Ferdinand II of Aragon dispatched a force under the Count of Cabra to capture the city of Moclin.

The Count of Cabra, Diego Fernández de Córdoba, reported to the Monarchs that the city of Moclín was defenseless and that it would be easy to capture.

[6] Diego quickly marched at midnight as he thought the Moors would be seized with terror and flee from Moclín by the cover of darkness.

Arriving there on September 2, the Grananda king, Al-Zagal, learned of the upcoming attack and prepared a force of 20,000 cavalry and infantry to fend off the Castilians.

[13] The king abandoned the campaign of Moclín and instead he turned to Cambil and Alhabar, castles southeast of Jaén.
