War with Valencia In 1065, Ferdinand embarked on his last military campaign. He invaded the taifa of Valencia and laid siege to the city itself but did not have the forces to take the city. During the retreat from the city he ambushed and defeated the pursuing forces of the emir Abd al-Malik ibn Abd al-Aziz al-Muẓaffar late in the autumn at the Battle of Paterna. The emir's father-in-law, al-Mamun of Toledo, seized control of Valencia, and the frightened emir of Zaragoza renewed his tribute payments to León. Ferdinand fell ill in November and returned to his kingdom.
