Battle of Bacsil Ridge
Battle of Bacsil Ridge / San Fernando City, La Union
The Battle of Bacsil Ridge ended the month-long battle for control of San Fernando. The Japanese defenders called the Hayashi Detachment, composed of 3,000 armed troops and 2,000 unarmed support forces, took hold of San Fernando and its surrounding areas which denied entry to the port of the city and a road leading to Baguio City. As part of the San Fernando-Bacsil Operations, the 1st Battalion of 121st Infantry were sent to loosen the enemy positions starting late February with the assistance of the Allied Air Force.
The 1st Battalion made a general attack to the ridge on 16 March 1945 and fought the Japanese defenders until the capture of Bacsil on 19 March. On the same day, the 3rd battalion captured the Reservoir Hill. The Battle of Bacsil Ridge between the Filipino guerrillas and the Japanese Forces resulted in the recapture of the city of San Fernando, La Union. It was liberated on 21 March and the military offensive throughout the province ended on 24 March.
