Ku dhammee weedhan soo socota: "Porteños" waxay ku fashilmeen dadaalkooda ah inay xukumaan Paraguay iyagoo doortay José Espínola y Peña inuu noqdo afhayeenkooda Asunción. Espínola wuxuu ahaa "laga yaabee ninka ugu neceb dadka reer Paraguay xilligiisii", sida uu qoray taariikhyahan John Hoyt Williams. Soo dhaweynta Espínola ee Asunción waxay ahayd mid aan aad u wanaagsanayn, qayb ahaan maxaa yeelay wuxuu si dhow ula xiriiriyay siyaasadaha hunguriga leh ee guddoomiyihii hore, Lázaro de Rivera, oo si aan kala sooc lahayn u toogtay boqolaal muwaadiniintiisa ah ilaa lagu qasbay inuu xafiiska ka baxo 1805. Isagoo si dhib leh uga baxsanaya muddadii masaafurinta ee waqooyiga fog ee Paraguay, Espínola wuxuu dib ugu laabtay Buenos Aires wuxuuna ka been sheegay baaxadda taageerada "porteño" ee Paraguay, taasoo keentay in Buenos Aires "cabildo" ay sameyso tallaabo lamid ah masiibo. Isku day ay ku doonayeen in ay arrinta ku xaliyaan xoog, "cabildo" waxay u direen 1,100 askari oo uu hogaaminayo Jeneraal Manuel Belgrano si ay ula wareegaan Asunción. Ciidamada Paraguay waxay si adag ugu jabiyeen "porteños"
Dadka reer Paraguay iyo Tacuarí. Si kastaba ha ahaatee, saraakiishii labada ciidanba waxay si cad u wada sheekeysteen intii uu socday ololaha. Xiriiradaas ayaa dadka reer Paraguay waxay ku ogaadeen in xukunkii Isbaanishka ee Koonfurta Ameerika uu soo gabagaboobay, iyo in iyaga, oo aan ahayn Isbaanishka, ay haysteen awoodda dhabta ah.
