Crossing of the Andes

The Crossing of the Andes was one of the most important feats in the Argentine and Chilean wars of independence, in which an Argentine army liberated Chile from Spanish rule, in order to protect their country from possible Spanish incursions. Starting on 19 January 1817, an army of 5,423 soldiers, led by General José de San Martín, crossed the Andes from their camp, El Plumerillo, in the north of today's Mendoza Province, through more than 500 km of mountain ranges up to 4,000 m above mean sea level, in which the temperature could go from 30 °C during the day to −10° C during the night. The crossing took 21 days.
