Tuyutí, campo de la batalla del 24 de mayo de 1866

What it is

Tuyutí is a patch of firm ground surrounded by marshes in the far south of Ñeembucú, a few kilometres from Paso de Patria. In May 1866 the bulk of the allied army that had crossed the Paraná weeks earlier camped here, and on the 24th of that month the first Battle of Tuyutí took place on this very ground. Historians regard it as the largest and bloodiest armed clash ever fought in South America. Today visitors find an open field, looked after by the community and local authorities, with a monument marking the battle. There are no big structures; what stays with you is the landscape of tall grass and wetlands, which explains why the terrain was so difficult for both armies. You get there by the road linking Pilar and Humaitá and finish the last stretch on local dirt roads. Tuyutí fits naturally into a Great War circuit in Ñeembucú: together with Paso de Patria, Estero Bellaco, Curupayty and Humaitá it lets you follow, in just a few kilometres, the allied advance towards the fortress.

Did you know…?

The name is rendered locally as "white mud"; the area was a dry islet in the middle of swamps, which is why the allies picked it as a camp.

The battle left its mark on place names: the neighbouring district of Mayor Martínez is named after a local-born officer who died of a cannon wound at Tuyutí.

History

After the clashes at Paso de Patria and Estero Bellaco (2 May 1866), the allied army, estimated at about 50,000 men under Argentine general Bartolomé Mitre, advanced cautiously through territory with no reliable maps and settled at Tuyutí. Marshal Francisco Solano López sought a decisive blow to force a negotiation and gathered as many soldiers as he could. The Paraguayan attack of 24 May lasted more than four hours and ended in an allied victory. From then on the Paraguayan army never again assembled a comparable force.

Tips

After heavy rain the local roads get difficult: ask at the Paso de Patria or Pilar municipality before going.
There is no shade or services on site: bring water, sunscreen and insect repellent.
If you can, add a local guide: most of the story lives in the telling, not in structures.
The battlefield is on private land: during commemorations the owner has opened access to the trenches, so outside those dates ask the Paso de Patria town hall before you go and do not enter without permission.

Open-air site. Check opening hours before you go.

Best time: Autumn and spring, with mild temperatures and dry roads.
