Reality: Perhaps the most famous battle in U.S. history is the fall of the Alamo. “Remember the Alamo!” as the saying goes. General Santa Anna and his Mexican army slew all of the Alamo’s defenders the morning of March 6, 1836, but not all of those inside the Alamo’s walls died. Around a dozen women and children survived. They were present during the 12-day siege, and they were spared as non-combatants.
