The Spanish learned of the French colony in late 1685. Feeling that the French colony was a threat to Spanish mines and shipping routes, King Carlos II's Council of war recommended the removal of "this thorn which has been thrust into the heart of America. The greater the delay the greater the difficulty of attainment." Having no idea where to find La Salle, the Spanish launched ten expeditions—both land and sea—over the next three years. The last expedition discovered a French deserter living in Southern Texas with the Coahuiltecans.
