In the early 1720s the Comanche began trading with the French. After the French arranged a peace between the Comanches and Wichita in 1747 (reconfirmed in 1750), the exchange of French trade goods for Comanche horses expanded rapidly. In Texas the Comanche and Wichita defeated a Spanish expedition in 1759 in the Battle of the Two Villages. The Spanish in New Mexico also became alarmed, as the Comanches were now armed with French firearms, which they paid for with horses and mules stolen in New Mexico. Beginning with the Comanche raid on Pecos in 1746, New Mexico was under siege. For the next forty years Comanche raids struck virtually every place in Spanish New Mexico. Both Taos (1760) and Pecos (1746, 1750, 1773, and 1775) were attacked by the Comanche. Some of the Comanche continued to trade peacefully, as the Comanche were not a unified tribe, but several independent divisions, each with the power to make war or peace.
