On September 1st, the people of Noveleta revolted and killed a captain and a lieutenant of the Guardia Civil and three days later the rebels penetrated to the town of Caridad, close to Cavite.
Early in September rebels were in arms, and dominating great part of the Provinces of Manila, Cavite, Batangas, Bulacan, Pampanga and Nueva Écija.

On the 9th September, the Cavite rebels attacked San Roque, which is close to the town of Cavite, and burned part of it. On the 12th, thirteen persons who had been convicted by a court-martial of complicity in the revolt were shot in Cavite.
The cables from General Blanco to the Madrid Government were all this time misleading and contradictory, and showed that he had no grasp of the state of affairs. These dispatches were subjected to severe criticism in the Heraldo, a Madrid newspaper.
By the middle of September troops arrived from Zamboanga and other southern stations, and the garrison of Manila was brought up to 6000 men, two-thirds of whom were natives. Reinforcements were sent to Cavite, for the rebels were in great force about Silang, Imus, and Noveleta.
On the 17th September another attack was made by the rebels on San Roque, but was repulsed.
On the 1st October the mail steamer Cataluña arrived with a battalion of marines from Spain, greatly to the delight of the Spaniards, who gave the force an enthusiastic reception.
Next day the ss. Monserrat arrived with more troops, and from this time forward troops kept pouring in.
Still General Blanco remained on the defensive in and around the city of Manila and the town of Cavite, and repulsed attacks made by the rebels on the magazines at Binancáyan and Las Piñas.
