Urged by two influential Jesuit priests who had come to Brazil with Mem de Sá, named José de Anchieta and Manuel da Nóbrega, and who had played a big role in pacifying the Tamoios, Mem de Sá ordered his nephew, Estácio de Sá to assemble a new attack force. Estácio de Sá founded the city of Rio de Janeiro on 1 March 1565 and fought the Frenchmen for two more years. Helped by a military reinforcement sent by his uncle, on 20 January 1567 he imposed final defeat on the French forces and decisively expelled them from Brazil, but died a month later from wounds inflicted in the battle.
