<P> The Mexican Constitution of 1824 liberalized the country 's immigration policies , allowing foreigners to settle in border regions such as Mexican Texas . In 1825 , American Green DeWitt received permission to settle 400 families in Texas near the confluence of the San Marcos and Guadalupe Rivers . The DeWitt Colony quickly became a favorite raiding target of local Karankawa , Tonkawa , and Comanche tribes , and in July 1826 they destroyed the capital city , Gonzales . The town was rebuilt the following year , after DeWitt negotiated peace treaties with the Karankawa and Tonkawa . The Comanche continued to stage periodic raids of the settlement over the next few years . Unable to spare military troops to protect the town , in 1831 the region 's political chief instead sent the settlers of Gonzales a six - pounder cannon , described by historian Timothy Todish as `` a small bored gun , good for little more than starting horse races '' . </P>
