The Second Battle of Huachi was a confrontation that occurred on 12 September 1821 between pro-independence troops led by General Antonio José de Sucre and Royalist troops led by General Melchor Aymerich, president of the Real Audiencia of Quito. Sucre, after having won the Battle of Yaguachi on 19 August, advanced towards Quito. The Spanish, who followed closely, positioned themselves to do battle in a field called Huachi, where they had already defeated Guayaquil forces a year before.
