Jean-Francois de la Perouse (1741-1788) joined the French navy at the age of fifteen and fought against the British in the Seven Years War. After the war he led an expedition around the world to complete the Pacific discoveries of James Cook. Among his many surveys he charted most of the Strait of Tartary and the islanders he encountered told him that the island was called "Tchoka". The island is known as Sakhalin today.
Good clean example.
