The Battle of Río Salado, fought in 1340 near Tarifa, Cádiz, marked a significant confrontation between the combined forces of Castile and Portugal against the Marinid Sultanate of North Africa and the Nasrid Kingdom of Granada. The Christian coalition, commanded by Alfonso XI of Castile and Afonso IV of Portugal, assembled a formidable army estimated at around 25,000 troops. Their forces included heavy cavalry, skilled infantry, and archers, well-prepared to face the Marinid forces led by Abu al-Hasan Ali, who sought to reclaim lost territories and reinforce their influence in the Iberian Peninsula.

The battlefield, characterized by its rolling hills and proximity to the Mediterranean, provided a crucial tactical advantage to the Christian forces. The Castilian-Portuguese army adopted a strong defensive formation, utilizing their heavy cavalry to create a formidable front line. As the Marinid forces advanced, they relied heavily on cavalry charges and archery, attempting to break through the Christian defenses. However, the disciplined formations of the Castilian knights, backed by infantry support, repelled the initial assaults with remarkable resilience.

A key moment in the battle occurred when the Christian forces executed a well-timed counterattack, utilizing their superior cavalry to encircle the Marinid flanks. This maneuver shattered the Marinid line, leading to a chaotic retreat. The terrain played a pivotal role as well, with the Christians leveraging the higher ground to rain down arrows and crossbow bolts upon their adversaries. The turning point was marked by the strategic use of crossbowmen, who inflicted significant casualties as the Marinids became disorganized under pressure.

As the day progressed, the Christian coalition capitalized on their numerical superiority and tactical cohesion, decisively routing the Marinid forces. The defeat at Río Salado effectively marked the end of the last major Marinid invasion of Iberia, significantly diminishing the threat of Muslim reinforcements from North Africa. The battle's outcome not only secured the borders of Castile and Portugal but also bolstered the morale of Christian forces across the region, paving the way for future military campaigns in the ongoing Reconquista.
