The Battle of the Sebou River: The Moroccan Counter-Attack
In July, the strategic landscape of the conflict shifted dramatically as Moroccan forces launched a coordinated counter-attack against Portuguese positions. This engagement, centered around the Sebou River, demonstrated a sophisticated use of artillery and tactical positioning that ultimately led to a devastating defeat for the Portuguese forces.
The Strategic Encirclement
The Moroccan offensive was a pincer movement designed to trap the Portuguese. The Sultan's younger brother and the Grand Vizier, Moulay Nasr, led the siege from the north. Simultaneously, the Sultan arrived to besiege the Portuguese from the south bank of the Sebou River, effectively cutting off their land-based options.
The Sultan focused his primary military strength on the Portuguese ships, recognizing that their naval superiority was the only remaining lifeline for the besieged troops. While the Sultan targeted the fleet, his brother focused on investing the fort, tightening the grip on the Portuguese stronghold.

The momentum of the battle shifted within a single hour. A precise and powerful artillery shot from the Sultan's batteries struck one of the Portuguese ships, fundamentally altering the nature of the engagement. With the escape route blocked and the threat from Portuguese cannon ships neutralized, the Sultan ordered twelve pieces of light artillery to move directly to the river shore.
The Moroccan forces then intensified their assault, utilizing explosive grenades—early incendiary or fragmentation devices—thrown close to the Portuguese lines. Under this relentless pressure, the Portuguese began to dismantle their fort in a desperate attempt to flee using small boats.
The Final Assault and Aftermath
As the Portuguese attempted their retreat, the Sultan signaled a final, full-scale attack. The resulting slaughter was so intense that the waters of the Sebou River were said to have turned red. Leo Africanus, a contemporary witness to the siege, described the carnage by stating that for three days, the sea spouted waves of blood.
The cost of the defeat was catastrophic for the Portuguese. The engagement resulted in the loss of 100 ships and the deaths of approximately 4,000 soldiers.
