So numerous, extensive and disastrous did these raids become that Velasquez in 1523 commissioned Rodrigo de Tamayo to organize a military and naval expedition against the Key Indians, and to kill or capture them all. This programme was not fully carried out, but it was sufficiently executed to abate the troubles and to secure peace on the coasts for several years. Tamayo's commission was renewed by Altamarino, as a matter of form, there being then no need of action; and when in the administration of Gonzalo de Guzman there was some recrudescence of hostilities, the royal government specially authorized the waging of a campaign which should bring the last of the Key Indians into subjection. The new outbreaks did not, however, prove sufficiently serious to call for or to warrant strenuous action. The scene of trouble was, however, shifted from the coast to the interior of the island. Several numerous companies of Indians, securely lodged among the mountains, began hostilities, raiding the very suburbs of Santiago itself. They were known as Cimarrons, or Wild Indians, to distinguish them from the serfs and slaves. Their pernicious activities began in 1529, and in the following year their operations were so extensive and persistent as to simulate civil war. Manuel de Rojas organized a force and led it against them with much success, and would probably have soon made an end of the troubles had he not been restrained by Guzman. The governor was probably jealous of the ability, popularity and rising influence of Rojas, and was not willing that he should gain the prestige which complete victory would confer upon him. So he called him back in circumstances which would, he thought, discredit Rojas and make his campaign seem a failure. Vadillo during his brief administration sought to end the troubles by pacific and conciliatory overtures, but failed. It was thus left for Rojas, on becoming governor in succession to Guzman, to take up again the work from which he had been recalled by his predecessor. This he did to much effect at the end of 1532. He sent a strong force against the mountain fastness of Guama, the foremost chieftain of the Cimarrons, and completely defeated him, putting him to flight and almost extirpating his band. Shortly after this victory of Rojas's, Guama was killed by one of his own few remaining followers. Rojas then sent his troops to disperse Cimarron bands near Bayamo, and Baracoa, which they did with much success, so that peace and security were pretty well restored throughout the island.
