From Villalpando the king departed with his army and went to pitch camp 2 leagues north of Zamora, next to the river and across from Santa María del Viso. The king ordered a search along the river, which was a long bowshot wide, to see if there might be a ford to cross. Among those who went to reconnoitre was a squire called Álvaro Vasques, the Governor of Alcañede. As he was looking for the ford, his horse fell and he with it, and he died there. Others later found a place where they could cross in safety. The next day, 15 May, the king departed, and the whole army crossed by that ford, both on foot and on horseback, so that not one person or animal perished. They set up their camp at once on the far side, not wishing to travel further, weary as they were from the crossing.

Next day they moved on from there, and set up camp close to a town called Corrales, near Zamora, in which was Don Lorenzo Suárez, the Master of Santiago, with many men-at-arms; nevertheless, he did not attempt to skirmish or make any attack.

From there the king departed the next day towards Ciudad Rodrigo, proceeding between Salamanca and Ledesma. As his army was passing by that town, there came forth from Salamanca, where Prince João was with other officers of the marches, Diego López de Angul, the son-in-law of Pero López de Ayala, who had been taken prisoner in Portugal, with light horsemen numbering some 300 between his men and those belonging to others. As he had just recently arrived, he wished to try to achieve something for which he might gain renown. The [king’s] army was well ordered, with its vanguard and wings, the baggage train in the middle, and the king and the duke in the rearguard. Diego López, desiring to do it harm, approached so near to the men of the rearguard that they were close enough to hurl their spears at them.
