In 1823–1824, Charles travelled around South America. This was at a time when there were active revolutionary movement, struggling for
independence from Spain. Charles had, in August 1820, already experienced some dangerous shore-life, when he and a fellow-officer were attacked by Spanish-Indian
gauchos near
Buenos Aires. His fellow-officer, Henry Finch, was killed, and Charles badly wounded. His trigger for exploring South America was largely due to his interest in developing pearl fisheries, having seen these in
Colombia in 1819. He was determined to invest in such fisheries and improve their operations, and, at the same time, seek out other opportunities for commercial enterprise. During the course of his travels, which lasted from March 1823 to April 1824, he visited
Colombia and
Venezuela, took a boat-trip up the
Cienega River, observed wildlife, native peoples, mineral mines and pearl-fisheries. He eventually managed to secure 'exclusive rights in Colombia for fishing for the pearl oysters with machinery,' for the London company of Rundell, Bridge and Rundell. After returning to London in April 1824, he wrote and published in 1825 his two-volume journal of his travels:
Journal of a Residence and Travels in Colombia, during the years 1823 and 1824, by Captain Charles Stuart Cochrane of the Royal Navy. It was dedicated to 'Simon Bolivar, Liberator and President of Colombia, Dictator of Peru, Generalissimo of the Armies &c &c &c'. He mentions in the Journal that had hoped to meet
Simón Bolívar, but that he had failed to do so. In the preface to this Journal, he explained that he wished to see 'a nation successful in the vindication of its rights, and triumphant over the mean and mistaken policy that would have condemned it to a perpetuity of sloth, ignorance, bigoted superstition, and slavery.' The Journal not only describes Charles's journeys, but also gives a history of the nationalist uprisings against Spain, and some notes on the commerce and industry of the region. Just a few years earlier, in January 1818, Charles's cousin
Thomas Cochrane, in disgrace and effectively sacked from the Royal Navy, had taken up the post of commander-in-chief of the
Chilean navy, where he conducted successful battles against the Spanish navy. In 1823, Thomas was appointed to command the navy of
Brazil, again with a view to liberating all of Brazil from Spanish rule. Charles's travels through the region were probably smoothed by his family connection. It is likely that Charles had persuaded his cousin
John Dundas Cochrane of the attractions of South America. John made two visits to Colombia – firstly in June 1824, and then, after returning briefly to London, in the following summer; in August 1825, he died of fever at
Valencia in Colombia shortly after his arrival. == Travels in Britain ==
