Pata Island massacre

The Pata Island massacre refers to an event that took place on February 12, 1981, on Pata Island, Sulu province in the Philippines. More than 100 Philippine Army officers and men were killed by Moro natives in what was called by retired Major General Delfin Castro as "the biggest number of casualties incurred by the Armed Forces of the Philippines in a single incident since the start of the conflict in Mindanao and had the dubious distinction of achieving the biggest losses in AFP firearms and equipment in a single incident." An estimated 3,000 Tausug civilians, including women and children, were killed in months of shelling by military forces in 1982 and was tagged as the Pata Island massacre. The 1st Infantry Division of the Philippine Army conducted an operation on Pata Island on February 9, 1981, after receiving reports of landings being made there by Moro National Liberation Front elements. The 31st Infantry Battalion was at the forefront of this operation, assisted by two other battalions. After being assured by local barangay leaders that no MNLF forces had landed, the 31st Infantry Battalion began to withdraw its troops from the island on February 12, 1981, leaving its Headquarters Service Company along with battalion commander Lieutenant Colonel Jacinto Sardual. Lt. Col. Sardual called on a Civilian Home Defense Forces commander Unad Masillam before his planned departure. Masillam and his men then accompanied Sardual back to the Headquarters Service Company's encampment, at which point Masillam asked Sardual to form up the company and stack up their weapons so that both sides could conduct a farewell ceremony. Sardual, who was a dental officer, complied and gave the order for his men to do so. The Moros surrounded the government troops and then opened fire using automatic rifles. Responding soldiers who later discovered the bodies of their dead comrades reported finding spent .30 caliber shell casings and links at the Moros' firing positions, indicating the use of machine guns.
