Francis Drake's circumnavigation began on the 15th of November 1577 when the fleet set out from Plymouth. The voyage concluded with the arrival at the English Channel on the 26th of September 1580.

Thomas Doughty was executed for treachery and incitement to mutiny after accusing Drake of witchcraft following a severe storm. Evidence included testimony from carpenter Edward Bright and Doughty's admission of revealing the true intent of the voyage to Lord Burghley.
Francis Drake claimed sovereignty over Northern California where he landed on the 17th of June 1579 near what is now Depoe Bay. He named this territory Nova Albion or New Britain in the name of Queen Elizabeth I.
