[Q]: Context: However, the Seven Years' War ended on February 10, 1763 with the signing of the Treaty of Paris in Paris, France. Also, Silang was assassinated on May 28, 1763 by an Indio under the employ of the friars. The Spanish were then able to focus on the uprising and mustered forces to surround Palaris.

By September 1763, news of the peace treaty reached Pangasinan and army of Palaris' men surrendered and returned to normal life amid the Spanish offensive. Palaris tried to fend off the offensive at the village of Mabalitec near the Agno River between Binalatongan and Bayambang in December 1763.
