The Battle of Cliza was fought between the Royalist Upper Peru Army and Galeano Moretti's Argentine patriot company on 3 November 1814 during the Bolivian War of Independence.
Based from Paraguay and Salta, the Argentine patriot Galeano Moretti assembled a sizeable company of Argentine, Bolivian, Paraguayan, and Uruguayan guerrillas for raids into Royalist-controlled Upper Peru from August 1814. In November 1814, Moretti crossed the Paraguayan frontier into Upper Peru (present-day Bolivia) to search for defenseless villages to plunder or small Royalist armies to destroy. While Moretti's party sacked the village of Cliza, however, the Spanish general Pio de Tristan led a massive army to ambush the Patriots. In the ensuing battle, the Patriots scrambled to resist the Royalist attack. Moretti was injured while charging into the Royalist ranks on horseback, and his men carried him away. He was able to slip away with 21 of his men, and he recruited dozens of Bolivian volunteers from nearby villages and determined to stay in Upper Peru, feeding his army with stolen supplies and rallying Bolivian patriots to his cause.
