On August 21, Katipuneros were already congregating in Balintawak in Caloocan. Late in the evening, amidst heavy rain, the rebels moved to Kangkong in Caloocan, and arrived there past midnight. As a precaution, the rebels moved to Bahay Toro or Pugad Lawin on August 23. Agoncillo places the Cry and tearing of certificates at the house of Juan Ramos, which was in Pugad Lawin. Alvarez writes that they met at the house of Melchora Aquino (known as "Tandang Sora", and mother of Juan Ramos) in Bahay Toro on that date. Agoncillo places Aquino's house in Pasong Tamo and the meeting there on August 24. The rebels continued to congregate, and by August 24, there were over a thousand.
