The outnumbered Frenchmen agreed to retreat to Louisiana. Aguayo then ordered the building of a new presidio Nuestra Señora del Pilar de Los Adaes, located near present-day Robeline, Louisiana, only 12 miles (19 km) from Natchitoches. The new fort became the first capital of Texas, and it was guarded by 6 cannon and a garrison of 100 soldiers. All six of the eastern Tejas missions were reopened, under the protection of the new presidio. Spain discouraged manufacturing in its colonies and limited trade to Spanish goods handled by Spanish merchants and carried on Spanish vessels. Most of the ports, including all of those in Texas, were closed to commercial vessels in the hopes of dissuading smugglers. By law, all goods bound for Texas had to be shipped to Vera Cruz and then transported over the mountains to Mexico City before being sent to Texas. This caused the goods to be very expensive in the Texas settlements. Because of the great distance between Los Adaes and the rest of the populated portions of Texas, the settlers in the area turned most often to the French colonists in neighboring Natchitoches, Louisiana, for trade. Without many goods to trade, however, the Spanish missionaries and colonists had little to offer the Indians, who remained loyal to the French traders. Although the Spanish settlers in the area did not encounter hostile Native Americans, since the local Caddoan-speaking peoples were friendly, the Franciscan missionaries were unsuccessful in converting the local people to Catholicism. After many years of frustration in this regard, in 1768 the College of Nuestra Señora de Guadalupe de Zacatecas, which was the sponsor of the missionaries at Los Adaes, recalled their missionaries, and the mission was closed. On November 3, 1762, as part of the Treaty of Fontainebleau, France ceded the portion of Louisiana west of the Mississippi River to Spain. With France no longer a threat to Spain's North American interests, the Spanish monarchy commissioned the Marquis de Rubi to inspect all of the presidios on the northern frontier of New Spain and make recommendations for the future. Rubi recommended that eastern Texas be totally abandoned, with all the population moving to San Antonio. With Louisiana in Spanish control, there was no need for Los Adaes to reside so closely to Natchitoches, especially after the missions had relocated to San Antonio. In August 1768, the acting governor, Juan María Vicencio, Baron de
