Mr. Eaton, however (our late consul), on his return from the Mediterranean, possessing personal knowledge of the scene and having confidence in the effect of a joint operation, we authorized Commodore Barron, then proceeding with his squadron, to enter into an understanding with Hamet if he should deem it useful; and as it was represented that he would need some aids of arms and ammunition, and even of money, he was authorized to furnish them to a moderate extent, according to the prospect of utility to be expected from it. In order to avail him of the advantages of Mr. Eaton's knowledge of circumstances, an occasional employment was provided for the latter as an agent for the Navy in that sea. Our expectation was that an intercourse should be kept up between the ex-Bashaw and the commodore; that while the former moved on by land our squadron should proceed with equal pace, so as to arrive at their destination together and to attack the common enemy by land and sea at the same time. The instructions of June 6 to Commodore Barron shew that a cooperation only was intended, and by no means an union of our object with the fortune of the ex-Bashaw, and the commodore's letters of March 22 and May 19 prove that he had the most correct idea of our intentions. His verbal instructions, indeed, to Mr. Eaton and Captain Hull, if the expressions are accurately committed to writing by those gentlemen, do not limit the extent of his cooperation as rigorously as he probably intended; but it is certain from the ex-Bashaw's letter of January 3, written when he was proceeding to join Mr. Eaton, and in which he says, "Your operations should be carried on by sea, mine by land," that he left the position in which he was with a proper idea of the nature of the cooperation. If Mr. Eaton's subsequent convention should appear to bring forward other objects, his letter of April 29 and May 1 views this convention but as provisional, the second article, as he expressly states, guarding it against any ill effect; and his letter of June 30 confirms this construction.
