Commodore George Anson had set out from Britain in 1740 as leader
of a squadron of eight ships, charged with attacking Spain's
colonial possessions in the Pacific as part of the War of Jenkins'
Ear. Only one vessel survives the voyage, but it ends up completing
a circumnavigation of the globe, returning to Britain on 15th June
1744.
