The "porteños" bungled their effort to extend control over Paraguay by choosing José Espínola y Peña as their spokesman in Asunción. Espínola was "perhaps the most hated Paraguayan of his era," in the words of historian John Hoyt Williams. Espínola's reception in Asunción was less than cordial, partly because he was closely linked to rapacious policies of the ex-governor, Lázaro de Rivera, who had arbitrarily shot hundreds of his citizens until he was forced from office in 1805. Barely escaping a term of exile in Paraguay's far north, Espínola fled back to Buenos Aires and lied about the extent of "porteño" support in Paraguay, causing the Buenos Aires "cabildo" to make an equally disastrous move. In a bid to settle the issue by force, the "cabildo" sent 1,100 troops under General Manuel Belgrano to subdue Asunción. Paraguayan troops soundly thrashed the "porteños" at Paraguarí and Tacuarí. Officers from both armies, however, fraternized openly during the campaign. From these contacts the Paraguayans came to realize that Spanish dominance in South America was coming to an end, and that they, and not the Spaniards, held the real power.
