During the Spanish American War, Aguinaldo returned to the Philippines and established the government of the First Philippine Republic. He appointed del Pilar section leader of the revolutionary forces in Bulacan and Nueva Ecija. On June 1, del Pilar landed in Bulacan with rifles purchased in Hong Kong, quickly laying siege on the Spanish forces in the province. When the Spaniards surrendered to del Pilar, he brought his men to Caloocan, Manila to support the other troops battling the Spaniards there.

4. Death of Gregorio Del Pilar Main article: Battle of Tirad Pass On December 2, 1899, del Pilar led 60 Filipino soldiers of Aguinaldo's rear guard in the Battle of Tirad Pass against the "Texas Regiment", the 33rd Infantry Regiment of the United States led by Peyton C. March. A delaying action to cover Aguinaldo's retreat, the five-hour standoff resulted in Del Pilar's death due to a shot to the neck (at the height or end of the fighting, depending on eyewitness accounts). Del Pilar's body was later despoiled and looted by the victorious American soldiers.[3] Del Pilar's body lay unburied for days, exposed to the elements. While retracing the trail, an American officer, Lt. Dennis P. Quinlan, gave the body a traditional U.S. military burial. Upon del Pilar's tombstone, Quinlan inscribed, "An Officer and a Gentleman". In 1930, del Pilar's body was exhumed and was identified by the gold tooth and braces he had installed while in exile in Hong Kong.
