Yusuf I of Granada [SEP] Marinid–Granadan war against Castile
In the spring of 1339, after the expiration of the treaty, hostilities recommenced with Marinid raids into the Castilian countryside. Confrontations ensued between Castile on one side and the two Muslim kingdoms on the other. Granada was invaded by Castilian troops led by Gonzalo Martínez, Master of the Order of Alcántara, who raided Locubín, Alcalá de Benzaide and Priego. In turn, Yusuf led an army of 8,000 in besieging Siles, but was forced to lift the siege by the forces of the Master of the Order of Santiago, Alfonso Méndez de Guzmán. The personal rivalry between Martínez and de Guzmán appears to have caused the former to defect to Yusuf, but he was soon captured by Castillian forces, hung as a traitor and his body burned.
