In 1718 Mission San Antonio de Valero was established along the San Antonio River; it was renamed The Alamo
at the start of the next century and received enduring fame in 1836 at the culmination of a period of fierce Mexican attacks during the Texan War of Independence, when around 180 defenders, made up of settlers and native Texans, held out for 13 days against up to 5,000 enemy soldiers before finally being defeated. A second mission, San José, was founded nearby in 1720, and three unsuccessful communities from the Neches River in the east were transferred 10 years later. A fort, a village and an irrigation system with dam and aqueduct were added soon after, and the communities flourished, gradually becoming augmented by other development and forming the city of San Antonio.
