Hatfield–McCoy feud
Between 1880 and 1891, the feud claimed more than a dozen members of the two families. On one occasion, the governors of West Virginia and Kentucky even threatened to have their militias invade each other's states. In response, Kentucky Governor S. B. Buckner sent his Adjutant General Sam Hill to Pike County to investigate the situation. More than a dozen people died and at least 10 people were wounded. A few days after the New Year's Massacre, a posse led by Pike county deputy sheriff Frank Philipps rode out to track down Devil Anse's group across the border into West Virginia. The posse's first victim was Jim Vance, who was killed in the woods after he refused to be arrested. Philipps then made other successive raids on Hatfield homes and supporters and captured three before cornering the rest in Grapevine Creek on 19 January. Unfortunately for Philipps, Devil Anse and other Hatfields were waiting for them with an armed group of their own. A battle ensued between the two parties, and the Hatfields were eventually apprehended. Two Hatfield supporters were killed, and a deputy, Bill Dempsey, was executed by Frank Philipps after they surrendered. Wall Hatfield and eight others were arrested and brought to Kentucky to stand trial for the murder of Alifair McCoy (sometimes spelled Allaphare, Randolph's young daughter), killed during the New Year's Massacre.
Mamasapano clash
On Sunday, January 25, 2015, three platoons of the elite SAF police squad entered the guerrilla enclave of Tukanalipao, Mindanao, Philippines, with the goal of detaining two high-ranking Jemaah Islamiyah-affiliated, improvised-explosive-device experts, Zulkifli Abdhir (also known as Marwan) and Abdul Basit Usman. The SAF troops raided the hut where they believed Marwan was located, and the man they believe to be Marwan engaged them in a firefight and was killed. The SAF initially planned to take his body for identification. However, the shooting alerted the BIFF and MILF 118th Command in the area. The SAF had no time to retrieve the body so they just cut off a finger, took a photo, and left his body there. By 6:18 AM UTC+8 (PST), an SMS message was sent by the Commander of SAF 61D Battalion to SAF Director Getulio Napeñas that they were pinned down at coordinates 6.92489°N 124.52047°E. What followed was a bloody encounter that left 44 SAF, 18 MILF, and 5 BIFF dead.
