Important facts, incidents that took place

a. During the Spanish Occupation – During the Spanish occupation, some insurgents, to escape the Spanish tyranny and punishments, took refuge in some of the thick forests and deep caves along the river banks in Taghaban, a sitio of Bayorbor.

Destruction of Lives and Properties During World War II - During the Japanese incumbency, the town of Mataasnakahoy was occupied by Japanese soldiers. These soldiers roamed around and reached even remote barrios for food. They had frequent visits to Bayorbor, this place being about two kilometers from the town.

When the heat of the fight grew intense, the Japanese employed men to work for them. On December 5, 1944, they began to massacre all men they could take hold of. Several men from Bayorbor were victims of such horrible acts and foremost of them were the Lobrin brothers who were hit by the parachute bombs on their way home from their barrio hut; and the barrio lieutenant Mr. Benito Landicho.

People were greatly terrified by the Japanese raids and all crossed the lake and fled to the base of Taal Volcano for safety, leaving all their houses, animals, plants and all other properties at the mercy of the merciless Japs. The soldiers got the animals they could catch and slaughtered them for food. They burned houses and cut out straight woody plants such as our valuable lanzones trees, coffee and coconut trees, and used them in making their air raid shelters.
