The siege of Guînes took place in 1352 when a French army under Geoffrey de Charny unsuccessfully attempted to recapture the French castle at Guînes which had been seized by the English. The strongly fortified castle had been taken by the English during a period of nominal truce and the English king, Edward III, decided to keep it. Charny, leading 4,500 men, retook the town but was unable to retake or blockade the castle. After two months of fierce fighting a large English night attack on the French camp inflicted a heavy defeat and the French withdrew.
