Another skirmish took place on August 26, which sent the rebels retreating toward Balara. At noon, Bonifacio and some of his men briefly rested in Diliman. In the afternoon, civil guards sent to Caloocan to investigate attacks on Chinese merchants — done by bandits who had attached themselves to the rebels—came across a group of Katipuneros and briefly engaged them. The commander of the guards, Lieutenant Ros, reported the encounter to the authorities, and the report drove Governor-General Ramón Blanco to prepare for coming hostilities. General Blanco had about 10,000 Spanish regulars and the gunboats "Isla de Cuba" and "Isla de Luzon" by the end of November.
