Hi
I have just published John Wayne's Alamo which may be accessed here. It contains four chapters which summarize the Texas Revolutionary War and examines how Alamo movies have contributed to the Myth of the Alamo. These include the 1960 and 2004 ones, as well as others like The Last Command.
It may be viewed and sampled on Amazon, just follow the link.
One correspondent observed: "I'm impressed by the comprehensiveness of your reading in the Alamo literature (both history and film), and I wish you luck with the book -- not many people would have dared to try to cover so much territory."
Hope you enjoy reading it
