Which historic event is recognized in the Marine Corps motto?

The Marine Corps motto, "Semper Fidelis," which translates to "Always Faithful," is deeply linked to the historical event of the landing at Tripoli, part of the First Barbary War in the early 1800s. During this conflict, Marines made a notable landing at Derna, Tripoli, which was a significant action against piracy and a demonstration of American resolve. This event is often celebrated as a pivotal moment in Marine Corps history, symbolizing their commitment and loyalty.

The phrase "to the shores of Tripoli" is incorporated in the official hymn of the Marines, acknowledging their role in this military action and reinforcing the motto's essence of fidelity to duty and country. This connection emphasizes the Marine Corps' enduring legacy and the continued importance of their traditions. The other historical events listed carry significance in American history but do not have the same direct relationship with the Marine Corps motto as the landing at Tripoli does.
