In what year did Marines storm the Barbary pirates' stronghold in Tripoli?

The year 1805 is significant in U.S. military history for the attack on the Barbary pirates' stronghold in Tripoli, which was part of the First Barbary War. This conflict arose from issues related to piracy against American merchant vessels in the Mediterranean. The Marines, alongside U.S. Navy forces, conducted a daring assault to capture the fortress of Derna in Libya, which marked the first time the United States deployed its military to achieve foreign policy objectives beyond its borders.

The successful siege demonstrated the effectiveness of the Marine Corps, solidifying their reputation for undertaking rapid, decisive action in hostile environments. The event is famously memorialized in the Marine Corps hymn and is often cited as a pivotal moment in U.S. military history, symbolizing the resolve of the young nation to protect its interests and uphold international trade against piracy.
