Siege of Calais, siege during the Hundred Years’ War on the northern coast of France, lasting from September 4, 1346, to August 4, 1347. After his magnificent victory at the Battle of Crécy in August 1346, Edward III of England marched north and besieged Calais, the closest port to England and directly opposite Dover where the English Channel is narrowest. The siege was an English victory, but it exhausted both sides. A truce was soon declared in the long-running Hundred Years’ War, and that truce held for eight years.

　　Why Edward III wanted Calais After Edward landed in France in summer 1346, he sent his fleet home. He therefore needed a secure port from which he could receive fresh supplies and reinforcements. Calais was ideal. It lay near not only the Cinque Ports of England but also Flemish trade cities such as Antwerp that were then allied with England and could easily resupply Edward’s troops. Calais was surrounded by walls and a double moat and boasted a moated citadel. Its position on the English Channel meant that, once captured, the city could be supplied and defended by English ships easily. It meant that the French could easily defend it, too.

　　Stalemate and starvation Edward’s army numbered around 34,000 men, but such a force was inadequate to penetrate the city’s defenses. The English also had twenty cannon, but these crude devices made no impression on the city’s walls, despite many attempts to breach them.

　　At first, stalemate reigned as the French failed to intercept the English lines of supply, and the English failed to stop French sailors bringing in new supplies. Desertions among Edward’s troops were rife, and Edward replenished his ranks by recruiting prisoners in England who would be pardoned for their service if the siege were successful.

　　By February 1347, however, Edward managed to prevent supplies getting into Calais by sea and dug in for a long siege, starving the 8,000 citizens into surrender. Supplies of fresh water and food were reduced to almost nothing; citizens were reduced to eating vermin and excrement.

　　Jean-Simon Berthélemy: The Courageous Action of Eustache de Saint-Pierre at the Siege of CalaisThe Courageous Action of Eustache de Saint-Pierre at the Siege of Calais, painting by Jean-Simon Berthélemy; in the Museum of Art and Archaeology of Laon, France. It depicts Eustache de Saint-Pierre (in blue on right), the city's oldest burgher, volunteering to die in order to save Calais and its population from destruction by King Edward III (left). Philippa, Edward's wife (center), appeals to him to spare the burghers, who were the city's leaders.(more)The surrender was signaled on August 1, but to spare the city’s inhabitants, Edward insisted on the sacrifice of six of the city’s leaders. As portrayed in Auguste Rodin’s famous sculpture, the six emaciated burghers (leaders), “with bare heads and feet, with ropes round their necks, and the keys of the town and castle in their hands,” offered themselves to the English king so their fellow citizens might live. Only when Edward’s pregnant queen, Philippa of Hainaut, pleaded for mercy on their behalf were the six burghers allowed to live.

Subscribe Now Effects of the siege The French surrender and English victory was a great boon to England during the Hundred Years’ War, and as an English colony the city proved an excellent military base of operations in France. Edward’s finances, however, were now in ruins, and the Black Death was killing large numbers of soldiers, prompting a hastily signed truce with the French. The city was then populated with English settlers and merchants and would remain in English hands until 1558.
