I agree with 2damendfan.
My family fought that war. I have the land grants from the republic, and the State of TX to prove it.
My Great Great Great grandfathers (both sides of the family) rode with Juan Sequin, fought at Concepcion, and the Siege of Bejar. A cousin was at San Jacinto.
The rising of the Tejanos was due to a formerly Constitutional government becoming centralized and dictatorial. The flag they fought under carried the date 1824, which relates to a demand to restore governmental control to constitutional parameters.
This isn't politics, it is history.
The Alamo is a sacred shrine to the strength of a few men to stand up for what was right.
Yes it was foolish on the part of Travis to think he could defend the site, when just a few months earlier, Seguin had run the entire Mexican Army out of the place forcing Gen'l Cos to surrender, give parole, and leave Tejas, but then we would not have the things of which legends are made.
When taking the tour of the Alamo, listen to the Docents as they describe what was happening at different parts of the area. Walk to the outer borders of the encampment (across the street) and sit under the large oak tree, contemplating that morning of March 6, 1836. Go to the nearby Cathedral, and view the resting place of the Alamo Defenders, where their remains were taken after the Battle. Crocket, Bowie, Travis and others are there in a marble container just inside the doors of the Chapel.
Travel to Bahia, and learn what happened to the defenders there, and learn of Fannin's fate, and the brutality of the Enemy.
Remember the Alamo, Remember Goliad.
