"Laredo is on the Rio Grande in southwestern Webb County in South Texas, about 150 miles southwest of San Antonio and 135 miles west of Corpus Christi. It is served by Interstate Highway 35, U.S. highways 59 and 83, State Highway 359, Ranch Road 1472, and the Missouri Pacific and Texas Mexican railroads. This cosmopolitan city is a major port of entry for international trade and tourism between the United States and Mexico... During the Texas Revolution Laredo served as a concentration point for the forces of Antonio López de Santa Anna. After the war, Texas leaders generally considered the Rio Grande to be the southern boundary of the new Republic of Texas, but they made no effort to extend jurisdiction over the border region. The residents of Laredo continued to consider themselves citizens of the Mexican state of Tamaulipas... No effort was made to place Laredo under the jurisdiction of Texas until the Mexican War... The establishment of the Rio Grande as the international boundary divided the town of Laredo, many of whose residents had homes and ranchos on the right bank (in Mexico). A number of other families who did not wish to live under the American flag chose to move across the river to what became the village of Nuevo Laredo, Tamaulipas.
