The Chilean ship San Martín was originally launched in 1802 as the Cumberland, a three-decker East Indiaman built for the British East India Company. Her construction featured multiple decks and a robust design typical of East Indiamen of that era, intended to carry both cargo and passengers on long voyages between India and England. She was actively engaged in seven voyages from 1802 to 1815, with her routes covering key ports such as Madras, Penang, Whampoa (Canton), and St Helena. Cumberland distinguished herself early in her service through her involvement in significant maritime events. Notably, during her second voyage in 1804, she participated in the Battle of Pulo Aura, where a fleet of East Indiamen under Commodore Nathaniel Dance successfully intimidated and drove off a superior French squadron commanded by Contre-Admiral Charles-Alexandre Durand Linois. Cumberland also engaged in minor combat and defensive actions, including an encounter with the French ship Marengo in 1805, where she exchanged fire during a convoy escort. Throughout her service, Cumberland was commanded by various captains, including William Ward Farrer, William Ward Tarres, Peter Wedderburn, and Thomas Hutton Wilkinson, each holding letters of marque that authorized offensive action against French vessels during the Napoleonic Wars. Her voyages were marked by extensive travel across the Indian Ocean and China Seas, showcasing her as a versatile and resilient vessel. In 1818, the Chilean government purchased her in London for 210,000 pesos, and she was renamed San Martín. Armed with 64 guns, she became a key member of the First Chilean Navy Squadron under Commander William Wilkinson. San Martín participated in critical battles, notably contributing to the defeat of a Spanish expeditionary force in 1818 and supporting the Liberation Expedition of Perú under Captain Lord Thomas Cochrane. Her service came to an end when she was wrecked off the coast of Peru in July 1821. Although her crew was saved, the vessel was lost while carrying valuable cargo, including the "Impost levied on the Extremedeos" and some silver. Her wreck marked the end of her notable maritime career, but her involvement in pivotal naval conflicts underscores her importance in both British and Chilean naval history.
