Formerly named Concepcion (in honor of its patron saint, Nuestra Senora de Concepcion), it was renamed after general Gregorio del Pilar by virtue of Republic Act No. 1246 on June 10, 1955,[5] sponsored by Congressman Ricardo Gacula. The municipality was the site of the Battle of Tirad Pass where General del Pilar fought to the death against the Americans.


The town got its name after general Gregorio del Pilar.


Battle of Tirad PassEdit

On December 2, 1899, American forces, mostly of the 33rd Volunteer Infantry Regiment under Major Peyton C. March, 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 the enemy 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, spotted the American forces through his spy glass as they were starting to move. But as he watched, he noticed that the American forces broke formation and instead sent a messenger on horse back with a white banner. As the messenger was coming near the fortification of Filipino forces, the sound of a gun was heard and the messenger fell. The American forces divided 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, led by a Filipino from the lowlands named Januario Galut, made their way up unnoticed through the old trail which was hastily barricaded by felled trees a few days before the American forces arrived. This old path lead to the place where General 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 the breakfast of the Filipino soldiers. All of a sudden continuous gunshots were heard continuously and went unabated for several hours. General del Pilar was shot and killed.


The town lies among the western hills of the Cordilleras in the interior eastern portion of the province of Ilocos Sur. It is bounded in the north by the town of San Emilio, Quirino in the east, Sigay in the south and Salcedo in the west. Its 7 barangays and sitios are connected by winding foot trails and seasonal rugged roads. The town is likewise endowed with natural scenery and wonders such as the payoh or rice terraces, pristine waterfalls, and the distinctive peak of Mount Tirad. There are also trails crisscrossing Tirad Pass, which were built through polo y servicio (forced labor) during the Spanish Period.
