This map depicts a harbor on the Chilean coast identified during Commodore George Anson's circumnavigation. Published as part of the documentation of Anson's voyage, this map is a product of the mid-18th century's heightened interest in maritime exploration and naval expeditions.
The map offers a detailed depiction of the harbor and surrounding coastline, including soundings, anchorage points, and coastal features such as promontories, islets, and wooded areas. Notably, it includes a scale of miles, a compass rose, and a detailed illustration of an offshore island labeled as "This Island is called Inchin by the Indians." These features suggest the cartographer's focus on navigational utility and accurate representation, critical for naval and merchant vessels operating in these waters.
The map illustrates the account of Commodore Anson's voyage, a key British naval expedition during the War of Jenkins' Ear (1739–1748). Anson's squadron was tasked with disrupting Spanish trade in the Pacific and returning with captured treasure. After rounding Cape Horn under grueling conditions, the squadron endured severe losses due to storms, scurvy, and desertion. This harbor, discovered by a victualler (a supply ship) accompanying Anson's fleet, provided a vital refuge for the beleaguered ships. The identification of safe harbors along the Chilean coast was crucial for replenishing supplies and repairing vessels during the long and arduous voyage.
