Eaton had spent a year at home, urging upon the authorities, whenever the settlement of his accounts took him to Washington, more effective measures against Tripoli,--and particularly an alliance with Hamet Caramanli, the Ex-Pacha, who had been driven from his throne by his brother Jusuf, a much more able man. In spite of his bitter flings at their do-nothing policy, the Administration sent him out in the fleet, commissioned as General Agent for the Barbary Regencies, with the understanding that he was to join Hamet and assist him in an attack upon Derne. His instructions were vague and verbal; he had not even a letter to our proposed ally. Eaton was aware of his precarious position; but the hazardous adventure suited his enterprising spirit, and he determined to proceed in it. "If successful, for the public,--if unsuccessful, for myself," he wrote to a friend, quoting from his classical reminiscences; "but any personal risk," he added, with a rhetorical flourish, "is better than the humiliation of treating with a wretched pirate for the ransom of men who are the rightful heirs of freedom." He sailed in the John Adams, in June, 1804. The President, Congress, Essex, and Constellation were in company. On the 5th of September the fleet anchored at Malta. In a few weeks the plan of the expedition was settled, and the necessary arrangements made, with the consent and under the supervision of Barron. Eaton then went on board the United States brig Argus, Captain Isaac Hull, detached specially on this service by the Commodore, and sailed for Alexandria, to hunt up Hamet and to replace him upon a throne. On the 8th of December, Eaton and his little party, Lieutenant Blake, Midshipmen Mann and Danielson, of the navy, and Lieutenant O'Bannon of the marines, arrived in Cairo. Here they learned that Hamet had taken service with the rebel Mamlouk Beys and was in command of an Arab force in Upper Egypt. A letter from Preble to Sir Alexander Ball insured the Americans the hearty good wishes of the English. They were lodged in the English house, and passed for United States naval officers on a pleasure-trip. In this character they were presented to the Viceroy by Dr. Mendrici, his physician, who had known Eaton intimately in Tunis, and was much interested in this enterprise. The recommendation of the Doctor obtained a private audience for Eaton. He laid his plans frankly before his Highness, who listened favorably, assured him of his approval, and ordered couriers to be sent to Hamet, bearing a letter of amnesty and permission to depart from Egypt.
