Battle of Villa Verde Trail

The Battle of Villa Verde Trail (Filipino: Labanan sa Tugaygayan ng Villa Verde) was a campaign by the United States Army and Filipino guerrillas in the Philippines during World War II in 1945 to force its way across the Caraballo Mountains from the Central Luzon plain to the Cagayan Valley. Somewhat to the surprise of the Americans, the Japanese had constructed strong defenses along the narrow and winding Villa Verde Trail, 27 miles (43 km) in length.
