Magallon had witnessed the brutality and terror of World War II. However no event was ever recorded in public documents. It is believed and verified by older citizens that the opening attack of Japanese invaders were sending the two well-armed Mitsubishi Zero fighters. The Japanese commander had chosen cleverly to initiate the attack during the market day of the Magallon which is every Tuesdays; where the large population gathered and met to buy food, clothing, farm tools, and everything of value. According to witnesses, the two Japanese Zero fighters began their low level flight from Crossing Magallon all the way to the heart of Magallon that have a distance of about 7 kilometers. They strafed anything that moved in the road: people, children, and animals of all kinds. They finally dropped their two lethal cargoes of bombs right in the center of the market. After recovering from initial shock, the Japanese infantry began pouring in from every direction of the barangay.
