Cause

During the First Barbary War, the United States deployed a naval squadron to blockade Tripoli and suppress Tripolitan piracy against American merchant shipping. Two American warships, USS John Adams and USS Enterprise, encountered a Tripolitan polacre escorted by nine gunboats while enforcing that blockade.

Event

On 22 June 1803, the American vessels engaged the Tripolitan force in a sharp forty-five-minute action. The gunboats withdrew, and the polacre was abandoned by its crew. When the Tripolitans attempted to retake the vessel, the Americans re-engaged, ultimately destroying the polacre in a large explosion.

Consequence

The decisive American victory ironically prompted Commodore Richard Valentine Morris to conclude the blockade was unnecessary. Four days later he lifted the blockade and sailed for Malta, allowing the Tripolitans to regroup and resume attacks on U.S. merchant vessels. President Thomas Jefferson was angered by this decision and relieved Morris of his command.
