It sucks they did that, the Moro resistance is badass though. Their suicide attackers are partly where some of the .45 stopping power mythology comes from.

From the wiki

Candidates, known as mag-sabil, “who endure the pangs of death,” were selected from Muslim youth inspired to martyrdom by the teaching of Imams. Parents were consulted before the young men were permitted by the sultan to undergo training and preparation for Parang-sabil (the path to Paradise). After an oath taken, hand on the Qur’an, the chosen took a ritual bath, all body hair was shaved, and the eyebrows trimmed to resemble “a moon two days old.” A strong band was wrapped firmly around the waist, and cords wrapped tightly around the genitals, ankles, knees, upper thighs, wrists, elbows, and shoulders, restricting blood flow and preventing the mag-sabil from losing too much blood from injury before reaching their target. Clad in white robe and turban, the chosen youth would polish and sharpen his weapons before action.[9]

At the moment of attack, the mag-sabil in Tausug would approach a large group of enemies, shout the tahlil, draw kris or barong and then rush into the group swinging his sword, killing and maiming as many victims as possible in the time he had left. The mag-sabil’s body would be washed and again wrapped in white for burial. In the unlikely event the mag-sabil survived his attack, it was believed his body would ascend to Paradise after 40 years had passed.[9]
