The Balangiga massacre was an incident in 1901 in the town of the same name during the Philippine–American War. It initially referred to the killing of about 48 members of the US 9th Infantry by the townspeople allegedly augmented by guerrillas in the town of Balangiga on Samar Island during an attack on September 28 of that year. This incident was described as the United States Army's worst defeat since the Battle of the Little Bighorn in 1876. Filipinos regard the attack as one of their bravest acts in the war.
