The Battle of Tirad Pass, was a battle in the Philippine–American War fought on December 2, 1899, in northern Luzon in the Philippines, in which a 60-man Filipino rear guard commanded by Brigadier General Gregorio del Pilar succumbed to more than 500 Americans, mostly of the 33rd Volunteer Infantry Regiment under Major Peyton C. March, while delaying the American advance to ensure that President Emilio Aguinaldo and his troops escaped.
In honor of Del Pilar's heroism, the Philippine Military Academy was named Fort Del Pilar and a historical marker placed at the site of the battle.
