This episode picks up after the War of 1812, when American merchantmen returned to open waters and resumed global trade. As routes expanded into the Pacific, Southeast Asia became a key target for American commerce.

That success brought new risks. In 1831, the merchant ship Friendship was attacked and looted by pirates at Quallah Battoo. President Andrew Jackson authorized a punitive expedition led by Commodore John Downes and a large detachment of Marines. What followed was a brutal amphibious assault designed to send a message: the United States would protect its merchants abroad by force, if necessary. 

Archibald Henderson shaped the Marine Corps during one of its most transformative periods. From the decks of the USS Constitution during the War of 1812 to street battles in Washington, D.C., he led from the front and elevated the Corps’ reputation through four decades of continuous service. Under his leadership, Marines adapted to shifting warfare to fighting pirates, engaging Native American tribes, and storming Chapultepec during the Mexican-American War. 

He guided the Corps through political instability, structural reform, and global deployments, turning a small force into a professional, reliable military arm. He led Marines in battle well into his seventies, resisted political interference, and left behind a legacy still felt today. This episode covers the second half of his career, the events that defined his leadership, and how he positioned the Marine Corps for what came next. Henderson built the Corps to last.
