The gentleman from Massachusetts has relied on the conversations, confessions, and conduct of Mr. Smith to prove his guilt, but he does not take the whole conversation and confession together; and it is a rule of law, always admitted, and never to be departed from, that when the confession of the party is taken, the whole must be taken together; and not to make out proof of guilt, by selecting different detached parts, leaving out other parts that go to explain what otherwise might appear criminal. A strict adherence to this rule will leave little of evidence, or even ground of suspicion of guilt in this case. If all Mr. Smith’s conversations and confessions are taken together, there can remain little doubt of his innocence.

The first circumstance in Mr. Smith’s conduct which is laid hold on, and on which the gentleman from Massachusetts has built his argument to establish his guilt, is, that Mr. Smith has confessed that in September, 1806, he gave Aaron Burr a hospitable reception under his roof, for four or five days; that he afterwards saw him again at Cincinnati and in Kentucky. What was there suspicious in all this? Who was Aaron Burr? And what was the situation of Mr. Smith in relation to him, that extending to him the rights of hospitality should excite suspicion, and fix the imputation of crime? Aaron Burr was a man who had stood high in the confidence of the people of the United States—a man who had been associated with the present Chief Magistrate, and had received an equal number of the votes of the electors for President—a man who had been by the voice of his country placed in the second office in the nation—a man who for four years filled the chair you now occupy, and presided over this Senate with impartiality and dignity; and in a manner to command universal approbation. So great was the ascendency which he had acquired in this body, that towards the close of his term of service, a bill was passed granting to him for life the privilege of sending and receiving letters and packets through the mail free of postage, a privilege which had never been extended to any but a President of the United States and Mrs. Washington. So great was the confidence of a majority of the Senate in Aaron Burr, as to produce an unusual zeal, no doubt a laudable zeal, for passing the bill. It was pressed in an unusual manner; and we were called to a decision when he was himself in the chair; he who could almost look down opposition. Under such circumstances it was painful to oppose the bill; and nothing but a strong sense of duty could have impelled any one to make opposition. The yeas and nays on the Journal[53] will show how great a portion of the Senate, of which number was Mr. Smith, had so high a confidence in Mr. Burr. At that time I had no more suspicion than the majority of Colonel Burr’s having any treasonable designs; though in opposition to the bill, I did state it as a possible case, that a Vice President, ambitious of rising to the first office in the nation, and meeting with disappointment, might become disaffected, and engage in treasonable plots to overturn the Government, and avail himself of his privilege and the mail to circulate his treason into every corner of the Union. The bill was arrested in the House of Representatives.

The Senate also adopted the following:

Resolved, unanimously, That the thanks of the Senate be presented to Aaron Burr, in testimony of the impartiality, dignity, and ability with which he has presided over their deliberations; and of their entire approbation of his conduct, in the discharge of the arduous and important duties assigned him as President of the Senate.”

I was happy on this occasion to unite in what I considered a just tribute of applause for his conduct as President of the Senate.

This was the close of Aaron Burr’s political career; this was the last public office he sustained in the nation, and from that time, till Mr. S. received the pencilled note asking for the hospitality of his house for a few days, it was not publicly known that he had done any thing to take off the impression which his official conduct as Vice President, and those public acts of the Senate, had made. Under these circumstances, and considering the intimacy and friendship which had been contracted while they were associated in the same political body, the Senate of the United States, what could Mr. Smith do? What did his early impressions, all the habits of his life, and the honorable feelings and sentiments of a gentleman, imperiously demand of him to do? The answer will be anticipated; he could no otherwise than extend to him the rights of hospitality, receive and treat him as a gentleman. Had he been an entire stranger he could not have done otherwise, without being considered as having disgraced his native State, for he was born in Virginia, so famed for hospitality, not only to friends, but to strangers. Had Mr. S. done otherwise than he did, would he not have been disowned as unworthy to be called a Virginian? This act of hospitality and politeness is now considered as a crime, which is to fix indelible disgrace on Mr. S. and his family.

The next thing relied on is, that Mr. S. being informed of the projects and schemes of Mr. Burr, concealed them. The gentleman from Massachusetts has told us that, if Mr. S. had come forward and testified before the grand jury of Kentucky, Burr would have been convicted, and his treasonable plot, which has done so much mischief, arrested. The disclosure which Mr. S. states to have been made to him, (and there is no proof on the subject but what comes from himself) is as follows—viz: Colonel Burr said to him, “Mr. Smith, my object in a few months will be disclosed; you will not find it dishonorable or inimical to this Government. I feel superior to the mean artifices which are ascribed to me; calumniators I do not notice, for as fast as you put one down, another will rise up. This much I will venture to tell you, if there should be war between the United States and Spain, I shall head a corps of volunteers, and be the first to march into the Mexican provinces; if peace should be preserved, which I do not expect, I shall settle my Washita lands, and make society as pleasant about me as possible.” Now I ask, Mr. President, was there any thing criminal, was there any thing unlawful in all this? Was there any thing to excite suspicion that Aaron Burr was engaged in a treasonable plot to sever the Union, or invade the territory of a friendly power, in amity with the United States? Was it not, on the contrary, expressly said not to be dishonorable or inimical to the Government? Was there any reason to suppose our Government would not, in the event of a war with Spain, accept the services of a corps of volunteers; when the policy seems to have been to rely on volunteers; and laws have frequently passed calling for, and authorizing the employment of such force? The evidence of Mr. S., had he appeared before the grand jury, instead of criminating Colonel Burr, must have operated in his favor; for to have headed a corps of volunteers under such circumstances would have been laudable. Has Mr. S. ever manifested any unwillingness to disclose what he knew of Burr’s projects? On the contrary, has he not always done it freely, when there was a fit occasion, not only to his friends but the officers of Government?

But the gentleman from Massachusetts has compared the case of Mr. Smith with that of Commodore Truxton, and stated that upon Burr’s disclosing his plans to the latter, he was asked this all-important question—“Is the Executive of the United States privy to or concerned in the project?” This, says he, ought to have been the conduct of Mr. Smith; this would have been his conduct if he had been an innocent and an honest man. I little thought that Commodore Truxton’s deposition would have been resorted to in this case; a deposition which had not been read, a deposition not taken on the trial in the presence of Mr. Smith, nor in any way relating to his case. It must be an uncommon zeal that could have induced any one, possessing the legal knowledge of the gentleman from Massachusetts, to have resorted to that as evidence. But, sir, the answer to this is plain. Mr. Burr did not go as far with Mr. Smith as with Commodore Truxton, otherwise Mr. Smith would probably have asked him the same question. But so much reliance having been had on Commodore Truxton’s deposition to prove Mr. Smith’s guilt, on the score of omissions, as well as of what he has done, I must be permitted to read a part of that deposition: it is in these words, viz:

“About the beginning of the winter of 1805-6, Colonel Burr returned from the Western country and came to Philadelphia. He frequently in conversation mentioned to me certain speculations in Western lands. These conversations were uninteresting to me, and I did not pay much attention to them. Colonel Burr requested me to get the Navy of the United States out of my head, as he had something in view, both honorable and profitable, which he wished to propose to me. I considered this as nothing more than a desire to get me interested in land speculations. These conversations were frequently repeated; and some time in the month of July, 1806, Colonel Burr observed that he wished to see me unwedded from the Navy of the United States, and not to think any more of those men at Washington. He observed that he wished to see or to make me (I do not recollect which) admiral; for he contemplated an expedition into Mexico, in the event of a war with Spain, which he thought inevitable. He asked me if the Havana could not be easily taken in the event of a war. I told him that it would require the co-operation of a naval force. Mr. Burr observed, that might be obtained. He pursued the inquiry as to Carthagena and La Vera Cruz; what personal knowledge I had of those places, and what would be the best mode of attacking by sea and land. I gave my opinion very freely. Mr. Burr then asked me, if I would take the command of a naval expedition. I asked him if the Executive of the United States was privy to or concerned in the project. He answered me emphatically, that they were not. I asked him that question because the Executive had been charged with a knowledge of Miranda’s expedition. I told Colonel Burr that I would have nothing to do with it; that Miranda’s project had been intimated to me, and that I had declined any agency in those affairs. Mr. Burr observed that, in the event of a war, he intended to establish an independent Government in Mexico; that Wilkinson, the Army, and many officers of the Navy, would join. I replied, that I could not see how any of the officers of the United States could join. He said that Gen. Wilkinson had projected the expedition, and that he himself had matured it; that many greater men than Wilkinson were concerned (or would join); and thousands to the westward.”

Mr. President, notwithstanding Colonel Burr had gone much farther in communicating his plans and projects to Commodore Truxton than he had done to Mr. Smith, and notwithstanding those insinuations of weaning him from the Navy, forgetting those men at Washington, &c.,—which must have excited suspicion in the mind of a man of Commodore Truxton’s discernment, that Colonel Burr’s project was unlawful, and not known to or approved by the Government—yet Commodore Truxton, in whose honor and integrity I have the highest confidence, did not put the question which the gentleman from Massachusetts relies on so much, and approves so highly, as evincing his integrity; and for not asking which Mr. Smith is to be suspected of a participation in guilt. It was when Colonel Burr asked Commodore Truxton directly if he would take the command of a naval expedition, and not till then, that he put the question. Had Colonel Burr asked Mr. Smith to engage supplies of provisions, gunboats, arms or men, for his expedition, then, and not till then, could it be expected that Mr. Smith should have asked such a question; so far from saying any thing to excite Mr. Smith’s suspicions, Colonel Burr had expressly declared his object was not dishonorable or inimical to this Government. That Commodore Truxton was dissatisfied with the Administration appears by his answer to a question of Mr. McRae in the same deposition, viz: “Were the remarks which he made on your relation to the Navy, calculated to fill your bosom with resentment against the Government? A. My bosom was already full enough, but certainly Colonel Burr spoke in concert with my feelings.”
