We have already explained how Count Gonçalo and Aires Gonçalves de Figueiredo came to complain a great deal to the Master because of how the castle of Gaia was taken, as you have heard, and the discussions that they had about it. From then until this time they both always showed in their manner that they were unhappy with the Master, so much so that their withdrawal and frequent conversations, in secret and apart from the others, caused people to assume that they wanted to plot something against the Master. Indeed, for this reason there were some who said to the Master: ‘My lord, you should know that there is a rumour that Count Gonçalo and Aires Gonçalves de Figueiredo are not loyally working in your service and want to go over to Coimbra with their men in order to oppose you in the things that you decide to do. Order a warning to be issued about this so that you are not obstructed by them, before they dare start something.’ The Master heard what they told him and worried about what could be happening, but kept quiet without revealing that he knew anything. At this point it started to be claimed that these captains, Diego Gómez Sarmiento, who was in Santarém with 400 lances, Vasco Peres in Alenquer with 150, João Gonçalves in Óbidos with 100, and Count Enrique [Manuel] in Sintra with another 100 lances, were all in league with Juan Duque and with the very Count Pedro [de Trastámara] whom we have mentioned, so that one night they would suddenly all fall on the Master and, whether killed or imprisoned and defeated, he would not be able to escape.

That doctor already alluded to in the chapter that we cited says that the agreement held between them was of this kind: that if they were not able to kill the Master as they had planned, they would one day all go over to the town. Six days after they had cast their lot together in the town, those captains would arrive and to help them Juan Duque would come out with his men in order that they might all accomplish what they had planned.
