Task: Question Generation
Input (English): Passage: The Guatemalan authorities were unaware of ongoing contacts between the colonial authorities in Yucatán and the Itza. In the second half of 1695 President Barrios began planning another expedition against the Itza from Verapaz, following harsh criticism of Juan Díaz de Velasco's retreat from near Lake Petén Itzá in April of that year. Barrios died in November, and oidor José de Escals became acting head of the Guatemalan colonial administration. He appointed oidor Bartolomé de Amésqueta to lead the next expedition against the Itza. Amésqueta marched his men through torrential rain from Cahabón to Mopán, arriving on 25 February 1696; the Guatemalans were still unaware of the clashes between García's forces and the Itza. Amésqueta's expedition was suffering from shortages of native labour and supplies. Twenty-five of his 150 men were sick, and his advance stalled as the force rested up at Mopán. Captain Díaz de Velasco volunteered to lead a party of 25 men ahead to the lake; he was accompanied by Dominican friars Cristóbal de Prada and Jacinto de Vargas. He was also accompanied by AjK'ixaw, the Itza nobleman who had been taken prisoner on Díaz's previous expedition, who served as a trusted guide, scout and translator. They set out from Mopán on 7 March and left some sick soldiers with some supplies after five days, they then caught up with an advance party of roadbuilders and their military escort at Río Chakal. The two forces combined, giving Díaz a force of 49 soldiers and 34 porters and archers from Verapaz. Once they arrived at IxB'ol, near the shore of Lake Petén Itzá, AjK'ixaw was sent ahead as an emissary to Nojpetén.
Output (English): Where did these forces that Diaz had come from?
