The Battle of Tirad Pass took place on December 2, 1899. 52 men of del Pilar's 60-man force were killed, including del Pilar himself. However, the Filipinos under del Pilar held off the Americans long enough for Aguinaldo's party to escape. Aguinaldo, encamped with his party about 10 km south of the pass in Cervantes, Ilocos Sur, was apprised of the result of the battle by a rider, and moved on. The party reached Banane settlement on December 7, where Aguinaldo paused to consider plans for the future. On December 16, the party departed for Abra to join forces with General Manuel Tinio. The party traveled on foot through a pass at the summit of Mount Polis, and arrived at Ambayuan the next morning. The party pushed on to Banane, pursued closely by American forces. At this point, Aguinaldo's party consisted of one field officer, 11 line officers, and 107 men. The remainder of December 1899 was spent in continuous trek.
