In the course of their expedition they asserted that they had penetrated six hundred leagues to the eastwards of La Plata, through a champaign country of very easy access, and tolerably abounding in provisions and water.  Bermudez added, that within a very few days they had learnt, from some Indians who occasionally traded into the province of Las Charcas, of the revolt which had taken place in Peru, but had been unable to procure information respecting the causes of this insurrection or as to who were chiefly engaged in it; for which reason he had been sent on before to inquire into these circumstances, and had received orders from the captains and other principal persons in the expedition, to offer their services to the party that acted for the royal interests, in which cause they might be of material importance, as they had a considerable number of excellent horses and plenty of arms.  After the conclusion of this narrative, Mendoza gave Bermudez an account of all the late events in Peru; on which, in, virtue of the commission with which he had been entrusted, Bermudez promised in the name of all his companions to march against the lieutenant-general.
