In 1834, his book was published titled: A Narrative of the Life of David Crockett. In 1835 he was again defeated for re-election: Saying, "You may all go to hell, and I will go to Texas," he did just that, joining the Texas Revolution.
He took part in the Battle of the Alamo (February 23 - March 6, 1836) and for many years was believed to have gone down fighting there. Evidence has come to light since 1955 that makes it likely Crockett was one of the half dozen or so men taken prisoner after that battle and summarily executed by General (later President of Mexico) Antonio de Santa Anna.
One of his sayings, which were published in almanacs between 1835 and 1856 (along with those of Daniel Boone and Kit Carson) was, "Be always sure you are right, then go ahead." In 1954 his legend was again popularized by Walt Disney, who made four movies and a television series about him (starring Fess Parker); the Ballad of Davy Crockett and coonskin caps like the one he wore in those films were all the rage for young boys for a time. After that fad had waned, John Wayne starred as Crockett in the 1960 feature film The Alamo (the first film he also directed).
In the movies Crockett has also been played by Charles K. French (1909), Dustin Farnum (1916), Cullen Landis (1926), Jack Perrin (1937), Lane Chandler (1937), Robert Barrat (1939), George Montgomery (1950), Trevor Bardette (1953), Arthur Hunnicutt (1955), James Griffith (1956), Brian Keith (1987), Johnny Cash (1988), Tim Dunigan (1988 & 1989), David Zucker (1991), John Schneider (1995), Scott Wickware (2000), Justin Howard (2002) and Billy Bob Thornton (2003).
Davy Crockett was also the name given to a small nuclear weapon that was deployed by the U.S. during the Cold War. See: Davy Crockett (nuclear device)
