In the event it was found that after placing the ex-Bashaw in possession of Derne, one of the most important cities and provinces of the country, where he had resided himself as governor, lie was totally unable to command any resources or to bear any part in cooperation with us. This hope was then at an end, and we certainly had never contemplated, nor were we prepared, to land an army of our own, or to raise, pay, or subsist an army of Arabs to march from Derne to Tripoli and to carry on a land war at such a distance from our resources. Our means and our authority were merely naval, and that such were the expectations of Hamet his letter of June 29 is an unequivocal acknowledgment. While, therefore, an impression from the capture of Derne might still operate at Tripoli, and an attack on that place from our squadron was daily expected. Colonel Lear thought it the best moment to listen to overtures of peace then made by the Bashaw. He did so, and while urging provisions for the United States he paid attention also to the interests of Hamet, but was able to effect nothing more than to engage the restitution of his family, and even the persevering in this demand suspended for some time the conclusion of the treaty. In operations at such a distance it becomes necessary to leave much to the discretion of the agents employed, but events may still turn up beyond the limits of that discretion. Unable in such a case to consult his Government, a zealous citizen will act as he believes that would direct him were it apprised of the circumstances, and will take on himself the responsibility. In all these cases the purity and patriotism of the motives should shield the agent from blame, and even secure a sanction where the error is not too injurious. Should it be thought by any that the verbal instructions said to have been given by Commodore Barron to Mr. Eaton amount to a stipulation that the United States should place Hamet Caramalli on the throne of Tripoli--a stipulation so entirely unauthorized, so far beyond our views, and so onerous could not be sanctioned by our Government--or should Hamet Caramalli, contrary to the evidence of his letters of January 3 and June 29, be thought to have left the position which he now seems to regret, under a mistaken expectation that we were at all events to place him on his throne, on an appeal to the liberality of the nation something equivalent to the replacing him in his former situation might be worthy its consideration.
