The battle of Castril was a military engagement between the Granadans and the Castilians who aimed to attack the city of Baza.

When the Granada Sultan Muhammad IX was unable to defend his subjects from Castilian attacks, the Islamic cities submitted to Castile, marking a significant qualitative shift in the dynamic of border warfare and conquests that began in 1436.

By giving up early to the Castilian advance, they were able to escape a futile and agonizing resistance and receive favorable terms in return for their vassalage.

The Adelantado fell dead at the hands of a Moorish knight, who drove his sharp lance deep into his guts.

Arraez displayed great valor during the battle until, wounded by a thrust and an arrow, he bled to death on the field and was carried to his tent on the shoulders of the soldiers and died shortly after.
