As Pedro Martin, the provost-marshal, strongly suspected that some of those who accompanied Carvajal had participated in this plot; he endeavoured to discover this by torturing Francisco de Guzman, one of the prisoners. Finding that Guzman made no confession on this head, he interrogated him particularly respecting a soldier along with Carvajal named Perucho de Aguira, and some of his friends, demanding to know whether these men were in the secret. On purpose to free himself from the torture, Guzman said they were. After this confession, Guzman was formally condemned to become a monk in the convent belonging to the order of mercy, in which he accordingly assumed the habit. After this, Martin demanded from the registrar a certificate of the confession of Guzman, by which Aguira and others were implicated in the plot, and Martin immediately sent off this writing by an Indian messenger to Carvajal who was then at Guamanga. On the receipt of this paper, Carvajal ordered Aguira and five others to be hanged, without any further proof or examination. A short time afterwards, the registrar being sensible of the error he had committed in supplying the certificate, sent off a full copy of the confession made by Guzman, in which was an ample revocation of all he had said under torture, declaring that he had falsely charged Aguira and the others, merely to get free from torture. This was however of no avail, as it arrived too late, Aguira and the others having been already executed, although they asserted their innocence to the last moment of their lives, as was certified by the confessors who attended them at their execution; but Carvajal was inexorable.
Learning while at Guamanga, that Centeno had retired through the desert to Casabindo as he was unable to cope with Toro, Carvajal was satisfied that the affaire of the insurgent party were in a fair train in Las Charcas, where his presence was not now needed, and determined therefore to return to Lima. He was besides induced to take this step in consequence of a difference which subsisted between Toro and himself, occasioned by the charge of lieutenant general under Gonzalo having originally belonged to Toro, of which he had been deprived in favour of Carvajal. He feared therefore, lest Toro, on his victorious return from Las Charcas, being at the head of a much stronger force, might renew their former quarrel. Carvajal had likewise received letters from some inhabitants of Lima, remarking the lukewarmness of Aldana to the cause of Gonzalo Pizarro, and requesting his presence to place affairs at that city on a more secure footing. He returned therefore to Lima; but learning shortly afterwards the successful return of Centeno against De Toro, he again collected his troops and prepared to march against Centeno. With this view, he had his standards solemnly consecrated, not forgetting to impose fresh exactions on the inhabitants of Lima. On this occasion, he designated his army, _The happy army of Liberty, against the Tyrant Centeno._
