Crossing of the Andes: Many soldiers of Juan Gregorio de las Heras are captured during the action of Picheuta.

The Crossing of the Andes was one of the most important feats in the Argentine and Chilean wars of independence. A combined army of Argentine soldiers and Chilean exiles crossed the Andes mountains, which separate Argentina from Chile, to invade Chile, leading to its liberation from Spanish rule.

In the Spanish American Wars of Independence, the action of Picheuta was a military engagement that took place on January 24, 1817, during the Crossing of the Andes.
