On the day of the victory, Brion was named admiral by Bolívar. At Margarita Island the former succeeded in winning over Juan Bautista Arismendi, the commander of the island, in which he had reduced the Spaniards to the single spot of Pampatar. On Bolívar's formal promise to convoke a national congress at Venezuela, as soon as he should be master of the country, Arismendi summoned a junta in the cathedral of La Villa del Norte, and publicly proclaimed him the commander-in-chief of the republics of Venezuela and New Granada.
