Battle context
The Battle of Corrales, also known as the Battle of Pehuajó or Battle of Itati, was fought on 31 January 1866 during the Paraguayan War. The engagement placed Paraguayan forces under Isidoro Resquín against an Argentine force under Emilio Conesa, with Paraguay fielding approximately 1,500 troops against 2,000 Argentine soldiers. Beyond establishing that the battle occurred at this point in the war, the available record does not document its outcome or its specific effect on the broader campaign. Its multiple names suggest the engagement was recorded across different sources, but the extent of its operational consequences remains unattested in surviving documentation.
