Continuity: When Crockett's party first see San Antonio, they are carrying little more than blanket rolls on their horses - and no pack mules. However, when Crockett tells them to change into their best duds, top hats and other clothes appear from nowhere.

Factual error: The facade of the chapel is slightly anachronistic: the two upper windows were not added until the 1840's, and the top was more level - for the movie, it was deliberately distorted to suggest the famous hump by which people recognize the Alamo today. The chapel itself was built to scale, but the rest of the compound is about 75% as big as the original - otherwise, the Alamo compound is generally quite accurate.

Factual error: Colonel Fannin's men were massacred after the siege of the Alamo, not before. The most likely reason Fannin never got to the Alamo with reinforcements was simply that he was afraid of Santa Anna's giant army and ruthless tactics.

Plot hole: At the start of the final battle, the Mexican artillery is lined up wheel to wheel, and fires the opening salvo. Apparently Newton's third law doesn't apply in Texas, because none of the cannon recoil after firing.

Visible crew/equipment: During the battle scene, you can see stuntmen falling on mattresses. Just after Crockett tells his men to take Bowie into the chapel, someone actually falls off of a wall and bounces.

Factual error: Houston sent Bowie to San Antonio with orders to blow up the Alamo and withdraw to Gonzales. It was Bowie's idea (not Travis's) to stay and fortify the Alamo.

Factual error: Travis calls Susannah Dickinson his "cousin." They were not related. And Susannah would have been about 15 years old, with black hair, while her daughter, Angelina, was about 15 months.

Plot hole: When Travis makes his speech offering the men a chance to leave the Alamo, and opens the Alamo's gates, Bowie and Crockett are about to leave with their men. Yet it is broad daylight and the fort is already surrounded. Where is anyone going to go?

Factual error: There is good evidence (though not absolutely certain) that Crockett survived the battle and was executed the next day.

Factual error: After the altercation between Bowie and Travis, Davy Crockett informs Travis that he had only fought Indians, except for fighting the British. Nowhere in Crockett's biographies does it indicate he participated in any battles against British troops.
