Yeah, but that was about the last smart decision he made.
Santa Anna seems to have lost interest in the whole campaign shortly after the final assault on the Alamo. I wonder if the 4-10:1 kill ratio had anything to do with that. If true, the anecdotal evidence of Davey Crockett sniping at Santa Anna on a daily basis and knocking off Santa Anna's hat at least once in the attempts to kill him would also have had something to do with him losing interest.
Well, to my mind, NO historian has really explained what the hell he was doing at San Jacinto, with the Texians right out in the open, advancing on his camp, with two cannons clearly in the open, without really calling his troops to arms.
