“I thought the same thing. I always wondered how the mexicans would have known or cared who the heck Davy Crockett was in the first place.”
FWIW, he was well known at the time, an accomplished author, even if his autobiography was ghost-written, had been on a book tour back east and arrived in Little Rock Arkansas a few months earlier and the newspapers reported hundreds of people turning out to see him.
At least one of the soldiers was related to one of the defenders and asked for and received the body to give it a burial rather than a bonfire.
Certainly the Mexican soldiers might have heard who they had killed and written about it.
I just have a hard time believing some Oaxachan conscript had ever heard of Crockett, or could attach the name to a face even if he had heard of him.
