The Balangiga bells are three church bells taken by the United States Army from the town church of Balangiga, Eastern Samar in the Philippines as war booty after reprisals following the Balangiga massacre in 1901 during the Philippine-American War. One church bell is in the possession of the 9th Infantry Regiment at Camp Red Cloud, their base in South Korea, while two others are on a former base of the 11th Infantry Regiment at F. E. Warren Air Force Base in Cheyenne, Wyoming. At least one of the bells had tolled to signal the surprise attack by the Filipinos while the Americans were eating breakfast. The attack claimed the lives of more than forty soldiers of the US garrison posted in the town, and in reprisal the US army killed every male over the age of 10 years, during which the bells were taken.
On September 28, 1901, Filipino freedom fighters from the village of Balangiga ambushed Company C of the 9th U.S. Infantry Regiment, while they were at breakfast, killing an estimated 48 and wounding 22 of the 78 men of the unit, with only four escaping unhurt. The villagers captured about 100 rifles and 25,000 rounds of ammunition. An estimated 20 to 25 of the villagers had died in the fighting, with a similar number of wounded.
In reprisal, General Jacob H. Smith ordered that Samar be turned into a "howling wilderness" and that any Filipino male above ten years of age capable of bearing arms be shot. From the burned-out Catholic town church, the Americans looted three bells which they took back to the United States as war booty. The 9th U.S. Infantry Regiment, however, maintains that the single bell in their possession was presented to the regiment by villagers when the unit left Balangiga on April 9, 1902. Smith and his primary subordinate, Major Littleton Waller of the United States Marine Corps were both court-martialled for illegal vengeance against the civilian population of Samar. Waller was acquitted of the charges. Smith was found guilty, admonished and retired from service.
