Answer:One important event that fueled the war of the Filipinos against the United States was the tragic Battle of Manila on February 4, 1899. It began when a nervous American sentry fired at a Filipino soldier near the San Juan Bridge, killing him. What could have been a night of uneasy peace quickly turned into chaos, as gunfire erupted and spread through the city. For many Filipinos, this was not just an exchange of shots it was the shattering of trust. After years of struggling against Spanish rule, they had hoped for true independence, but this incident made it painfully clear that the Americans had no intention of letting the Philippines govern itself. The grief and anger from that night ignited a war, turning hope into defiance.
