The Battle of Maipú (Spanish: Batalla de Maipú) was fought near Santiago, Chile on 5 April 1818, between South American rebels and Spanish royalists, during the Chilean War of Independence. The Patriot rebels led by Argentine general José de San Martín effectively destroyed the Spanish forces commanded by General Mariano Osorio, and completed the independence of the core area of Chile from Spanish domination.
