Cook departed from Plymouth on August 26, 1768 on officially a scientific journey that carried him across the Atlantic and around the difficult-to-traverse Cape Horn in South America toward the south Pacific. He carried with him sealed secret instructions from the Admiralty, which he’d been ordered not to open until after completing the astronomical work.
Cook left no record of when he opened the sealed packet of secret orders he’d been given by the Admiralty, but on August 9, 1769, as he left Bora-Bora and the other Society Isles behind, he made sail southward.
For centuries, the myth of Cook’s voyage as an essentially scientific undertaking persisted, although plenty of people had already surmised the government's hand in Cook's journeys. Still, a full copy of the Admiralty’s “Secret Instructions” weren't made public until 1928.
