New pact with Pedro I of Castile. October 19, 1364. Departing from the Ceremonious, Charles II agrees a new treaty with the Castilian at the Casal de Habibi. Yanguas summarizes it as follows: "that if there were to be a cause for dissensions over pledges, brands, thefts, water or irrigation the subjects of both kingdoms, they would be decided by commissioners named by both monarchs and if they could not agree, it would be referred to the knowledge of the king of England or the prince of Wales, as friends and relatives, without being able to make war until the decision of the former, and both kings being obliged to abide by it, which should be arranged under the law of Spain, and in its absence under common law. That the king of Castile would not make peace with the king of Aragon or with his son without including the king of Navarre and his son in it; that he could not make friends with the king of France to the detriment of the king of Navarre; that when the latter needed to send or bring by sea people or weapons for the war in France, ... Castile gave him a place in the port of Fuenterrab ay Oyarzun to load and unload, being able to charter, with his money, up to ten ships in the lordship of Castile; that in the event that the sea threw them to other ports of Castile they would be welcomed; that there would be free reciprocal trade the subjects of both kingdoms, not carrying prohibited goods and paying the customary duties. The councils of Vitoria, Burgos, Logroño and Calahorra swore through representatives, before the procurators of the King of Navarre, that they would do what they could so that D. Pedro de Castilla would keep and fulfill what had been agreed.
