In short: The HMS Wager was meant to support a Pacific expedition, but after striking rocks off the coast of Chile, the vessel became a site of mutiny and murder. With official authority gone, the survivors split into factions, leading to a harrowing five-year struggle to return home to England.

Originally built as an East Indiaman in about 1734, the HMS Wager was purchased by the Royal Navy in 1739. Converted into a 28-gun sixth-rate ship, it joined Commodore George Anson's squadron to attack Spanish interests in the Pacific. By the time it sailed in August 1740, the ship was manned by 120 men, many of whom were aged or disabled seamen recruited as a cost-saving measure. The vessel never reached its destination; after losing contact with the squadron in severe weather near Cape Horn, it struck rocks on 14 May 1741, grounding on what is now known as Wager Island.

The disaster triggered a total collapse of order. In the Royal Navy of 1741, an officer's commission was tied to their specific ship; once the Wager was lost, official authority effectively vanished, and the crew stopped receiving pay. This legal vacuum, coupled with brutal conditions and infighting, split the survivors. A group of 81 men led by gunner John Bulkeley attempted to sail home via the east coast of South America, while a smaller party of 20, including Captain David Cheap and Midshipman John Byron, remained on the island. Only a fraction of these men eventually returned to England over five years later.

The wreck site itself has been transformed by time and geology. Wager Island lies near an active tectonic plate boundary and has been pushed upwards by about 7 meters due to 94 earthquakes since 1741. A 2006 expedition identified a piece of the wooden hull, which showed signs of burning—likely from 18th-century Spanish salvors seeking to recover metal. The expedition also confirmed that the survivors' camp, once located near an inlet, is now situated by an inland lake, illustrating how seismic activity has physically reshaped the landscape of this infamous maritime tragedy.
