The Battle of Cadzand was an early skirmish of the Hundred Years' War fought in 1337. It consisted of a raid on the Flemish island of Cadzand, designed to provoke a reaction and battle from the local garrison and so improve morale in England and amongst King Edward III's continental allies by providing his army with an easy victory. On 9 November Sir Walter Manny, with the advance troops for Edward III's continental invasion, made an attempt to take the city of Sluys, but was driven off. Background For Edward, the war had not progressed as well as had been hoped at the start of the year as vacillation by allies in the Low Countries and Germany had prevented an invasion of France from progressing as intended and setbacks in the Gascon theatre had prevented any advance there either.

Manny understood this well, and after an initial probe against the town failed on 9 November, he retired his 3,700 sailors and soldiers to Cadzand and unleashed them on the local population resulting in several days of feverish looting, raping and pillaging of the isolated villages in the manner of a miniature chevauchée. The garrison of Sluys, led by Sir Guy de Rickenbourg, the illegitimate son of Louis, Count of Nevers, could not let such acts occur so close to them without responding and so crossed the channel between Sluys and the island a few days later and attempted to confront Manny. The English commander was prepared for this and had his men formed up on
