The Battle of Tuyutí was a Paraguayan offensive in the Paraguayan War. The allied victory added to the Paraguayan troubles that began with a failed offensive and continued with the loss of its fleet in the Battle of Riachuelo. In early May 1866, a Paraguayan attack at a marsh called Estero Bellaco failed. As the allies camped for over two weeks before resuming their advance, Paraguayan leader Francisco Solano López ordered a May 24 surprise attack on Tuyutí, a "a swampy, scrub-brush savannah". The Paraguayans attacked in three columns, and soon the battle turned into "a series of charges and countercharges, a Latin American version of Waterloo". The Paraguayan columns continued to attack, but never could overcome the allied firepower. Tuyutí was the last major Paraguayan attack. Ultimately, it was a devastating Paraguayan defeat: Of the 6,000 men wounded after the battle, a large percentage would die subsequently. The Paraguayan military was decimated. The May 24, 1866 battle of Tuyutí is known as the First Battle of Tuyutí; the second battle occurred on November 7, 1867, and was an indecisive and less consequential battle in which each side lost about 2,400 men.
