Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Houston called for a Council of War.  The officers voted that the families should be ordered to leave, and the troops would cover the retreat. By midnight, less than an hour after Dickinson had arrived, the combined army and civilian population began a frantic move eastward, leaving behind everything they could not immediately grab and transport. Much of the provisions and artillery were left behind, including two 24-pounder cannons. Houston ordered Salvador Flores along with a company of Juan Seguin's men to form the rear guard to protect the fleeing families.  Couriers were sent to other towns in Texas to warn that the Mexican army was advancing.The retreat took place so quickly that many of the Texian scouts did not fully comprehend it until after the town was evacuated.  Houston ordered Karnes to burn the town and everything in it so nothing would remain to benefit the Mexican troops.  By dawn, the entire town was in ashes or flames.Volunteers from San Felipe de Austin who had been organized under Captain John Bird on March 5 to reinforce the men at the Alamo had been en route to San Antonio de Béxar on March 13 when approximately 10 miles (16 km) east of Gonzales they encountered fleeing citizens and a courier from Sam Houston.
