September 13, 1900 Battle of Pulang Lupa (TORRIJOS, MARINDUQUE):Filipino Victory
(Number of Filipino casualties unknown;
4 Americans killed, 6 wounded, 50 captured)
(Considered a milestone in Philippine history. Led by Lt. Col. Maximo Abad on the Filipino side, Capt. Devereux Shields' defeat sent shock waves through the American high command and it was considered the worst defeat suffered by the Americans during the war. This led to the first application in the Philippine-American War of population concentration in Marinduque’s six town centers, a coercive measure that finally led to Abad’s surrender on April 15, 1901).
