On 28 May 1899, there was yet another attempt to get Martín Cerezo to surrender. Again, another Spanish officer, Lieutenant Colonel Cristóbal Aguilar y Castañeda, appeared under a flag of truce and was turned away. He had brought recent Spanish newspapers, which Cerezo initially dismissed as bogus, until Martín Cerezo read an article concerning a close friend's posting, plans of which only he knew, convincing him the newspapers were genuine and that indeed Spain had lost the war. On 2 June, Martín Cerezo surrendered to the Filipinos.
