The diplomatic Lafitte, having finished for a time his negotiations with the British, lost no time in communicating with the American authorities.  He sent to Governor Claiborne, of Louisiana, all the documents he had received from Captain Lockyer, and wrote him a letter in which he told him everything that had happened, and thus gave to the United States the first authentic information of the proposed attack upon Mobile and New Orleans.  He then told the Governor that he had no intention of fighting against the country he had adopted; that he was perfectly willing and anxious to aid her in every manner possible, and that he and his followers would gladly join the United States against the British, asking nothing in return except that all proceedings against Barrataria should be abandoned, that amnesty should be given to him and his men, that his brother should be released from prison, and that an act of oblivion should be passed by which the deeds of the smugglers of Barrataria should be condoned and forgotten.

Furthermore, he said that if the United States government did not accede to his proposition, he would immediately depart from Barrataria with all his men; for no matter what loss such a proceeding might prove to him he would not remain in a place where he might be forced to act against the United States.  Lafitte also wrote to a member of the Louisiana Legislature, and his letters were well calculated to produce a very good effect in his favor.

The Governor immediately called a council, and submitted the papers and letters received from Lafitte.  When these had been read, two points were considered by the council, the first being that the letters and proclamations from the British might be forgeries concocted by Lafitte for the purpose of averting the punishment which was threatened by the United States; and the second, whether or not it would be consistent with the dignity of the government to treat with this leader of pirates and smugglers.

The consultation resulted in a decision not to have anything to do with Lafitte in the way of negotiations, and to hurry forward the preparations which had been made for the destruction of the dangerous and injurious settlement at Barrataria.  In consequence of this action of the council, Commodore Patterson sailed in a very few days down the Mississippi and attacked the pirate settlement at Barrataria with such effect that most of her ships were taken, many prisoners and much valuable merchandise captured, and the whole place utterly destroyed.  Lafitte, with the greater part of his men, had fled to the woods, and so escaped capture.

Captain Lockyer at the appointed time arrived off the harbor of Barrataria and blazed away with his signal guns for forty-eight hours, but receiving no answer, and fearing to send a boat into the harbor, suspecting treachery on the part of Lafitte, he was obliged to depart in ignorance of what had happened.

When the papers and letters which had been sent to Governor Claiborne by Lafitte were made public, the people of Louisiana and the rest of the country did not at all agree with the Governor and his council in regard to their decision and their subsequent action, and Edward Livingston, a distinguished lawyer of New York, took the part of Lafitte and argued very strongly in favor of his loyalty and honesty in the affair.
