Thirteen Martyrs of Cavite

Later that same day, the Spanish authorities declared martial law in Manila and the provinces of Cavite, Laguna, Batangas, Bulacan, Pampanga, Tarlac and Nueva Ecija.

However, the Spanish learned of the plan from a dressmaker named Victoriana Sayat and they immediately arrested Lapidario, de Ocampo and Aguado.

De Ocampo revealed the names of his companions and the thirteen suspects were rounded up on September 3 along with dozens of other Cavite leaders, including the musician Julián Felipe, who would compose the Philippine national anthem the following year.

At 12:45 p.m. the following day, the thirteen patriots were brought out of their cells and taken to the Plaza de Armas, outside Fort San Felipe, and executed by musketry.

Later, the bodies of seven of the martyrs—Máximo Inocencio, Victorino Luciano, Francisco Osorio, Luis Aguado, Hugo Pérez, José Lallana, and Antonio San Agustín—were exhumed and reburied elsewhere.

But the rest—Agapito Conchu, Máximo Gregorio, Alfonso de Ocampo, Eugenio Cabezas, Feliciano Cabuco, and Severino Lapidario remained unclaimed in their common grave.

In 1954, the capital of Cavite was transferred to a newly created city situated near the center of the province, and it was named Trece Mártires in their honor.
