While Great Britain was fighting the War of Jenkins' Ear with Spain in 1740, Commodore George Anson led a squadron of eight ships on a mission to disrupt or capture the Pacific Ocean possessions of the Spanish Empire. Returning to Britain in 1744 by way of China and thus completing a circumnavigation of the globe, the voyage was notable for the capture of the Manila galleon, but also for horrific losses from disease with only 188 men of the original 1,854 surviving. An account of the voyage was published in 1748 which being widely read by the general public was a great commercial success and "is still esteemed as the story of a remarkable voyage extremely well told."

The War of Jenkins' Ear was a conflict lasting from 1739 to 1748 between Britain and Spain. The majority of the fighting took place in New Granada and the Caribbean Sea, with major operations largely ended by 1742. It was related to the 1740 to 1748 War of the Austrian Succession. The name was coined in 1858 by British historian Thomas Carlyle, and refers to Robert Jenkins, captain of the British brig Rebecca, whose ear was allegedly severed by Spanish coast guards while searching his ship for contraband in April 1731.
