Task: Question Generation
Input (English): Passage: In a troop movement that took all night on a makeshift raft, the Texian army crossed Buffalo Bayou at Lynchburg April 19 with 930 soldiers, leaving behind 255 others as guards or for reasons of illness. The idea had been floated of leaving the Twin Sisters behind as protection, but Neill was adamant that the cannons be taken into the battle. In an April 20 skirmish the day before the main battle Neill was severely wounded, and George Hockley took command of the heavy artillery. Estimates of the Mexican army troop strength on the day of the main battle range from 1,250 to 1,500.The Texians attacked in the afternoon of April 21 while Santa Anna was still under the misconception that Houston was actually retreating. He had allowed his army time to relax and feed their horses, while he took a nap. When he was awakened by the attack, he immediately fled on horseback, but was later captured when Sergeant James Austin Sylvester found him hiding in the grass. Houston's own account was that the battle lasted "about eighteen minutes", before apprehending prisoners and confiscating armaments. When the Twin Sisters went up against the Mexican army's Golden Standard cannon, they performed so well that Hockley's unit was able to capture the Mexican cannon.The Yellowstone saw war service for the Republic one more time on May 7, when it transported Houston and his prisoner Santa Anna, along with the government Santa Anna tried to extinguish, to Galveston Island. From there, the government and Santa Anna traveled to Velasco for the signing of the treaties. Houston had suffered a serious wound during the battle, and on May 28 boarded the schooner Flora for medical treatment in New Orleans.Not until news of the victory at San Jacinto spread did the refugees return to their homesteads and businesses, or whatever was left after the destruction caused by both armies. Throughout Texas, possessions had been abandoned and later looted. Businesses, homes and farms were wiped out by the devastation of war. Often there was nothing left to go back to, but those who went home began to pick up their lives and move forward. San Felipe de Austin never really recovered from its total destruction. The few people who returned there moved elsewhere, sooner or later. Secretary of War Rusk would later commend the women of Texas who held their families together during the flight, while their men volunteered to fight: "The men of Texas deserve much credit, but more was due the women. Armed men facing a foe could not but be brave; but the women, with their little children around them, without means of defense or power to resist, faced danger and death with unflinching courage.".
Output (English): What is the first name of the person whose unit was able to capture the Mexican cannon?
