It was after the fifth ineffectual assault that Preble determined on a desperate stroke. He resolved to fit out a fireship and to send her into the very jaws of death, hoping to destroy the Tripolitan gunboats and at the same time to damage the castle and the town. He chose for this perilous enterprise the old Intrepid which had served her captors so well, and out of many volunteers he gave the command to Captain Richard Somers and Lieutenant Henry Wadsworth. The little ketch was loaded with a hundred barrels of gunpowder and a large quantity of combustibles and made ready for a quick run by the batteries into the harbor. Certain death it seemed to sail this engine of destruction past the outlying reefs into the midst of the Tripolitan gunboats; but every precaution was taken to provide for the escape of the crew. Two rowboats were taken along and in these frail craft, they believed, they could embark, when once the torch had been applied, and in the ensuing confusion return to the squadron.
Somers selected his crew of ten men with care, and at the last moment consented to let Lieutenant Joseph Israel join the perilous expedition. On the night of the 4th of September, the Intrepid sailed off in the darkness toward the mouth of the harbor. Anxious eyes followed the little vessel, trying to pierce the blackness that soon enveloped her. As she neared the harbor the shore batteries opened fire; and suddenly a blinding flash and a terrific explosion told the fate which overtook her. Fragments of wreckage rose high in the air, the fearful concussion was felt by every boat in the squadron, and then darkness and awful silence enfolded the dead and the dying. Two days later the bodies of the heroic thirteen, mangled beyond recognition, were cast up by the sea. Even Captain Bainbridge, gazing sorrowfully upon his dead comrades could not recognize their features. Just what caused the explosion will never be known. Preble always believed that Tripolitans had attempted to board the Intrepid and that Somers had deliberately fired the powder magazine rather than surrender. Be that as it may, no one doubts that the crew were prepared to follow their commander to self-destruction if necessary. In deep gloom, the squadron returned to Syracuse, leaving a few vessels to maintain a fitful blockade off the hated and menacing coast.
Far away from the sound of Commodore Preble's guns a strange, almost farcical, intervention in the Tripolitan War was preparing. The scene shifts to the desert on the east, where William Eaton, consul at Tunis, becomes the center of interest. Since the very beginning of the war, this energetic and enterprising Connecticut Yankee had taken a lively interest in the fortunes of Hamet Karamanli, the legitimate heir to the throne, who had been driven into exile by Yusuf the pretender. Eaton loved intrigue as Preble gloried in war. Why not assist Hamet to recover his throne? Why not, in frontier parlance, start a back-fire that would make Tripoli too hot for Yusuf? He laid his plans before his superiors at Washington, who, while not altogether convinced of his competence to play the king-maker, were persuaded to make him navy agent, subject to the orders of the commander of the American squadron in the Mediterranean. Commodore Samuel Barron, who succeeded Preble, was instructed to avail himself of the cooperation of the ex-Pasha of Tripoli if he deemed it prudent. In the fall of 1804 Barron dispatched Eaton in the Argus, Captain Isaac Hull commander, to Alexandria to find Hamet and to assure him of the cooperation of the American squadron in the reconquest of his kingdom. Eaton entered thus upon the coveted role: twenty centuries looked down upon him as they had upon Napoleon.
A mere outline of what followed reads like the scenario of an opera bouffe. Eaton ransacked Alexandria in search, of Hamet the unfortunate but failed to find the truant. Then acting on a rumor that Hamet had departed up the Nile to join the Mamelukes, who were enjoying one of their seasonal rebellions against constituted authority, Eaton plunged into the desert and finally brought back the astonished and somewhat reluctant heir to the throne. With prodigious energy Eaton then organized an expedition which was to march overland toward Derne, meet the squadron at the Bay of Bomba, and descend vi et armis upon the unsuspecting pretender at Tripoli. He even made a covenant with Hamet promising with altogether unwarranted explicitness that the United States would use "their utmost exertions" to reestablish him in his sovereignty. Eaton was to be "general and commander-in-chief of the land forces." This aggressive Yankee alarmed Hamet, who clearly did not want his sovereignty badly enough to fight for it.
The international army which the American generalissimo mustered was a motley array: twenty-five cannoneers of uncertain nationality, thirty-eight Greeks, Hamet and his ninety followers, and a party of Arabian horsemen and camel-drivers—all told about four hundred men. The story of their march across the desert is a modern Anabasis. When the Arabs were not quarreling among themselves and plundering the rest of the caravan, they were demanding more pay. Rebuffed they would disappear with their camels into the fastnesses of the desert, only to reappear unexpectedly with new importunities. Between Hamet, who was in constant terror of his life and quite ready to abandon the expedition, and these mutinous Arabs, Eaton was in a position to appreciate the vicissitudes of Xenophon and his Ten Thousand. No ordinary person, indeed, could have surmounted all obstacles and brought his balky forces within sight of Derne.
Supported by the American fleet which had rendezvoused as agreed in the Bay of Bomba, the four hundred advanced upon the city. Again the Arab contingent would have made off into the desert but for the promise of more money. Hamet was torn by conflicting emotions, in which a desire to retreat was uppermost. Eaton was, as ever, indefatigable and indomitable. When his forces were faltering at the crucial moment, he boldly ordered an assault and carried the defenses of the city. The guns of the ships in the harbor completed the discomfiture of the enemy, and the international army took possession of the citadel. Derne won, however, had to be resolutely defended. Twice within the next four weeks, Tripolitan forces were beaten back only with the greatest difficulty. The day after the second assault (June 10th) the frigate Constellation arrived off Derne with orders which rang down the curtain on this interlude in the Tripolitan War. Derne was to be evacuated! Peace had been concluded!
Just what considerations moved the Administration to conclude peace at a moment when the largest and most powerful American fleet ever placed under a single command was assembling in the Mediterranean and when the land expedition was approaching its objective, has never been adequately explained. Had the President's belligerent spirit oozed away as the punitive expeditions against Tripoli lost their merely defensive character and took on the proportions of offensive naval operations? Had the Administration become alarmed at the drain upon the treasury? Or did the President wish to have his hands free to deal with those depredations upon American commerce committed by British and French cruisers which were becoming far more frequent and serious than ever the attacks of the Corsairs of the Mediterranean had been? Certain it is that overtures of peace from the Pasha were welcomed by the very naval commanders who had been most eager to wrest a victory from the Corsairs. Perhaps they, too, were wearied by prolonged war with an elusive foe off a treacherous coast.
How little prepared the Administration was to sustain a prolonged expedition by land against Tripoli to put Hamet on his throne, appears in the instructions which Commodore Barron carried to the Mediterranean. If he could use Eaton and Hamet to make a diversion, well and good; but he was at the same time to assist Colonel Tobias Lear, American Consul-General at Algiers, in negotiating terms of peace, if the Pasha showed a conciliatory spirit. The Secretary of State calculated that the moment had arrived when peace could probably be secured "without any price and pecuniary compensation whatever."
Such expectations proved quite unwarranted. The Pasha was ready for peace, but he still had his price. Poor Bainbridge, writing from captivity, assured Barron that the Pasha would never let his prisoners go without a ransom. Nevertheless, Commodore Barron determined to meet the overtures which the Pasha had made through the Danish consul at Tripoli. On the 24th of May he put the frigate Essex at the disposal of Lear, who crossed to Tripoli and opened direct negotiations.
The treaty which Lear concluded on June 4, 1805, was an inglorious document. It purchased peace, it is true, and the release of some three hundred sad and woe-begone American sailors. But because the Pasha held three hundred prisoners, and the United States only a paltry hundred, the Pasha was to receive sixty thousand dollars. Derne was to be evacuated and no further aid was to be given to rebellious subjects. The United States was to endeavor to persuade Hamet to withdraw from the soil of Tripoli—no very difficult matter—while the Pasha on his part was to restore Hamet's family to him—at some future time. Nothing was said about tribute; but it was understood that according to ancient custom each newly appointed consul should carry to the Pasha a present not exceeding six thousand dollars.
