Peruvian War of Independence
The "United States Naval Forces on Pacific Station" was established in 1818, with the USS "Macedonian" under John Downes setting sail to protect American interests in the Pacific Ocean. The "Macedonian" served in Chile until March 1821, when it was relieved by the USS "Constellation" under Charles G. Ridgely. These two single-frigate instances of the Pacific Station supported the Liberating Expedition of Peru in the Peruvian War of Independence.
