1826-1830 - FOUR BRITISH HYDROGRAPHIC CAMPAIGNS TO THE PATAGONIA AND TIERRA DEL FUEGO

During the course of 1825 Lords of the British Admiralty considered strategic and economic desirability of implementing an ambitious hydrographic survey in the southern coast of South America that is, itself the eastern and western coasts of Patagonia and Tierra del Fuego

Between 1826 and 1830, Commander and Hydrographer Australian Phillip Parker King, of the British Royal Navy, led the first stage of an unprecedented undertaking hydrographic survey developed in Magellanic waters, whose relevance would be central to the history of geographical knowledge and progress navigation. The work carried out  by the squadron ships composed by HMS "Adventure", HMS "Beagle" and HMS "Adelaide" throughout four extensive campaigns under the direct supervision and responsibility of King.

His contribution in this regard would become at least similar in importance to the discoverers and exploratory unprecedented feats of Ferdinand Magellan and Juan Ladrillero. It is also testimony to the company headed by King, the many names it up today due to the Magellanic nautical geography, to which must be added their contributions to natural science and ethnography.

The results of the expedition of Phillip Parker King were published in the first volume of the work entitled "Narrative of the Surveying Voyages of His Majesty's Ships 'Adventure' and 'Beagle' between the years 1826 and 1836", published in 1839 by Captain Robert Fitz Roy, who directed the second expedition, between 1832 and 1836, whose relationship, in turn, is included in the second volume of the work referred to, which features a classic of Southern literature.

In 1855, Captain King was promoted to rear admiral, the first born in Australia to achieve this degree in the Royal Navy.
