The Spanish cavalry was neutralized by the Querandí bolas and the remainder of the force managed to avoid being wiped out and retreated to Buenos Aires in the night.
Further attempts at conquest and population settlement in the Pampas by the Spaniards left from three different places: Peru, Chile and Asunción in Paraguay.
From Peru, the cities of Santiago del Estero (1553), Tucumán (1565), Córdoba (1573), Salta (1582), Catamarca (1583), La Rioja (1591) and Jujuy (1593) were founded.
The Spanish conqueror Juan de Garay, who carried out the second foundation of Buenos Aires on June 11, 1580, was killed in 1583 during an ambush by Querandi people on his camp on the banks of the Carcarañá River, near the old site of Sebastian Cabots Sancti Spiritus Fort.
