The British Fleet Sailing into Lisbon Harbour, 1736
Portugal had appealed to Britain for military assistance against mounting Spanish aggression, but Britain was determined not to become embroiled in another war. Instead, a fleet of thirty ships under Admiral Sir John Norris was sent to Lisbon
in 1736 to protect British maritime trade, as well as British interests in Portuguese Brazil trade. The majority of the ships remained on uneventful guard duty near Lisbon for almost two years.
