Mexico starts to get angry and shuts down the border for US Citizens to come into Texas. Now, both Mexico and the US Pioneers are mad.
The Mexican Army finally get so mad that they decide to just kick the Pioneers off their land and they decide to do it by force because the Pioneers wouldn't get off any other way.
This is the first battle. The Mexicans highly outnumbered the Americans 6,000 to 150. The Americans took base in the Alamo, a church where every single one of them were slaughtered. This made America angry and fight back much harder to eventually win the war.
