Battle of Tirad Pass[edit]

On December 2, 1899, American forces, who slept and rested during the night on newly harvested rice fields just below the Tirad Pass, got up and prepared for an assault of the Filipino forces fortification under the Command of General Gregorio del Pilar. On the narrow trail of Tirad Pass, the Filipino soldiers watched as their enemies began to move up the trail. On around a few hundreds yards above the pass, General Gregorio del Pilar with his staff and accompanied by two civilians from Sitio Mabatano, stood up and took his spy glass and scan it the surroundings area. He spotted the American forces as they were starting to move. But as he watched, he noticed that the American forces broke formations and instead sent a messenger on horse back with a white banner on his band. As the messenger was coming near the fortification of Filipino forces, the sound of gun was heard and the messenger fell. The American forces divided themselves into three separate groups. One group followed the trail towards the pass.

Another group ascended the hill facing the Filipino soldiers stationed in the pass. The third group, unnoticed, was led by the Filipino from the lowlands, Januario Galut, made their way up through the old trail which was hastily barricaded by falling trees a few days before the American forces arrived. This old path lead to the place where general Gregorio del Pilar stood watching, as the American forces dispersed, the general ordered the two civilians, Tucdaden and Abeng to proceed to the trenches and deliver breakfast of Filipino soldiers. All of a sudden a gunshot was heard continuously. The firing was unabated for several hours. General Gregorio del Pilar was gunned down and died. source:
