Task: Question Generation
Input (English): Passage: Four of the men deserted when they reached the Neches River. La Salle and one of his nephews became very ill, forcing the group to halt for two months. While the men recovered, the group ran low on food and gunpowder. In August, the eight surviving members of the expedition returned to Fort Saint Louis, having never left East Texas.While La Salle was gone, six of those who had remained on the Belle finally arrived at Fort Saint Louis. According to them, the new captain of the Belle was always drunk. Many of the sailors did not know how to sail, and they grounded the boat on Matagorda Peninsula. The survivors took a canoe to the fort, leaving the ship behind. The destruction of their last ship left the settlers stranded on the Texas coast, with no hope of gaining assistance from the French colonies in the Caribbean Sea.By early January 1687, fewer than 45 of the original 180 people remained in the colony, which was beset by internal strife. La Salle believed that their only hope of survival lay in trekking overland to request assistance from New France, and some time that month he led a final expedition to try to reach the Illinois Country. Fewer than 20 people remained at Fort Saint Louis, primarily women, children, and those deemed unfit, as well as seven soldiers and three missionaries with whom La Salle was unhappy. Seventeen men were included on the expedition, including La Salle, his brother, and two of his nephews. While camping near present-day Navasota on March 18, several of the men quarreled over the division of buffalo meat. That night, an expedition member killed one of La Salle's nephews and two other men in their sleep. The following day La Salle was killed while approaching the camp to investigate his nephew's disappearance. Infighting led to the deaths of two other expedition members within a short time. Two of the surviving members, including Jean L'Archeveque, joined the Caddo. The remaining six men, led by Henri Joutel,  made their way to Illinois Country. During their journey through Illinois to Canada, the men did not tell anyone that La Salle was dead. They reached France in the summer of 1688 and informed King Louis of La Salle's death and the horrible conditions in the colony. Louis did not send aid.
Output (English): What is the last name of the man who joined the Caddo on the expedition that lost its leader?
