But Wilkinson declared in his affidavit that Swartwout had also told him that "this territory would be revolutionized where the people were ready to join them, and that there would be some seizing, he supposed at New Orleans."[946] If this meant that the Government in any American territory was to be revolutionized by force, "although merely as a ... means of executing some greater projects, the design was unquestionably treasonable," said Marshall; "and any assemblage of men for that purpose would amount to a levying of war." It was, then, of first importance to discover the true meaning of the youthful and indiscreet messenger.

For the third time the court divided. "Some of the judges," Marshall explained, suppose that these words of Swartwout "refer to the territory against which the expedition was intended; others to that in which the conversation was held. Some consider the words, if even applicable to a territory of the United States, as alluding to a revolution to be effected by the people, rather than by the party conducted by Col. Burr."

Swartwout's statement, as given in Wilkinson's affidavit, that Burr was assembling thousands of armed men to attack Mexico, did not prove that Burr had gathered an army to make war on the United States.[947] If the latter were Burr's purpose, it was not necessary that the entire host should have met at one spot; if detachments had actually formed and were marching to the place of rendezvous, treason had been committed. Following his tedious habit of repeating over and over again, often in identical language, statements already clearly made, Marshall for the fourth time asserted that there must be "unequivocal evidence" of "an actual assemblage."

The mere fact that Burr "was enlisting men in his service ... would not amount to levying war." That Swartwout meant only this, said Marshall, was "sufficiently apparent." If seven thousand men had actually come together in one body, every one would know about it; and surely, observed Marshall, "some evidence of such an assembling would have been laid before the court."

Burr's intention to do certain "seizing at New Orleans" did not amount to levying war from anything that could be inferred from Swartwout's statement. It only "indicated a design to rob." Having thus examined all the testimony before the court, Marshall announced the opinion of the majority of the Justices that there was not "sufficient evidence of his [Swartwout's] levying war against the United States to justify his commitment on the charge of treason."[948]

The testimony against Bollmann was, if possible, still weaker. There was, indeed, "no evidence to support a charge of treason" against him. Whoever believed the assertions in Wilkinson's affidavit could not doubt that both Bollmann and Swartwout "were engaged in a most culpable enterprise against the dominions of a power at peace with the United States"; but it was apparent that "no part of this crime was committed in the District of Columbia." They could not, therefore, be tried in that District.

Upon that point the court was at last unanimous. The accused men could have been tried in New Orleans—"there existed a tribunal in that city," sarcastically observed Marshall; but to say that citizens might be seized by military power in the jurisdiction where the alleged crime was committed and thereafter tried "in any place which the general might select, and to which he might direct them to be carried," was not to be thought of—such a thing "would be extremely dangerous." So the long-suffering Bollmann and Swartwout were discharged.[949]

Thus, by three different courts, five of the "conspirators" had successively been released. In the case of Ogden, there was no proof; of Alexander, no proof; of Adair, no proof; of Bollmann and Swartwout, no proof. And the Judges had dared to set free the accused men—had refused to consign them to prison, despite public opinion and the desire of the Administration. Could anything be more undemocratic, more reprehensible? The Supreme Court, especially, should be rebuked.

On learning of that tribunal's action, Giles adjourned the meeting of his committee on the treason bill in order to secure immediately a copy of Marshall's opinion. In a true Virginian rage, Giles threatened to offer an amendment to the Constitution "taking away all jurisdiction of the Supreme Court in criminal cases." There was talk of impeaching every occupant of the Supreme Bench.[950]

More news had now reached Washington concerning the outrages committed at New Orleans; and on the day that the attorneys for Bollmann and Swartwout applied to the Supreme Court for writs of habeas corpus, James M. Broom of Delaware rose in the House, and introduced a resolution "to make further provision for securing the privilege of the writ of habeas corpus to persons in custody under or by color of the authority of the United States."[951] While the cases were being argued in the Supreme Court and the divided Judges were wrangling over the disputed points, a violent debate sprang up in the House over Broom's resolution. "If, upon every alarm of conspiracy," said Broom, "our rights of personal liberty are to be entrusted to the keeping of a military commander, we may prepare to take our leave of them forever."[952] All day the debate continued; on the next day, February 18, while Marshall was delivering his opinion that the Supreme Court had jurisdiction of the application of Bollmann and Swartwout, the controversy in the House was renewed.
