Another good one is "Three Roads to the Alamo" by William C. Davis. It tracks the lives of Bowie, Crockett and Travis and how these three legendary lives all converged at the Alamo. It explodes many myths and provides documentary proofs (an amazing number of Bowie's fraudulent land claims survive, complete with his handwriting and misspellings.) Perhaps most disheartening, he probably only used a knife in a single fight, the Sandbar duel. The rest was newspaper hype, just like now. Bowie comes off as a charming rogue, a man of questionable ethics but undeniable courage and loyalty to his friends.
