Another view of the Alamo

I bet this sort of thing is old hat for the historically minded, but given how much hoorah we make of the Alamo here in Texas, it's instructive to read this Straight Dope take on the event.

In this version, the Mexicans took such heavy losses only because of really bad leadership, and nobody comes out looking good. Meanwhile the defenders were disorganized, had not stored enough food for a siege, and didn't have enough men to defend the fort, which was "of little strategic value" anyway.

Do any wargames allow an Alamo? Suppose you set up a site that has emotional significance but doesn't cost you many resources, and it gets toasted. You could get morale bonuses later. I'm not aware of any games that do this, but I'd love to hear about one.
