Commodore Edward Preble assembled his considerable American fleet just outside Tripoli harbor in August 1804, determined to punish the city and its corsairs, and force Yusuf Karamanli, the Dey of Tripoli, to sue for peace.

William Eaton led the first successful invasion of a foreign land by the United States when in 1804 he led a handful of Marines and a hodgepodge assembly of Christian mercenaries and unruly Arabs to conquer the Tripolitan port city of Derne.

Captain William Bainbridge managed to run the USS Philadelphia hard aground on a submerged reef in Tripoli harbor on October 31, 1803, and this pristine frigate, one of the top ships in the United States Navy was now in grave danger of falling into the hands of the Tripolitan pirates.

Soon after Thomas Jefferson was sworn in as our country’s third president on March 4, 1801, Yusuf Karamanli, the Pasha of Tripoli, decided to renounce the existing treaty his North African province had with the United States.
