Allied troops captured the Paraguay capital city of Asunción on 1 January 1869, forcing López and what remained of his army and government to flee to the countryside. By late 1869, López was at last driven with a handful of troops to the northern frontier of Paraguay. He arrived at Cerro Corá on 14 February 1870. Two detachments were sent in pursuit of Solano López, who was accompanied by 200 men in the forests in the north, where he received news of the considerable Brazilian forces that were closing in on him. This caused some of the officials who were still with López to abandon him and approach the allied force, under the command of the Brazilian General José Antônio Correia da Câmara, which they readily joined as scouts in order to lead them to López.
