Corrected entry: There is good evidence (though not absolutely certain) that Crockett survived the battle and was executed the next day.
Corrected entry: Watch Travis after he is killed in the movie. As the Mexicans run past him, he moves his left hand out of the way.
Corrected entry: As Susannah and Angelina are escorted between Santa Anna's troops, some grime mysteriously appears on Angelina's cheek, and some of the grime on Susannah's neck disappears.
Corrected entry: At the cotillion/dance before leaving for Texas, David Crocket and the band are playing "Listen to the Mockingbird" (music familiar to fans of the Three Stooges). The Alamo took place in 1836; "Listen to the Mockingbird" wasn't published until 1855.
Corrected entry: It's not likely that the flag with "1824" on it flew over the Alamo at this time. By February 1836, most of the Anglos were fighting for an independent Texas, not for restoring the Mexican Constitution of 1824.
