Assault on the 4th column Argentina at the Battle of Curupaity

Executed in a Naturalist style with Naïve undertones, the painting features muted greens and browns, enhancing its realistic tone. López employed chiaroscuro to create depth, evident in the interplay of light and shadow across the detailed, populated landscape.

Created by López in 1900, the painting is now part of the National Museum of Fine Arts collection in Buenos Aires, Argentina.

The Paraguayan War (1864-1870) was a significant South American conflict. López's participation in the war and his subsequent depiction of it reflect the era's emphasis on documenting historical events through art.

While specific lasting impacts of the painting on broader art movements are not prominently noted, it remains a valued historical record of the Paraguayan War, combining López's military experience with his artistic practice.
