Watch HDToday. January 22, 1932. An unprecedented peasant uprising erupts in western El Salvador, as a group of Latino and indigenous peasants cut army supply lines, attack a military garrison, and take control over several towns. Retribution is swift. After three days, the army and militias move in and, in some villages, slaughter all males over age 12. Elsewhere, they summarily execute anyone suspected of having a link to the Communists. Over the next few weeks, 10,000 people are massacred.
