Forget the Alamo: The Rise and Fall of an American Myth by Bryan Burrough, Chris Tomlinson, and Jason Stanford:
Walt Disney’s Disneyland debuted on ABC on a Wednesday evening, October 27, 1954, and proved an immediate hit. When the producers proposed an episode based on Crockett, Disney was skeptical. Crockett was no longer what you would call a household name. The writers, though, crafted a story line Disney could not resist. The trick was to treat all of Crockett’s boasts as fact, and then make his death at the Alamo the climax of a three-part miniseries. Part one would focus on Crockett’s time killing Native Americans, and of course bears, the next would cover his time in Washington, and the final episode would end with glory at the Alamo. The miniseries showed little resemblance to the facts of history, but there was no doubt it was a great story, that of an honest man betrayed by the world who nevertheless sacrificed himself so others might live. If that sounds a little familiar, a little, shall we say, biblical, well, that was very much on purpose.
