Gregorio del Pilar

Del Pilar commanded 60 Filipino soldiers in a rearguard action at Tirad Pass to cover Aguinaldo's retreat. They held off 300 American troops for five hours. Del Pilar was killed by a shot to the neck, and his force was annihilated.

Del Pilar led Filipino forces in a successful ambush of American cavalry at Quingua, Bulacan. The attack killed Colonel John Stotsenburg and forced an American retreat. This was one of the few Filipino victories in the early phase of the war.

Aguinaldo promoted del Pilar to brigadier general at age 23, making him the youngest general in the Philippine Revolutionary Army. The promotion recognized his earlier successes in guerrilla operations against American forces in Bulacan.
