Watercolour sketch of the fort and settlement at George Town on Ascension Island, established after the British claimed the island in 1815. One of 14 scenes by Lieutenant E N Kendall portraying the coasts and islands of the South Atlantic, made during the voyage of HMS 'Chanticleer' under Captain Henry Foster (1828-1831). The purpose of the voyage was to ascertain the formation and outline of coasts and the direction of the principal ocean currents in both hemispheres. Foster took gravity observations and measurements, particularly by means of a Kater invariable pendulum. His research was published in 'Relation of a Journey through the South Atlantic, made upon the Royal Corvette 'Chanticleer' during the Years 1828-31' (London, 1834).
