The Battle of Zapote River, also known as the Battle of Zapote Bridge, was fought on June 13, 1899 between 1,200 Americans and between 4,000~5,000 Filipinos. It was the second largest battle of the Philippine–American War after the Battle of Manila five months before in February 1899. Zapote River separates the town of Las Piñas in what was then Manila province from Bacoor in the province of Cavite. The ruins of Zapote Bridge still stands next to its replacement bridge on Aguinaldo Highway.
