19 August, 1896
TODAY IN PHILIPPINE HISTORY:
The Philippine revolutionary movement is prematurely discovered by the Spaniards when the hated Fr. Mariano Gil, the curate of Tondo, breaks his vow of silence and reports about its existence and headquarters to the colonial authorities. Gil learned about the movement when he heard about it through a confession from a Filipino traitor.
In response to the mounting cruelty inflicted by the Spaniards on members of the secret revolutionary society Kataastaasang, Kagalanggalangang Katipunan nang manga Anak nang Bayan (KKK) Supremo Andres Bonifacio y de Castro (from his prison) instructs messengers to summon his leaders to a general assembly to discuss measures to counter the development.
Later, a Katipunan poster threatening the killing of the abusive Fr. Mariano Gil would appear on the poster of the Tondo church.
