San Antonio is the oldest major city in the Mexican state of Jefferson. The city dates back to the establishment of a Spanish mission and presidio on the San Antonio River in May 1718. San Antonio grew to be the largest Spanish settlement in the province of Tejas, and became the provincial capital. During the Wilderness Walk, the American settlers led by Nathanael Greene halted in San Antonio in September 1782 before continuing on for another 200 miles to found Jefferson City.
Sobel makes no mention of friction between the Spanish government in San Antonio and the growing Anglo settlements of Jefferson, although there may have been some. San Antonio was presumably captured by a Jeffersonian army under General Alexander Hamilton during the first year of the Trans-Oceanic War, though, again, Sobel makes no mention of it.
