[5] In February 1997, Villar Foundation, local governments of Bacoor, Cavite and the City of Las Piñas, the National Centennial Movement, and the Department of Education organized an event to pay tribute to the centennial year of the Battle of Zapote Bridge.

In retaliation, the Sixth artillery under Lieutenant Benjamin M. Koehler fired back six shrapnel shells from two 3.2-inch (81 mm) guns.

Major Starr signaled the gunboats for support, which responded with men and ammunition from the Helena and Monadnock.

[3] Near the Zapote Bridge, General Samuel Ovenshine moved his artillery on the road, flanked by his infantry.

Upon moving on to the enemy, the fire opened furiously to-and-fro the Filipino trenches and breastworks south of the bridge.

[11] After hours of heavy fighting, between 4 and 4:40 pm, the Filipinos gave way, abandoning their positions and began falling back.

He sent forward a company from the 21st Infantry headed by First Lieutenant William M. Morrow to ascertain the positions of the enemies and found them 1 mile south of the bridge.

Consequently, the Philippine Army began using tactics of guerrilla warfare, avoiding a decisive battle and reverting to harassment.
