The Battle of Tuyutí was a Paraguayan offensive in the Paraguayan War targeting the Triple Alliance encampment of Tuyutí. It is considered to be the bloodiest battle to happen in South America; the result of the battle was an allied victory which added to Paraguayan troubles that began earlier with failed offensives and the loss of its fleet in the Battle of Riachuelo. Another attack on the allied camp was made in November 1867. In this phase of the war the Allies' strategic objective was to take the Fortress of Humaitá, the gateway to Paraguay, they intended to launch an amphibious operation, which required their land forces to take the fortress from the rear. After crossing the Paraná River from Argentina and landing in Paraguay, they had a long march across country studded with lagoons and carrizal; the fortress was defended by the extensive earthworks of its Quadrilateral design. It was in this context. In early May 1866, the Paraguayan attack at the Estero Bellaco marsh failed; the allies camped for over two weeks before resuming their advance on 20 May 1866.

Paraguayan leader Francisco Solano López moved his headquarters to Paso Pucu, where he dug trenches in the passes from Gomez to Rojas. After learning that the Allied army were planning to attack on the 25th, Lopez ordered a surprise attack on Tuyutí, "a swampy, scrub-brush savannah", for the 24th; the 24 May 1866 battle of Tuyutí is known as the First Battle of Tuyutí. The Paraguayans attacked in three columns at 11:55. Gen Vincente Barrios, with 8,000 infantry and 1,000 cavalry attacked the Allied left, which were Brazilians under the command of Gen. Osorio. Gen. Isidoro Resquín, with 7,000 cavalry and 3,000 infantry attacked the Allied right flank. Col. Jose Diaz with 6,000 infantry and 1,000 cavalry attacked the Allied center, Gen. Flores' Vanguard Division. Col. Hilario Marco, with 7,000 men and 48 cannons, formed the reserve at Estero RojasThe attack began in the center, where the Uruguayans were forced back along with some Brazilian Volunteer battalions. On the left of the Allied encampment, Captain Emilio Mallet had ordered the construction of a large moat in front of his artillery pieces.

When the Paraguayan onslaught reached it, they were in grapeshot range and unable to cross the obstacle. The Paraguayans tried to circle the artillery, avoiding the incoming fire, but encountered Antonio Sampaio's 3rd Infantry Division; this unit fought in the muddy terrain though their commander died in the process. At this point, Osório ordered his reserves to repelled the Paraguayan center. On the allied left, the Paraguayans forced back the few Brazilian units reaching the Allied camp. Osório reinforced the Brazilian lines with various units committing the 2nd Cavalry Division, commanded by General Mena Barreto; the Paraguayans continued to attack until they were annihilated. In the Argentine sector, the Paraguayan cavalry under Gen. Resquín routed the Argentine cavalry under Gens. Caceres and Hornos. Soon the battle turned into "a series of charges and countercharges, a Latin American version of Waterloo"; the Paraguayan columns could not overcome the allied firepower. In the words of Colonel Thompson of the Paraguayan army, "At 4 p.m. the firing was over, the Paraguayans being defeated, their army destroyed.

The Allies had suffered also, but they still had an army left. The Paraguayans left 6,000 dead on the field; this was because the Paraguayans would never surrender but, when wounded, fought on till they were killed. 7,000 wounded were taken into the Paraguayan hospitals from this battle, those with slight wounds not going into hospital at all.... The Allies lost above 8,000 killed and wounded." As result of the battle, each side's losses were as follows: There have been contradictory reports about the casualty numbers and debates over the true values. Centurión, reported that Paraguayan dead numbered about 5,000, maybe more, the wounded 7,000, while the allies lost 8,000 killed and wounded. Thompson claimed that 6,000 were killed. Other authors give different numbers: in Barreto's opinion 6,500 Paraguayans were killed, while allied casualties were 3,647, with 3,011 Brazilians. According to Silva Pimentel 7,000 Paraguayans were killed. Rawson and Beverina declared that 7,000 Paraguayans were killed along with "so many others wounded", while the allied casualties were 4,000.

Osorio's Order of the Day affirmed that the Paraguayan dead numbered "more" than 3,000, with 200 wounded and 21 prisoners. Tuyutí was the last major Paraguayan attack, it was a devastating Paraguayan defeat. "The 10,000 men who had not been killed or wounded were scattered and disorganised, it was some days before they were again collected", wrote Thompson. "The Allies buried some of their own dead, but they heaped up the Paraguayan corpses in alternate layers with wood, in piles of from 50 to 100, burnt them. They complained that the Paraguayans were so lean they that they would not burn"; the largest battle fought in South America was over. Lopéz's flanking maneuver had failed, but it had come close to succeeding. In fact, the Allies were unable to pursue the enemy, they needed to rebuild. The Allied forces stayed in their camp until September, but disease struck the camp, claiming some 10,000 victims. After September, advances were litt
