Pedro de Rivera y Villalón, a brigadier in the Spanish army, was sent from New Mexico in 1724 on a tour to inspect the frontier defenses of New Spain. The trip, which lasted until June 29, 1728, covered more than 8,000 miles. In his diary Rivera described the location of settlements and Indians, customs and habits of the inhabitants, and the products of the soil. His engineer, Francisco Álvarez Barreyto, made a map of the Texas frontier in 1727, including detailed examinations of the coast country between La Bahía and the Neches River. Rivera's report advocated consolidation for economy, suggested a vigorous policy for the suppression of the Apaches, and recommended the removal of the La Bahía presidio (Nuestra Señora de Loreto) to the Medina River to check the Apaches in that area. His recommendation regarding La Bahía was not followed, but his report did result in the moving of three East Texas missions to San Antonio in 1731.
