I must get my answer from the textbook, which I do not have. Textbook is:

She, David and George Tindall. America: The Essential Learning edition. 9th ed., New York: W. W. Norton & Company, 2015.

The answer should be at least 5 sentences. I do NOT need references.

The answer is in Ch 13.

Question: Describe the Mexican army assault on the Alamo and why event was so important to the Texas revolution.
