The siege of Calais (4 September 1346 – 3 August 1347) occurred at the conclusion of the Crécy campaign, when an English army under the command of King Edward III of England successfully besieged the French town of Calais during the Edwardian phase of the Hundred Years' War. The English army of some 10,000 men had landed in northern Normandy on 12 July 1346. They embarked on a large-scale raid, or chevauchée, devastating large parts of northern France. On 26 August 1346, fighting on ground of their own choosing, the English inflicted a heavy defeat on a large French army led by their king Philip VI at the Battle of Crécy. A week later the English invested the well-fortified port of Calais, which had a strong garrison under the command of Jean de Vienne. Edward made several unsuccessful attempts to breach the walls or to take the town by assault, either from the land or seaward sides.
