The Oakwood mutiny occurred in the Philippines on July 27, 2003. A group of 321 armed soldiers who called themselves "Bagong Katipuneros" (Filipino: New Katipuneros) led by Army Capt. Gerardo Gambala and LtSG. Antonio Trillanes IV of the Philippine Navy took over the Oakwood Premier Ayala Center (now Ascott Makati) serviced apartment tower in Makati City to show the Filipino people the alleged corruption of the Gloria Macapagal-Arroyo administration. They also stated that they saw signs suggesting that the President was going to declare martial law.
The group was dubbed "Magdalo" by the press, in a reference to the insignia they adopted during the incident—the perceived flag of the Magdalo faction of the Katipunan during the Philippine Revolution. Sources conflict on whether the eight-rayed-sun version of the flag was used by the Magdalo faction, the sixteen-rayed-sun version of the flag was used by the Magdiwang faction, or vice-versa.
