Task: Question Generation
Input (English): Passage: In 1684, a council led by Enrique Enríquez de Guzmán, the governor of Guatemala, decided on the reduction of San Mateo Ixtatán and nearby Santa Eulalia, both within the colonial administrative district of the Corregimiento of Huehuetenango.On 29 January 1686, Captain Melchor Rodríguez Mazariegos, acting under orders from the governor, left Huehuetenango for San Mateo Ixtatán, where he recruited indigenous warriors from the nearby villages, 61 from San Mateo itself. It was believed by the Spanish colonial authorities that the inhabitants of San Mateo Ixtatán were friendly towards the still unconquered and fiercely hostile inhabitants of the Lacandon region, which included parts of what is now the Mexican state of Chiapas and the western part of the Petén Basin. To prevent news of the Spanish advance reaching the inhabitants of the Lacandon area, the governor ordered the capture of three of San Mateo's community leaders, named as Cristóbal Domingo, Alonso Delgado and Gaspar Jorge, and had them sent under guard to be imprisoned in Huehuetenango. The governor himself arrived in San Mateo Ixtatán on 3 February, where Captain Rodríguez Mazariegos was already awaiting him. The governor ordered the captain to remain in the village and use it as a base of operations for penetrating the Lacandon region. The Spanish missionaries Fray de Rivas and Fray Pedro de la Concepción also remained in the town. Governor Enriquez de Guzmán subsequently left San Mateo Ixtatán for Comitán in Chiapas, to enter the Lacandon region via Ocosingo.In 1695, a three-way invasion of the Lacandon was launched simultaneously from San Mateo Ixtatán, Cobán and Ocosingo. Captain Rodriguez Mazariegos, accompanied by Fray de Rivas and 6 other missionaries together with 50 Spanish soldiers, left Huehuetenango for San Mateo Ixtatán. Following the same route used in 1686, they managed on the way to recruit 200 indigenous Maya warriors from Santa Eulalia, San Juan Solomá and San Mateo itself. On 28 February 1695, all three groups left their respective bases of operations to conquer the Lacandon. The San Mateo group headed northeast into the Lacandon Jungle.
