The rebellion in Corrientes, which was initially defeated, was led by Pedro Eugenio Aramburu, who later became one of the main players of the future government. Two rebel destroyers, that were enforcing the blockade of the Río de la Plata, were strafed by loyalist aircraft and suffered some casualties. The city of Mar del Plata was subjected to naval bombardment on 19 September by the light cruiser ARA "9 de Julio" and several destroyers, and scattered skirmishes and air strikes took place elsewhere, including Buenos Aires itself.
