In the fateful summer of 1806 when Colonel Burr departed from the East “never to return,” he was joined in the western country by the Alstons—Theodosia, Joseph, and little Aaron. The Alstons were for a time guests of the Blennerhassetts on their island in the Ohio River. There Theodosia won the undying affection of Margaret Blennerhassett and the admiration of her husband Harman. Although the Alstons were not present at the time of the alleged “overt act,” their visit a short time before served to increase the public’s suspicion of Alston’s implication in the plot. His name, it will be recalled, was mentioned in Burr’s letter to Wilkinson of July 29.

The circumstance caused Alston intense embarrassment. He had become accustomed to the annoyance of receiving requests for loans from his father-in-law, but that was a small matter compared with the Colonel’s use of his name in so damaging a document as the cipher letter to Wilkinson. In his perplexity Alston unburdened himself in a letter to his friend Charles Pinckney, then Governor of South Carolina.

“I have,” he said, “received and read the President’s message with deep mortification and concern; but the letter annexed to it, stated to be a communication in cypher from Col. Burr to Gen. Wilkinson, exacted my unfeigned astonishment.

“I solemnly avow that, when that letter was written, I had never heard, directly or indirectly from Col. Burr or any other person, of the meditated attack on that place, or any other part of the United States, than I have at this moment to suspect that our militia will be forthwith ordered on an expedition against Gibraltar. On the other hand, I had long had strong grounds for believing that Col. Burr was engaged by other objects, of a very different nature from those attributed to him, and which I confess the best sentiments of my heart approved. I need not add that those objects involved not the interests of my country.

“Without adverting to that integrity of principle, which even my enemies I trust have allowed me, can it be supposed that a man situated as I am—descended from a family which has never known dishonor, happy in the affection and esteem of a large number of relations and friends, possessed of ample fortune, and standing high in the confidence of his fellow-citizens—could harbor for an instant, a thought injurious to the country which was the scene of those blessings?

“Whatever may be thought of the heart of Mr. Burr, his talents are great beyond question, and to reconcile with such talents the chimerical project of dismembering the union, or wresting from it any part of its territory is difficult indeed.... He imagined perhaps—which, by the way, he had no right to do—that his influence would be sufficiently great to induce my assent and thought, therefore he might as well consider it already obtained; or which is more probable, he might have imagined that by the apparent concern of a number of persons from different States, a stronger impression would be made on his correspondent.”

Alston’s letter, of course, soon became public property. Could a young man have found himself in a more embarrassing position? His good name had been dangerously compromised. Alston rightly felt he should clear himself of the suspicions which mention of his name in the letter naturally aroused. But how could he do that without casting reflections on his father-in-law? And how could he cast reflections on his father-in-law without showing disloyalty to Theodosia?

The effort was not altogether successful. The first paragraph of the letter was favorable to the Colonel in that it repudiated any idea that he was contemplating an attack on New Orleans or on any other part of the United States. It was as much a defense of the Colonel as it was of himself. But the closing passages did not express sentiments which were flattering or with which Colonel Burr could be greatly pleased.

The distinction made between Burr’s “heart” and his “talents” intimated that while the moral issue involved in a conspiracy against the Government would not have restrained him, his intelligence would have told him the idea of dividing the Union was impractical. Then Alston had gone on to state frankly that Burr had no right to use his name without his consent and to suggest that it had been only a cheap trick to impress Wilkinson. It definitely was not the sort of letter to help preserve peace in the family.

On the other hand, when the Government was stretching forth its mighty hand to grasp Burr certainly was no time for discord between him and his son-in-law. It was reported in some quarters that when Burr heard about the letter there was a scene between the two men. If so, wisdom and necessity triumphed over ill temper. Whatever their innermost feelings may have been, Burr and Alston presented to the world a solid front.
