Siege of the Portuguese Fort: The Conflict on the Loukkos River

Siege of the Portuguese Fort: The Conflict on the Loukkos River

As summer approached, a strategic Portuguese fort became the center of a violent confrontation. Moroccan tribes descended from the surrounding hills to encircle the fortification, initiating a period of constant harassment against the Portuguese forces. The tension escalated in July when Sultan Muhammad arrived to lead the operation, bringing a formidable force to ensure the fort's fall.

The Escalation of Conflict

The military balance was stark. The Portuguese garrison consisted of 1,500 men, while Sultan Muhammad reinforced the Moroccan effort with 4,000 cavalry and a substantial number of infantry. To defend their position, the Portuguese utilized artillery (large-caliber guns) and Caravels—small, highly maneuverable sailing ships—to fire upon the Moroccan forces day and night.

Determined to break the stalemate, the sultan deployed his own cannons to engage the enemy. By mid-August, the conflict had reached a bloody peak, with mounting casualties on both sides leaving the mud of the river stained red.

The Strategic Turning Point

As the siege dragged on, the sultan sought a way to end the deadlock. Acting on the advice of a renegade, he implemented a decisive tactical maneuver: the cutting of oak trees, which were then embedded into the Loukkos river. This created a physical barrier that blocked the river two leagues downstream.

This blockade fundamentally changed the nature of the battle. The Portuguese ships, now trapped and unable to escape or receive reinforcements, lost their strategic advantage. With their naval route severed, the Portuguese were forced to capitulate.

The Peace Treaty and Evacuation

The conflict concluded on August 27 with the signing of a peace treaty. The agreement established a ten-year truce, providing a period of stability between the two powers. As part of the terms, the Portuguese were permitted to evacuate the fort while retaining all of their baggage.
