Background and detail

Background. The Strait of Magellan is a navigable sea route in southern Chile, separating mainland South America from Tierra del Fuego. Considered a vital passage between the Atlantic and Pacific oceans, the strait was a strategic prize. By the 19th century, Chilean authorities were concerned about potential foreign settlements, particularly by Great Britain or France, prompting the government to secure the region.

Expedition. President Manuel Bulnes ordered a naval expedition to claim the strait after consulting Bernardo O'Higgins. The mission was entrusted to John Williams Wilson, a British-born Chilean Navy officer. He commanded the schooner Ancud, a fifty-ton vessel built specifically for the purpose in San Carlos de Ancud. The ship departed from Ancud on May 22, 1843, carrying the crew tasked with establishing a Chilean presence in the region.
