Burr, according to Merry, then alluded to the possibility of the inhabitants of the western parts of the United States joining in this independence movement since Louisiana must always have command over them because of their rivers joining with the Mississippi. Burr as usual threw out hints without definitely committing himself. “It is clear,” commented Merry, “that Mr. Burr (although he has not as yet confided to me the exact nature and extent of his plan) means to endeavor to be the instrument of effecting such a connection.”
Merry went on to quote Burr as saying that for obvious reasons the people of Louisiana would prefer having the protection and assistance of Great Britain to that of France; but that if His Majesty’s Government should not think proper to listen to his overture, application would be made to the Government of France. Burr claimed that the French Government was eager to embrace such an opportunity and that, even while at war with England, it could find means for sending to America the small force that would be needed for the purpose.
As to the military aid from the British that would be required for the enterprise Burr, according to Merry, thought that two or three frigates and the same number of smaller vessels, stationed at the mouth of the Mississippi to prevent its being blockaded by any such force as the United States could send, and to keep open the communications with the sea, was all that would be required.
Then Burr came to the vital matter of cost. Merry said Burr conceived that a “loan” of about £100,000 would be sufficient for the immediate purposes of the enterprise. Burr went even further to suggest a way to prevent any suspicion of His Majesty’s Government being involved in the transaction until the independence of Louisiana had been declared. Such suspicion would be raised if remittances were made from England to the United States or if bills were drawn in this country. Burr knew that a payment of £200,000 was due from the United States to England in the coming July. He proposed that the British Government appropriate part of this sum to his plan. If they would do that, Burr told Merry, he could devise the means to get the money into his possession without its destination being either known or suspected.
Merry gave no intimation of being surprised at this proposal. If the British Government had been as naïve as its minister in Washington, imagine the change in Burr’s declining fortune on finding himself possessed of the equivalent of approximately $500,000 out of the British Treasury and under conditions that would prevent the British Government from confessing its source or protesting any purpose to which Burr might put it.
Shortly after this interview Burr set out for the West. It will be recalled that some careless talk, which gave rise to rumors, alarmed Daniel Clark in New Orleans and caused him to sound a warning to Burr through General Wilkinson. Merry, who by this time imagined that he was a party to the intrigue, also heard the rumors and expressed his anxiety in a letter to Lord Mulgrave who had succeeded Harrowby in the ministry of William Pitt. He wrote: “... I learn that that gentleman [Burr] has commenced his plans in the Western country, and apparently with much success, although it would seem that he or some of his agents have either been indiscreet in their communication, or have been betrayed by some person in whom they considered that they had reason to confide, for the object of his journey has now begun to be noted in the public prints, where it is said that a convention is to be called immediately from the States bordering on the Ohio and the Mississippi for the purpose of forming a separate government.”
There was a more favorable interpretation of the leak which Merry thought worth mentioning. “It is, however, possible,” he said, “that the business may be so advanced as, from the nature of it, to render any further secrecy impossible.” Merry concluded by noting that Burr had been received everywhere with the most marked attention.
When Burr returned from his western trip in November he lost no time in calling on the British Minister. Merry faithfully reported their conversation to Lord Mulgrave in a letter dated November 25. Burr, according to Merry, opened the conversation by stating that he had supposed the British Government disposed to give him assistance. However, continued Burr, the information he had received on this head was not sufficiently explicit to warrant his sending a confidential person to London to make the necessary communication as he had promised to do. He had therefore to content himself by speaking through Merry.
His disappointment at the hesitation of the British Government, Burr told Merry, had given him the deepest concern because his journey through the western country and Louisiana as far as New Orleans, not to speak of a visit to a part of West Florida, had been attended with so much more success than he had even looked for. Everything, he said, was completely prepared in every quarter for the execution of his plan. Therefore he had been induced to enter into an agreement with his associates and friends to return to them in March to commence operations.
Again Burr refrained from entering into details with Merry. He thought enough had been said to start the project and that the rest of the arrangements could be made through authorized persons he recommended to accompany the British ships. These would cruise off the mouth of the Mississippi, commencing April 10 at the latest and continuing there until the commanding officer should receive information from him or from Daniel Clark that Louisiana had declared itself independent.
