During the escape, López began to discover alleged plots by his subordinates to kill him. On 27 August, three Paraguayan spies, colonel Hilario Marcó and 86 other soldiers were executed. On 7 September, the column camped near the Capiibary stream, where López ordered the death of a few more soldiers who supposedly were involved in the conspiracy. When passing through this route, the Brazilian troops found the bones and more than one hundred skulls of these Paraguayans. New battles took place between the Brazilians and Paraguayans on 21 September, in the town of San Isidoro (in the current district of Curuguaty) and on the next day, in Hurucuatí, near the town of San Joaquín, all won by the Brazilians, the latter being occupied by the troops. In pursuit of the remnants, captain Pedro Werlang reported seeing hundreds of dead people lying on the road, murdered because they were exhausted and sick. They were men, women and children, killed to avoid being captured by the Brazilians. In October, the 1st Brazilian Army Corps remained in Caraguatay and the 2nd Corps occupied San Joaquín. There were Argentine soldiers and some anti-López Paraguayans in both armies, but the Argentine forces withdrew, leaving only 800 men in that region. The few Uruguayan soldiers in Paraguay were camped on Cerro León. From then on, it was up to the Brazilians to capture Solano López.
