January 11, 1897 - The Thirteen Martyrs of Bagumbayan Field were executed. Among them was one of the wealthiest men of his day, Francisco Roxas. A man who refused to leverage his position of influence or to sell out his friends to save his life.

He was brought to trial at the same time as Antonio Luna, Pio Valenzeula, and others who testified against Jose Rizal.
