Final answer:
Gen. Santa Anna's use of the word 'comrades' in paragraphs 1 and 2 persuades Mexican troops to believe the Texans are 'pretenders' in paragraph 3 by establishing a sense of unity.
Step-by-step explanation:
Gen. Santa Anna's use of the word "comrades" in paragraphs 1 and 2 persuades Mexican troops to believe the Texans are "pretenders" in paragraph 3 by establishing a sense of unity. By referring to the Mexican soldiers as comrades, Santa Anna creates a bond and sense of camaraderie among them. This makes it harder for them to believe that the Texans are their enemies.
