Considerations of this nature made a deep impression upon Barron, and induced him to view the cause in which Eaton had embarked, in a most unfavorable light; honor and policy, however, forbade the immediate abandonment of Hamet. The Argus and Hornet were therefore laden with ammunition and stores for the supply of the expedition, and despatched to Bomba, where their opportune arrival and the assistance rendered by them at Derne have been already noticed. A letter was also carried by the Argus from Barron to Eaton, in which after applauding his courage and perseverance, he represents to him "that their Government in consenting to act in concert with Hamet, did not contemplate the measure as leading necessarily and absolutely to his establishment in Tripoli, but as a means which, provided there existed energy in the exiled Prince, and attachment to his person on the parts of his former subjects, might be employed to the common furtherance and advantage of his claims and the American cause; that if he possessed these qualities, and had sufficient interest with the people, he might after getting possession of Derne and Bengazi, move on with firm steps, and conduct his followers to the gates of the capital, in aid of which, operations would be prosecuted with vigor by the squadron, as soon as the season would permit." He declared, however, that "he must withhold his sanction from any convention or engagement, tending to impress upon Hamet, the idea that the Americans had bound themselves to place him on the throne," such engagements being unauthorized and inexpedient, particularly taking into view, the situation in which Bainbridge and their other captive countrymen might be placed by this co-operation: that he should not suffer any convention with the Prince, to interfere with that "perfect and uncontrolled power of choice and action, in concluding a pacification with the Pasha, which it was important under such circumstances to preserve;" and "that honorable and advantageous terms being once offered, and accepted by the representative of government appointed to treat for peace, all support to Hamet must necessarily cease." The request for a detachment of marines could not be complied with, "as the services of all would be required on board their respective ships." The confused and indeed contradictory injunctions contained in this letter, mark the utmost indecision in the mind of the writer, and were calculated only to puzzle the person to whom they were directed. He is discouraged from prosecuting the enterprise in which he had engaged, while he is at the same time assured, that the utmost assistance will be afforded to its advancement by the squadron. A few days after the sailing of the Argus and Hornet, the Nautilus was also sent to Derne, with additional supplies and some cannon, which proved serviceable in the attacks on that place.
