As Gonzalo Pizarro was informed that the viceroy augmented his army from time to time, more especially after this successful enterprize, he resolved to march against him without delay; as hardly a day passed in which the viceroy was not joined by soldiers, horses, and arms from Spain, or some of the American colonies, all of which were landed at the port of Tumbez. He was likewise in dread lest some dispatch might arrive from the emperor, favourable to the viceroy, by which his own adherents might be intimidated, and numbers might be induced to change sides. With this view he assembled his army, determined to march in person against the viceroy, and if possible to bring him to action. He issued therefore the proper orders to all his officers, reviewed and mustered his troops, advanced them the necessary funds for taking the field, and sent off the baggage, artillery, ammunition and provisions, with the main body of the army towards Truxillo, remaining behind at Lima with some of his principal officers, to follow in proper time. About this time a vessel arrived from Arequipa with a very seasonable supply of 100,000 crowns; and another vessel from Tierra Firma, belonging to Gonzalo Martel, sent by his wife to enable him to return home. The arrival of these two vessels was very opportune for Gonzalo Pizarro, as they served to transport great quantities of musquets, pikes, ammunition, and other implements of war, together with a guard of an hundred and fifty men, and greatly facilitated the intended expedition against the viceroy.
