In 1792 events related to the mission led to a Huilliche uprising that year. According to Diego Barros Arana "an Indian" called Felipe was said to have obtained a letter from the Governor of Valdivia to the head of the mission.[2] This letter would have revealed that the purpose of the mission was to "lull the Indians in the confidence of peace, to give death to their warriors and reduce more easily the peoples into slavery".[2] Albeit these claims are deemed false by Barros Arana in 1792, they were enough to ignite an uprising.[2] The uprising begun in September 1792, with a series of assaults against Spanish settlers in Río Bueno and Lago Ranco.[2] Houses were torched and animals stolen. Ten Spanish settlers are reported to have been killed.[2]Friar Antonio Curcoa (or Cuzcoo) who ran the mission was "tied naked to the tail of a vigorous horse and dragged around in the countryside until he ceased to exist".[3][4]
