At the beginning of the war with Spain and France in 1740, George Anson was given charge of a squadron of six ships with the rank of commodore and ordered to the Pacific to attack Spanish possessions and to capture one of the Acapulco treasure ships. Anson's second lieutenant on the 'Centurion' during the voyage round the world, 1740-44, was Piercy Brett whose drawings were engraved for the official account of the voyage. They demonstrate the concerns of naval officers in making such drawings, in particular the precise delineation of landfall which Brett here annotates with a key. The lower drawing, with the title, 'The Papps bearing No(rth) dist(ance) 7 Leagues', was engraved for the published account as plate XXX (p277).
