Andres Avelino Caceres was an Ayacucho-born career officer who fought in earlier Peruvian conflicts before playing a leading role in resisting the Chilean invasion during the War of the Pacific, surviving the Battle of Tarapaca (1879) despite severe wounds and helping organise the defence of Lima, which fell to Chilean forces in January 1881. Rather than accept defeat, Caceres withdrew into the central Peruvian highlands (the Sierra), where he organised and led a prolonged guerrilla resistance campaign known as the Campana de la Brena, mobilising indigenous highland communities and using the terrain to harass Chilean occupation forces for nearly three years, most notably at the Battle of Huamachuco (10 July 1883), a costly defeat that nonetheless marked the campaign's final major action before Peru's negotiators concluded the Treaty of Ancon. Celebrated after the war as the "Wizard of the Andes" for his guerrilla tactics, Caceres parlayed his military prestige into the presidency of Peru, serving from 1886 to 1890 and again briefly in 1894-1895 before being overthrown, and he remains one of Peru's most honoured national military figures for his refusal to accept the Chilean occupation.
