Thus, in 1545, the reign of an attractive and vigorous personality was brought to an abrupt close.  Manco left three young sons, Sayri Tupac, Titu Cusi, and Tupac Amaru.  Sayri Tupac, although he had not yet reached his majority, became Inca in his father’s stead, and with the aid of regents reigned for ten years without disturbing his Spanish neighbors or being annoyed by them, unless the reference in Montesinos to a proposed burning of bridges near Abancay, under date of 1555, is correct.  By a curious lapse Montesinos ascribes this attempt to the Inca Manco, who had been dead for ten years.  In 1555 there came to Lima a new viceroy, who decided that it would be safer if young Sayri Tupac were within reach instead of living in the inaccessible wilds of Uilcapampa.  The viceroy wisely undertook to accomplish this difficult matter through the Princess Beatrix Coya, an aunt of the Inca, who was living in Cuzco.  She took kindly to the suggestion and dispatched to Uiticos a messenger, of the blood royal, attended by Indian servants.  The journey was a dangerous one; bridges were down and the treacherous trails were well-nigh impassable.  Sayri Tupac’s regents permitted the messenger to enter Uilcapampa and deliver the viceroy’s invitation, but were not inclined to believe that it was quite so attractive as appeared on the surface, even though brought to them by a kinsman.  Accordingly, they kept the visitor as a hostage and sent a messenger of their own to Cuzco to see if any foul play could be discovered, and also to request that one John Sierra, a more trusted cousin, be sent to treat in this matter.  All this took time.

In 1558 the viceroy, becoming impatient, dispatched from Lima Friar Melchior and one John Betanzos, who had married the daughter of the unfortunate Inca Atahualpa and pretended to be very learned in his wife’s language.  Montesinos says he was a “great linguist.”  They started off quite confidently for Uiticos, taking with them several pieces of velvet and damask, and two cups of gilded silver as presents.  Anxious to secure the honor of being the first to reach the Inca, they traveled as fast as they could to the Chuquichaca bridge, “the key to the valley of Uiticos.”  Here they were detained by the soldiers of the regents.  A day or so later John Sierra, the Inca’s cousin from Cuzco, arrived at the bridge and was allowed to proceed, while the friar and Betanzos were still detained.  John Sierra was welcomed by the Inca and his nobles, and did his best to encourage Sayri Tupac to accept the viceroy’s offer.  Finally John Betanzos and the friar were also sent for and admitted to the presence of the Inca, with the presents which the viceroy had sent.  Sayri Tupac’s first idea was to remain free and independent as he had hitherto done, so he requested the ambassadors to depart immediately with their silver gilt cups.  They were sent back by one of the western routes across the Apurimac.  A few days later, however, after John Sierra had told him some interesting stories of life in Cuzco, the Inca decided to reconsider the matter.  His regents had a long debate, observed the flying of birds and the nature of the weather, but according to Garcilasso “made no inquiries of the devil.”  The omens were favorable and the regents finally decided to allow the Inca to accept the invitation of the viceroy.
