The Wager Mutiny was the mutiny of the crew of HMS Wager after she was wrecked on a desolate island off the west coast of Chile in 1741. The ship was part of a squadron commanded by George Anson and bound to attack Spanish interests in the Pacific. Wager lost contact with the squadron whilst rounding Cape Horn, ran aground and wrecked on the west coast of Chile in May 1741. The main body of the crew mutinied against the captain, David Cheap, abandoned him and his loyal crew members, and returned in a modified open boat to England via the Strait of Magellan.
