The Moro Crater massacre is a name given by the Americans to the final phase of the First Battle of Bud Dajo, a military engagement of the Philippine-American War which took place March 10, 1906, on the isle of Jolo in the southern Philippines. Forces of the U.S. Army under the command of Major General Leonard Wood, a naval detachment comprising 540 soldiers, along with a detachment of native constabulary, armed with artillery and small firearms, attacked a village hidden in the crater of the dormant volcano Bud Dajo. More than 600 mostly unarmed Muslim Moro villagers (including many women and children) were killed by the Americans, of whom fifteen soldiers were killed and thirty-two were wounded.
