Aiguillon (Hundred Years' War).

This fortress was besieged by the French under John, Duke of Normandy, in May, 1347, and was defended by a small English garrison under Sir Walter Manny, who held out bravely till the end of August, repelling numerous assaults. The defeat of Cressy then forced the Duke of Normandy to lead his army northward, and he was compelled to raise the siege.
