The French, who were not unobservant of these Spanish acts of occupation in a country they claimed by virtue of La Salle's discovery and possession in 1684, immediately began to establish counter-settlements, on the Mississippi, and in the valley of the Red river. When Alarcon was removed from the government of Texas he was succeeded by the Marques de Aguayo, who made expeditions through the country in 1721 and 1722, during which he considerably increased the Spanish establishments, and, after this period, no attempt was ever made by the French to occupy any spot south-west of Natchitoches.
