January 20, 1839
In the context of the War against the Peru-Bolivian Confederation (1836-1839), the general Manuel Bulnes, Commander in Chief of the Restorative Army, decisively defeats the confederate army of Marshal Andrés de Santa Cruz in this battle. This battle gave rise to the famous “March of Yungay,” which for many years was one of the main anthems of our homeland during various military celebrations. Additionally, this conflict played a key role in the notion of Chilean identity and in reinforcing a national identity and cohesion in formation.
Such was the valor demonstrated by the Chilean soldiers—mostly mestizos—that this battle is recognized as one of the most exemplary in our military history, in whose honor January 20 of each year is commemorated as “Chilean Roto Day.”

In the triumph of Yungay, a Chilean woman also achieved glory, the cantinera Candelaria Pérez, who accompanied the soldiers of Carampangue. She is the first woman for whom there are records of her participation in the Army and in a military conflict. Her role as a cantinera and her attainment of the rank of second lieutenant for her services mark the beginning of the official presence of women in the Army.

A historical work that recounts and commemorates the Battle of Yungay from a perspective that links this event to the construction of a Chilean identity, especially through the figure of the roto chileno as a popular emblem.
