When the battle lines had been drawn up in the manner you have heard and seen depicted, and since we have named a number of the great lords who fought on the side of the King of Castile, it now becomes necessary to indicate in this chapter those whom the King of Portugal had on his side, whose names it is appropriate to set down here, even though they are recorded elsewhere. Their numbers were certainly very small, for nearly all of those great lords had deserted to the enemy, as you have heard at the beginning of [our account of] these events. Some of them had already died, like the admiral, the Count of Viana, Aires Gomes da Silva and other great lords; others remained in Castile, like Fernão Gonçalves, Gonçalo Rodrigues de Sousa, Fernão Gomes da Silva, his brother Afonso Gomes and yet others. Some of them were to be found in the very townships which had declared for the enemy, for example Martim Gonçalves de Ataíde in Chaves, João Afonso Pimentel in Bragança, Álvaro Gonçalves de Moura in Moura, and others throughout the regions of the kingdom. Many accompanied the King of Castile and were present there with him, such as Dom Pedro de Castro, who was the son of Count Álvaro Pérez [de Castro], Dom Pedro Álvares Pereira and his brother Diogo Álvares, Gonçalo Vasques de Azevedo and his son, plus García Rodríguez Taborda and the others whom we have already mentioned.

Since all those had gone over to Castile, who, then, were those who accompanied the King of Portugal in order to help him? Why, there were with him honourable and loyal Portuguese, even though not all of them were of such a lofty rank and status: the most praiseworthy Nuno Álvares Pereira, Constable of Portugal; Álvaro Pereira, marshal of the army; João Rodrigues Pereira; Diogo Lopes Pacheco; his sons João Fernandes (who came later) and Lopo Fernandes; Mem Rodrigues de Vasconcelos and his brother Rui Mendes [de Vasconcelos], who was chief justice of the province of Minho; Lopo Vasques da Cunha; Martim Afonso de Sousa; Vasco Martins de Melo the Elder, Vasco Martins de Melo the Younger, Martim Afonso (along with his sons); João Gomes da Silva;
