The Constellation arrived off Derne on the 11th of June, and it being at once supposed that she brought supplies and troops in aid of Hamet, the hopes of his partizans were excited to the highest pitch, while the Tripolines were so much dismayed, that they broke up their camp in haste, and retreated to the distance of fifteen miles from the town. When Eaton had examined the despatches brought by her, he saw at once that it would be a nice and difficult task to embark the Christians with Hamet and his followers in safety, as the inhabitants would place but little confidence in the Pasha's amnesty, and might be disposed to sacrifice their lives in revenge for this apparent desertion. He therefore took measures to conceal the real state of affairs; he ordered the troops to be inspected, distributed ammunition and rations, and sent off spies as if in anticipation of an attack. At night, patroles were placed to cut off all communication between the battery near the sea, which was occupied by the Christians and the town; the Constellation's boats came to the wharf, and the Christians, to their great astonishment, were all embarked and rowed off to the frigate, except the Americans. A message was then sent to Hamet, requesting an interview; he understood what was meant and instantly came with his retinue; they entered the boats, which had by that time returned, the Americans followed, and last of all went Eaton, just in time to escape the soldiery and inhabitants, who learning what was going on, rushed in distraction to the beach. Finding themselves deserted by those who had led them to take up arms against their tyrannical master, their rage burst forth in execrations against Hamet and his infidel friends. In the morning, the Tripoline agent landed and proclaimed amnesty to those who would return to their allegiance; but the place was already nearly deserted; the Arabs had plundered it of all that could be carried away and retreated to the mountains, accompanied by many of the inhabitants; those who remained rejected the terms of pardon offered them, and prepared to defend themselves to the last from the tops of their houses. What was their fate we have been unable to learn. At noon, on the 13th of June, Eaton writes, "In a few minutes, we shall lose sight of this deserted city, which has experienced as strange a reverse in as short a time, as ever recorded in the disasters of war." The Constellation arrived in a few days at Syracuse, where the men who had served with Eaton at Derne were paid off. The whole expenses of the expedition amounted to about forty thousand dollars.
