Patria). President Mitre ordered Conesa to recapture Corrales. Yet, on the 31st, president López sent another force of 1,200 men under the overall command of lieutenant colonel Jose Eduvigis Diaz, but further organized into three units. The first, under the command of Celestino Prieto headed for Corrales, the second under lieutenant Saturnino Viveros headed for the fort of Itapirú, while the third was held in reserve. General Conesa, with a very intrepid action, almost ambushed with full surprise a battalion led by lieutenant Celestino Prieto, with 250 men. But the noisy swamp and the Argentine troops singing wrecked the surprise and the Paraguayans fled under heavy fire. After this, general Resquin ordered commander Diaz, Viveros and Prieto to place their troops in strategic positions around the swamps for ambushing and launch counterattacks on the allied armies. 200 men under command of Diaz took the center, while 700 men of Viveros and Prieto were placed in the flanks. By nightfall, Argentine troops tried to take the village by bayonet charges, having used up all their ammunition. By 18:30, Conesa ordered a withdrawal. Aftermath Despite the victory obtained by the Paraguayans, Lopez's troops never again attempted a similar assault against the Allied Army. The Paraguayans embarked on their boats on the night of 1 February, returning to Itapirú. General Bartolomé Mitre praised the courage of the Argentine soldiers (including among the deaths Juan Serrano and Bernabé Márquez) but recommended for the next time to his troops to be "in future combats, less prodigious of their generous flame and fiery courage". The Fortress of Itapirú eventually fell on 5 April 1866. The Argentine city of Pehuajó is named in honour of its founder, Dardo Rocha, veteran who fought this battle.
