at the time; and Stewart swears that Booth was upon his horse when he came out. That it was Spangler who slammed the door after Ritterspaugh may not only be inferred from Stewart's testimony, but it is made very clear by his own conduct afterwards upon the return of Ritterspaugh to the stage. The door being then open, and Ritterspaugh being asked which way Booth went, had answered. Ritterspaugh says: "Then I came back on the stage, where I had left Edward Spangler; he hit me on the face with his hand and said, 'Don't say which way he went.' I asked him what he meant by slapping me in the mouth? He said, 'For God's sake, shut up.'"

The testimony of Withers is adroitly handled to throw doubt upon these facts. It cannot avail, for Withers says he was knocked in the scene by Booth, and when he "come to" he got a side view of him. A man knocked down and senseless, on "coming to" might mistake anybody by a side view for Booth.

An attempt has been made by the defense to discredit this testimony of Ritterspaugh, by showing his contradictory statements to Gifford, Garlan, and Lamb, neither of whom do in fact contradict him, but substantially sustain him. None but a guilty man would have met the witness with a blow for stating which way the assassin had gone. A like confession of guilt was made by Spangler when the witness Miles, the same evening, and directly after the assassination, came to the back door, where Spangler was standing with others, and asked Spangler who it was that held the horse, to which Spangler replied: "Hush; don't say anything about it." He confessed his guilt again when he denied to Mary Anderson the fact, proved here beyond all question, that Booth had called him when he came to that door with his horse, using the emphatic words, "No, he did not; he did not call me." The rope comes to bear witness against him, as did the rope which Atzerodt and Herold and John H. Surratt had carried to Surrattsville and deposed there with the carbines.

It is only surprising that the ingenious counsel did not attempt to explain the deposit of the rope at Surrattsville by the same method that he adopted in explanation of the deposit of this rope, some sixty feet long, found in the carpet-sack of Spangler, unaccounted for save by some evidence which tends to show that he may have carried it away from the theatre.

It is not needful to take time in the recapitulation of the evidence, which shows conclusively that David E. Herold was one of these conspirators. His continued association with Booth, with Atzerodt, his visits to Mrs. Surratt's, his attendance at the theatre with Payne, Surratt, and Atzerodt, his connection with Atzerodt on the evening of the murder, riding with him on the street in the direction of and near to the theatre at the hour appointed for the work of assassination, and his final flight and arrest, show that he, in common with all the other parties on trial, and all the parties named upon your record not upon trial, and combined and confederated to kill and murder in the interests of the rebellion, as charged and specified against them.

That this conspiracy was entered into by all these parties, both present and absent, is thus proved by the acts, meetings, declarations, and correspondence of all the parties, beyond any doubt whatever. True it is circumstantial evidence, but the court will remember the rule before recited, that circumstances cannot lie; that they are held sufficient in every court where justice is judicially administered to establish the fact of a conspiracy. I shall take no further notice of the remark made by the learned counsel who opens for the defense, and which has been followed by several of his associates, that under the Constitution it requires two witnesses to prove the overt act of high treason, than to say, this is not a charge of high treason, but of a treasonable conspiracy, in aid of a rebellion, with intent to kill and murder the executive officer of the United States, and commander of its armies, and of the murder of the President in pursuance of that conspiracy, and with the intent laid, etc. Neither by the Constitution, nor by the rules of the common law, is any fact connected with this allegation required to be established by the testimony of more than one witness. I might say, however, that every substantive averment against each of the parties named upon this record has been established by the testimony of more than one witness.

That the several accused did enter into this conspiracy with John Wilkes Booth and John H. Surratt to murder the officers of this government named upon the record, in pursuance of the wishes of their employers and instigators in Richmond and Canada, and with intent thereby to aid the existing rebellion and subvert the Constitution and laws of the United States, as alleged, is no longer an open question.

The intent as laid was expressly declared by Sanders in the meeting of the conspirators at Montreal in February last, by Booth in Virginia and New York, and by Thompson to Conover and Montgomery; but if there were no testimony directly upon this point, the law would presume the intent, for the reason that such was the natural and necessary tendency and manifest design of the act itself.

The learned gentleman (Mr. Johnson) says the government has survived the assassination of the President, and thereby would have you infer that this conspiracy was not entered into and attempted to be executed with the intent laid. With as much show of reason it might be said that because the government of the United States has survived this unmatched rebellion, it therefore results that the rebel conspirators waged war upon the government with no purpose or intent thereby to subvert it. By the law we have seen that, without any direct evidence of previous combination and agreement between these parties, the conspiracy might be established by evidence of the acts of the prisoners, or of any others with whom they co-operated, concurring in the execution of the common design.—Roscoe, 416.

Was there co-operation between the several accused in the execution of this conspiracy? That there was is as clearly established by the testimony as is the fact that Abraham Lincoln was killed and murdered by John Wilkes Booth. The evidence shows that all of the accused, save Mudd and Arnold, were in Washington on the 14th of April, the day of the assassination, together with John Wilkes Booth and John H. Surratt; that on that day Booth had a secret interview with the prisoner, Mary E. Surratt; that immediately thereafter she went to Surrattsville to perform her part of the preparation necessary to the successful execution of the conspiracy, and did make that preparation; that John H. Surratt had arrived here from Canada, notifying the parties that the price to be paid for this great crime had been provided for, at least in part, by the deposit receipts of April 6th for $180,000, procured by Thompson of the Ontario Bank, Montreal, Canada; that he was also prepared to keep watch, or strike a blow, and ready for the contemplated flight; that Atzerodt, on the afternoon of that day, was seeking to obtain a horse, the better to secure his own safety by flight, after he should have performed the task which he had voluntarily undertaken by contract in the conspiracy—the murder of Andrew Johnson, then Vice-President of the United States; that he did procure a horse for that purpose at Naylor's, and was seen about nine o'clock in the evening to ride to the Kirkwood House, where the Vice-President then was, dismount and enter. At a previous hour Booth was in the Kirkwood House, and left his card, now in evidence, doubtless intended to be sent to the room of the Vice-President, and which was in these words: "Don't wish to disturb you. Are you at home? J. Wilkes Booth." Atzerodt, when he made application at Brooks's in the afternoon for the horse, said to Wiechmann, who was there, he was going to ride in the country, and that "he was going to get a horse and send for Payne." He did get a horse for Payne, as well as for himself; for it is proven that on the 12th he was seen in Washington riding the horse which had been procured by Booth, in company with Mudd, last November, from Gardner. A similar horse was tied before the door of Mr. Seward on the night of the murder, was captured after the flight of Payne, who was seen to ride away, and which horse is now identified as the Gardner horse. Booth also procured a horse on the same day, took it to his stable in the rear of the theatre, where he had an interview with Spangler, and where he concealed it. Herold, too, obtained a horse in the afternoon, and was seen between nine and ten o'clock riding with Atzerodt down the Avenue from the Treasury, then up Fourteenth and down F Street, passing close by Ford's Theatre.
