August 1, 1801 – The American schooner USS Enterprise captures the Tripolitan polacca, Tripoli
The Action of 1 August 1801 was a single-ship action of the First Barbary War fought between the American schooner USS Enterprise and the Tripolitan polacca Tripoli off the coast of modern-day Libya.
As part of Commodore Richard Dale's Mediterranean Squadron, Enterprise had been deployed with the American force blockading the Vilayet of Tripoli. Enterprise, under the command of Lieutenant Andrew Sterett, had been sent by Commodore Dale to gather supplies at Malta. While cruising towards Malta, Enterprise engaged the Tripoli, commanded by Admiral Rais Mahomet Rous. Tripoli put up a stubborn fight, and the engagement lasted for three hours before the polacca was finally captured by the Americans.
Although the Americans had taken the vessel, Sterett had no orders to take prizes and so was obliged to release her. Enterprise completed her journey to Malta, and received honor and praise from the squadron's Commodore on her return to the fleet. The success of the battle boosted morale in the United States, since it was that country's first victory in the war against the Tripolitans. The opposite occurred in Tripoli, where morale sank heavily upon learning of Tripoli's defeat. Despite Enterprise's triumph, the war continued indecisively for another four years.
