Cause

France, unable to maintain its own fleet due to English naval pressure, hired Castilian ships to blockade English ports and disrupt the seaborne trade and military supply routes that England depended on, particularly for its territory in Gascony. Edward III grew frustrated with the effectiveness of this blockade and resolved to confront the Castilian fleet directly.

Event

On 29 August 1350, an English fleet of 50 ships under King Edward III intercepted a Castilian fleet of 47 larger vessels commanded by Charles de la Cerda off Winchelsea. The English won a decisive victory, capturing between 14 and 26 Castilian ships and sinking several more, though significant English lives were lost and only two English vessels were confirmed sunk.

Consequence

Despite the English victory, the battle did not deliver lasting relief to English trade and ports, which continued to face naval harassment from France and its allies. The engagement demonstrated England's vulnerability to maritime disruption but also its capacity to defeat numerically comparable enemy fleets.
