Answer based on context:

On November 20, 1761, Captain Tiburcio Cosgaya arrived at Cisteil intending to put down the rebellion. The Indians were expecting him. In the skirmish that followed, Captain Cosgaya, five of his soldiers and eight Indians were killed. Canek told his followers that the ultimate victory of the Mayas was already written in Chilam Balam manuscripts. The governor of Yucatán sent dispatches calling up militias, and ordering Indians throughout the province to be disarmed. A major force under the command of Estanislao del Puerto and Cristóbal Calderón was sent out to surround the village to prevent reinforcements for Canek and his followers. The rebels were meanwhile preparing their defenses and attempting to expand the rebellion to nearby villages. The Spanish force of 500 soldiers met Canek and his cohorts on November 26, 1761 in the plaza of Cisteil, where 1500 Maya were arrayed in two entrenched lines. In hand-to-hand fighting, the better-armed Spanish triumphed. The village was burned, and 500 Indians were said to have perished in the blaze, including eight priests or leaders of the rebellion. Canek himself escaped with a small guard, fleeing to Huntulchac. There he assembled a force of about 300 men who had also escaped from Cisteil. But Canek and about 125 followers were then apprehended at Sibac. Canek was condemned to death, to be "tortured, his body broken, and thereafter burned and the ashes scattered to the wind."
