1969 (March 27): Event known as the “massacre de Cazale.” In the village of Cazale (sometimes spelled Casale or Casal), North of Port-au-Prince, army soldiers and macoutes killed several dozen peasant families. A few weeks earlier, several young, light-skinned members of the Communist Party, a political party persecuted by the regime, including Alex Lamaute and Roger Méhu, had taken refuge in this town, assuming that they would blend into a population regarded as generally light-skinned (for having harbored many Polish soldiers after the war of independence). At the same period, locals had been embroiled in a tax dispute and had refused to pay taxes on the sale of agricultural products, which had alienated the Duvalier regime further. On April 3, several macoutes arrived in the area, set several houses on fire and raped an unknown number of peasant women. The following day, after the macoutes arrested two peasant leaders opposed to taxes, the local population burned down the mayor’s office and took down the black-and-red flag of the Duvalier regime (the original Haitian flag was blue-and-red). On April 5, 500 soldiers and macoutes arrived in the area and started the killing. At the end of the day, 25 bodies were found but 80 had disappeared and were never found. This represented the largest “forced disappearance” under the Duvaliers. Several families were entirely wiped out. In addition, 82 houses had been looted and torched. Cattle was killed or taken away by looting soldiers. Women were forced to dance and “celebrate” with the soldiers who stayed in the village.
