Having seen everyone's proposals, as described here, other arguments besides those already mentioned were added by the Castilians. They submitted that, since the King of Portugal demanded a truce or permanent peace, then, in order to remove all quarrels between the kings and also to eliminate all disagreements which existed with Queen Beatriz, King Fernando's daughter, concerning the entitlement that she claimed to the kingdom, as well as to other things which we could list here, the King of Portugal should have his eldest son marry her. Furthermore, once the marriage was carried out, that son should be called King of Portugal and the Algarve; in such a case the said queen should be given such places in Portugal as befitted the queen of that realm to maintain her upkeep and status. Further, this procedure would help to achieve peace and be beneficial in attaining it, firstly by settling during his own lifetime the status of his son and secondly because, given that his son were [eventually] to become king, he himself would rule over the kingdom at his own pleasure, so that in every sense he would remain king. In addition, with his son firmly assured of the kingdom, so would the desire of a father be fulfilled, namely to see his son well established during his lifetime, for the son's happiness is his triumph.

Likewise, because for the good of that peace it was very fitting that all hindrance and all obstacles be removed, so that God and the world could see that such peace was attained with good and clear intentions, Prince Dinis, King Pedro's son, who had taken the title of king, which was his right to do in Portugal, should be given a dukedom in the realm, with lands and places judged appropriate for whose son he was.

Moreover, if the King of Portugal were to persist in his hatred for and rancour towards the Portuguese who were living in Castile and held their possessions, it would not appear to God or to the world that the peace made was clear and reached with goodwill.
