On December 8, 1720, Dalasi, the Datu of Butig (also known as Rajah "Janatun" of Butig), with an armada of one hundred vessels or “paraws” manned by Sultan sa Kanluran, "Miyangaludan" and several thousand Moros, attacked Fort Pilar in Zamboanga. He captured a local Jesuit priest and forced the Spanish government in Manila to give ransom payment in exchange for his freedom. (Hurley, 1936) But the accuracy of this report by Hurley is in doubt considering the distance of Butig (Lanao del Sur) to the shores of Zamboanga. Furthermore, the Jesuits in Zamboanga were more engaged with the Tausugs of Sulu; and for Datu Dalasi, a Maranao of Lanao, to get involved in the affairs of the Sulu Sultanate is highly unusual.
