Soon after the arrival of Carvajal in Arequipa, the ship which, had been seized by Ribadeneyra appeared on the coast, and Carvajal was informed by some of the soldiers of Centeno who remained at Arequipa of the intention of this vessel, and of the signal which had been agreed, upon between Centeno and Ribadeneyra. Wishing to gain possession of the vessel, Carvajal concealed twenty musqueteers near the coast, and made the appointed signal. Ribadeneyra at first believed that the signal was made by order of Centeno and sent the boat on shore; but having some suspicions of the actual state of affairs, he directed the people in the boat to be extremely cautious against surprize before venturing on shore. They accordingly, refused to land, unless Centeno himself made his appearance; and as this of course could not be complied with, they returned to the ship, with which Ribadeneyra immediately set sail for Nicaragua. As no part of the late force under Centeno remained in the field, Carvajal resolved to take up his residence for some time in the city of La Plata, as he was informed that Centeno and his friends had concealed a large quantity of treasure at that place, and that he might both endeavour to discover that deposit, and might draw as large a sum as possible from the rich mines in that neighbourhood. Carvajal was willing to communicate to Gonzalo a portion of the wealth he expected to acquire in that district, for defraying the expences of the war; but he proposed especially to enrich himself on this occasion, being exceedingly covetous, as has been already remarked. He accordingly went to La Plata, which submitted without resistance, and remained there for a considerable time amassing wealth, till obliged to take the field against Mendoza.
